[01:20:45] <rue_house> anyone know if grbl is meant to step on the rising or falling edge of the step pulse?
[01:22:06] <archivist> strange place to ask
[01:23:24] <rue_house> there are only so many places people will know
[01:25:32] <archivist> it is like walking into a rolls royce garage asking how a fiat 500 wheels are made
[01:25:56] <XXCoder> yo archivist did you see link to video?
[01:26:38] <rue_house> well, if they both use the same wheels you can prolly get an answer
[01:26:56] <rue_house> just cause they are different cars dosn't mean every part of them is different
[01:27:06] <archivist> they dont use the same wheels, grbl is a toy
[01:27:31] <rue_house> I'm guessing lots of people using emc use the same microstepping drivrs as repraps
[01:27:42] <archivist> linuxcnc is configureble
[01:27:47] <rue_house> and marlin is just a hack of grbl
[01:28:05] <rue_house> ok, so then
[01:28:30] <archivist> I am sure your answer is in either the docs or source
[01:28:49] <rue_house> what I should ask is if the A4988 stepps on the rising or falling edge
[01:29:06] <archivist> that will be it its docs
[01:29:10] <archivist> in
[01:29:10] <rue_house> then I should assume that grbl does it right, tho thats a stretch
[01:31:19] <rue_house> esp cause the two were probably randomly paired at some point in time
[01:31:26] <rue_house> ok lets try this
[01:31:42] <rue_house> gecko step/dir DC servo controller
[01:31:58] <rue_house> will it have more step latency than a real stepper?
[01:32:06] <archivist> rue_house, one of the regulars tested grbl v linuxcnc he found faults in its implementation of acceleration
[01:32:20] <rue_house> not a surprise to me
[01:32:34] <rue_house> same faults are in marlin, I'm sure of it
[01:32:44] <rue_house> esp when they try to doublestep
[01:33:07] <rue_house> || || || ||
[01:33:12] <archivist> XXCoder, far too much noise of the spindle for me to really hear the Z stepper on its own
[01:33:48] <XXCoder> yeah I can run it whithout spindle, just not now (its 11 am)
[01:33:57] <XXCoder> er pm
[01:34:38] <archivist> mount a bit of steel/whatever to hold your dti
[01:35:14] <XXCoder> it dont have base of any kind, including magnetic
[01:35:18] <XXCoder> its just plastic backing
[01:35:29] <XXCoder> figuring how to do something with it
[01:35:46] <XXCoder> oh yea have cheap holde rlemme see if fit
[01:36:26] <XXCoder> it does
[01:36:29] <archivist> making brackets and things to get around problems is par for the course
[01:43:02] <XXCoder> yea
[01:45:12] <XXCoder> checked
[01:45:19] <XXCoder> surface is pretty flat
[01:45:29] <XXCoder> then it suddenly steps down and stays there
[01:45:31] <XXCoder> then again
[01:45:38] <XXCoder> severial passes each "step"
[02:29:49] <Deejay> moin
[02:29:54] <XXCoder> hey
[02:30:06] <Deejay> hi XXCoder
[02:30:11] <XXCoder> check this out https://youtu.be/zY7nXzcUI9M (loud warning)
[02:31:24] <Deejay> yeah, nice
[02:32:22] <XXCoder> yeah
[02:32:30] <XXCoder> then Z went bit screwy
[02:32:50] <XXCoder> I think its t6560 being very hot got something to do with that.
[02:33:00] <XXCoder> plan to try again, but this time with fan cooling controller
[02:34:14] <archivist> chip may have internal temperature sensing it will then reduce its power
[02:34:52] <XXCoder> probably recuding Z first
[02:35:01] <XXCoder> since x and y didnt seem to have changed in any way
[02:36:20] <pink_vampire> XXCoder: the driver get hot because it hold the stepper
[02:36:42] <XXCoder> hmm yeah holding DO use much more current
[02:36:47] <pink_vampire> try to reduce the current/
[02:36:51] <XXCoder> I plan to try fan on it or something
[02:36:54] <XXCoder> how?
[02:37:12] <pink_vampire> you have dip swiches?
[02:37:15] <XXCoder> curious if you saw video pink? its apparenbtly very loud heh
[02:37:16] <XXCoder> yeah
[02:37:21] <XXCoder> lemme look a second
[02:37:56] <archivist> reducing current is more likely to lose steps, the fault you have
[02:38:19] <Deejay> hi pink_vampire
[02:38:27] <pink_vampire> hi Deejay
[02:38:28] <XXCoder> current dips is 1 and 2 looking now
[02:39:04] <pink_vampire> XXCoder: what do you mean by "current dips is 1 and 2 looking now"??
[02:40:39] <XXCoder> switches on my tb6560 on current
[02:40:44] <XXCoder> its set to 100%
[02:40:59] <XXCoder> whats decay mode
[02:41:51] <archivist> reducing current for hold, dumb idea because it cannot accelerate from hold easily
[02:42:40] <archivist> I think it is a reason many struggle with steppers
[02:43:33] <XXCoder> motors dont seem to get very hot
[02:43:38] <XXCoder> so current I think is fine
[02:43:48] <XXCoder> board itself though...
[02:43:52] <XXCoder> it gets quite toasty lol
[02:44:13] <XXCoder> lemme look at my steppers specs
[02:44:16] <archivist> can you add heatsink
[02:44:23] <XXCoder> see if maybe it needs less current
[02:44:31] <XXCoder> it already has one
[02:45:00] <archivist> very warm steppers is not a problem
[02:45:29] <XXCoder> yeah but suppling too much power to steppers may well be cause of warming bvoard
[02:46:01] <XXCoder> ok lets see
[02:46:06] <XXCoder> mine is 3A apparentlky
[02:46:31] <archivist> failure to add required heatsink ?
[02:46:33] <XXCoder> board max is 3.5A
[02:46:43] <XXCoder> per stepper
[02:47:04] <archivist> I bet rating varies, with/without heatsink
[02:47:09] <XXCoder> yeah
[02:47:15] <XXCoder> it does have fan and heatsink
[02:47:23] <XXCoder> its just not enough apparently
[02:47:46] <XXCoder> its voltage regulars dont have fan but has small heatsinks
[02:47:50] <XXCoder> regulators
[02:48:01] <XXCoder> those get real hot
[02:48:08] <XXCoder> burn finger hot
[02:52:52] <XXCoder> interesting http://www.cnczone.com/forums/stepper-motors-drives/179034-cnc.html
[02:53:07] <XXCoder> I gonna run it without spindle so you guys can hear steppers lol
[02:54:24] <archivist> just nod the Z up and down for a while with the dti measuring where it stops
[02:55:19] <archivist> check z for stiffness and freedom of movement, how heavy is the spindle etc
[02:55:50] <XXCoder> that I already checked, very stiff
[02:56:02] <XXCoder> spindle itself isnt very heavy
[02:56:58] <archivist> find out why it is stiff
[02:58:25] <XXCoder> thought you meant when it is in hold position
[02:58:30] <XXCoder> it moves fine when running
[03:00:10] <pink_vampire> XXCoder: get servos
[03:00:32] <XXCoder> nah not till I run machine very well
[03:00:34] <pink_vampire> do you want to get my machine?
[03:00:43] <XXCoder> it's a learning wheels, if I break its cheap
[03:01:14] <XXCoder> funny how large machine dont quite prep me for running my small one :P
[03:01:30] <XXCoder> though it helped me understand bunch concepts
[03:01:47] <XXCoder> pink_vampire: nah no thanks. :)
[03:03:33] <archivist> XXCoder, I mean measure stiffness without power
[03:04:04] <XXCoder> oh I could move it but not very easily as ballscrew resists
[03:04:13] <XXCoder> on all axes
[03:05:25] <archivist> rotate the ballscrew, measure torque
[03:05:52] <XXCoder> dont have any specific equipment but will try rotate by hand
[03:07:11] <XXCoder> not very hard that way
[03:07:19] <XXCoder> all 3 axles pretty easy to move.
[03:07:32] <XXCoder> Z is slightly harder upwards than downwards, not surpise due to gravity
[03:09:21] <pink_vampire> https://www.youtube.com/watch?v=h9cQaIx2Qeg
[03:09:56] <pink_vampire> made on multi axis cnc machine.
[03:11:08] <XXCoder> wtaching
[03:14:53] <XXCoder> hm
[03:15:03] <XXCoder> easier and safer to buy but if dead broke
[03:15:33] <XXCoder> making belt sander with junk
[03:28:39] <pink_vampire> https://www.youtube.com/watch?v=SSFjeLhbojo&index=20&list=PLQ8Yc12YOB7S3ZA8t2OztGk5qJLJD8G0j
[03:28:49] <pink_vampire> that one even better
[03:30:43] <XXCoder> that videp fps is way too low
[03:30:48] <XXCoder> making me dizzy
[03:31:27] <monkeyisl> yo i'm new to cncworld...what software do i have to consider I'm thinking 3axis cnc and using solidworks(still new)..
[03:32:11] <monkeyisl> i heard powermill and mastercam are popluar.
[03:32:27] <pink_vampire> monkeyisl: I'm using hsm
[03:32:40] <monkeyisl> what's htat/ lol
[03:33:19] <XXCoder> I'm using fusion 360. its pretty nice but cloud based storage ius annoying
[03:33:20] <monkeyisl> inventor hsm?
[03:36:19] <monkeyisl> oh hsm.. looks there is many tutor resource. .. hm.!
[03:36:30] <pink_vampire> hsmworks, hsm express
[03:37:04] <pink_vampire> monkeyisl: ^
[03:37:08] <monkeyisl> http://www.hsmworks.com/ lol
[03:37:20] <pink_vampire> why lol?
[03:37:27] <monkeyisl> thank you! imean
[03:37:37] <XXCoder> hsm express free?
[03:37:39] <monkeyisl> oops it's free?
[03:37:48] <pink_vampire> express is free
[03:37:57] <XXCoder> too bad I dont have solidworkls
[03:38:02] <pink_vampire> works is 3.7K$ year
[03:40:34] <XXCoder> not surpised
[03:42:38] <monkeyisl> i'll try powermill and hsm.. thankss
[03:49:49] <pink_vampire> monkeyisl: do you have a machine?
[03:53:56] <pink_vampire> XXCoder: how the cutting go?
[03:54:18] <XXCoder> it failed as Z inexlictly changed
[03:54:24] <XXCoder> down by I guess 3 mm
[03:54:27] <XXCoder> then again later
[03:54:55] <XXCoder> not constant lowering as it would happen with errors somewhere but nothing then sudden lower, then nothing for while, then again
[03:55:09] <XXCoder> tb6560 was very hot though so I plan to try fan on it and run later.
[03:55:16] <XXCoder> probably not till weekend
[04:05:02] <monkeyisl> pink_vampire : yes i have machine but i'm working on it to make it move......
[04:05:26] <monkeyisl> i'll be driving it until tmr..
[04:05:30] <pink_vampire> monkeyisl: what kind a machine ?
[04:06:07] <monkeyisl> just traditional simple x, y, z (3 axis?) junk.
[04:06:24] <pink_vampire> put it in oil
[04:06:40] <pink_vampire> monkeyisl: any pics?
[04:07:19] <pink_vampire> XXCoder: put it in oil
[04:07:31] <XXCoder> tb6560??
[04:09:14] <monkeyisl> yse i have let me upload
[04:09:16] <pink_vampire> yes
[04:09:24] <pink_vampire> monkeyisl: cool!
[04:09:38] <XXCoder> cooling by oil is known to me but I dont want risk it
[04:18:52] <pink_vampire> if it's none conductive there is no problem
[04:19:13] <XXCoder> I know.
[04:19:23] <XXCoder> I just dont wanna do it heh
[04:19:34] <pink_vampire> why??
[04:19:52] <XXCoder> overkill basically
[04:19:58] <XXCoder> I do plan to build case for ut
[04:20:04] <XXCoder> definitely with good fans.
[04:20:55] <pink_vampire> my drivers with out fan
[04:21:02] <archivist> show a picture of the tb board
[04:21:04] <pink_vampire> work from 10pm
[04:21:13] <pink_vampire> now is 4:55Am
[04:21:23] <pink_vampire> let me see the temp
[04:22:13] <pink_vampire> x28.4c, y29.2c z29.0c
[04:23:18] <pink_vampire> XXCoder: ^^
[04:23:44] <archivist> pink_vampire, what yours are at is not a valid comparison
[04:24:11] <pink_vampire> what do you mean?
[04:24:48] <XXCoder> my tb6560 dont have seperate drivers
[04:24:54] <XXCoder> it drives steppers directly
[04:26:40] <XXCoder> besides evenually I will get much better motors and driver setup and reuse el cheapo electrics kit using my SBR rails and ballscrews
[04:26:47] <XXCoder> its just gathering dust atm lol
[04:33:08] <steel-frame-cnc> hi
[04:33:35] <XXCoder> hey steel
[04:34:25] <steel-frame-cnc> I build a cnc machine and I have some vibrations.
[04:34:28] <steel-frame-cnc> hi XXCoder
[04:34:39] <steel-frame-cnc> you can help me with that?
[04:34:41] <XXCoder> good vibrations? heh kidding
[04:35:01] <steel-frame-cnc> http://i.imgur.com/f3IogGI.png
[04:35:17] <XXCoder> floppy drive cd eh
[04:35:20] <XXCoder> *cnc
[04:35:31] <steel-frame-cnc> yes,
[04:35:42] <archivist> ew, redesign with a better frame
[04:35:53] <XXCoder> better everything really
[04:36:01] <archivist> wrong tools for the job
[04:36:02] <steel-frame-cnc> but it is a steel body.
[04:36:04] <XXCoder> nevertheless
[04:36:13] <XXCoder> anyway steel
[04:36:18] <archivist> steel used badly is bad
[04:36:19] <XXCoder> viobrations? its moving around?
[04:36:25] <steel-frame-cnc> also very acurate stepper motors.
[04:36:44] <XXCoder> yeah it'd have to be, in order to read correct data
[04:36:48] <XXCoder> not strong though
[04:37:21] <steel-frame-cnc> the rails are usa made.
[04:37:31] <XXCoder> the problem>?
[04:37:57] <steel-frame-cnc> the Z axis don't move very good
[04:38:29] <archivist> you have unrealistic expectations for that sort of construction
[04:38:56] <steel-frame-cnc> all I want is to cut wood with it.
[04:39:03] <steel-frame-cnc> or soft metals
[04:39:07] <archivist> find what flexes, where you have play etc
[04:39:25] <archivist> I dont expect that to cut metal
[04:39:36] <steel-frame-cnc> what about wood?
[04:40:50] <steel-frame-cnc> I have also a problem to fit an end mill on my 3V dc direct drive spindle
[04:43:28] <steel-frame-cnc> XXCoder: what do you think?
[04:43:40] <XXCoder> its tough, dunno
[04:43:46] <archivist> I think start again
[04:44:08] <XXCoder> as minium, secure the base, secure the back plate
[04:44:14] <XXCoder> so its more rigid
[04:44:20] <XXCoder> unknown method to secure Z
[04:44:31] <XXCoder> unknown method to secure tool on "spindle"
[04:44:39] <XXCoder> good luck
[04:44:48] <steel-frame-cnc> what about shapeoko?
[04:45:15] <XXCoder> that machine probably good for small area engraving
[04:45:47] <steel-frame-cnc> maybe g0704?
[04:47:00] <XXCoder> cnc machines is similiar with cell phones
[04:47:06] <XXCoder> so many designs, so many possible uses
[04:47:19] <XXCoder> makes it diffult to advise someone to pick one cnc over other
[04:47:24] <steel-frame-cnc> I want nokia 3100
[04:47:59] <steel-frame-cnc> iphone 7 = ?
[04:50:23] <pink_vampire> XXCoder:!!
[04:50:29] <XXCoder> yeah pink?
[04:50:49] <pink_vampire> that was my first cnc machine
[04:51:30] <XXCoder> yeah? cool
[04:51:52] <pink_vampire> yes, the floppy / cd stuff
[04:52:08] <pink_vampire> steel-frame-cnc was me
[04:53:34] <pink_vampire> this is way I have servos on my machine.
[05:05:21] <XXCoder> well your point still does not apply
[05:05:32] <XXCoder> I already stated I plan to evenually upgrade
[05:05:52] <XXCoder> I dont want expensive toy and break it short time later when learning
[05:06:06] <XXCoder> if I burn $20 stepper whatever
[05:06:18] <XXCoder> if I burn $200 servo I'd be po'd off
[05:06:28] <XXCoder> I dont need stress on my hobby,
[05:08:13] <pink_vampire> it is very complicated to burn a servo motor
[05:08:47] <XXCoder> and btw sockpuppeting is very immature way to create support for your argument
[05:09:10] <pink_vampire> especially if you take one that suitable to the torque that you need
[05:09:19] <pink_vampire> what do you mean??
[05:09:24] <XXCoder> sure. just not now.
[05:09:49] <pink_vampire> ok.
[05:10:15] <pink_vampire> test the torque that you need for lifting the Z axis,
[05:10:33] <XXCoder> it can easily do it. same stepper can move entire gantry
[05:10:35] <pink_vampire> then read what is the nominal torque of the motor.
[05:10:41] <XXCoder> I have to push i9t pretty hard to stall it
[05:11:27] <pink_vampire> but you are loosing steps.
[05:11:31] <XXCoder> no, movement is not problem, pretty sure its just controller overheating
[05:11:37] <XXCoder> not in constant basis
[05:12:19] <archivist> XXCoder, not necessarily the right way to diagnose
[05:12:27] <pink_vampire> you can loose steps is you have vibrations. and chattering.
[05:12:34] <pink_vampire> is = if
[05:13:12] <XXCoder> yeah I can only detect vibrations. I cant tell if its from what
[05:13:31] <XXCoder> though it consiently sets z correctly besides 2 sudden drops
[05:13:50] <XXCoder> archivist: yeah I plan to just test again with fan on tb6560
[05:13:54] <XXCoder> see if its any better
[05:14:00] <XXCoder> its just scrap wood
[05:16:06] <archivist> loose coupling between stepper shaft and ballscrew
[05:16:34] <XXCoder> possible.
[05:16:40] <XXCoder> will check when can later
[05:16:52] <XXCoder> odd that it would slip only once a while but yeah
[05:24:47] <pink_vampire> set slower feed to the Z axis, this way you will get better holding.
[05:25:07] <XXCoder> maybe. maybe not. if coupler is slipping it dont matter how slow its moving
[05:25:27] <pink_vampire> also move to full step if you are on micro step or half step
[05:31:02] <pink_vampire> trrrrrrrrrrrr
[05:31:18] <pink_vampire> this is all I hear:(
[05:31:34] <XXCoder> my video?
[05:31:47] <XXCoder> that spindle vobrates so hard. 27000 rpm lol
[05:34:34] <pink_vampire> no
[05:34:52] <pink_vampire> my machine work for hours!!
[05:35:06] <XXCoder> long job eh
[05:36:01] <pink_vampire> 1.8M lines
[05:36:12] <XXCoder> wow
[05:36:18] <minibnz> impressive..
[05:36:20] <XXCoder> making 3d profile of some kind?
[05:36:24] <XXCoder> hey mini
[05:36:25] <pink_vampire> no
[05:36:39] <minibnz> curves? lots of curves?
[05:36:56] <pink_vampire> 0.1 depth cut
[05:36:59] <minibnz> or is that a shite load of comments :)
[05:37:06] <pink_vampire> 0.1 side load.
[05:37:18] <pink_vampire> mm
[05:37:19] <minibnz> ahh small load high speed?
[05:37:21] <pink_vampire> 0.1mm
[05:37:28] <pink_vampire> 1000rpm
[05:37:45] <pink_vampire> defective Z axis
[05:41:14] <minibnz> i noticed a problem with my Z axis the other day.. the rack is moving up and down before the head moves.. gotta find a way to attach that better.. im considering a bit of devcon epoxy... it should hold it but it might hold too well.. that and i might need to lower my Z travel now i have collet holders i dont think i can reach the bed with a 2mm cutter without the rack and pinion seperating..
[05:41:56] <XXCoder> pink_vampire: plan to repair your Z axis?
[05:42:09] <minibnz> still finding problems this far into my build makes me think it will never end....
[05:42:22] <pink_vampire> maybe to install H rails.
[05:43:40] <XXCoder> remove old key rails and put that in eh
[06:19:36] <XXCoder> pink_vampire: so its best to just add H rails
[06:19:44] <XXCoder> cheaper at end
[06:20:05] <pink_vampire> cheaper and better.
[06:20:47] <pink_vampire> now i need to find someone with bigger machine in ny that will do it for me.
[06:21:26] <XXCoder> well hope you find someone
[06:21:35] <XXCoder> gonna go sleep laters
[06:28:15] <pink_vampire> here it's 7am.
[06:28:33] <pink_vampire> the machine still running
[06:37:21] <mase-tech> Hi peps
[06:39:46] <mase-tech> 3h of Classical electromagnetism or classical electrodynamics is heavy stuff I can tell
[08:04:49] <gregcnc> pink why doesn't your g0704 run 2kRPM like spec?
[08:09:22] <jdh> mine runs faster than that
[08:16:28] <Valen> w00t got my servo driver talking again
[08:16:40] <Valen> helps when you connect tx to rx on rs232 things...duh
[09:17:47] <gregcnc> www.ebay.com/itm/251946154026 anyone used these on a VFD input? I'd like a spindle power reference.
[09:20:03] <archivist> nice idea but Accuracy: 1%+/- 2 words never seen accuracy quoted in words :)
[09:22:21] <gregcnc> ah I didn't catch, 2 hz update would be a bit slow
[09:22:57] <archivist> but you could use the loop in linuxcnc to measure power maybe
[09:24:41] <gregcnc> the lathe VFD has a 0-24V load% output which I'll connect to a meter in linuxcnc, but this is for an Emco mill.
[09:25:48] <enleth> even chinese VFDs have analog outputs nowadays, they do work
[09:26:11] <archivist> I was thinking a spindle encoder and pwm would tell you in a roundabout way
[09:33:16] <_methods> spindle power or spindle load?
[09:34:19] <gregcnc> right spindle load really, current as a percentage of current available at RPM. AC makes this a bit tricky
[09:35:18] <minibnz> that unit you linked will give you the current load probably in watts.
[09:37:05] <minibnz> you wont get that much info from the pwm unless you can measure (or know) the motor's reactance value, they are kinda hard to measure on the bench static.. i think the simplest way is the inline meter
[09:38:08] <minibnz> oh its a contactless pickup.. thats nice.. you still get the same infomation
[09:38:33] <gregcnc> maybe current is all that matters
[09:39:23] <minibnz> current and voltage are both important.. but you are right current is more useful if thats all you have.
[09:39:38] <minibnz> shame that meter only samples at 2hz.
[09:41:30] <minibnz> with AC you might need to know the power factor. ie how far behind the current is to the voltage... this can be useful if it trips breakers and also if you correct for it you use less power (ie smaller power bill)
[09:43:01] <minibnz> if it sampled faster and has the output to log it would be nice to see the power curve throughout the full rotation of the motor so you can use that info to tell if the cutter is blunt..
[09:43:24] <minibnz> you might still get that from that meter at 2hz..
[09:44:38] <gregcnc> this isn't a critical need, <1kW spindle with so little power i'd like to see how hard it's working.
[09:45:44] <minibnz> yeah thats what i was thinking too.. i might build me something and see whats to be learned :)
[09:50:03] <minibnz> you would only need to sample things at 60hz per 1000 rpm and you would get 4 samples per revolution.. you could tell if one flute of the cutter was sharper or blunter.. only 2 channels to sample volts and current so 120 samples per second of data you could easily dump that via serial usb or real com port to be logged or actioned on in EMC
[09:54:06] <gregcnc> i think tool runout would preclude useful information about individual flutes. average is used all the time.
[09:56:32] <minibnz> yeah thats a good point
[09:58:55] <enleth> wouldn't runout itself also be measurable that way?
[09:59:06] <enleth> as small variations in chip load, that is
[10:00:52] <minibnz> bluntness would be available as a change in the delta regardless of value/variable used..
[10:01:40] <minibnz> and if you could measure it that way maybe we could rotate the cutter in the holder and see if it reduces or increases..
[10:05:57] <jdh> while cutting your perfectly homogenous material in the same orientation, doc, woc
[10:08:38] <jdh> if you have a 2 flute 12.000mm HSS end mill and you cut a slot 6mm deep in 6061, how wide is the slot after 200mm
[10:10:57] <minibnz> just a smudge mark deep?
[10:12:26] <CaptHindsight> jdh: is the cutting tool spinning or held stationary?
[10:12:37] <jdh> did it take more current because a flute is worn, because the end mill is now bigger? or less because the bearing lube warmed up?
[10:13:48] <jdh> spinning for this admittedly stupid exercise.
[10:14:51] <gregcnc> if trying to collect detailed cutting data there is a lot to consider
[10:14:54] <minibnz> wonder if it would be usefull to detect a broken cutter.. ie full one snap where the load drops a lot?
[10:15:30] <gregcnc> how does it know it didn't just exit a cut?
[10:15:57] <minibnz> ahh yeah it would need to be gated against the gcode.
[10:16:44] <jdh> post-cut check before tool change
[10:17:05] <CaptHindsight> dia of the tool, angular momentum, inertia are also factors
[10:17:24] <gregcnc> all this stuff is actually done industry to some extent Sometimes it's laser measurement, someitmes it tool break sensors, sometimes it' the operator watching for sparks or the load meter.
[10:17:38] <gregcnc> or you just wait until all the tools are borken and it's obvious
[10:18:15] <archivist> lube failure, built up edge starts happening, force rises
[10:19:18] <jdh> broken drill befor tap would suck
[10:20:07] <minibnz> i guess you could use a touch off sensor to detect that
[10:20:26] <gregcnc> broken drill on lathe taking out the rough boring bar, the finish boring bar, the grooving bar all carbide sucks
[10:20:37] <jdh> heh
[10:23:42] <minibnz> might see if the carousel modules can be modded to support that, touchoff and measure, would also be able to detect tool slip in the collets or the tool holders in the spindle. at the moment my holders can pull out if i dont adjust it up tight..
[10:24:16] <minibnz> i could do it in gcode esasily enough
[10:31:20] <minibnz> ok its bedtime for me its 1am.. talk with you all later..
[10:31:28] <mase-tech> minibnz: gcode from g-unit ? :D

[11:31:50] <cradek> no, the mori
[11:32:23] <CaptHindsight> I think I got my Matsuura 760 from that guy
[11:33:10] <CaptHindsight> he works for an automation co but doesn't know much about controls, at least he didn't show any evidence of it with his 760 retrofit
[11:35:00] <CaptHindsight> he's like the guy that buys old cars and only gets 50% through a restoration and then his wife tells him to make room in the garage since he's never going to finish it
[11:36:43] <CaptHindsight> and the reason he stalled out is that he can't get the plug wiring right or some bone head thing is in backwards
[11:42:23] <Polymorphism> http://www.probotix.com/V90-MK2
[11:42:26] <Polymorphism> what about this machine?
[11:42:42] <Polymorphism> It comes with a nice controller, it comes with a linux PC
[11:42:50] <Polymorphism> looks turn key, nice support, USA made
[11:43:25] <Polymorphism> dual y drive stepper
[11:47:22] <jdh> buy it!
[11:47:54] <jdh> and a spindle + vfd
[11:48:44] <Polymorphism> was planning for spindle///vfd combo
[11:48:50] <Polymorphism> going chinese if I need to purchase
[11:48:56] <Polymorphism> ~275 shipped
[11:49:07] <Polymorphism> I'm adding up all options now
[11:49:37] <Polymorphism> I could also get the similar sized raptor mini and use the probotix controller + pre-wired motorsd
[11:49:55] <jdh> chips.
[11:49:58] <Polymorphism> or, x6-2200l for turn key chinese, save about ~1000
[11:50:09] <Polymorphism> or cheap ebay 6040
[11:50:12] <Polymorphism> it works great for loetmichael
[11:50:16] <Polymorphism> Loetmichel,
[11:50:16] <jdh> you could have bden making chips for months
[11:50:42] <Polymorphism> =\
[11:51:03] <Polymorphism> Well thats partly why I moved ahead and started looking at software as well
[11:51:08] <Polymorphism> that seems easier to choose
[11:51:10] <Polymorphism> and less commitment
[11:51:13] <jdh> could be working on the next one already
[11:51:41] <Loetmichel> jdh: weeks at least
[11:51:57] <Loetmichel> some ppl are so indecisive it hurts
[11:52:19] <Polymorphism> hey Loetmichel , did you see the machine I found? http://www.probotix.com/V90-MK2
[11:52:26] <Polymorphism> it looks like it might be a pretty good deal
[11:52:32] <Polymorphism> it even comes with a computer
[11:53:17] <Polymorphism> is it worth 300 extra for an auto tool length sensor
[11:54:57] <Polymorphism> without ATLS its 3000 shipped with 80mm mount + ebay china spindle + vfd total cost
[11:55:03] <Polymorphism> $3300 turn key
[11:55:50] <Polymorphism> x6-2200l $2500 turn key similar dimensions
[11:56:02] <Polymorphism> ebay 6040 $1400 similar dimensions turn key
[11:57:31] <Polymorphism> cncrouterparts desktop complete machine ~2500 shipped
[11:58:50] <Polymorphism> too expensive, but worth mentioning is raptor 30x36 larger model ~$4000 total shipped including spindle wiring etc
[11:59:27] <Polymorphism> pulling up raptor mini PI... 1 sec
[12:01:00] <Polymorphism> Mini raptor 2375 shipped for frame + motor +ps +driver kit from George
[12:01:12] <Polymorphism> plus 300 shipped for vfd + spindle + wiring + enclosure.... call it
[12:01:30] <Polymorphism> 2800 total, sounds quite possible
[12:01:33] <Polymorphism> once its all built
[12:01:47] <Polymorphism> none of these consider tools, dust collection, software, etc
[12:01:52] <gregcnc> Capthindsight, do it like the pickers or Rick Harrison, walk in to the office wave around 20 C notes and take it home
[12:01:54] <Polymorphism> and only the probotix includes a computer
[12:02:13] <Polymorphism> one last option would be the raptor mini, but not with georges electronics
[12:02:17] <Polymorphism> I could use the probotix controller
[12:02:22] <Polymorphism> that would be... 1 sec for total
[12:03:44] <Frank__15> guysss sorry to interrupt, but do any of you have any kind of experience trying to correct 0.01mm or 0.0005in of twist on a rail surface that is 1.5 inches wide? across 8 inches long of the twist
[12:04:07] <Polymorphism> $3000 for that final option
[12:04:33] <Polymorphism> and its a known 3000, as the box is built and wired
[12:04:46] <Polymorphism> the raptor mini w/ george electronics + my housing wiring etc could climb to 3k as well I would think
[12:05:11] <Polymorphism> plus tools, collet set, spoilboard, dust collection, software, need to consider
[12:05:17] <djdelorie> Frank__15: what's the setup and how are you measuring the twist?
[12:07:34] <Frank__15> thanks djdelorie, well i am building a 2.4mts long router, and i sent to machine the hole thing, but the rails whre the hiwin 25mm rails go are twisted about 0.01mm reading from the hiwin block wich is 57mm wide, and with a starret 98-8 8 inch or 200mm long precision level,
[12:07:58] <Frank__15> its just a spot about 300mm long
[12:08:12] <archivist> that is miniscule for woodwork though
[12:08:20] <Frank__15> but i have 0 experience in this topic, so i am afraid of screwing up
[12:08:40] <archivist> leave it as is, finish the build
[12:09:10] <archivist> that is significantly better than many achieve
[12:09:27] <djdelorie> you could likely untwist that with a few pieces of paper under one of the legs :-)
[12:10:04] <Frank__15> yes, but its not because of tolerances in work, its because i dont want the hiwin rails to have any stress, and 0.01 is on the rail wide, if you go to the block, then the error is about 0.03mm
[12:10:55] <Frank__15> but that would twist about 1.3mts long portion of the rail, the issue is particularly on that spot, no matter how i move the structure
[12:11:44] <djdelorie> if you're saying the rails don't sit flat on the side of the machine, you can shim it using brass shims
[12:11:56] <archivist> undo the rail at that point shim under it
[12:12:07] <Frank__15> yes, but the smallest shims i can get are 0.025mm
[12:12:26] <djdelorie> aluminum foil is thinner
[12:12:28] <Frank__15> here i cant get 0.01 or 0.005 which would be better
[12:12:41] <Frank__15> you mean the cooking stuffż?
[12:12:44] <djdelorie> yup
[12:12:47] <djdelorie> measure it :-)
[12:12:59] <Frank__15> my caliper doesnt have that accuracy
[12:13:00] <Frank__15> lol
[12:13:05] <Frank__15> thanks for the tip
[12:13:29] <Frank__15> actually the 0.025stuff i can get is aluminum, but ill try with the cooking stuff
[12:13:50] <djdelorie> also try plastic wrap, cellophane tape, etc.
[12:14:01] <djdelorie> not as durable but might work.
[12:14:16] <djdelorie> Or just sand the other side a bit to remove some metal
[12:14:46] <archivist> or use an engineers scraper to get flat
[12:15:14] <djdelorie> but really, you're talking about an insignificant amount of twist IMHO. See if the hiwin specs have a "max twist" rating
[12:16:07] <Frank__15> thats the frustrating part, they only specify height tolerance (0.127mm) and parallelism tolerance (0.03mm)
[12:16:18] <Frank__15> and i ahve the problem on both rails T_T
[12:17:12] <djdelorie> if the tolerance is 0.03 and you're at 0.01, you're done
[12:19:15] <Frank__15> but thats paralelism, :D
[12:19:26] <Frank__15> i guess your right thou
[12:25:21] <membiblio> greetings
[12:25:55] <membiblio> in linuxcnc 2.7 is the issue with xfce4-panel not starting properly known with a fix or some other status?
[12:26:30] <Polymorphism> I'm making a table
[12:33:28] <Polymorphism> http://pastebin.com/raw/LXNHNTy8
[12:33:30] <Polymorphism> here is the table
[12:33:32] <Polymorphism> let me know what you think
[12:34:13] <Polymorphism> I figured the cheapest and the most expensive options should be on there
[12:34:17] <Polymorphism> to put others into context
[12:34:35] <Polymorphism> and also make me aware if I'm approaching a point where it's just a little bit more for a lot more perfromance///work arwsa
[12:34:54] <Polymorphism> there is one option missing from visionengravers
[12:34:57] <Polymorphism> I just found it yesterday
[12:35:01] <Polymorphism> waiting to hear back from the company
[12:45:53] <CaptHindsight> Tom_itx: ever been to the hackerpace in Wichita?
[12:49:22] * unfy noms the food
[12:49:48] <unfy> this week's goals: finish air compressor be quite box, look into alignment issues, debate lash solutions
[12:52:38] <unfy> oh, i should prolly buy some nema23's or the drivers for them
[12:58:03] * djdelorie is curious to hear from someone who *actually* found clearpath servos to be cheaper than steppers of the same class...
[13:02:04] <unfy> see, i wanna look at servos... but.... when I know I can get 3 or 4 axis of cheap import ~400oz/in nema23's with drivers for less than $200... kinda hard to ignore ._.
[13:03:13] <alex4nder> unfy: what kind of application?
[13:03:53] <unfy> small cnc mill, prolly AL / brass / plexi has 'hardest' materials it'll ever see
[13:04:10] <alex4nder> ah
[13:05:24] <alex4nder> I'm running 175 oz-in motors on my taig.
[13:06:07] <unfy> i'm mildly impressed at how strong the lil 70-80oz/in nema17's have been for the hardware store thing i've been playing with.
[13:06:45] <unfy> having played with smaller motors, i wouldn't mind playing with larger ones next. although the 1600oz/in nema34's are tempting too D:
[13:06:47] <maxcnc> hi all from a summer sunny germany
[13:07:03] <unfy> sunny nebraska here! after a week of rain \o/
[13:07:12] <alex4nder> unfy: I went smaller, because the mill I have has 20 TPI screws
[13:07:15] <unfy> don't get me wrong, i love the rain - but it makes melting metal and stuff difficult
[13:07:22] <alex4nder> so speed/accel seemed like a better idea than a bunch of torque
[13:07:32] <maxcnc> unfy: search for wantai motors on ebay
[13:07:50] <mase-tech> Hi maxcnc how is it going
[13:07:51] <unfy> max: seen them, but if they're suggested then they'll get prefernce
[13:08:29] <alex4nder> djdelorie: I could see using these clearpath modules to run my 4th-axis/lathe spindle
[13:08:46] <maxcnc> unfy: i do alot of his stuff
[13:09:08] <maxcnc> unfy: the leadshie replicas are ok
[13:09:22] <djdelorie> I want an excuse to use them, because that's basically the same setup as my hacked-together machine, but I've yet to see a real world example of their "better than same-priced stepper solutions" claim
[13:09:24] <mase-tech> maxcnc: I bought the recommanded spindel from kress
[13:09:35] <maxcnc> cool
[13:10:03] <djdelorie> even my 3D printer can lose steps when I have to clear a jammed filament. I HATE LOSING STEPS! But I also have heat problems on that machine...
[13:10:06] <maxcnc> no go one with the rails
[13:10:15] <mase-tech> The other things must wait till I have more time, because the school eat to much time
[13:10:25] <djdelorie> but I don't worry about losing steps on the cnc even when manually changing bits, it just works :-)
[13:10:51] <maxcnc> high voltige is better to no steplos
[13:11:03] <maxcnc> i mainly use 72V
[13:11:13] <djdelorie> my servos are 160v

[13:12:11] <unfy> poly: *facepalm* ... buy something!
[13:12:14] <maxcnc> unfy: what is the workplace to be

[13:12:58] <maxcnc> unfy: there are large pickups in the usa
[13:13:03] <Polymorphism> Sync, =\
[13:13:20] <Polymorphism> this is starting to feel like its gone on too long
[13:13:25] <Polymorphism> thats why I made this forum post
[13:13:35] <Polymorphism> and tried to bring all the info I've gathered into one place
[13:13:40] <maxcnc> unfy: sp rack pinion decision
[13:13:45] <Polymorphism> its been a learning experience for me also
[13:14:02] <Polymorphism> about tools, tool length, changings, work holding, dust extraction, cad + cam, etc
[13:14:04] <maxcnc> Polymorphism: software without a mashine is stupid
[13:14:31] <maxcnc> Polymorphism: you can stay all free at your need
[13:14:34] <Polymorphism> I'm going to be using either Fusion360, freecad, RS DS mech, onshape, freecad, inkscape, cambam, meshcam
[13:14:36] <Polymorphism> or some combination
[13:14:39] <Polymorphism> for cad + cam
[13:14:48] <Polymorphism> F360 might do everything in one program free
[13:15:08] <Polymorphism> oh and also eagle for pcb + pcb2 gcode
[13:15:19] <maxcnc> keep in mind f360 holds all you models in the vcomunity cloud
[13:15:26] <djdelorie> I've been trying Fusion360 for my machine, even though it won't run on my main desktop (Fedora)
[13:15:42] <Polymorphism> f360 didnt work on my laptop sadly
[13:15:46] <Polymorphism> 4500mhd gfx
[13:15:51] <Polymorphism> it loaded but
[13:15:54] <Polymorphism> things were invisible
[13:16:00] <Polymorphism> RS Dreamspark mech worked nicely
[13:16:04] <Polymorphism> even on the old gfx
[13:16:14] <djdelorie> and I dropped eagle for gEDA long ago, but I'm biased :-)
[13:16:29] <Polymorphism> I have no preference yet... I'll look into gEDA
[13:16:38] <djdelorie> I tried pycam recently but couldn't figure out how to cut a simple outline
[13:16:51] <Polymorphism> how do you generate gcode from pcb
[13:16:52] <maxcnc> eagle is cool and fast for small boards
[13:16:54] <Polymorphism> is that part of gEDA
[13:17:03] <djdelorie> File->Export->GCode
[13:17:08] <Polymorphism> that is cool
[13:17:13] <Polymorphism> maybe I should use that for pcb
[13:17:16] <djdelorie> maxcnc: I agree, but once you hit that "small" limit...
[13:17:30] <Polymorphism> is eagle free for small boards or something?
[13:17:31] <djdelorie> Poly: gEDA has one big advantage for you - if it doesn't do what you want, you can change it :-)
[13:17:38] <maxcnc> at eagle you can decide some more as offsets freeruns and spacing
[13:17:41] <djdelorie> yeah, eagle has a limit for free
[13:18:09] <djdelorie> and the first part I tried to use - a DB25 - had the wrong dimensions :-P
[13:18:20] <maxcnc> its 100x80mm
[13:18:34] <maxcnc> so half FP4
[13:18:52] <djdelorie> gEDA's limit - for 64-bit builds - is approx "size of the universe". I've tested up to 1/4 mile per edge ;-)
[13:19:06] <djdelorie> we suggest you keep it under a few meters...
[13:19:35] <Polymorphism> I like that RS DesignSpark mechanical has free 3d components you can import - seems like it would save me time not having to model all of the jacks etc I will be using in designs.
[13:19:36] <maxcnc> unfy: still on
[13:19:44] <Polymorphism> thought it had a pcb plugin too but maybe that costs extra, need to look into it
[13:20:05] <djdelorie> Poly: that works until you need something custom. ALWAYS assume you'll have to learn how to design your own library elements, regardless of their marketing spew.
[13:20:26] <Polymorphism> ok, that makes sense
[13:20:36] <Polymorphism> I already noticed they didnt have the amphenol usb type B connectors I use
[13:21:10] <unfy> max: at work, someone needed something. the motors are just for a machine 'to play with'. i've been learning lots on my current bottom dollar build and learning what my requirements are or what i'd like in the future etc.
[13:21:15] <maxcnc> did you use the new lib on usb con
[13:21:19] <djdelorie> and even if they have a model for you, always double check it - they're not always correct
[13:22:13] <djdelorie> unfy: clearpath have an advantage in the "time to deploy" category, but you do miss out on a lot of the "I learned something today" side.
[13:22:37] <Polymorphism> the push//pull tool made it so easy to design control panels it seems too good to be true... not sure how inkscape or a 2d app would compare. I just need 2d designing really for these panels so the 3d cad seems like overkill. but if its easier to use and will work why not
[13:22:40] <maxcnc> unfy: high gear low motors hoghvolts short cabels equals max force high speed
[13:22:41] <djdelorie> tbh, designing your own bldc driver from scratch is WAY on the other side of that balance :-)
[13:22:44] <Polymorphism> especially if it could make a toolpath CAM too
[13:22:56] <Polymorphism> its just confusing because I end up with a 3d representation of the enclosure panel
[13:23:01] <Polymorphism> when all I need is a 2d drawing of it
[13:23:04] <Polymorphism> to mill the cuts...
[13:23:12] <Polymorphism> part of the confusion is from never having used a cnc , I'm sure./
[13:23:20] <unfy> dj: i'll mix and match pieces, don't care to go too low on the learning process :D
[13:23:23] <djdelorie> Poly: Fusion has a 2d mode that works with CAM, but IIRC heekscad does 2.5D pretty well
[13:23:57] <djdelorie> unfy: if you want to go crazy, my design files are at: http://www.delorie.com/electronics/bldc/
[13:24:25] <unfy> dj: no no, i've got far too many projects going on at once as is :P appreciate the offer tho
[13:24:30] <djdelorie> Poly: you could almost hand-code simple 2.5D patterns, perhaps with a software library
[13:24:30] <maxcnc> djdelorie: uploaded a new heeks to the nigtly builds
[13:24:51] <djdelorie> maxcnc: I still run Fedora 20, that typically makes new builds *harder* for me :-P
[13:25:09] <djdelorie> but... pointer?
[13:25:50] <maxcnc> new strat on awal code based
[13:26:19] <Polymorphism> djdelorie, the ideal would be my entire product modeled
[13:26:23] <maxcnc> 2.5D cross run
[13:26:25] <Polymorphism> and the ability to export single panels fcrom the enclosure
[13:26:28] <Polymorphism> to the cnc for routing
[13:26:34] <djdelorie> you want Fusion360 then :-)
[13:26:34] <Polymorphism> but be able to see the entire assembly as a whole
[13:26:59] <Sync> why would you still run F20
[13:27:05] <Polymorphism> ok, I'll look into that option more
[13:27:06] <Sync> that's 3 years old now, iirc
[13:27:20] <unfy> because if it's not broke, don't fix it.
[13:27:22] <djdelorie> my setup is so custom that upgrades take a minimum of 3 days, and I have a lot of daily stuff that relies on this machine being usable
[13:27:35] <djdelorie> I fear and loathe major version upgrades
[13:27:37] <maxcnc> ok im off familie time
[13:27:42] <maxcnc> Gn8
[13:27:47] <unfy> \o
[13:28:18] <djdelorie> I'm due for one, though. Even I can only stand being so far behind...
[13:29:12] <djdelorie> my CNC still runs LinuxCNC 2.4.6 too, and it complains that the OS isn't supported each time I boot...
[13:29:18] <mase-tech> djdelorie: why use fedora ? I would recommand arch and trumbleweed
[13:29:23] <archivist> wot! not running djgpp on dos ?
[13:29:31] <djdelorie> BTW - rotating the XY plane on my CNC in LinuxCNC was not as simple as I'd expected
[13:29:34] * archivist ducks
[13:29:36] <djdelorie> mase-tech: I work for Red Hat :-)
[13:29:49] <unfy> archivist: too obvious, try harder (facepalm)
[13:29:50] <djdelorie> archivist: DJGPP is still going strong but doesn't do what I need these days
[13:30:02] <mase-tech> djdelorie: Like u mean for a living
[13:30:11] <jdh> I have a RHEL 1 box still
[13:30:12] <djdelorie> mase-tech: yes. I'm in the glibc group
[13:30:19] <mase-tech> Holymoly
[13:30:25] <jdh> err.. no, it is FC1
[13:30:53] <djdelorie> my oldest running OS at the moment is FC3
[13:31:19] <jdh> mine is rsx11m+
[13:32:00] <jdh> I win.... or is it lose..
[13:33:28] <djdelorie> jdh: I have a machine in my office that runs... well, it has a processor *board* with basic in microcode, I'm not sure what you'd call it... from 1977. I'm too scared to turn it on but it worked last time I did :-)
[13:33:30] <archivist> jdh I have some manuals for rsx
[13:34:07] <jdh> mine is running 24x7
[13:34:18] <archivist> my PET is a bit sick, fires up but 0bytes free
[13:34:24] <djdelorie> I assumed that. My oldest 24x7 is that FC3 machine
[13:35:31] <jdh> I have one with an old rt kernel
[13:35:36] <Sync> oh god, rsx11
[13:35:52] <djdelorie> my second oldest 24x7 linux box is... my furnace! Running 2.6.18 since 2006
[13:36:46] <jdh> nice
[13:37:08] <mase-tech> lol are u kiding me
[13:37:29] <jdh> 2.4.22 from 2003 on this one
[13:37:46] <djdelorie> mase-tech: http://www.delorie.com/house/furnace/
[13:38:15] <mase-tech> nice
[13:38:16] <djdelorie> I even migrated it almost as-is to the new geothermal unit when we upgraded that
[13:38:35] <Polymorphism> do you use PID for this djdelorie
[13:38:39] <djdelorie> added a 12 channel thermocouple unit to it to monitor all the water temps
[13:39:13] <djdelorie> Poly: no, strictly on-off. The cycle time is way longer than the house's response time so PID is not needed
[13:39:23] <Polymorphism> ah ok
[13:39:40] <jdh> 2.2.28-ttl on the othet, dec. 2001
[13:39:54] <djdelorie> on cold winter days, the system can run for days on end without stopping, but typically it runs for an hour or so per cycle
[13:40:55] <djdelorie> Poly: plus for this type of system (compressor) it's important to limit the number of times you turn the unit on or off. There's code to sync the zones to reduce the number of cycles.
[13:41:31] <Polymorphism> is this written in c? and what did you use for the microcontroller
[13:41:42] <djdelorie> BTW that's why it runs linux - the factory controller turned the AC on/off too often, burned it out in one season
[13:41:48] <Polymorphism> is that the r8c
[13:42:05] <Polymorphism> that sounds like bad design
[13:42:10] <Polymorphism> the original
[13:42:10] <djdelorie> The main code is in C++ and runs on a gumstix (ARM). Each zone has an r8c for communications, that code is in asm
[13:42:43] <djdelorie> plus an r8c for the thermocouple unit, and an r8c to drive the furnace signals
[13:42:48] <jdh> wow. haven't heard gumstix in a while
[13:43:07] * Polymorphism has never heard @_@
[13:43:07] <djdelorie> they're still around and lively, but mine is one of the early models (connex)
[13:43:26] <djdelorie> www.gumstix.com
[13:43:57] <Sync> oh god r8c
[13:43:58] <Polymorphism> rpi, bbb, arduino, chip, gumstix....
[13:43:59] <djdelorie> in this photo, the gumstix is between the main board and the ethernet board: http://www.delorie.com/house/furnace/board-full.jpg
[13:44:07] <djdelorie> Sync: r8c is one of my favorite chips :-)
[13:44:11] <jdh> still pricey
[13:44:22] <Polymorphism> too many options =\ and then I read using a linux system o n module is my best bet for new product
[13:44:37] <Polymorphism> djdelorie, I take it you outsourced these pcbs?
[13:45:04] <djdelorie> I designed them myself but sent them out to be manufactured, yes
[13:45:23] <Sync> they never really appealed to me djdelorie
[13:45:55] <djdelorie> Sync: I wrote the gcc backend for them so really got to know them. They have some advantages over other chips, that appeal to me
[13:46:17] <djdelorie> like wide range of vcc and EMI protection to the point of being nearly indestructable
[13:46:33] <djdelorie> plus the bootloader API is (1) public and (2) trivial to write software for
[13:47:17] <djdelorie> the internal peripherals are easy to understand and pretty powerful. The RX are peripheral-heavy too (my 2nd favorite mcu)
[13:48:44] <Sync> I always either did stuff with avrs, 8051s or stms
[13:49:10] <djdelorie> if the chips do what you want and you understand the tools, why change? ;-)
[13:51:30] <Sync> why not
[13:57:00] <unfy> because that's time spent learning new tooling rather than creating new widgets
[13:57:46] <unfy> for instance, i've got 8051 & avr experience. i generally won't go elsewhere for my uC needs
[13:58:59] <Loetmichel> unfy: i have to maintain some 851 code... i HATE it.
[13:59:03] <Loetmichel> 8051
[13:59:07] <Loetmichel> assembler
[13:59:37] <Loetmichel> and ages old, the Original programmer is retired and said code has next to no comments...
[14:03:21] <unfy> 8051 is nasty, i hate ti too
[14:03:26] <unfy> but its whats' used at work
[14:07:00] <Loetmichel> i like z80 assembler. but sadly there are not that much µcs based on that ;)
[14:08:18] <unfy> we're using primarily 89c2051's ... 128 bytes of ram and 2k of rom just... yeah. i hate the damn things
[14:08:56] <unfy> i think the latest thing i maintained on it has maybe 2 bits of the bit addressable memory free, and maybe 2-6 bytes of rom. sigh
[14:10:19] <FinboySlick> I'm playing with bpf 'assembler' for some networking stuff, it's surprisingly fun.
[14:14:29] <djdelorie> Loetmichel: look at the RL78 - it's basically an extended Z80
[14:18:23] <Loetmichel> unfy: i have to use ADUC8** at the company---
[14:18:53] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8833&g2_imageViewsIndex=1
[14:19:38] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8836&g2_imageViewsIndex=1 <-mlilitary tech... "fun" to repair. the PCB is riveted to the back of the Aluminium enclosure...
[14:19:53] <Loetmichel> had to repair it INSIDE there...
[14:20:24] <unfy> 8051's with bolt on stuff (or other way around, stuff with 8051 bolted onto it) ... grrr ._.
[14:20:47] <Loetmichel> yes
[14:21:44] <Loetmichel> ... no way to get it out without destroying it.
[14:21:52] <Loetmichel> and we had no spare anymore...
[14:22:01] <Loetmichel> so i repaired the traces... ;)
[14:23:31] <Polymorphism> sounds like fun xDD
[14:24:01] <Polymorphism> found some more options in addition to those enumerated in my forum post https://www.finelineautomation.com/products/complete-2-x3-router-kit?taxon_id=2 yet another option and also http://www.visionengravers.com/products/cnc-routers/2525-cnc-router-engraver-machine.php and also https://www.inventables.com/technologies/x-carve

[14:28:43] <Polymorphism> some people replied to my thread
[14:28:52] <Polymorphism> it's just about time to wrap this up
[14:28:56] <Polymorphism> finalize this decision
[14:31:20] <mase-tech> anybody know a program to calculate bending of a metal pipe tubing
[14:31:34] <mase-tech> free
[14:31:41] <Polymorphism> solidworks
[14:31:44] <mase-tech> free
[14:39:52] <Polymorphism> I need a cnc
[14:40:06] <mase-tech> build onme
[14:40:10] <mase-tech> easy peasy
[14:40:12] <djdelorie> you needed a cnc a month ago...
[14:41:18] <Polymorphism> djdelorie, that's true.
[14:41:40] <gregcnc> you could have had one a month ago
[14:41:43] <djdelorie> mase-tech: I'm holding down my end of the "easy-peasy" bell curve :-)
[14:41:58] <djdelorie> you get to figure out which end :-)
[14:42:00] <Polymorphism> could I really have though? I'm still not sure which one to get
[14:42:11] <Polymorphism> I'm hoping some replies to my thread clear this up
[14:42:28] <Polymorphism> it sounds like raptor, but I'm afraid of putting it all togetehr, the electronics especially
[14:42:32] <gregcnc> yes pick the first one you saw, learn rinse repeat. pretty much how the process goes, youre' just dragging it out
[14:42:33] <Polymorphism> a nice looking enclosure
[14:42:42] <Polymorphism> is that how you shop?
[14:42:43] <djdelorie> yes, most of the ones you worried over are good enough for what you want as long as the part physically fits.
[14:43:01] <djdelorie> You're worrying over stats that you either don't need or won't use yet
[14:43:18] <djdelorie> and a lot of the parts can be migrated to a better unit later
[14:43:30] <gregcnc> I look at features, good solid rails and frame for what you want is key, the rest is details
[14:44:09] <gregcnc> turns out control sucks, replace it, spindle? replace it, etc
[14:44:12] <mase-tech> Polymorphism: U said u are able to pay 4000$
[14:44:14] <Polymorphism> http://www.cncrouterparts.com/benchtop-standard-cnc-machine-kit-p-369.html
[14:44:17] <mase-tech> where is your problem
[14:44:20] <Polymorphism> mase-tech, up to, but I'd liket o spend less
[14:44:23] <djdelorie> mase-tech: he started at $5000
[14:44:26] <Polymorphism> I dont want to just sdpend the max, if the other machine will work
[14:44:37] <Polymorphism> djdelorie, tools, dust control, enclosure, stand, etc added up
[14:44:40] <Polymorphism> I had to adjust budget
[14:44:44] <mase-tech> My either
[14:44:47] <Polymorphism> what do you think of that cnc router parts?
[14:44:52] <djdelorie> spend about half your budget on the machine, and the other half on accessories as you find the need for them
[14:44:54] <Polymorphism> I heard it might be a good alternative to ratpro
[14:45:02] <mase-tech> I don t want to spend money. I want a fucking good machine for free
[14:45:05] <Polymorphism> djdelorie, thats why I changed my budget lower
[14:45:10] <mase-tech> Plz donate for my cnc
[14:45:23] <djdelorie> mase-tech: that was my route, but free turns out to be expensive :-)
[14:45:53] <djdelorie> yeah, but "about" is not precise. You're trying too hard, anything in the $2000-$4000 range is "about half"
[14:45:58] <mase-tech> I mean maxcnc gave u everything
[14:46:13] <mase-tech> I will build a concrete
[14:46:15] <mase-tech> cnc
[14:46:18] <mase-tech> later on
[14:46:33] <mase-tech> this cnc will be a mean machine cnc
[14:46:53] <mase-tech> now I am paing money for learning
[14:47:25] <djdelorie> I built my first cnc *knowing* that its purpose in life was to teach me how to build the 2nd one...
[14:47:40] <djdelorie> (or at least, how *not* to build it ;)
[14:47:41] <mase-tech> right
[14:48:09] <mase-tech> You cannt have the perfect machine for you right away because you don t know what the best machine is
[14:48:21] <Polymorphism> I will find out
[14:48:22] <Polymorphism> I'm so close
[14:48:42] <djdelorie> you were close enough a month ago. Now you're just putting off spending $$$
[14:48:43] <mase-tech> when you a ready tell me
[14:49:01] <djdelorie> as my wife often tells me, "buy something already!"
[14:49:13] <Polymorphism> well I posted the list
[14:49:17] <Polymorphism> I need to determine which machine wins
[14:49:28] <mase-tech> omg
[14:49:30] <Polymorphism> my use is listed clearly
[14:49:33] <Polymorphism> the machines are listed
[14:49:40] <Polymorphism> all I need is some people to tell me which machine will work for me
[14:49:43] <Polymorphism> for the least money
[14:49:44] <Polymorphism> thats it
[14:49:48] <Polymorphism> then I'm done
[14:49:58] <Polymorphism> I have my software planned
[14:50:01] <Polymorphism> I will make chips then
[14:50:07] <Polymorphism> I can't wait
[14:50:11] <Polymorphism> I want to make chips soon
[14:50:13] <mase-tech> but what if the people recommand the wrong machine
[14:50:16] <djdelorie> obviously you *can* wait
[14:50:18] <mase-tech> u will be angry
[14:50:22] <Polymorphism> thats why I will watch for some people ion agreement
[14:50:24] <Polymorphism> about a machine
[14:50:36] <Polymorphism> then I will know "this is the one"
[14:50:44] <Polymorphism> thats looking like raptor
[14:50:45] <Polymorphism> BUT
[14:50:47] <gregcnc> you won't get that
[14:50:50] <Polymorphism> I dont know if I can put it together
[14:50:56] <Polymorphism> the electronics into an enclosure
[14:51:02] <Polymorphism> and wire it up
[14:51:14] <Polymorphism> and I don't know if 12"x is too narrow
[14:51:16] <Polymorphism> and I'll regret it
[14:51:24] <Polymorphism> the other machines in the list have a lot more
[14:51:27] <Polymorphism> http://www.cnczone.com/forums/commercial-cnc-wood-routers/306666-cnc-manufacturing-software.html
[14:51:34] <Polymorphism> the list ^
[14:51:36] <Polymorphism> at bottom of post
[14:51:45] <Polymorphism> of my final choices, plus xcarve and the visioncarving machine
[14:52:56] <mase-tech> go for 6040
[14:53:01] <mase-tech> It is not that bad
[14:53:08] <Polymorphism> the Z kind of sucks
[14:53:09] <mase-tech> A friend of mine have one
[14:53:11] <Polymorphism> thats what holds me back from that
[14:53:14] <Polymorphism> I'll tell you all
[14:53:17] <Polymorphism> I would jhave bought the 6040
[14:53:18] <Polymorphism> the first day
[14:53:21] <Polymorphism> if it had more than 2.6"
[14:53:25] <Polymorphism> but I cant put my box inside that
[14:53:28] <Polymorphism> and mill the top
[14:53:32] <Polymorphism> I would have to use only split body
[14:53:36] <Polymorphism> that 2.6" z travel
[14:53:46] <gregcnc> cross it of the list, one less to consider
[14:53:59] <Polymorphism> 4" max part height
[14:54:04] <Polymorphism> yeah I pretty much have
[14:54:08] <Polymorphism> I think that would be limiting
[14:54:09] <Polymorphism> so the problem is
[14:54:11] <Polymorphism> because of that
[14:54:13] <Polymorphism> THAT put me up to 2500
[14:54:16] <Polymorphism> instead of 1400
[14:54:24] <Polymorphism> which broguth all these other options into play
[14:54:28] <Polymorphism> and made the decision difficult
[14:54:38] <gregcnc> i thought this machine is going to earn it's room and board
[14:54:38] <Polymorphism> then right as I was going to go with turn key omio x6-2200l
[14:54:46] <Polymorphism> someone said they stopped responding to their emails - pre sale
[14:54:59] <Polymorphism> it will but not for some time
[14:55:09] <Polymorphism> and only if it can do what I need it to
[14:55:10] <djdelorie> 2500 is still on the low end of "about half"
[14:55:40] <Polymorphism> I dont expect I will need much for tooling or software or dust / enclosure
[14:55:54] <Polymorphism> dust / enclosure I can do for a few hundred, and tooling a hundred more, I dont need much for my uses
[14:55:59] <Polymorphism> softwware free to 300
[14:56:10] <Polymorphism> 500 + 300 + 200 lets say
[14:56:11] <gregcnc> buying a machine tht's inexpensive, but incapable seems like a bigger mistake than spending too much on a good machine
[14:56:12] <Polymorphism> 1000 more
[14:56:19] <Polymorphism> so $3500 total would be nice
[14:56:29] <Polymorphism> gregcnc, I agree there 100%
[14:56:36] <Polymorphism> thats why this has taken me so long
[14:56:39] <Polymorphism> I really hate junk
[14:56:43] <Polymorphism> I hate crappy products
[14:56:50] <Polymorphism> they bother me
[14:56:51] <Polymorphism> I cant use them
[14:56:55] <djdelorie> either buy the cheapest you can, or the best you can - so either you don't mind replacing it, or you won't have to.
[14:57:00] <Polymorphism> I don't like when I put a lot of effort and time into something
[14:57:04] <Polymorphism> and it comes out sloppy because of the tool
[14:57:08] <Polymorphism> thats what I'm trying to avoid
[14:57:16] <Polymorphism> djdelorie, thats what my grandpa used to tell me
[14:58:05] <Polymorphism> I can't see what makes the raptor or cncrouterparts better than the omio x6-2200l
[14:58:08] <Polymorphism> and they each cost 500 more...
[14:58:17] <Polymorphism> they are also each larger than the raptor mini
[14:58:24] <Polymorphism> its really coming down to those three now
[14:58:36] <Polymorphism> 1. raptor mini 12x30x4 $3000
[14:58:52] <gregcnc> if omio is not repsonding remove it from the list
[14:58:55] <Polymorphism> 2. cnc routerparts desktop mini 25x25x6 $3000
[14:59:23] <Polymorphism> shapeoko3 has only 3" z clearance
[14:59:26] <Polymorphism> cross that off the list I guess
[14:59:51] <Polymorphism> 14x21x5.5" omio x6-2200l $2500
[14:59:54] <Polymorphism> but yeah... from china
[14:59:56] <Polymorphism> and not responding
[14:59:57] <Polymorphism> that kind of sucks
[15:00:20] <Polymorphism> both the cncrouterparts desktop mini and the raptorcnc require assembly of an enclosure and wiring for the electronics
[15:00:30] <Polymorphism> unless I purchase a separate kit from probotix
[15:00:43] <Polymorphism> premade I mean
[15:00:44] <Polymorphism> from them
[15:00:57] <Polymorphism> someone said the rails or bearings on the cncrouterparts wernt good
[15:01:02] <Polymorphism> is that speculation though?
[15:01:06] <gregcnc> no
[15:01:10] <Polymorphism> http://www.cncrouterparts.com/benchtop-standard-cnc-machine-kit-p-369.html
[15:01:18] <Polymorphism> what do you thinkl of that machine?
[15:01:25] <Polymorphism> someone on the forum said it was close to raptor maybe
[15:01:33] <Polymorphism> it does have a larger work area
[15:01:35] <Polymorphism> in all axes
[15:02:04] <Polymorphism> http://www.cncrouterparts.com/3-axis-diy-nema-23-electronics-kit-p-74.html
[15:02:08] <Polymorphism> thats the kit it comes with for electronics
[15:02:31] <Polymorphism> g540, 48v 420oz nmea 23s
[15:02:37] <Polymorphism> pre-wired with connectgors
[15:02:41] <Polymorphism> but would need a housing for that
[15:02:47] <Polymorphism> and my spindle + vfd I would by from china
[15:02:54] <Polymorphism> but how does the frame and rail system look
[15:02:56] <Polymorphism> is it a nice machine?
[15:03:02] <Polymorphism> because I like the price, I like american made
[15:03:05] <Polymorphism> I like the work area
[15:03:09] <gregcnc> i said raptor a month ago
[15:03:18] <Polymorphism> raptor only 12" x though....
[15:03:32] <Polymorphism> and to go to next size up 24" is $4000
[15:03:41] <Polymorphism> I'm worried I'll regret that small x
[15:03:43] * djdelorie imagines bolting a delta cnc to the ceiling of my shop - a tool that puts itself away!
[15:04:40] <gregcnc> where does the table go?
[15:04:54] <djdelorie> on the floor, wherever I feel like putting it. Homing will be critical...
[15:05:19] <Polymorphism> https://www.youtube.com/watch?v=NWZamlbTQhY
[15:05:57] <Polymorphism> does it look nice?
[15:06:19] <gregcnc> the red paint is nice
[15:06:25] <Polymorphism> this is the perfect size
[15:06:29] <Polymorphism> for my needs
[15:06:36] <Polymorphism> the raptor is an odd size and maybe small...
[15:06:38] <Polymorphism> I know its very nice
[15:06:40] <Polymorphism> probably best built
[15:06:41] <Polymorphism> but
[15:06:44] <Polymorphism> 12x30"
[15:06:45] <Polymorphism> is odd
[15:06:50] <Polymorphism> this is 25x25x6"
[15:06:56] <Polymorphism> more z and more square
[15:06:59] <Polymorphism> better for my enclosures
[15:07:08] <Polymorphism> and I can fit a guitar body
[15:07:12] <Polymorphism> if it could handle 3d carve hardwood
[15:07:20] <Polymorphism> I really like this option
[15:07:22] <Polymorphism> but the bearings...
[15:07:25] <Polymorphism> someone said they are bad?
[15:07:28] <Polymorphism> but are they just speculating
[15:07:38] <djdelorie> these are the same questions you had a month ago
[15:07:46] <Polymorphism> are they?
[15:07:55] <gregcnc> the problem here is that after a month you still don't understand basic machine design elements
[15:07:55] <djdelorie> if you don't have an answer yet, you'll never have one
[15:08:08] <Polymorphism> but I do
[15:08:15] <Polymorphism> to some extent
[15:08:22] <gregcnc> then linear rails is the onyl answer if you intened to touch metal
[15:08:23] <Polymorphism> that still doesnt tell me how this machine looks to experienced users
[15:08:39] <Polymorphism> gregcnc, but that statement... what I've found is I'm not sure it's true???
[15:08:51] <Polymorphism> even shapeko3 machine claims to cut aluminum and I see the videos, and the result
[15:08:53] <djdelorie> gregcnc: my machine uses linear rails, and I'm still scared to mill metal with it
[15:09:02] <Polymorphism> and for me, I only need to cut 2mm aluminum
[15:09:09] <Polymorphism> I dont need to make big solid parts
[15:09:15] <Polymorphism> I just need to route sheet metal, basically
[15:09:18] <gregcnc> all the aluminum cutting I've seen in routers, any of them looks like crap
[15:09:45] <Polymorphism> http://www.cnczone.com/forums/commercial-cnc-wood-routers/285078-cnc.html
[15:09:49] <gregcnc> preloaded
[15:09:50] <Polymorphism> that was all cut on mini raptor
[15:09:50] <djdelorie> and my cutter sled wobbles all over the place ;-)
[15:09:53] <Polymorphism> does it look crap ?
[15:09:59] <Polymorphism> I'm serious, I don't know what to look for
[15:10:02] <Polymorphism> to me, it looked nice
[15:10:07] <Polymorphism> and all I need to do
[15:10:11] <Polymorphism> is cut a hole for a component to go into
[15:10:14] <Polymorphism> that will then overlap
[15:10:22] <Polymorphism> and I need to engrave just accurate enough
[15:10:25] <Polymorphism> so it can be read easily
[15:10:29] <Polymorphism> and look professional
[15:10:38] <Polymorphism> I dont need to make components for race cars or anything
[15:10:39] <djdelorie> you've just described what lasers are used for
[15:10:42] <Polymorphism> nothing with that type of precision
[15:10:51] <gregcnc> those parts have been finished, but if they are off the raptor they aren't bad at all and i'm not surprised
[15:11:03] <Polymorphism> djdelorie, found no laser affordable capable of cutting 2-4mm aluminum
[15:11:17] <djdelorie> well, yeah, "affordable"
[15:11:35] <Polymorphism> an order of magnitude above my budget
[15:12:11] <Polymorphism> I'm just worried gregcnc what you're telling me applies to metal parts
[15:12:13] <Polymorphism> not metal routing
[15:12:19] <Polymorphism> I'm routing, not milling
[15:12:35] <Polymorphism> I don't want to spend more than I need, when I won't be milling
[15:12:38] <Polymorphism> and if I mill, its wood
[15:14:43] <Polymorphism> https://www.youtube.com/watch?v=cZ_Jy6WpYfQ
[15:14:45] <Polymorphism> this machine though
[15:14:49] <Polymorphism> it doesnt look as nice as raptor...
[15:14:56] <Polymorphism> looks thinner gantry sides
[15:15:04] <Polymorphism> those rollers
[15:15:20] <Polymorphism> https://www.youtube.com/watch?v=cZ_Jy6WpYfQ
[15:15:41] <Polymorphism> but what do I know
[15:16:24] <Polymorphism> https://www.youtube.com/watch?v=hwblYO0vtHM
[15:16:33] <Polymorphism> they also have a "pro" model they shjow cutting aluminum parts
[15:18:03] <Polymorphism> maybe they are nice machines?
[15:23:03] <djdelorie> by this time next year, you'll have bought one of each, and put up a website comparing them... ;-)
[15:23:34] <gregcnc> i was going to suggest just that, maybe make some moeny that way
[15:23:49] <mase-tech> Hey peps
[15:23:58] <gregcnc> yo dog
[15:24:07] <mase-tech> I must tell u something about germany
[15:24:17] <djdelorie> must?
[15:24:21] <mase-tech> yes
[15:24:47] <mase-tech> I germany there are people how make races
[15:25:21] <mase-tech> with cars on normal street
[15:26:06] <mase-tech> A accident happend in this race and a woman by bike was caught by a cars
[15:26:35] <mase-tech> She flyed more than 50 meters and dies
[15:27:37] <mase-tech> Today our JUSTICE spoke the judgment
[15:28:07] <mase-tech> 2 1/2 your on PAROLE (no prision)
[15:28:56] <Polymorphism> thsats excellent news!
[15:29:09] <SpeedEvil> Depending on the situation, that could be an appropriate sentance.
[15:29:16] <mase-tech> Germany the best country in the world
[15:29:29] <Polymorphism> and humble too =D
[15:29:34] <mase-tech> Not able to make justice
[15:29:44] <SpeedEvil> If the race was not adequately placarded, then people racing bikes are going significantly faster than you'd normallly expect bike riders to go.
[15:29:45] <Polymorphism> sounds like good justice to me
[15:30:11] <mase-tech> On official street
[15:30:29] <Polymorphism> I just emailed george from xzero cnc about the raptor mini clearance
[15:30:32] <Polymorphism> he responded in 4 minutes
[15:30:34] <mase-tech> no track no race street
[15:30:36] <Polymorphism> that has to be worth something
[15:30:40] <gregcnc> illegal street race or organized?
[15:30:48] <mase-tech> ILLEGAL
[15:31:17] <djdelorie> were the bikes racing, or the cars?
[15:31:20] <SpeedEvil> Oh
[15:31:30] <djdelorie> i.e. was the victim one of the illegal racers, or a bystander?
[15:31:33] <mase-tech> Is my englsih so bad
[15:31:35] <mase-tech> omg
[15:31:45] <Polymorphism> mase, what happened to the bike?
[15:31:47] <Polymorphism> they stole it?
[15:31:49] <djdelorie> english is sometimes too subtle
[15:32:19] <mase-tech> The woman was on the way to friends
[15:32:26] <mase-tech> no bystander
[15:32:28] <djdelorie> like the difference between "Let's eat, grandma!" and "Let's eat grandma!"
[15:32:32] <mase-tech> the race was illegal
[15:32:34] <gregcnc> illegal street racer kills innocent cyclist
[15:32:48] <XXCoder> mase-tech: so guy who killed that lady gets 2 years and half?
[15:33:06] <mase-tech> yes on parole with no prision
[15:33:21] <djdelorie> around here we're more likely to have bike races on streets, where the cars are the innocent bystanders
[15:34:00] <mase-tech> The judged has to stay clean for 2 1/2 year
[15:34:04] <gregcnc> a guy in the UK got that for two drifting laps around a round about with no one around.
[15:34:08] <Polymorphism> ohh so the street racing car driver killed the lady on a bike
[15:34:13] <Polymorphism> and he got 2 1/2 year probation
[15:34:16] <Polymorphism> that sounds fair
[15:34:34] <Polymorphism> bikes are always running red lights etc, she probably cut in front of him
[15:34:45] <Polymorphism> we need the full story
[15:34:47] <mase-tech> Are u drunk
[15:35:13] <djdelorie> or you could read "criminal car drivers murder innocent mother of three, get off with only probation" ;-)
[15:35:25] <Sync> it is not murder
[15:35:36] <unfy> it's man slaughter.
[15:35:38] <Sync> yep
[15:35:39] <djdelorie> yeah, need full story. As long as it has something to do with CNC of course :-)
[15:35:40] <XXCoder> even manslather here gets years of prison
[15:35:46] <unfy> jurisdictional legal distinction etc
[15:35:48] <djdelorie> Sync: depends on the full story, of course :-)
[15:36:08] <mase-tech> Somebody here with son
[15:36:11] <mase-tech> or daughter
[15:36:17] <Sync> djdelorie: they were racing, one of the cars lost control, spun out and killed her
[15:36:35] <Polymorphism> I don't think if she had children or not changes the crime
[15:36:44] <mase-tech> image if your kid would die tomorrow because a fucking morron kills her in a illegal car RACE
[15:36:45] <djdelorie> but... maybe they intentionally spun out when they saw here there! It could happen! (sarcasm ;)
[15:37:00] <djdelorie> Poly: of course not, it just changes how people feel about the headlines.
[15:37:01] <Sync> mase-tech: it doesn't change anything
[15:37:17] <Sync> it won't bring it back if the person is on probation or not
[15:37:20] <Sync> or in jail
[15:37:26] <mase-tech> but that is not engough ........ HE GETS 2 1/2 year probation
[15:37:31] <djdelorie> mase-tech: my daughter's been rear-ended three times by "more experienced drivers" who just weren't paying attention
[15:37:51] <djdelorie> mase-tech: you mean "he gets ONLY 2 1/2 years" ?
[15:37:55] <mase-tech> this morrorn deserves death
[15:37:58] <Sync> no
[15:38:02] <Sync> it happens
[15:38:10] <XXCoder> and zero prison time
[15:38:21] <Polymorphism> how does his death bring the woman back
[15:38:25] <Sync> if your daugther dies of a heart attack just now
[15:38:30] <Sync> who are you going to blame?
[15:38:34] <XXCoder> Polymorphism: who called for his death?
[15:38:40] <Polymorphism> mase-tech, did, just now
[15:38:40] <Sync> does god need to go to prison?
[15:38:45] <mase-tech> I call it
[15:38:48] <mase-tech> I do
[15:38:58] <gregcnc> are they allowed to drive?
[15:39:06] <Sync> no
[15:39:11] <Sync> they can reapply for their license in 3 years
[15:39:20] <XXCoder> Sync: not remotely same
[15:39:42] <XXCoder> its different if guy was driving cleanly and acciently hit
[15:39:44] <mase-tech> They were driving a race in the city
[15:39:48] <XXCoder> but guy was illegally racing
[15:40:13] <djdelorie> there's a huge range between "accidents happen" and "planned murder", the courts have to decide where each case is on that range and punish accordingly
[15:40:26] <XXCoder> djdelorie: never said planned murder either
[15:40:43] <djdelorie> I know, but that's one of the endpoints on that continuum
[15:40:47] <XXCoder> its manslather which carries pretty serious charges in usa, expecially if it was assocated to something illegal
[15:41:04] <mase-tech> Zero prision time for a woman killed in an illgal race
[15:41:13] <XXCoder> not as serious as actual planned murder but still
[15:41:33] <Polymorphism> mase-tech, was the woman obeying all traffic laws
[15:41:39] <mase-tech> Yes
[15:41:44] <djdelorie> heck, even copying mp3s carries a stiffer sentence than that ;-)
[15:41:47] <Sync> XXCoder: then he would not even receive a sentence, most probably
[15:42:47] <mase-tech> I wish texan law for him
[15:42:52] <mase-tech> kill
[15:42:55] <mase-tech> over and out
[15:42:59] <Sync> why?
[15:43:18] <XXCoder> I dont wish death either, I rarely do so
[15:43:23] <XXCoder> just actual prison time
[15:43:29] <mase-tech> For taking a life for sillyness he lost his right
[15:43:44] <XXCoder> 2.5 years actual prison time is better than just free basically
[15:44:02] <mase-tech> I would be ok with 25 years
[15:44:09] <Loetmichel> mase-tech: NOBODY "deserves" Death
[15:44:14] <mase-tech> by the way the man is 22
[15:44:26] <XXCoder> manslather 25 years quite mucj
[15:45:02] <mase-tech> I am mad
[15:45:21] <Polymorphism> channel your anger into deciding which cnc I need
[15:45:26] <Loetmichel> and especially not for an involuntary act of losing control.
[15:45:45] <XXCoder> http://criminal.findlaw.com/criminal-charges/involuntary-manslaughter-penalties-and-sentencing.html
[15:45:48] <Loetmichel> it was an illegal race, right. but it still was an accident, the didnt intend to kill her
[15:46:24] <XXCoder> in calfornia guy got 2 years after acciently using gun and not stun gun
[15:46:25] <Loetmichel> so he can only be sentenced for "reckless driving". Not for murder
[15:46:28] <mase-tech> Yes... and the judgement is ok for you ?
[15:46:31] <Polymorphism> this was a carmageddon style race though, running over pedestrians increased score
[15:46:37] <Polymorphism> so perhaps his sentence WAS too light
[15:46:41] <zeeshan|2> if it was your sister/mom
[15:46:44] <mase-tech> He took a life !
[15:46:45] <zeeshan|2> you'd think a lot differently :P
[15:47:18] <Sync> zeeshan|2: I would not
[15:47:28] <zeeshan|2> must hate them then
[15:47:28] <zeeshan|2> :P
[15:47:29] <XXCoder> weird
[15:47:30] <Sync> it's just another person, after all
[15:47:36] <mase-tech> He took a life and get away with zero prision time
[15:47:37] <XXCoder> I cant find similiar law in germany
[15:47:40] <XXCoder> results is all murder
[15:48:00] <unfy> willful negligence might be considered murder over there, etc
[15:48:03] <Loetmichel> mase-tech: yes, he took a life, and if you want to take his you are no iota better than him. PERIOD
[15:48:30] <unfy> which is why we have different jurisdictions / countries / laws-that-fit-a-given-society etc
[15:48:40] <XXCoder> ah found it
[15:48:41] <XXCoder> Section 213 - Less Serious Case of Manslaughter
[15:48:41] <XXCoder> If the person committing manslaughter was provoked to rage by maltreatment inflicted on him or a relative or a serious insult by the person killed and was thereby immediately torn to commit the act, or in the event of an otherwise less serious case, the punishment shall be imprisonment from one year to ten years.[9]
[15:50:30] <XXCoder> wow microsoft made DNA data storage, one billion TB a gram
[15:50:31] <mase-tech> He killed a innocent woman
[15:50:31] <Loetmichel> and if it were my sister that died there i would mourn her. But i think the boy that did that will have to carry enough on his consience now. even without a prison sentence at all. At lest its sounds like the judges were convinced of that.
[15:51:02] <Loetmichel> XXCoder: but 1.5 metric tons for the drive?
[15:51:13] <mase-tech> I am not convinced of the judges
[15:51:14] <XXCoder> it doesnt say
[15:51:20] <mase-tech> I my eyes it is a fault
[15:51:31] <gregcnc> or they expect to be seeing him again within 2.5 years
[15:51:57] <mase-tech> In
[15:53:40] <unfy> just to add some fun -- and to think, the punishment for downloading a torrent is much harsher :D
[15:54:13] <mase-tech> The result matters for me more than the circumstances
[15:55:05] <mase-tech> It is almost like the asian boy killed by a group of muslims
[15:55:17] <mase-tech> but I will not go into that
[15:57:05] <XXCoder> Loetmichel: honestly 1.5 metric ton 1 billion tb drive may be worth it anyway lol
[15:57:08] <XXCoder> for some uses
[15:58:12] <Loetmichel> XXCoder: depends on r/w speed ;)
[15:58:17] <XXCoder> indeed.
[15:58:27] <XXCoder> if nothing else it'd be great for arcive
[15:58:27] <unfy> see, i'm reminded of things like.... pc mag or something. they had a bunch of archives. but they were all half missing. it took a grey beard to point out they needed to eject the mimo drives and flip them over to read the other side of the discs.
[15:58:50] <Loetmichel> HIHI
[15:58:52] <unfy> so, in X years, I can see "we have this 1 gram data storage cube. but no one knows how to read it"
[15:59:08] <XXCoder> unfy: format loss is always possible
[15:59:10] * Loetmichel still has some of his Amiga backups on paper
[15:59:34] <XXCoder> VERY few has umm 9"? floppy drive, NASA keep buying em at ebay'
[15:59:40] <Loetmichel> "letter" sized "qr-codes" ;)
[16:00:07] <mase-tech> haa
[16:00:18] <Loetmichel> XXCoder: i have an 8" drive and a bunch of 8" SS-SD foppies in the cellar. they still work
[16:00:28] <XXCoder> Loetmichel: watch out for NASA
[16:00:46] <unfy> in the late 90's i grabbed a cd burner. i immediately got rid of all floppies.
[16:00:54] <Loetmichel> ... and a z80 based "personal computer" that can use them ;)
[16:00:57] <unfy> sadly, bit rot was still a thing ._.
[16:01:16] <XXCoder> unfy: yeah I have a ZIP disk thats probably corrupt
[16:01:35] <XXCoder> click of death killed support for it
[16:01:35] <mase-tech> I have a old C64
[16:01:43] <unfy> i've been eyeballing the archival discs. they're tempting.
[16:01:47] <mase-tech> maybe I could turn him on
[16:01:52] <Loetmichel> unfy: i stil have about 1800 Amiga 3,5" floppies... and about 2k C64 5,25" disks
[16:02:00] <Loetmichel> ... no idea if they still work tho
[16:02:10] <XXCoder> Loetmichel: good chance no
[16:02:19] <neckro23> for long-term storage you gotta go low-tech: http://group47.com/what-is-dots/
[16:02:21] <XXCoder> data lasts around 2 to 5 years depending on storage
[16:02:23] <Loetmichel> the 3 c64 that are in my cellar has not been run a decade or so
[16:02:38] <Loetmichel> XXCoder: depends on density
[16:02:38] <unfy> in my experience, the media tends to be okay - the device to access the media is what sucks
[16:02:44] <XXCoder> neckro23: or very high tech. theres new cd tech that can hold data for very long time
[16:02:48] <Loetmichel> some old DD flopies are still readable
[16:02:53] <XXCoder> nice
[16:03:11] <XXCoder> neckro23: http://www.cnet.com/news/a-360tb-disc-that-holds-data-for-more-than-1-million-years/
[16:03:35] <XXCoder> fused quartz, last very long time'
[16:03:49] <neckro23> yeah but does the reader last 1 million years
[16:04:04] <XXCoder> just make sure there is specs in durable media too
[16:04:13] <unfy> the m-disc stuff is what i was thinking of
[16:04:19] <Loetmichel> neckro23: the usual diode laser has a lifetime of less than a few 1000 hours.
[16:04:24] <unfy> a bit pricey, but ... supposed to be decent.
[16:04:27] <Loetmichel> i dont think so ;)
[16:04:39] <unfy> of course, with how long NES and other cards last, eeprom is clearly the way to go :D
[16:04:47] <unfy> carts, even
[16:05:33] <Loetmichel> unfy: ahem... there are books from about 2000bc that are still in pristine condition
[16:06:21] <Loetmichel> i think there ARE ways to store data for long times that dont include magnetic or phase change techniqes
[16:06:38] <XXCoder> properly prepured paper in protected envorment last basically forever
[16:06:46] <XXCoder> acid-free paper
[16:06:47] <unfy> loet: and theres' always the fire at alexander's library.
[16:07:06] <Loetmichel> one can imagine a continous QRcode printed by steel needles on a 2" wide stainless steel foil tape
[16:07:09] <unfy> buuuuuutttttt.... what i wanna archive isn't anything that's pen & paper friendly etc.
[16:07:18] <Loetmichel> should outlive any human by a few centuries
[16:07:38] <neckro23> qr codes tattooed on a mummy's skin
[16:08:08] <unfy> or the skin of a cat. .... cat data. rolls eyes :P
[16:08:12] <membiblio> Has anyone tried to *install* LinuxCNC 2.7? (vs running live dvd) Did your desktop come up with xfce4-panel or not? Is this a known issue?
[16:08:38] <Loetmichel> also a properly maintained "writer" of that steel foil tape would live quite a few centuries of continous operation
[16:08:41] <unfy> mem: last time i tried to install linux cnc 2.7, it was on a machine with bad ram sticks. so it got nowhere ._.
[16:09:36] <Lowridah> membiblio: can't fill the dep?
[16:09:38] <membiblio> thanks unfy - if you try again please see if your 'desktop' has a 'taskbar' with clock, etc on it. I do not believe it will.
[16:10:02] <membiblio> Lowridah - I don't know what you mean. Do you?
[16:10:06] <Deejay> gn8
[16:10:08] <Lowridah> sudo apt-get install xfce4-panel
[16:10:12] <Lowridah> is what i mean?
[16:10:23] <unfy> nite deejay o/
[16:10:24] <Lowridah> or yum -y install xfce4*
[16:10:24] <membiblio> Lowridah - again - have you *seen* this issue?
[16:10:32] <Lowridah> no
[16:10:44] <Lowridah> i was hoping to get you past it but i'll just ignore
[16:11:18] <membiblio> Lowridah - because if you *paid attention* I previously said that xfce4-panel is installed and I have already fixed it on my installation. My inquiry was to determine if this is a known issue.
[16:11:41] <Lowridah> wow sorry for trying to help without reading pages and pages of backscroll
[16:11:50] <membiblio> Lowridah - thank you - but that will not work as apt will just report back *already installed* :)
[16:12:03] <membiblio> Lowridah - it is ok
[16:12:54] <membiblio> On another note - has anyone successfully offloaded step generation to a separate slave mcu? (And kept integration with LinuxCNC proper?)
[16:14:24] <Sync> the mesa cards do that
[16:14:57] <membiblio> Sync - do they do that by interpreting g-code or by sending step pulses across the udp ethernet?
[16:15:23] <membiblio> Sync - vs tcp eth which would have significant delay.
[16:15:47] <cradek> neither. linuxcnc sends a velocity command and the fpga sends back position in realtime on every update
[16:16:21] <cradek> microcontroller is the wrong tool for the job - all the external stepgens are based on fpgas, there are many
[16:16:36] <membiblio> cradek - that is interesting - is this a function of LinuxCNC and it's code base or a addition that mesa added to LinuxCNC?
[16:17:32] <membiblio> Cradek - actually modern mcu are exactly the right tool for the job :) They do it every day in motion control systems.
[16:17:38] <cradek> that scheme for external stepgens is older than mesa
[16:18:00] <membiblio> Cradek - thank you for your input. I will take it into consideration.
[16:19:15] <membiblio> cradek - have you installed lcnc 2.7?
[16:19:17] <PCW> MCUs will work but generally have inferior timing characteristics
[16:20:07] <PCW> (though will work for low cost/low performance)
[16:24:52] <PCW> Some newer micros have hardware DDS's which would remove some of the limitations, but normally only one or a couple of channels
[16:27:14] <neckro23> I've installed linuxcnc 2.7 without problems, I'm not sure what the resulting window manager was though
[16:27:36] <neckro23> I think I just installed debian wheezy and then added the linuxcnc ppas
[16:27:39] <membiblio> neckro23 - did you *install* or run the *livedvd* ?
[16:27:49] <neckro23> yeah installed installed
[16:27:51] <unfy> late last year, while doing thousands of insertions on a bill acceptor (casino industry) for testing purposes - i watched some youtube videos and such on fpga 'coding' etc. on the ground level it doesn't seem all that difficult
[16:27:57] <djdelorie> PCW: my cnc uses such an MCU, it's got enough hardware to run a BLDC motor, the mcu just tweaks the settings as needed
[16:28:11] <membiblio> neckro23 - that is different that installing the distribution .iso from the linuxcnc website. Thanks though.
[16:28:56] <djdelorie> unfy: fpga programming isn't difficult. Getting it right under tight constraints is.
[16:29:25] <unfy> so, i can totally see fpga/cpld stuff being perfect for step generation / closed loop stuff etc etc etc
[16:30:19] <unfy> and not requiring a lot of fpga horsepower. as cheap as an attiny ? possibly not. but still cheap for a smaller device etc
[16:31:16] <membiblio> unfy - on your topic - which fpga did you look at and what tool created it's 'personality'? fpga tools either take in schematic capture or vhdl - vhdl can be artistic - getting anything to fit within your targeted fpga takes effort - but today we have large devices but interface and cost is still a consideration.
[16:31:41] <unfy> hmmmm i was wanting to not do the schematic bit
[16:31:58] <unfy> and... i think i was looking at vhdl (and not verilog) ...
[16:32:00] <djdelorie> smallest FPGA on digikey is $1.25 but cost is proportional to how much stuff you're cramming into it
[16:32:11] <PCW> FPGA's have the advantage the you can tailor the hardware to exactly what you need, on a UC you will probably have to do step generation as an interrupt task
[16:32:13] <unfy> this means - prolly atmel's tools
[16:32:27] <unfy> (i think lattice is all verilog)
[16:32:40] <membiblio> unfy - if you go schematic capture - you have to use a capture tool who output is compatible with various device manufacturers 'compilers' - in the open source world this is a almost insurmountable feat
[16:32:59] <djdelorie> the advantage of MCUs is that the complex things are easy. The advantage of FPGAs is that the simple things are fast and predictable.
[16:33:05] <unfy> mem: indeed. and - i'd rather use text than pictograms anyway :D
[16:34:07] <unfy> i've sadly not bought a devkit for any of it yet -- been avoiding it in purpose. too many projects in flight at once as is. need to thin the herd a bit :D
[16:34:23] <djdelorie> wow - most expensive FPGA on digikey is $61294.80
[16:34:29] <PCW> djdelorie: Right (so in the FPGA we use embedded processors if the speed/complexity tradeoff is better in software)
[16:34:46] <unfy> on purpose ._. ...... since switching to colemak i've noticed a lot more typos in my irc typing ._.
[16:34:46] <djdelorie> PCW: embedded hardware processors, or soft processors?
[16:36:09] <djdelorie> PCW_: embedded hardware processors, or soft processors? (repeat)
[16:36:37] <PCW_> embedded soft processors
[16:37:20] <PCW_> many of the standard HM2 configs have multiple soft processors
[16:38:17] <djdelorie> which puts FPGAs just that much closer to MCUs with dedicated motor control peripherals :-)
[16:41:04] <pink_vampire> hi girls
[16:41:30] <membiblio> girls or ladies?
[16:41:40] <membiblio> pu lease
[16:42:38] <djdelorie> pink_vampire: was thinking about you today. Clipped my fingernails :-)
[16:42:47] <membiblio> Well there is a interesting thread on the mach3 website about this very topic re: offloading step generation
[16:42:53] <PCW> well the soft MCUs in HM2 are mainly used for various communication chores
[16:43:11] <pink_vampire> lol
[16:43:29] <pink_vampire> djdelorie: at least you think about me..
[16:43:34] <djdelorie> :-)
[16:44:49] <pink_vampire> maybe my nails a bit too long
[16:45:49] <djdelorie> PCW: in my case, the MCU does the PID math (floating point) and the hardware handles pwm (out) and rpm/position (quadrature encoders) etc.
[16:47:18] <djdelorie> so the clark-park stuff is in the MCU but the sw just has to update a few phase registers and read the new rpm/position/current results
[16:47:32] <djdelorie> then wait for the next timer interrupt ;-)
[16:48:07] <PCW> Right, for a single channel motor control a MCU is appropriate (unless you need to add a fancy encoder)
[16:48:18] <djdelorie> I have the fancy encoder
[16:48:31] <PCW> BISS, Fanuc?
[16:48:47] <membiblio> PWC why do you do floating point instead of integer or do you emulate or use a library?
[16:48:52] <djdelorie> the MCU has two quadrature inputs, I use one for the step/dir input (the register records "desired position") and the other for the motor's encoder ("actual position")
[16:49:54] <djdelorie> so the P term of that PID is literally the difference between the two hw registers
[16:54:08] <PCW> I just mentioned fancy encoders as that's one reason higher end drives use FPGA's (or ASICs)
[16:56:48] <PCW> also FPGA's are better at generating clean quadrature out for drive position feedback to the host
[16:56:50] <PCW> ( for the same reason that they can generate cleaner step/dir pulse streams than MCUs )
[17:32:09] <FinboySlick> zeeshan|2: You around?
[17:49:06] <alex4nder> PCW: hey,.. random question: I've got a 7i76E that's working with my 3 axis mill.. I'm thinking of adding a 4th axis, and doing via a BLDC+encoder
[17:49:31] <alex4nder> is that something I could pretty easily integrate into the 7i76E with the mesa BLDC driver board?
[18:05:41] <PCW> alex4nder: yes you could use the 7I76E RS-422 expansion port for a 8I20 though there are some limitations
[18:05:43] <PCW> ( 1 KHz update rate is pretty slow for commutation and you can only get to 2-4 KHz Ethernet which is better
[18:05:45] <PCW> with specific motherboards )
[18:06:09] <alex4nder> ok
[18:06:39] <Sync> PCW: which boards specifically? I've been on the lookout for one
[18:11:03] <JT-Shop> http://gnipsel.com/images/equipment-shed/big-dig-05.jpg
[18:11:15] <JT-Shop> http://gnipsel.com/images/equipment-shed/big-dig-06.jpg
[18:11:27] <JT-Shop> hope my pool doesn't fill up tonight
[18:11:31] <_methods> where's the dynamite
[18:11:42] <JT-Shop> kinda hard to get anymore
[18:11:46] <_methods> hahah
[18:12:06] <unfy> hateful rock and clay >_>
[18:12:08] <_methods> yeah those terrorists like blowin stuff up or something
[18:13:02] <JT-Shop> I guess this is good https://ibin.co/2foYLzSb98eC.png
[18:14:28] <alex4nder> PCW: is it reasonably possible I could do the commutation inside the FPGA, with some development work?
[18:16:19] <PCW> Yes but its probably not worth the trouble for a one-off
[18:17:27] <PCW> Sync: I can run our Ethernet FPGA cards with linuxcnc reliably at 4 KHz with the ASRock H97 PRO4
[18:18:19] <PCW> (reliably meaning I have more than a year of uptime at 4 KHz with no real time errors)
[18:18:34] <Sync> yeah that sounds ok
[18:19:08] <PCW> thats with a G3258 CPU
[18:19:34] <PCW> which is also pleasantly fast
[18:20:12] <pink_vampire> http://ustre.am/1qGHt
[18:20:21] <pink_vampire> slooooooow
[18:21:49] <Sync> yeah that sounds like a nice combination
[18:21:54] <Sync> although I'd have to add a second nic
[18:22:55] <pink_vampire> Sync: what do you mean?
[18:23:55] <Sync> read the backlog
[18:23:58] <Meduza> Can linuxcnc rotate a coordinate system around the Z axis?
[18:24:19] <Meduza> (without rewriting stuff, just out of the box)
[18:24:49] <JT-Shop> yes
[18:25:09] <Meduza> great, off to read the manual then :p
[18:25:12] <PCW> I use a USB/Ethernet dongle for non rt
[18:25:26] <JT-Shop> start with G10L2
[18:26:10] <Meduza> is it like G10 L2 P0 R90
[18:26:15] <Meduza> to turn it 90 degrees?
[18:27:16] <Meduza> "it" = the active coordinate system
[18:27:30] <JT-Shop> yup
[18:28:52] * JT-Shop swaps to his chef hat and heads inside to start some shrimp Étouffée
[18:32:31] <Meduza> "Being in incremental distance mode (G91) has no effect on G10 L2." <-- does this mean that you cannot rotate a coordinate system and move incrementally, or that it will work just as fine as if you were doing it as usual?
[18:36:46] <Meduza> JT-Shop: ^
[18:40:31] <cradek> G91 incremental motion works fine when the coordinate system is rotated. that sentense is saying that G91 has no effect on the G10 command itself.
[18:41:27] <Meduza> great, then i can probably write the subroutine as i want to :-)
[18:41:31] <cradek> sentence
[18:50:16] <Meduza> So, if i understand this right...
[18:51:16] <Meduza> http://pastebin.com/SAdZk4we
[18:51:49] <Meduza> should that code not make four short moves in four different directions?
[18:52:12] <Meduza> when i try it it makes four moves in different directions, but they are crazy long and super slow
[18:57:31] <cradek> I'm not sure - that's very weird code. what are you trying to do? maybe you want polar coordinates?
[18:59:01] <cradek> if you want to move 1 unit at 22 degrees you could directly program g91 g1 x[cos[22]] y[sin[22]]
[18:59:28] <cradek> rotating the coordinate system is really meant for setup (like mounting a vise rotated)
[19:00:09] <pink_vampire> mach 3 made unexpected move. and send Z axis to -57
[19:00:15] <pink_vampire> why??
[19:00:48] <pink_vampire> and I was in a line that talk about X.
[19:00:53] <pink_vampire> WTF
[19:01:20] <pink_vampire> how something like that happen.
[19:01:48] <cradek> you realize you won't get useful answers asking about mach3 in #linuxcnc, right?
[19:01:49] <pink_vampire> I I've run this code over and over again
[19:02:26] <malcom2073> Not even not getting useful answers: You realize you'll get *wrong* answers asking about mach3 in #linuxcnc?
[19:02:38] <malcom2073> Like, actually unintentionally misleading answer
[19:02:44] <pink_vampire> cradek: I'm wondering if something like that can happen in linux cnc
[19:02:47] <cradek> malcom2073: well just because they're snarky doesn't mean they're wrong
[19:02:52] <malcom2073> cradek: :-P
[19:03:02] <cradek> e.g.: what do you expect, you should be using linuxcnc
[19:03:04] <CaptHindsight> mach3 ate my baby
[19:03:16] <malcom2073> I was thinking more of: We tell you the "right" answer, but mach3 does things wrong, thus it is the wrong answer for you
[19:03:56] <pink_vampire> ok
[19:04:09] <pink_vampire> how do I start with linux cnc?
[19:04:15] <pink_vampire> what to download
[19:04:21] <pink_vampire> how to install
[19:04:29] <pink_vampire> who I need to pay
[19:04:51] <cradek> pink_vampire: go to linuxcnc.org, start reading the very clear answers to those questions
[19:05:29] <cradek> it's smart to save your questions here for the hard ones
[19:05:31] <pink_vampire> what is the most updated version of linuxcnc?
[19:05:45] <cradek> same advice
[19:06:01] <malcom2073> pink_vampire: If you're looking for hand-holding, mach3 is best for you
[19:06:25] <pink_vampire> but it crash the machine
[19:06:41] <pink_vampire> and it's not the first time
[19:07:18] <malcom2073> Don't you use servos?
[19:07:22] <malcom2073> What interface board are you using?
[19:07:26] <pink_vampire> I know there is a bug that open about that, and they don't know what to tell you other then buy the mach 4
[19:07:36] <pink_vampire> 2 lpt
[19:07:52] <pink_vampire> work fine for the feed rate that I need
[19:08:29] <malcom2073> Mach3 is significantly more lenient in terms of step rate out of a parallel port. You should load up linuxcnc livecd, run the latency test and se if it'll work for what you need
[19:09:14] <pink_vampire> link?
[19:09:37] <pink_vampire> http://linuxcnc.org/2016/02/08/release-2.7.4/
[19:09:42] <pink_vampire> this one?
[19:10:27] <pink_vampire> where is the download link??
[19:10:33] <pink_vampire> http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
[19:10:35] <malcom2073> Click "downloads" at the top.....
[19:10:38] <pink_vampire> this one??
[19:10:47] <pink_vampire> ok.. but but to download?
[19:10:47] <malcom2073> Yep
[19:11:03] <malcom2073> Read through that, it's fairly cleanr, but if oyu don't understand anything ask
[19:11:06] <malcom2073> clear*
[19:11:28] <pink_vampire> the release is 2.7.4, I see only 2.7
[19:11:36] <pink_vampire> where is the 2.7.4?
[19:12:07] <malcom2073> I'm unsure if they make the distinction for the download
[19:12:12] <malcom2073> Give that one a try though
[19:13:35] <pink_vampire> I can't find the link for the ***2.7.4***
[19:13:45] <malcom2073> Download what is on that page, and try it.
[19:14:04] <pink_vampire> there is now 2.7.**4**
[19:14:10] <pink_vampire> only 2.7
[19:14:20] <malcom2073> Download what is on that page, and try it.
[19:14:38] <pink_vampire> but it's not the last version.
[19:14:50] <malcom2073> Then don't try it, and enjoy crashing your machine :)
[19:14:50] <jdh> perhaps mach is a better choice.
[19:15:00] <pink_vampire> what is the point of download something that is not up to date??
[19:15:27] <malcom2073> You could downoad linuxcnc 2.0 and still accomplish what you want to accomplish
[19:15:33] <_methods> did this turn into the #mach3 room when i was walking the dog?
[19:15:36] <malcom2073> Which is: See if your machine has low enough latency to get the step rate you need
[19:15:41] <Sync> yes _methods
[19:15:50] <_methods> jeebus
[19:16:36] <malcom2073> pink_vampire: Fwiw: With the attitude you have towards it, I can almost 100% garuntee linuxcnc won't work for you
[19:17:12] <pink_vampire> all I'm asking is a link...
[19:17:32] <jdh> you have the link.
[19:17:44] <pink_vampire> jdh: show me,
[19:17:50] <pink_vampire> I can
[19:17:54] <Nate__> Hi
[19:18:11] <pink_vampire> I can't see any download for 2.7.**4**
[19:18:12] <_methods> hey Nate__
[19:18:17] <pink_vampire> only to 2.7
[19:18:19] <_methods> nastynate
[19:18:28] <_methods> do you know the squirrel master
[19:18:37] <Nate__> I'm new to Linux CNC, I used Mach 3 before.
[19:18:55] <cradek> the os updates will always install the latest minor version, along with bugfixes and patches to all the other software on the system
[19:18:57] <pink_vampire> so..
[19:19:01] <_methods> http://s2.quickmeme.com/img/23/23668615e605b5ea8b992f596fa71d8e8b9b9fb93160141e9ce830d86120bb45.jpg
[19:19:12] <_methods> i want your cocktail fruit
[19:19:28] <malcom2073> pink_vampire: So: Download the link. That's 2.7.4
[19:19:35] <malcom2073> .4 is implied
[19:19:45] <Nate__> How come the main page says that there are 2 current versions?
[19:19:56] <_methods> http://i160.photobucket.com/albums/t171/sneakysnake666/snapshot27.jpg
[19:20:42] <pink_vampire> http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso
[19:20:43] <pink_vampire> http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso
[19:20:49] <pink_vampire> that one?
[19:20:49] <Nate__> " Current releases: 2.7.4 2.6.12 "
[19:20:54] <malcom2073> Nate__: To quote jepler: "Typically, we maintain two different stable release versions of linuxcnc. At the moment, we maintain the 2.6 series and the 2.7 series. This is to help users who want to get linuxcnc with bugfixes but without the incompatible changes that can occur between two different series."
[19:21:05] <malcom2073> Nate__: So for new installs, use 2.7
[19:21:51] <Nate__> So this: http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso is 2.7.4?
[19:22:03] <cradek> the os updates will always install the latest minor version, along with bugfixes and patches to all the other software on the system
[19:22:23] <pink_vampire> it's downloading
[19:22:23] <cradek> I don't know what minor version is in that iso and it doesn't matter one bit because it's an OS install that will update after it's installed
[19:22:43] <pink_vampire> how do I install it?
[19:22:43] <Nate__> So once I have the ISO on, I need to do something like apt get update, to be current?
[19:22:44] <cradek> it's probably 2.7.0 and it DOESN'T MATTER
[19:22:54] <jdh> rtfm
[19:23:01] <cradek> pink_vampire: go to linuxcnc.org and start reading the very good docs that answer these initial simple questions
[19:23:27] <pink_vampire> 6min..
[19:23:27] <cradek> Nate__: you can do that, or the updater pops up by itself without you doing anything
[19:23:37] <jdh> everything you need to know is on the download link
[19:23:50] <pink_vampire> it will damage the xp installation?
[19:24:22] <cradek> yes, it's a full operating system. it does not run on windows.
[19:24:28] <Nate__> cradek: the download link is an iso file, not the manual...
[19:24:36] <cradek> that is also answered on linuxcnc.org
[19:24:59] <_methods> did the shortbus pull up in the parking lot tonight or something
[19:25:07] <Nate__> Thanks, I'll give it a go.
[19:27:00] <BeachBumPete> harsh
[19:27:17] <_methods> hehe
[19:27:34] <_methods> zlog
[19:28:29] <pink_vampire> 1m
[19:28:36] <_methods> ok mr margaritavill
[19:28:39] <_methods> e
[19:29:14] <_methods> you find a place for your machines BeachBumPete
[19:29:26] <BeachBumPete> yeah man
[19:29:27] <pink_vampire> I dont have a cd on the cnc computer
[19:29:47] <pink_vampire> and other ways to install it?
[19:29:48] <_methods> right one
[19:29:50] <BeachBumPete> working thru the mortgage process now on it. Hopefully soon we can NOT be homeless anymore
[19:29:54] <_methods> on even
[19:30:10] <_methods> where's all your stuff at now? in storage?
[19:30:17] <pink_vampire> hdd
[19:30:44] <Nate__> I don't have a CD either, can I install is using a USB stick?
[19:30:50] <djdelorie> you can usually use a usb stick instead of a cdrom
[19:31:00] <BeachBumPete> yeah stuck in a storage like a jigsaw puzzle consuming every square possible inch of space in two units
[19:31:01] <jdh> Nate: http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
[19:31:02] <pink_vampire> how?
[19:31:20] <Nate__> Will Unetbootin work?
[19:31:23] <_methods> so your new place has a good slab?
[19:31:29] <_methods> unetbootin will work
[19:31:37] <BeachBumPete> I suppose so ;)
[19:31:42] <djdelorie> depends on the image you're using, but typically, you just copy the image to the stick instead of burning it onto the cdrom
[19:31:49] <_methods> well plenty of room?
[19:31:51] <BeachBumPete> most homes in florida are on good slabs
[19:31:55] <_methods> tru dat
[19:32:13] <_methods> but i'm talkin you got 6" slab? or just plain old house slab
[19:32:14] <BeachBumPete> not as much as I had in tennessee but it is gonna have to do
[19:32:42] <BeachBumPete> honestly probably just house slab but my machine only weighs 7k
[19:32:47] <djdelorie> and by "copy to" I mean image copy, not drag files to it :-)
[19:32:49] <_methods> oh that's not too bad
[19:32:51] <pink_vampire> what it's Unetbootin??
[19:33:17] <pink_vampire> why it is sooo complicateeeed
[19:33:27] <_methods> so how much room you gonna have?
[19:33:29] <BeachBumPete> yeah and with the dispersal pods underneath it was not a problem in Tennessee which was probably not a thick slab either
[19:33:39] <_methods> dispersal pods?
[19:33:40] <pink_vampire> XXCoder: ?????????????
[19:33:44] <_methods> oh the leveling pads
[19:34:01] <BeachBumPete> I don't understand your question
[19:34:15] <BeachBumPete> yeah leveling pods
[19:34:16] <_methods> you're calling the leveling pads dispersal pods
[19:34:18] <Nate__> Unetbootin is a program that can take that .ISO download file, and copy it to a USB stick, it take care of the code required to boot it up on the computer instead of booting from a CD.
[19:34:30] <cradek> Nate__: http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_write_the_image_to_a_bootable_device
[19:34:32] <_methods> unetbootin will work
[19:34:32] <BeachBumPete> sorry I don't know the technical term ;) as usual
[19:34:58] <_methods> but following the docs is best idea
[19:35:07] <_methods> what cradek linked
[19:35:08] <cradek> yes second only to reading them
[19:35:14] <pink_vampire> cradek: dd??
[19:35:15] <_methods> lol
[19:35:20] <pink_vampire> in windows??
[19:35:31] <djdelorie> there's a dd for windows :-)
[19:35:46] <djdelorie> or you can download the rawread/rawwrite utilities
[19:35:50] <BeachBumPete> I am planning to build a large shed in the nice fenced in back yard to take a lot of the extraneous crap out of my shop so I can USe all of the available space for my work
[19:36:02] <_methods> ah nice that's what i did
[19:36:15] <_methods> all the dumb yard stuff and material is out in the shed
[19:36:26] <_methods> that way i can use the gayrage for machines
[19:36:29] <BeachBumPete> yeah I got tons of junk in there before
[19:36:46] <Nate__> Looks like the ''getting started'' part of the manual is lacking, no word on installing to a USB stick in Windows.
[19:36:49] <BeachBumPete> kids bikes, the kayaks, go karts, camping stuff, you name it
[19:37:05] <_methods> yeah
[19:37:18] <pink_vampire> someone need to update this page to the 21 century
[19:37:26] <BeachBumPete> the house we are buying is a good bit larger than our old one so hopefully some of that junk will find closets and atticks and stay out of my shop :D
[19:37:27] <jdh> Nate: document your install and update the page.
[19:37:29] <_methods> so you got a job down there?
[19:37:48] <BeachBumPete> you mean other than machining cool parts for people ;)
[19:38:08] <BeachBumPete> eh no not yet
[19:38:16] <_methods> hahah no wasn't sure if you were going to get a temp job or just had enough to hold you over till you were on your own again
[19:38:19] <Nate__> How, do you provide a login to the manual on the server?
[19:38:59] <BeachBumPete> my wife is working thru her pre employment stuff for her job and it is kinda ridiculously long process even tho she worked for the same company years ago here
[19:39:15] <_methods> ugh that sounds like fin
[19:39:17] <_methods> fun
[19:39:47] <Nate__> jdh: How do I login to update that page?
[19:39:47] <BeachBumPete> once we get the house and I can get our stuff moved over I will start seriously looking for at least part time work if not full time while I setup the machines and try to finish up the CNC lathe retrofit
[19:40:02] <_methods> i want to watch the new episode of silicon valley but the wife is makin me watch the braves get raped by the mets
[19:40:21] <BeachBumPete> you only have one TV? ;0
[19:40:29] <_methods> i'm too lazy to get off the couch
[19:41:00] <BeachBumPete> I feel ya
[19:41:00] <_methods> she watches it too though
[19:41:01] <jdh> Nate: submit the change to one of the maintainers.
[19:41:17] <pink_vampire> I need to get usb stick now ;(
[19:41:34] <BeachBumPete> been really trying to find a good deal on a vehicle for my wife lately here
[19:42:05] <_methods> always a crap shoot with used cars
[19:42:11] <_methods> and new cars are stupid price
[19:42:23] <_methods> just carjack someone it's florida
[19:42:26] <BeachBumPete> sure but a new car is out of the question...I hate throwing money away
[19:42:33] <_methods> lol
[19:42:43] <Sync> get her some dsm
[19:42:48] <Sync> and then secretly turbo it
[19:42:58] <BeachBumPete> went kayaking with my best friend Frank on Saturday
[19:43:07] <BeachBumPete> Sync LOL
[19:43:14] <BeachBumPete> he has a GORGEOUS car
[19:43:17] <_methods> F your kayak
[19:43:26] <BeachBumPete> ?
[19:43:30] <_methods> and don't post anymore pics in it lol
[19:43:33] <BeachBumPete> I love my my kayak
[19:43:34] <_methods> bastard
[19:43:47] <BeachBumPete> why?
[19:43:50] <_methods> make me jealous
[19:44:00] <BeachBumPete> they are not that expensive man
[19:44:12] <_methods> the kayak is the easy part
[19:44:18] <_methods> it's the time to go kayaking
[19:44:25] <BeachBumPete> caught some jacks, some cats, and a beauty keeper sheepshead
[19:44:35] <_methods> i love sheepshead
[19:44:41] <jdh> grouper season opened sunday
[19:44:42] <_methods> good eats
[19:45:00] <BeachBumPete> thats the best thing about kayaking, they are so easy to load and unload it is much quicker to get out to the water
[19:45:04] <Sync> you could rip zeeshan|2 off and machine torque plates BeachBumPete :P
[19:45:13] <BeachBumPete> I'll let you know how it tastes ;)
[19:45:21] <_methods> FU
[19:45:28] <Sync> the trick is, being able to boat to work ;)
[19:45:28] <jdh> boney, but taste good
[19:45:32] <BeachBumPete> anyways he has a SWEET car man
[19:45:43] <BeachBumPete> jdh it was bony actually
[19:45:51] <BeachBumPete> kinda surprisingly bony
[19:46:00] <jdh> not surprisingly. they are very boney
[19:46:17] <_methods> they sure taste good though
[19:46:19] <BeachBumPete> I mean not in the filet but the skeleton and there seemed to be kind of a ribcage around the gut area
[19:46:34] <jdh> yeah, I don't bother with them.
[19:46:44] <BeachBumPete> made fileting it a challenge but got it done
[19:47:07] <BeachBumPete> jdh did you say you had a suburban?
[19:47:19] <jdh> flounder just lay there and let you stab them. grouper and hogs kinda just hang out and you can shoot htem.
[19:47:29] <jdh> pete: yukon xl, same thing
[19:47:49] <jdh> my 3rd one
[19:47:58] <BeachBumPete> yeah I was looking at cars for Dacia and we kind of like that avalanche which I would think is similar no?
[19:48:59] <jdh> same chassis
[19:49:30] <BeachBumPete> I suppose.... I kinda like the whole changeover thing about it. Apparently the bed is like a longbed when you swap it
[19:49:42] <jdh> yeah, sounds like a PiTA
[19:50:00] <pink_vampire> linux cnc can handle 149867 pulsed per second over LPT?
[19:50:03] <BeachBumPete> I watched a video on it on youtube and it looked pretty damn simple
[19:50:06] <jdh> I used to dive with a guy that had one, he loved his
[19:50:40] <jdh> http://i.imgur.com/RcduwK1.jpg lightly loaded florida trip. rest of dive gear is in back seats
[19:50:51] <_methods> get her a big ole diesel dualie with a 5th wheel trailer that can haul around cnc machines
[19:50:54] <_methods> she'll love that
[19:51:11] <pink_vampire> someone?
[19:51:11] <BeachBumPete> jdh jeez man did you forget anything
[19:51:14] <malcom2073> pink_vampire: That depends entirely on your hardware. The latency test on the livecd will tell you what your hardware is capable of. That seems a bit high though
[19:51:29] <BeachBumPete> _methods yeah right
[19:51:34] <pink_vampire> ok
[19:51:37] <_methods> heheh
[19:51:42] <_methods> hey baby look what i got you
[19:51:49] <_methods> hahah
[19:51:53] <pink_vampire> I'm working now on the usb stuff.
[19:51:53] <BeachBumPete> I think the avalanche could haul a good bit probably tho
[19:52:03] <BeachBumPete> she does not mind a truck actually
[19:52:04] <pink_vampire> 99%
[19:52:14] <jdh> Pete: I had a weak moment and bought a VW wagon between yukons: http://www.artichoke.org/vw.jpg
[19:52:16] <_methods> sounds like a no brainer then
[19:52:17] <BeachBumPete> we used to have a fullsize Dodge Ram X cab 4x4
[19:52:19] <_methods> get her the damn dualie
[19:52:47] <Sync> BeachBumPete: put a 5th wheel adapter in it
[19:52:50] <BeachBumPete> only problem is I can't stand driving dually trucks
[19:52:59] <_methods> well you don't have to
[19:53:01] <_methods> she does hahahahhahahah
[19:53:19] <BeachBumPete> my dauhgter had a 3500 Ford dually 4x4 and that thing was like driving a schoolbus
[19:53:45] <BeachBumPete> I did use it to tow my CNC lathe down from KY to TN tho....pulled it like it was not even there
[19:53:54] <_methods> damn skippy
[19:54:06] <_methods> we got a 3500 and 4500 at work
[19:54:10] <BeachBumPete> honestly the lathe is like 3800 lbs or so the avalanche could handle that easily
[19:54:26] <BeachBumPete> hell my van could probably pull that
[19:54:27] <_methods> we haul stuff all the time with them on the 5th wheel
[19:54:41] <_methods> great for auctions
[19:54:50] <_methods> lot easier to get in and get out than with a semi
[19:55:03] <BeachBumPete> did you find me my fourth yet? ;)
[19:55:07] <_methods> but nice thing about a semi is you can bring your own forklifts
[19:55:12] <_methods> nah not yet
[19:55:17] <BeachBumPete> slacker
[19:55:20] <_methods> i'll get ya one sooner or later
[19:55:33] <_methods> i passed one up for you but it was a 4 spindle one
[19:55:40] <_methods> figured you wouldn't want that
[19:55:54] <BeachBumPete> 4 spindle collet?
[19:55:55] <_methods> was a 4 spindle tsugami
[19:55:56] <_methods> yeah
[19:56:06] <_methods> 4 spindle 4th axis
[19:56:34] <_methods> sorry tsudakoma
[19:57:26] <_methods> http://www.abltechnology.com/equipment-images/large/8114.JPG
[19:57:29] <_methods> like that one
[19:57:40] <BeachBumPete> aww you suck dude
[19:57:49] <pink_vampire> the computer don't like the usb :(
[19:57:51] <BeachBumPete> I might need more than one ;)
[19:57:54] <_methods> hahah
[19:58:00] <_methods> i almost bought it
[19:58:16] <_methods> i didn't think it would actually go for $500
[19:58:22] <_methods> so i didn't hit the bid button
[19:58:25] <_methods> and boom
[19:58:29] <_methods> sold
[19:58:35] <_methods> asshole got it for $500
[19:58:47] <Sync> haha
[19:58:49] <Sync> rekt
[19:58:54] <BeachBumPete> aw man now you REALLY suck
[19:59:00] <Tom_itx> you should have been the ass
[19:59:13] <_methods> i didn't think it would go
[19:59:20] <_methods> i thought someone else was going to hit it
[19:59:28] <BeachBumPete> I love that commercial with Benecio Del Toro...
[19:59:39] <_methods> my boss almost killed me over the haas tm-1's i lost
[19:59:54] <_methods> i dropped out at $8500
[20:00:13] <_methods> boss started yellin at me i told him to chill out i'll get the next one
[20:00:22] <_methods> guy buys both at $8500
[20:00:39] <BeachBumPete> Fuuuuuuuuu
[20:00:42] <_methods> yep
[20:00:49] <_methods> he was slappin the shit out of me lol
[20:00:53] <Sync> haha
[20:01:10] <_methods> he was going to give me the ez trak too if we got them

[20:02:13] <_methods> man ssi's new job sux
[20:02:18] <_methods> he's never on here anymore
[20:02:22] <Sync> yeah
[20:02:33] <BeachBumPete> yeah but he's probably makin' bank :D
[20:02:47] <BeachBumPete> so don't feel too sorry for him
[20:03:00] <_methods> hahah no
[20:03:04] <BeachBumPete> he'll be in here telling us about the new plane he bought
[20:03:07] <_methods> him and his airplanes
[20:03:48] <BeachBumPete> I'm here trying to buy a used truck for my wife and he is there buying a third or fourth airplane....what am I doin' wrong here LOL
[20:04:24] <_methods> right
[20:05:27] <_methods> i just wanna be like archivist when i grow up
[20:05:55] <BeachBumPete> he sure does have some nice toys huh
[20:06:18] <_methods> strange toys
[20:06:46] <BeachBumPete> strange is relative
[20:07:10] <_methods> i want to go over there and hang out with him and andypugh one of these days
[20:08:02] <Sync> hm, finally hooked one of the motors up to my zx45
[20:08:11] <pink_vampire> the max jitter is 75000
[20:08:19] <pink_vampire> it's good?
[20:08:19] <Sync> only running at 5m/min just yet
[20:08:22] <BeachBumPete> if I was gonna head to jolly old england I would find better things to do than hang with linuxCNC guys LOL
[20:08:36] <_methods> hahah
[20:08:42] <BeachBumPete> but I could be persuaded to have a pint with em one eve
[20:08:52] <_methods> Sync: is the zx45 like the sieg x3?
[20:08:59] <BeachBumPete> no
[20:09:01] <pink_vampire> the max jitter is 75000 is good??
[20:09:02] <pink_vampire> the max jitter is 75000 is good??
[20:09:03] <pink_vampire> the max jitter is 75000 is good??
[20:09:20] <FinboySlick> Not that great.
[20:09:27] <pink_vampire> but?
[20:09:30] <FinboySlick> Divide by 10 and it'll be good.
[20:09:31] <_methods> it looks pretty beefy
[20:09:32] <malcom2073> That's pretty bad heh
[20:09:59] <pink_vampire> how I can calculate the max pulses per sec?
[20:10:05] <_methods> looks kinda like that grizzly g0704
[20:10:16] <FinboySlick> So pete's slacking off at the beach? Is that what people do when they can't get busy with a proper lathe?
[20:10:25] <Sync> http://sync-hv.de/projects/3phase_troller/xachse3.mp4
[20:10:32] <BeachBumPete> you bet your sweet ass it is
[20:10:45] <BeachBumPete> Oh and kayak fishkin' too
[20:10:55] <malcom2073> pink_vampire: When you run stepconf it'll tell you
[20:11:01] <BeachBumPete> Damn I forgot how awesome saltwater fishing is
[20:11:13] <FinboySlick> Leave the sharks alone.
[20:11:22] <malcom2073> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration Also has a doucment for calculating it
[20:11:28] <BeachBumPete> when you catch something and it hits like a freaking freight train on your line
[20:11:43] <_methods> oooooh barracuda
[20:11:47] <BeachBumPete> even if it is not that big a fish LOL
[20:11:50] <pink_vampire> malcom2073: stepconf will tell me if it's reliable? or not?
[20:12:11] <malcom2073> pink_vampire: Stepconf will tell you your max step rate, but the calculator on the page I linked says 5556steps/second
[20:12:11] <BeachBumPete> I was on the bridge fishing this afternoon and a guy next to me caught a SWEET Snook keeper
[20:12:36] <malcom2073> That's pretty bad heh
[20:12:52] <_methods> wtf is a snook
[20:13:00] <BeachBumPete> a delicious fish man
[20:13:01] <malcom2073> Some jersey shore chick
[20:13:12] <BeachBumPete> no thats a snookie ;)
[20:13:19] <_methods> hahahha
[20:13:22] <malcom2073> :)
[20:13:30] <_methods> ah that thing looks bad ass
[20:13:37] <_methods> underbite from hell
[20:13:45] <BeachBumPete> http://andrewscharters.com/wp-content/uploads/Sanibel-Fishing-Charters3.jpg
[20:13:58] <_methods> catfish barracuda
[20:14:02] <BeachBumPete> very good eating
[20:14:20] <_methods> i bet she is
[20:15:32] <pink_vampire> ok
[20:15:36] <pink_vampire> 500mm/min
[20:15:37] <BeachBumPete> I gotta say catching a powerful fish off the kayak is VERY addicting...... that jack felt like it was gonna pull me outta the boat and it was not even that big
[20:15:43] <pink_vampire> it's fine
[20:16:09] <malcom2073> That's pretty slow
[20:17:17] <Sync> yeah
[20:17:34] <Sync> I'm at 10 times that much, and I'll still try to get double that
[20:19:51] <Duc_mobile> is it possible to program AB PLC without AB software?
[20:25:07] <jdh> no
[20:26:06] <Valen> Duc_mobile: which paticular bit of software do you want? I just dug up ultramaster!
[20:26:17] <_methods> no way i know of
[20:26:29] <Duc_mobile> Valen: I have all the AB training software so would like to pratice later on
[20:26:31] <BeachBumPete> _methods ya think I should just get her a Miata?
[20:26:37] <_methods> hahahah
[20:26:40] <_methods> yes
[20:26:43] <BeachBumPete> :D
[20:26:45] <Duc_mobile> cost work 5grand for the modules
[20:26:46] <_methods> for a woman that is fine
[20:27:01] <BeachBumPete> no man it would be for me ;)
[20:27:06] <_methods> homo
[20:27:07] <jdh> there is a freebie micro version
[20:27:16] <_methods> heheh
[20:27:25] <malcom2073> BeachBumPete: Guy here is selling a Supra with a chevy v8 in it :-D
[20:27:51] <BeachBumPete> https://miami.craigslist.org/mdc/cto/5544215779.html
[20:27:51] <_methods> supra = cool
[20:27:56] <_methods> miata = gay
[20:28:23] <_methods> pete = gay
[20:28:24] <BeachBumPete> malcom2073 Dear God why would you take an amazing thing like a 2jz out and put a GM lump of crap in such a beautiful car?
[20:28:29] <_methods> so i guess the equation works out
[20:28:34] <_methods> miata = pete
[20:28:36] <_methods> lol
[20:28:42] <malcom2073> BeachBumPete: Probably because it didn't have a 2jz or whatever it is in it?
[20:28:52] <BeachBumPete> so?
[20:28:57] <malcom2073> I would assume they come with different motors
[20:29:19] <FinboySlick> Speaking of cars, any of you guys familiar with Ford Smart Charge?
[20:29:30] <malcom2073> I enjoy chevy v8's. Sure they're not the most powerful in the world, but they're fun
[20:29:39] <malcom2073> And don't aggrivate migranes
[20:29:50] <FinboySlick> It's a feedback loop to change alternator load (and save fuel).
[20:30:12] <BeachBumPete> after seeing the 2jz on the dyno at that shop in Tennessee a few times......I'm a believer man
[20:30:18] <malcom2073> FinboySlick: Nope, but does it use falling rpm to charge more than when rising?
[20:30:23] <malcom2073> Cause that'd be cool
[20:30:32] <malcom2073> BeachBumPete: I can show you a 1200hp chevy v8, a single motor does not make a series :)
[20:30:54] <BeachBumPete> I can show you 2k HP 2jz's whats your point?
[20:31:00] <malcom2073> My point is you have no point
[20:31:20] <malcom2073> lumps if crap come in every variety
[20:31:29] <FinboySlick> malcom2073: I don't think it's that smart. It monitors battery temp and varies voltage accordingly though.
[20:31:32] <BeachBumPete> my point is that there is something beautiful about the simplicity and torque of an inline 6
[20:31:52] <FinboySlick> Thing is I think mine's kinda borked. I have a fairly dead battery in it and it refuses to feed more than 2.5 amps to it.
[20:32:11] <FinboySlick> Which means I'll have to drive 1500 miles before it's fully charged :P
[20:32:18] <malcom2073> heh
[20:33:47] <FinboySlick> Since all the doc says that it mostly works on voltage, I'm wondering why the amperage is so low. Voltage is spot on.
[20:34:03] <Valen> BeachBumPete: Ford AU falcon 4L inline 6 ftw
[20:34:07] <Sync> BeachBumPete: I understand why people drop in LSes
[20:34:12] <Sync> at least the Al block ones
[20:34:24] <Sync> they provide reliable power at r6 iron block weights
[20:34:40] <BeachBumPete> what's an iron block?
[20:34:45] <malcom2073> I like old chevy v8s because you can get them for the price of a pack of bubblegum
[20:35:05] <malcom2073> iron blocks are those things that last 50 years heh
[20:35:05] <BeachBumPete> but they could not pull the gum out of the wrapper ;)
[20:35:25] <malcom2073> depends on how hard your gum is, it's not like they're sub200hp
[20:35:32] <malcom2073> granted the power per liter is *terrible*
[20:35:38] <BeachBumPete> some were LOL
[20:35:59] <malcom2073> Yeah, but if you build one that slow, you're an idiot cause it costs the same to do one faster heh
[20:36:11] <BeachBumPete> ya know what the best motor I ever experienced was?
[20:36:54] <pink_vampire> I did the step conf
[20:36:55] <malcom2073> I enjoyed the klze
[20:37:01] <BeachBumPete> that damn 1.3 liter 4 cylinder in my suzuki samurai's..... I beat the living SHIT out of that truck and revved the berries off of it for years and it never broke even submerged it a couple times LOL
[20:37:05] <malcom2073> hha
[20:37:08] <pink_vampire> and the machine run perfect on the test axis
[20:37:12] <malcom2073> they were so tiny, I'll bet they were peppy
[20:37:19] <malcom2073> pink_vampire: Yeah?
[20:37:39] <malcom2073> pink_vampire: Linuxcnc does run machines *very* well... the tradeoff is the increased headache of configuration
[20:42:39] <BeachBumPete> I still say my perfect vehicle is a 4x4 diesel van.....but my wife doesn't want ANOTHER van SIGH
[20:43:00] <malcom2073> I have an expedition, I really wish I had gotten the diesel excursion
[20:43:19] <BeachBumPete> I like the excursion actually
[20:43:36] <jdh> but the market didn't
[20:43:57] <malcom2073> The diesels are two to three times the price of the gas ones heh
[20:44:22] <BeachBumPete> yeah but it still was a nice truck.... just the gas nazi's killed it
[20:44:24] <jdh> I rented the lincoln version of teh expedition to drive to NJ and pick up a boat. pretty nice ride
[20:44:35] <malcom2073> I love my expedition
[20:44:53] <malcom2073> But tge towing capacity is limited
[20:45:04] <jdh> yeah, but it wasn't mine, so who cares...
[20:46:38] <BeachBumPete> https://i.ytimg.com/vi/7ie99lFNt90/maxresdefault.jpg DROOL.... :D
[20:47:11] <malcom2073> haha
[20:50:39] <pink_vampire> malcom2073: how to I set the table size?
[20:50:50] <malcom2073> pink_vampire: In stepconf you set min/max travel on each axis
[20:51:02] <malcom2073> Be aware: Before you home, it ignores those limits
[20:51:02] <pink_vampire> mmm
[20:51:06] <malcom2073> once you home, it stops at the limit
[20:51:07] <pink_vampire> let me see
[20:51:15] <pink_vampire> let me see
[20:52:17] <jdh> that looks like a hippyredneckmobile
[20:52:35] <malcom2073> Yeah, BeachBumPete is a beach bum, not a backwoods hillbilly
[20:52:37] <malcom2073> Act the part man!
[20:52:41] <malcom2073> You need like a... vw bus
[20:52:47] <jdh> pop-top
[20:52:53] <jdh> peace sign on teh door
[20:52:57] <malcom2073> Yeah!
[20:53:03] <jdh> smoke coming out of teh window
[20:53:14] <BeachBumPete> jdh if that is hippy man then hand me the bong
[20:53:25] * jdh hands pete teh bong
[20:53:42] <djdelorie> pink_vampire: in stepconf wizard, there's spots for min/max on each axis; the size is the difference
[20:53:50] * BeachBumPete takes the first long toke ;)
[20:54:02] <djdelorie> make sure you set the home location correctly, or "0" if you're using the limit switches for homing
[20:54:28] <djdelorie> also, make sure for your Z axis, 0 is the *top* (max) and the bottom (minimum) is some negative number
[20:55:21] <gregcnc> that doesn't matter
[20:55:41] <djdelorie> it doesn't have to matter until you get that one rare gcode that moves to 0,0,0 and crashes
[20:56:16] <gregcnc> fire the programmer and operator?
[20:56:22] <pink_vampire> I want to set 120mm of travel
[20:56:28] <djdelorie> or the first time you home Z to 0
[20:56:34] <pink_vampire> to make it -60 to 60
[20:56:46] <gregcnc> that's how mine is set up
[20:56:46] <pink_vampire> or 0 to 120?
[20:57:05] <malcom2073> pink_vampire: 0 to 120
[20:57:08] <malcom2073> These are absolute values
[20:57:23] <pink_vampire> ok.
[20:57:26] <malcom2073> You can set work offsets wherever, but you want 0 to be the start, and 120 to be the end
[20:58:32] <pink_vampire> ok
[20:58:40] <pink_vampire> I did X 0 to 120
[20:58:47] <pink_vampire> Y 0 to 40
[20:58:54] <pink_vampire> Z -20 to 0
[20:59:05] <djdelorie> your mill is only 40mm?
[20:59:17] <pink_vampire> for now yes
[20:59:21] <djdelorie> ah ok
[20:59:47] <pink_vampire> I don't want the table fly all over
[21:00:16] <pink_vampire> how do I scale down the "linux cnc" test code?
[21:00:48] <malcom2073> I don't believe you can scale it, it's fairly small
[21:01:06] <jdh> move near zeros and touch-off
[21:01:50] <pink_vampire> is about 3 times the whole area
[21:01:56] <malcom2073> Tiny mill
[21:02:19] <jdh> mm/inch problem?
[21:02:28] <djdelorie> paranoia problem :-)
[21:02:54] <pink_vampire> no
[21:03:07] <pink_vampire> it's 120X40
[21:03:33] <jdh> mm?
[21:03:36] <malcom2073> I thought you had a bigger mill than that, that's really tiny
[21:03:41] <pink_vampire> yes
[21:03:49] <pink_vampire> i know
[21:04:00] <malcom2073> Well, you'll have to make your own test gcode for somthing that small
[21:04:01] <gregcnc> g0704 is that small?
[21:04:23] <jdh> g0704 is much bigger
[21:04:53] <pink_vampire> this is the size of the vise that I want the machine to work on it during the test.
[21:05:06] <gregcnc> why
[21:05:33] <malcom2073> You don't set your min/max to the min/max of the part you want to do
[21:05:37] <pink_vampire> 1HP servo on each axis can kill you
[21:05:39] <malcom2073> you set it to the min/max of your *actual* hardware
[21:05:43] <djdelorie> linuxcnc is going to find your limit switches and set the workspace according to those
[21:05:48] <malcom2073> That's what an estop is for fwiw
[21:06:09] <malcom2073> turn your feed rate way down
[21:06:11] <malcom2073> to like, 1%
[21:06:14] <djdelorie> after it knows what the absolute limits are and where the head is, it knows how to stay away from the limits
[21:06:20] <pink_vampire> i'm on 30mm.
[21:06:26] <pink_vampire> mm/min
[21:06:35] <djdelorie> this is independent of where your part origin and space are
[21:07:53] <pink_vampire> I'm sure there is a way to shrink the test file.
[21:07:59] <djdelorie> on my machine, there's a lot of things it refuses to do until it's been homed and it knows where's safe to go
[21:08:13] <gregcnc> linuxcnc will stay within soft limits. if a hard limit is tripped, configured correctly it should estop.
[21:08:21] <jdh> you can change your scale
[21:09:02] <pink_vampire> ok
[21:09:10] <pink_vampire> i re open linux cnc
[21:09:18] <pink_vampire> and it shrink it down..
[21:09:56] <gregcnc> it scales that bit of code to fit the machine? who knew
[21:10:27] <jdh> I would consider that 'the wrong thing to do'
[21:10:29] <djdelorie> gregcnc: on my machine, home==limit, so soft limits are hard limits
[21:10:30] <jdh> but...
[21:10:52] <gregcnc> so you have no physical switches?
[21:11:44] <malcom2073> Yeah if you scale it, you never know if it's gonna crash the machine
[21:11:51] <malcom2073> Better to not lie to linuxcnc.
[21:12:20] <jdh> I would not want to crash servos likethat.
[21:12:30] <djdelorie> gregcnc: I have limit switches on both ends of each axis (six total) but no separate home switches
[21:12:49] <gregcnc> right but soft limits are somewhere inside those?
[21:12:51] <djdelorie> the limits are far enough away from the actual physical stops that he servos can stop in time (the controllers know)
[21:13:04] <djdelorie> no, it uses the full work area
[21:14:01] <djdelorie> there's like a 1/2" margin for X and Y, and 1/8" for Z, plenty of room to stop
[21:14:57] <gregcnc> so when up against the soft limit you get a limit swtich tripped signal?
[21:15:18] <djdelorie> yes
[21:15:59] <pink_vampire> http://pastebin.ca/3589108
[21:16:01] <gregcnc> i don't think that's a common setup
[21:16:09] <pink_vampire> that will work on linux cnc??
[21:16:18] <pink_vampire> I did it now on hsm
[21:16:20] <malcom2073> pink_vampire: Looks like a bunch of numbers.
[21:16:28] <jdh> ugly code
[21:16:28] <malcom2073> Why don't you load it and se?
[21:16:51] <pink_vampire> I don't want to crush the machine...
[21:16:54] <djdelorie> gregcnc: it's one of the supported setups, and the parallel port doesn't have that many inputs...
[21:17:07] <djdelorie> pink: lower the feed rate override to 10% to start
[21:17:22] <pink_vampire> I want to know if you think that look like a valid linux cnc G code,
[21:17:48] <malcom2073> pink_vampire: Sure it looks like it, but no way to tell for sure unless you load it up and see
[21:17:52] <gregcnc> load it, linxuxcnc will read it at tell you if there is an error
[21:17:54] <malcom2073> Set your feed rate down to like 1%
[21:18:09] <malcom2073> It'll move at 1% speed, easy to estop before damage
[21:18:09] <pink_vampire> ok
[21:18:37] <pink_vampire> mm
[21:18:41] <pink_vampire> I can't!!
[21:18:50] <djdelorie> can't what?
[21:18:51] <pink_vampire> I need a network !
[21:19:01] <malcom2073> Stick it on a usb stick, that's how I move stuff over to my mill
[21:19:11] <pink_vampire> the mach3 work with the windows share.
[21:19:22] <djdelorie> linux knows about windows shares too
[21:19:43] <pink_vampire> let me see
[21:20:00] <djdelorie> obviously you have to set up your network and attach the share first :-)
[21:21:06] <pink_vampire> I'm looking for a usb stick.
[21:25:50] <pink_vampire> it has a problem with line 9
[21:25:58] <pink_vampire> http://pastebin.ca/3589108
[21:26:18] <pink_vampire> I need to set the tool??
[21:27:34] <pink_vampire> N30 T6 M6
[21:27:47] <pink_vampire> any help??
[21:28:59] <djdelorie> no idea from me
[21:29:06] <djdelorie> just take out that line :-)
[21:30:17] <Tom_itx> it's probably a line above that tool change
[21:30:32] <Tom_itx> are you using any H words with it?
[21:30:42] <Tom_itx> oh yeah that's further down
[21:32:09] <Tom_itx> what's g91.1?
[21:32:23] <Tom_itx> seems wrong with the G90 on the same line but i'm not sure what the .1 is
[21:33:08] <gregcnc> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g90.1-g91.1
[21:33:13] <Tom_itx> G90 is absolute and G91 is incremental
[21:33:58] <Tom_itx> so are you telling it to do both modes at once?
[21:35:20] <Tom_itx> i don't think you want to mix those modes there
[21:35:54] <Jymmm> It's like mixing matter and anti-matter, ya just dont do it, mkay
[21:36:14] <Tom_itx> so the T6 M6 isn't your problem
[21:39:41] <gregcnc> I think the problem is the Z. between G43 and H6
[21:40:19] <Tom_itx> it could be
[21:40:36] <Tom_itx> the H word is activated on the first linear move
[21:41:04] <Tom_itx> and that's no move because it's already at Z0
[21:41:51] <Tom_itx> i'd move it to a short feed move to the work surface or something
[21:42:36] <Tom_itx> N3 G43 Z0.1 H1
[21:42:40] <Tom_itx> that's what i do
[21:44:07] <Tom_itx> but she left anyway
[22:00:37] <os1r1s> I have some blue fluid leaking out of my spindle. Any suggestions on what that might be? This is a g0704 llook alike
[22:01:25] <malcom2073> Did you accidently get some cleaner in there that dissolved some of the grease?
[22:01:29] <malcom2073> I'd assume they're sealed bearings
[22:02:00] <os1r1s> malcom2073 No, definitely didn't get cleaner in there
[22:02:12] <os1r1s> Its a lot of blue fluid
[22:02:25] <os1r1s> Probably .5 oz to 1 oz guessing ...
[22:02:30] <malcom2073> My only guess is that it's the grease separating somehow, did you overheat it?
[22:02:42] <os1r1s> Nope. It was actually leaking when I got it
[22:02:56] <malcom2073> hmm, maybe they overheated it
[22:03:01] <os1r1s> I can contact precision matthews. Just not sure if someone had an idea
[22:03:07] <malcom2073> I've seen yellow, green, and orange grease, blue wouldn't shock me
[22:10:53] <Jymmm> malcom2073: (Dude, TMI)

[22:41:24] <CaptHindsight> http://www.ebay.com/itm/161605325081 bt40
[22:41:34] <zeeshan|2> nice
[22:42:53] <CaptHindsight> I have to replace the spindle so I might go with something 10K rpm +
[22:43:01] <zeeshan|2> whats wrong with yours
[22:43:16] <CaptHindsight> bearings are acting up
[22:43:36] <CaptHindsight> so it's not really that much more work for me to upgrade
[22:44:08] <zeeshan|2> for me i want to speed my stuff up
[22:44:13] <zeeshan|2> but the problem is the gear train
[22:44:18] <zeeshan|2> i dont think it'll like being oversped

[22:49:22] <CaptHindsight> zeeshan|2: since you're making many of the same parts would a dual spindle machine help?
[22:49:35] <zeeshan|2> probably
[22:49:40] <zeeshan|2> but i think fixturing is the key
[22:49:48] <zeeshan|2> i dont mind the machine running for hours, i just hate being in front of it
[22:50:03] <zeeshan|2> if i can machine 12 at a time, and leave it running for 5 hours
[22:50:03] <CaptHindsight> not very exciting
[22:50:04] <zeeshan|2> that would be idea
[22:50:08] <zeeshan|2> *ideal
[22:52:21] <CaptHindsight> this is usually a good time to find machines
[22:52:29] <zeeshan|2> why
[22:52:32] <zeeshan|2> economy is doing well :P
[22:52:32] <CaptHindsight> lots of spring cleaning at shops
[22:53:10] <CaptHindsight> the used machine market is really slow right now
[22:53:17] <CaptHindsight> at least in the US
