[00:34:47] <Erant> minibnz: Shift register.
[00:35:03] <Erant> Buffered shift register to be precise.
[00:35:22] <Erant> CLK, DATA, !ENABLE
[00:37:54] <minibnz> its a l289 driver board so there are lots of designs on the net if i need them its pretty popular i want to use it as a dual DC motor driver most interfaces are for steppers but i can still get what i need.
[00:39:10] <minibnz> at the moment all i think i need to drive with it is the tool changer motor maybe a grinder motor for when if i want to spin a diamond disc at the right speed.
[00:39:51] <minibnz> these can wait until i haev more $$$ spare and maybe a job :)
[00:41:07] <minibnz> tool changer is pretty useless with only one tool that fits the collet at the moment, need to find some tool holders
[01:10:39] <tiwake> CaptHindsight: you around?
[01:11:04] <tiwake> CaptHindsight: I really want to buy/try some of your solvent based dye
[01:11:51] <CaptHindsight> I'll be asleep for the next 10-11 hours
[01:12:01] <CaptHindsight> try me then
[01:12:12] <tiwake> alright
[01:50:09] <minibnz> oh that was a mission... finally got it all back together now i need to remap the pins to my new drivers :)
[02:05:59] <minibnz> hmmm everything seems ok except i am permanently in estop :( and cant change it in software. gotta work out how to bypass the hardware pins in the hal file. i had a loop back from pin 1 to pin 11 but not putting that on at the moment
[02:06:18] <minibnz> that will mean taking the box down again.. not today.. not this week..
[02:09:45] <minibnz> plenty of pages on enabling but even when i hash out all the estop lines in the hal file i still cannot enable it :(
[02:23:08] <Deejay> moin
[02:23:14] <minibnz> this is retarded.. i am going to have to add a physical wire to the pins i just cannot find any info on removing the estop once you have added it.. now its sounds stupid i should be able to simply hash out the lines i added to turn off but no i seem to be missing something.
[02:39:15] <minibnz> oh hardware wins again.. going to have to add a loopback wire..
[02:40:19] <minibnz> cant find anything to follow and if i remove (not just hash out the estop lines) it still wont work.. and i know the file is right cuz i can break my work lamp settings which are in that file and it does what i tell it..
[02:40:50] <minibnz> going to try and carry a hot soldering iron to the mill to attach the wire..
[02:56:07] <FloppyDisk> Erant - stay away from my wabeco:-) hahahahah.... j/k. I haven't decided if I will go to the auction, but if you're going, I might try a little harder.
[04:17:23] <minibnz> yeah happy now.. i got all the must do things sorted out on my mill now the other things are still there to be done but there is no rush i think its at the point where i can sit back and dream for a little bit :)
[04:18:12] <minibnz> the extra fan seems to be helping a hell of a lot dumping all that heat thats in the box.. it doesnt really help when its nearly 9pm and feels like its 33'c in there..
[04:18:26] <minibnz> no air con in the work room :(
[05:21:47] <jthornton> yippie 13 stone today only 1/2 stone to go
[05:24:05] <SpeedEvil> jthornton: http://www.amazon.com/Kraft-Macaroni-Cheese-Dash-Button/dp/B00WJ13MVM
[05:29:43] <archivist> cake
[05:36:06] <jthornton> I wonder what Andy did here to lift the frame http://bodgesoc.blogspot.co.uk/2015/08/holbrook1.html
[05:36:42] <jthornton> oh I think I see it now the castor is mounted to an inner part that the screw pushes on
[05:39:20] <jthornton> after tipping my Samson over once I made this to move top heavy stuff and well any thing I needed to move http://gnipsel.com/shop/gantry/gantry.xhtml
[05:45:24] <archivist> he is also using strapping between frame and under lathe
[05:46:23] <archivist> I still use rollers, levers etc
[05:52:52] <_methods> yeah i like my machines firmly attached to the ground
[05:53:34] <_methods> i'm always leary of moving heavy machines on casters
[05:53:46] <jthornton> I was lucky to have the steel as drops from other jobs so why not put it to good use
[05:53:48] <_methods> seen too many tipped when they hit a crack or chip on the floor
[05:55:19] <_methods> yeah lift is the way to go
[05:55:56] <_methods> not many things are more horrifying than watching a machine go over
[05:57:02] <jthornton> when the Samson started over the other guy there helping me move it started to move to it to stop it and hollered no
[05:57:24] <_methods> yeah you're not stopping that train once it's in motion
[05:57:33] <jthornton> only broke two hand wheels and bent the X screw a tad
[05:57:44] <_methods> wow
[05:57:48] <_methods> got lucky on that
[05:57:49] <jthornton> sure got my respect in a hurry
[05:58:03] <_methods> it will put a nice whole in the slab too
[05:58:07] <jthornton> yea IIRC there was some other stuff that slowed it down
[05:58:38] <_methods> it's real bad when they drop off the truck lol
[06:00:00] <jthornton> when I unloaded the BP VMC the fork lift was too small and I had to use straps to keep it on the lift
[06:00:16] <_methods> heheh
[06:00:32] <jthornton> I lifted it up and the truck drove out from under it and then I backed my trailer under and slowly lowered it down
[06:00:33] <_methods> i've found the best riggers are just very slow and methodical
[06:00:42] <_methods> and they never stress over anything
[06:00:50] <jthornton> http://gnipsel.com/shop/unload-308/unload-308.xhtml
[06:01:01] <jthornton> that took a 3 day weekend
[06:01:02] <archivist> we moved a steam engine on a gantry crane, the legs started bending outwards
[06:01:26] <_methods> yeah i try to just move slow and keep the machine as close to the ground as possible at all times
[06:01:51] <archivist> slow and near ground means less damage
[06:01:51] <_methods> getting things on and off the truck is usually the worst part
[06:02:23] <aventtini3> hello guys
[06:02:24] <jthornton> the most amazing riggers I watched was on the nuke subs they would move equipment down the passage way with chain falls and they were so good the equipment moved horizontal with no up and down motion
[06:02:28] <_methods> once you get past that it's typically just a matter of not doing stupid stuff to get around obstacles
[06:02:41] <archivist> its hard sometimes getting rid of thick helpers, when you want to be slow and methodical
[06:02:42] <aventtini3> can any one give me the link to 2.7.4
[06:02:52] <aventtini3> my mozzila dont work on the web now
[06:03:05] <_methods> to the livecd?
[06:03:08] <jthornton> you get 2.7.0 and upgrade to .4
[06:03:31] <aventtini3> the i upgrade
[06:03:41] <aventtini3> iso
[06:04:04] <aventtini3> the axis drift away with 2,7
[06:04:07] <aventtini3> in continus
[06:04:13] <jthornton> http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso
[06:04:14] <aventtini3> if i install 2.6
[06:04:19] <aventtini3> it works perfect
[06:04:29] <aventtini3> i cant understand why
[06:04:35] <aventtini3> i have set the setups
[06:04:48] <aventtini3> offsets
[06:04:59] <aventtini3> on the servos
[06:14:31] <jthornton> https://www.youtube.com/watch?v=dzX0JXX5iCc
[06:24:31] <aventtini3> anyone?
[06:24:43] <aventtini3> 3 machines same drives
[06:24:48] <aventtini3> same problem on 2.7
[06:25:03] <aventtini3> and all of them work perfect on 2.6
[06:26:05] <aventtini3> drives are bosch
[06:41:27] <minibnz> do ypu havean oscillioscope? maybe the pulse widths have dropped for some reason or you have some new noise
[07:34:22] <aventtini3> i dont have
[07:34:25] <aventtini3> same deal
[07:34:44] <aventtini3> but all 3 of the machine same problem
[07:37:25] <aventtini3> in the dac its moving ok
[07:37:32] <aventtini3> no funny moves
[07:37:43] <aventtini3> when i start to jog
[07:37:52] <aventtini3> it stops
[07:38:07] <aventtini3> i made the servo offset on the drive
[07:38:13] <aventtini3> its stay on 0
[07:38:32] <aventtini3> and for some reson it starts bay him self
[07:38:43] <aventtini3> when i test with DAC
[07:38:46] <aventtini3> its ok
[07:38:54] <aventtini3> it moves perfect
[07:39:47] <minibnz> so you are saying that everything is ok but then after a period of time the axis start to move by themselves?
[07:40:52] <minibnz> or is it that the axis are not keeping up with your desired move? ie you tell it to move 100mm and it stops because the encoders are saying there is a tracking error?
[07:41:37] <minibnz> do you drivers have software controlable current settings?
[07:42:16] <aventtini3> its from 2.7
[07:42:29] <aventtini3> im working whit 2.6
[07:42:34] <aventtini3> same configuration
[07:42:39] <aventtini3> for 6 months
[07:42:45] <minibnz> yeah i see thats what you are saying but i am trying to work out what is different.
[07:43:23] <minibnz> have they made any changes to the layout of the configurations maybe the old config is not 100% compatible.
[07:43:33] <aventtini3> conf is new
[07:43:47] <aventtini3> i see the P is 50 in this new version
[07:43:52] <aventtini3> old one use 1
[07:43:58] <aventtini3> and it works perfect
[07:44:08] <aventtini3> olso f1 is 0
[07:44:11] <aventtini3> here is 1
[07:44:17] <aventtini3> on new
[07:44:33] <archivist> transfer your settings to work properly
[07:44:37] <aventtini3> i did change like the old one but no result
[07:45:09] <aventtini3> actualy i was thinging the drives has there own P
[07:45:14] <minibnz> im sorry i cant help you i have no idea what you mean by the new version is p 50. .
[07:45:29] <aventtini3> the onlydifferance is the P
[07:45:40] <aventtini3> PID
[07:45:41] <minibnz> do you mean P as in PID
[07:45:47] <aventtini3> yes
[07:45:55] <minibnz> ahh ok still cant help you sorry i use steppers.
[07:46:01] <aventtini3> -5v +5 scale 10v
[07:46:32] <rob_h> how do you have the drive enables set?
[07:46:51] <rob_h> as if they are under PID the PID should hold them inpostion when PID and drive is enabled
[07:46:53] <aventtini3> yes
[07:47:39] <archivist> was not a yes no question
[07:48:04] <aventtini3> i have all the enable conected on machine ON
[07:48:09] <aventtini3> not on a pin
[07:48:45] <minibnz> how far does it move before the problem shows up?
[07:48:46] <aventtini3> it give a 24v to a relay on machine on
[07:48:54] <aventtini3> ramdom
[07:49:27] <minibnz> sounds like a floating pin..
[07:49:44] <aventtini3> imposible on 3 machine
[07:49:58] <aventtini3> all of the has same motor and drives
[07:50:16] <aventtini3> my cd is 2.7
[07:50:17] <minibnz> not if you are using the wrong configuration on all of them.. ie forgetting to configure a pin.
[07:50:21] <rob_h> Halscope the output of the PID and feedback and see if its commanded or not
[07:50:22] <aventtini3> 2.7,0
[07:51:00] <archivist> sounds like he has not transferred the PID numbers from old to new
[07:51:17] <aventtini3> thy on the DAC its working perfect
[07:51:29] <minibnz> ahh so the pid controller is wigging out randomly..
[07:51:29] <aventtini3> drive stays in place
[07:51:34] <aventtini3> no funny moves
[07:51:48] <minibnz> when you use the dac does the PID get involved or is it open loop?
[07:51:53] <aventtini3> DAC is not using the pid ?
[07:52:05] <aventtini3> no open loop
[07:52:22] <aventtini3> linar scales bosch whit tachos
[07:52:46] <minibnz> ok so if your PID loop is involved things go wrong? maybe its the feedback settings.
[07:53:00] <rob_h> can you show your HAL?
[07:53:10] <rob_h> maybe someone can look at it and see if something funny
[07:53:20] <minibnz> you havent crossed your axis or anything like that have you? ie set scale for Y to trigger X axis?
[07:53:56] <rob_h> for axis enable i do something like this, http://pastebin.com/6BkbYmR2
[07:54:29] <aventtini3> one sec let me get it
[07:57:44] <aventtini3> http://textuploader.com/521xk!
[07:58:11] <minibnz> oh you have a 404 error that could be the issue :p
[07:58:35] <aventtini3> http://textuploader.com/521xk
[07:58:42] <archivist> remove the ! from the url
[07:59:25] <aventtini3> i have tested all the ways i can imagine
[07:59:30] <archivist> aventtini3, why are you recreating the hal file instead of editing/transferring the old one
[07:59:44] <aventtini3> now im downgrading to 2.6
[08:00:09] <aventtini3> no its a new hal
[08:00:30] <archivist> that is why!
[08:00:40] <archivist> use original settings
[08:00:55] <aventtini3> http://textuploader.com/521x4
[08:01:07] <archivist> you are forgetting to tune your drives
[08:01:24] <aventtini3> no
[08:01:36] <aventtini3> thats the problem i cant tune them
[08:01:54] <archivist> use your original hal
[08:01:55] <aventtini3> it run's ways
[08:02:12] <aventtini3> insted onf the 2.7?
[08:02:13] <archivist> you are not connecting it properly
[08:02:20] <aventtini3> imposible
[08:02:43] <aventtini3> all of my 3 machines make same problem
[08:02:47] <aventtini3> no one
[08:02:49] <archivist> I never have that confidence in my work
[08:03:00] <aventtini3> its same configuratiin
[08:03:09] <archivist> I know where mistakes happen, user
[08:03:18] <aventtini3> thats the ugly part
[08:03:22] <minibnz> have you confirmed that with a diff command?
[08:03:26] <aventtini3> let me down grade and see
[08:03:35] <aventtini3> no
[08:03:53] <aventtini3> i realy nead the new TRAJ
[08:03:59] <archivist> use a diff, eg meld is a nice visual one
[08:04:01] <minibnz> that might be a start.. as you say its on three machines so it really should be a setting somewhere.
[08:04:02] <aventtini3> thats whay i need to upgrade
[08:04:36] <aventtini3> then why im not seetting the 2.6 bad
[08:04:47] <aventtini3> limits are llimits
[08:04:49] <minibnz> well if you can see whats different maybe its a new setting thats conflcting with an old one..
[08:04:59] <archivist> feedback connections
[08:05:15] <aventtini3> new hdd
[08:05:30] <minibnz> archivist you are talking about the nets in the hal files right?
[08:05:34] <archivist> yes
[08:05:38] <aventtini3> i did not test the encoders direction
[08:05:38] <minibnz> no pyhsical connections..
[08:05:43] <minibnz> not^
[08:06:06] <aventtini3> one sec
[08:06:08] <archivist> all the wiring will be ok, he is not setting the hal correctly
[08:06:40] <rob_h> if runs away 9/10 its encoder direction motor trying to catch up
[08:06:48] <archivist> dunno why people get suckered into these conf programs
[08:06:55] <rob_h> y i always park machine in middle when new fitting
[08:07:13] <minibnz> yeah thats where i am at too.. sounds like when he has not PID in use the servo's work in open loop.. if PID is involved things happen that shouldn't.. i would be looking at the PID stuff
[08:07:33] <rob_h> dont know why regenerate if works on 2.6 why not copy all the config and nc folders... im sure he wants to keep his programs too
[08:07:58] <archivist> that is the really silly bit, not starting with old config
[08:08:20] <minibnz> from the sounds of it he needs the conf wizard to set some new settings that 2.7 supports.
[08:08:46] <archivist> you can diff those in separately
[08:08:49] <rob_h> is rigid tapping ment to work in U V W? or should it not work at all.. as right now it seems to half work
[08:08:57] <minibnz> while i see what he is trying to do.. i would only use the new conf as a reference and add the bits i need one at a time to the known working config.
[08:10:45] <minibnz> probably been staring at it for too long and is all messed up in his mind. i know i get like that dealing with the hal and ini filed
[08:10:48] <minibnz> files.
[08:11:50] <rob_h> you mean when u have a G code problem and u cant find it.. then have a cupa and come back you find it rgiht away some silly typo but in your mind you right it correct
[08:11:53] <minibnz> like today i wanted to remove the estop loopback but failed misserably.. had to add a wire in the end.. just could not get it to .. not work :)
[08:12:06] <minibnz> exactly...
[08:31:43] <aventtini3> did not work
[08:31:48] <aventtini3> tuning is not posible
[08:32:02] <aventtini3> it give 1 mm
[08:32:16] <aventtini3> it dot give any speed to the move
[08:32:28] <archivist> if you have not set up your hal correctly you wont be able to tune
[08:32:32] <aventtini3> only if i give ff1 to 1
[08:32:45] <aventtini3> the it starts to go like it shod
[08:33:01] <aventtini3> hal is the old one
[08:33:34] <aventtini3> let me instal the 2.6
[08:33:40] <aventtini3> the upgrade to 2.7
[08:34:07] <aventtini3> ff0 gives it a boos on movment
[08:34:20] <aventtini3> 1500mm and it moves like a duck
[08:34:23] <aventtini3> :)))
[08:34:33] <minibnz> if you are sure all the settings are the same then 2.7 must be interepeting them wrong. maybe they changeed a format of a variable or something that is stopping it from working properly is there anything in the change log about the hal or ini file formats?
[08:35:04] <aventtini3> let me test 2.6
[08:35:13] <aventtini3> and see
[08:35:24] <aventtini3> i will make pick of the settings
[08:36:12] <minibnz> the other thing it could be is that the firmware for your mesa card has changed with the new version maybe? i was reading on the mesa site that you can load different firmware to make the ports act differntly..
[08:36:55] <minibnz> is there any firmware packaged with linuxcnc or is that done seperately?
[08:37:23] <minibnz> i dont have a mesa card yet.. still reading up on all the things it can do.
[08:49:31] <MonoAngularJS> Hi
[08:51:45] <MonoAngularJS> i have a problem with bash script
[08:53:06] <minibnz> whats the problem mono?
[08:54:16] <MonoAngularJS> i have a script
[08:54:17] <MonoAngularJS> I have a script that walks if executed with relative path and do not if it runs with absolute path
[08:57:55] <minibnz> sounds like that could be a stray ../ in there somewhere without looking at the script..
[09:03:24] <minibnz> <aventtini3> i found this in the changelog encoder: document the surprising encoder num_chan=0 behavior in manpage but i cannot work out what they are refering to as suprising
[09:03:37] <minibnz> where is the man page for linuxcnc?
[09:03:39] <MonoAngularJS> I think it has to do with a default route or something
[09:03:56] <minibnz> oh its in the terminal.
[09:04:00] <MonoAngularJS> I think it has to do with a default path or something
[09:06:42] <minibnz> oh i dont have the right version of linuxcnc that has this update
[09:12:37] <minibnz> ok bedtime for me..
[09:12:41] <minibnz> talk with you all later..
[09:44:55] <zeeshan> hi
[09:46:21] <JT-Shop> bye
[09:46:59] <zeeshan> :)
[09:47:58] <Roguish> JT-Shop: hey, how's it going man? store front looks good, but you need a pretty girl on the front....
[09:50:28] <MonoAngularJS> how to install deamontools
[09:52:23] <MonoAngularJS> I can't do it to work
[09:53:35] <archivist> what has deamontools got to do with linuxcnc
[09:57:22] <yasnak> How accurate can you hold 3d printed parts?
[09:58:02] <archivist> how accurate were they made :)
[09:58:19] <yasnak> Never really used them for actual prototyping so that all depends...
[09:59:01] <yasnak> I need a faster solution to new product prototyping. Our engineers suck, and I need faster answers to their crappy designs. Right now us machinists tool up and run knowing the design sucks and won't work. We spend alot of time proving this.
[09:59:41] <archivist> us and them problem :)
[10:00:29] <yasnak> Eh, somewhat. We don't really make mistakes. We make what the print specifies. I need to teach by rubbing nose in end product at this point. I just can't be wasing thousand + hours doing it.
[10:00:30] <Roguish> yasnak: why are you bagging on the engineers?
[10:01:06] <pcw_home> aventtini3: as other have said, use your previous config files, your current ones are broken
[10:01:21] <Roguish> get the engineers into the shop, away from the screens so they realize their ways...
[10:01:26] <yasnak> Because it ultimately falls back on them, when you're design has actuators that aren't actually held in position and you make the assembly work by mating it to another piece that actually won't work in real life it becomes an issue of "what are you smoking dude?"
[10:01:50] <yasnak> Roguish, I'm trying that as well. But as you know they have alot to do as well. I just don't know the best solution to this.
[10:02:02] <Roguish> talk and communications are key.
[10:02:33] <archivist> it is unfortunate that modern designers dont get an apprenticeship on the floor making stuff
[10:02:39] <Roguish> the engineers should solicit comment from the mechanics and machinists, the visa-versa.
[10:03:11] <Roguish> 'and' visa-versa
[10:03:17] <yasnak> Oh we do, but then there is the issue of the suggestions getting lost in translation. Next rev is released with none of the issues brought up previously being fixed. Blah blah
[10:03:47] <Roguish> could this be a 'leadership' problem?
[10:03:53] <tiwake> enh
[10:03:58] <archivist> have to be recorded so you can rub noses in the list of errors
[10:04:01] <pcw_home> aventtini3: LinuxCNC 2.7.x uses the same config files as 2.6 with some minor
[10:04:03] <pcw_home> exceptions so its _MUCH_ easier to use your working hal/ini files than start from scratch
[10:04:05] <yasnak> Apprenticeship is key really, they're modeling things that aren't possible to be machinined or would take endless hours to machine.
[10:04:22] <yasnak> Yes recorded. Leadership is an issue.
[10:04:42] <tiwake> engineers should work out on the shop floor for a year or two in a general job shop
[10:05:12] <yasnak> My boss is a GET IT DONE NOW dude. But we're also regulated and have massive amounts of ISO involved. So its a push pull deal in which us machninists end up being the ones who must make sure everyhting is right. And that really slows us down.
[10:05:13] <Roguish> yasnak: i agree with that, I am the 'engineer', and have always felt 'new engineers' especially ones fresh from school should spend a bit of time 'on the floor'
[10:05:27] <zeeshan> Roguish: you and me both know
[10:05:33] <zeeshan> most engineers haven't fucking touched a machine in their life
[10:05:39] <yasnak> ;/
[10:05:43] <zeeshan> and give us a bad name
[10:05:47] <zeeshan> i encounter this DAILY!!!
[10:05:54] <zeeshan> but they're definitely not dumb.
[10:05:57] <yasnak> See, thats just it. I get so frustrated. Things that seem so common sense to me are anything but common sense.
[10:05:57] <zeeshan> its lack of physical experience
[10:06:30] <archivist> too easy these days to 3d design the impossible
[10:06:31] <zeeshan> yasnak: honestly, i could make a machinist feel dumb too.
[10:06:33] <Roguish> I know, and it sucks. my nephew just finished his EE, and had never opened a simple outlet in a house 'til he helped me....
[10:06:44] <zeeshan> they don't understand half the engineering stuff ..
[10:06:48] <zeeshan> i'm not an ass about it though
[10:06:49] <yasnak> Zeeshan, please humble me. I think that may be the issue sometimes :P
[10:07:01] <zeeshan> the other day a guy asked me "what is this unit 1 m^3"
[10:07:06] <zeeshan> he's an EXCELLENT machinist
[10:07:07] <Roguish> schools only teach a little bit. the rest in OTJ.
[10:07:22] <yasnak> I'm a cross between programmer, machinist and mechanical engineer. Never finished school. Been doing this since I was 16.
[10:08:58] <zeeshan> im not sure why a lot of eng don't want to get physical :P
[10:09:00] <yasnak> Ah, anyways, bad rant. Sucks to start out saturdays on a bad note :P
[10:09:03] <zeeshan> (sounds sexual)
[10:09:04] <zeeshan> haha
[10:09:21] <yasnak> Eh, whatever gets the excitement level up eh
[10:09:46] <zeeshan> yasnak: heres an example of a silly mistake ive made
[10:09:52] <Roguish> it's definitely a 2 way street. machinists and mechanics don't usually like me either, 'cause I can do pretty much whatever they can, but they usually can't do what I do.
[10:09:56] <zeeshan> and i work with my hands all the time
[10:09:59] <zeeshan> i put in a bolt that couldnt be installed
[10:10:00] <zeeshan> lol
[10:10:06] <zeeshan> sometimes its hard to see in the computer model
[10:10:18] <zeeshan> in real life i woulda known right away
[10:10:29] <zeeshan> haha Roguish
[10:10:37] <yasnak> Tried to use one of those L-Shaped bolts?
[10:10:53] <zeeshan> nah bolt was too long to go in from one direction
[10:11:11] <yasnak> See oyur issues are always like...
[10:12:04] <yasnak> Not like that. More like a 1/4-20 bolt, correct specs. Placed about 0.01" from the wall to tapped major ID. So you end up having the drill/tap walk or just plain break.
[10:12:10] <Roguish> the whole 'communication' thing does work, just gotta break down the walls. OH, same with the mechanical versus the electrical.... every place I've been has been a 'throw it over the wall' to the electrical/controls groupl.
[10:12:27] <yasnak> Things that make you lose hair
[10:13:52] <Roguish> yasnak. ever had anyone cheat on a drawing dimension ? that's when the dimension is edited and the drawing or model is not changed? then the model or drawing file is used for manufacture? you get a heap of expensive scrap.
[10:14:01] <yasnak> OMG
[10:14:11] <yasnak> Yes
[10:14:20] <yasnak> haha, this is an everyday issue. They override dims
[10:14:51] <Roguish> first thing I tell my drafters and designers is the cheating dimensions is a firing event.
[10:15:10] <Roguish> how can you be ISO with that?
[10:15:25] <yasnak> So you'd fire over that for real?
[10:15:29] <yasnak> You can't...
[10:15:59] <yasnak> I waste endless time and scrap with that. Its got to the point where I'll get a print but I'll need to check the model I'll be using for surfacing before I even begin programming it.
[10:16:43] <yasnak> Or when they dimmension off of other machined surfaces and never give me a dimmension to the part center or some sort of datum.
[10:16:44] <Roguish> ya know even the threat works pretty good. and explain it in dollars and cents. paying for scrap is just wasteful. lower profit, lower wages.
[10:17:51] <Roguish> above all I always try to get everyone to understand that it is a 'cooperative' thing, not a 'competitive' one.
[10:18:24] <Roguish> a constant effort for sure.
[10:18:31] <yasnak> Sometimes its annoying, as we're somewhat still a mid-size factory. So babysitting someone day in and day out isn't something that can be done while also getting your own stuff done.
[10:18:39] <Roguish> but ya can't give up. never give up.
[10:18:45] <yasnak> Ah at least I'm not alone in this haha.
[10:18:57] <Roguish> dude, not at all.
[10:19:10] <yasnak> Hey man, thats why I'm at the shop on saturdays. Hanging with 1st and 2nd shift guys is somewhat fun.
[10:19:30] <Roguish> that's the ticket.
[10:22:56] <PetefromTn_> Morning linuxCNC
[10:23:03] <archivist> when it is external designers, you have to give the drawings a good looking at and send a barrage of questions
[10:25:50] <archivist> I did get one job, "do what you like"
[10:26:05] <yasnak> We do this all, it just ends up being an issue of project management.
[10:26:14] <tiwake> hey PetefromTn_
[10:26:25] <PetefromTn_> hey tiwake
[10:31:22] <Erant> Is there anything especially wrong with the 600p encoders I see on eBay?
[10:31:32] <Erant> Does a spindle encoder require a Z for example?
[10:31:50] <Tom_itx> zeeshan it should be a prerequisite for all engineers
[10:32:15] <Tom_itx> the bad ones would end up with no fingers and the problem would self solve
[10:32:52] <Roguish> Tom_itx: so how do you really feel?
[10:33:13] <cpresser> he cant feel his fingers :)
[10:33:15] * zeeshan overrides dimension
[10:33:15] <zeeshan> :D
[10:33:30] <Roguish> you're FIRED !!!
[10:33:33] <Tom_itx> i have all my digits and plan to leave this life with them
[10:33:49] <zeeshan> Roguish: its okay
[10:33:54] <zeeshan> if the model is +/- 0.030 thou
[10:34:02] <zeeshan> why do you think holes have clearance in them
[10:34:04] <zeeshan> :D
[10:34:20] <Jymmm> Tom_itx: You can leave with them, not necessarily attached, how about a nice necklace instead?
[10:35:00] <Tom_itx> naw i'm not that sort of freak
[10:35:22] <Jymmm> Tom_itx: Oh, so you're a special kind of freak - gotcha!
[10:35:51] <pcw_home> Erant: spindle encoders need Z ( if used for threading or rigid tapping)
[10:36:05] <archivist> Erant, you need a z for threading
[10:36:20] <PetefromTn_> what sort of freak are ya there tom?
[10:36:28] <yasnak> lol
[10:36:33] <Tom_itx> not all that freakish really
[10:36:41] <tiwake> if I'm redoing all the wiring in my car, what kind of wire do I want to get?
[10:36:46] <yasnak> Plus side is...I actually still have all my fingers. Boss just recently tried to mill his off though
[10:36:47] <Tom_itx> copper
[10:36:54] <Tom_itx> with teflon jacket
[10:37:01] <yasnak> Who knew an endmill tends to *grab* metal..an
[10:37:05] <yasnak> and flesh :P
[10:37:06] <PetefromTn_> sorta like annoying people don't really know how annoying they really are ;)
[10:37:09] <tiwake> probably stranded core?
[10:37:20] <zeeshan> pe
[10:37:24] <zeeshan> PetefromTn_: i dont know how annoying i am
[10:37:31] <Tom_itx> PetefromTn_ not pointing any fingers are ya? :)
[10:37:36] <Tom_itx> err do you still have em..
[10:37:37] <tiwake> zeeshan: helps if you press tab ;)
[10:37:42] <Jymmm> Tom_itx: https://www.youtube.com/watch?feature=player_detailpage&v=QYHxGBH6o4M#t=74
[10:37:44] <zeeshan> :-(
[10:37:46] <tiwake> :D
[10:37:47] <PetefromTn_> zeeshan That much is abundantly clear ;)
[10:38:15] <zeeshan> it took 9 months but i sold the fanuc spindle drive on ebay
[10:38:18] * Tom_itx decides not to click on Jymmm's offerings
[10:38:21] <zeeshan> more like 5 months :P
[10:38:33] <PetefromTn_> a safe assumption
[10:38:43] <Erant> Ah. Z it is then. They're slightly more expensive, but they also look to be better built
[10:39:27] <archivist> Erant, number of slots matters if you are going to use a parallel port
[10:39:40] <Erant> It'll be hooked up to a 7i78
[10:39:55] <archivist> then you can use almost any
[10:40:41] <Erant> I intend on bypassing the controller in there right now, feeding the encoder to the 7i78 and using the spindle 'pot' as the speed control.
[10:41:07] <Erant> Which closes the loop over what is there currently (just speed from the hall sensors, fed to an ATMega)
[10:46:07] <tiwake> CaptHindsight: poke about getting/buying some dye :3
[10:47:07] <Erant> Interesting, there's some pretty cheap OMRON ones that are 2000p/r
[10:47:30] <Erant> $25 shipped from China, A B Z.
[10:48:50] <Erant> The only thing I'm a little concerned about is the low Vref for the torque control. 6.25v
[10:49:56] <pcw_home> high resolution is not very important for a spindle encoder
[10:49:58] <pcw_home> (and lower res encoders are less fussy mechanically)
[10:50:57] <CaptHindsight> but I want my 1 arc second of res :)
[10:51:12] <Erant> pcw_home: I know, that's just one of the cheaper ones...
[10:51:38] <Erant> Probably knock-offs though
[10:52:16] <pcw_home> really cheap, wonder what they look like inside
[10:53:40] <archivist> I wonder if some of the really cheap are non optical
[10:54:04] <Erant> Just like a resistive thing?
[10:54:12] <archivist> capacitive
[10:55:14] <Erant> ah
[10:56:19] <archivist> like in the joint of these http://www.ebay.co.uk/itm/Excel-Genuine-Folding-Digital-Display-Angle-Finder-Steel-Rule-200mm-Like-DAR200-/181852654192
[10:57:57] <archivist> but I think it is more likely that technology will be in the non Z encoders
[11:02:31] <Erant> They're all knockoffs for sure. All of them have different line count.
[11:02:52] <Erant> None of them advertise the actual Omron line count :P
[11:03:17] <archivist> I have one of the real cheap non Z 100 line encoders, seems ok
[11:03:48] <Erant> Oh, I wasn't saying I was going to buy an actual Omron one.
[11:03:54] <Erant> Just that they need to try a little harder.
[11:09:44] <gregcnc> Is setting up spindle encoder feedback different for a back tool lathe? There is a forum thread talking about it.
[11:18:45] <zeeshan> you know youre a bit mental
[11:18:55] <zeeshan> when you start using cad to model shipping crates
[11:18:59] <zeeshan> http://i.imgur.com/zCF7u60.png
[11:19:00] <zeeshan> :D
[11:21:20] <gregcnc> agree, but it's not a serious condition unless you tolerance it.
[11:21:32] <archivist> some sellers are a bit mental http://www.ebay.co.uk/itm/291659096054
[11:23:35] <zeeshan> lol
[11:23:42] <zeeshan> archivist: lol
[11:23:48] <zeeshan> archivist: btw i inquired about the vial
[11:23:49] <zeeshan> its 250 usd.
[11:24:34] <archivist> ouch
[11:25:27] <archivist> cheaper to buy a level and take the vial out
[11:25:31] <zeeshan> yes
[11:33:32] <Tom_itx> another earthquake just now
[11:34:30] <zeeshan> WHERE
[11:34:31] <zeeshan> er
[11:34:31] <zeeshan> caps
[11:34:37] <Tom_itx> 5.4
[11:34:46] <Tom_itx> 9KM SE of pawnee Ok
[11:35:49] <Tom_itx> wait.. that one isn't reported yet
[11:39:26] <CaptHindsight> a Linux IDE for STM32's http://linuxgizmos.com/st-releases-free-linux-ide-for-its-stm32-mcus/
[11:39:43] <CaptHindsight> uses Eclipse and I haven't seen the libs yet
[11:40:10] <Duc> afternoon
[11:44:24] <CaptHindsight> $49 Orange PI Plus with 2GB ram http://www.aliexpress.com/store/product/Orange-Pi-Plus-2-H3-Quad-Core-1-6GHZ-2GB-RAM-4K-Open-source-development-board/1553371_32516755321.html
[11:46:31] <CaptHindsight> what is the current price of an Intel mini-itx with 2GB ddr?
[11:47:04] <Erant> k, going for the 'Omron' encoder. Just gotta figure out the best way of attaching it to the spindle.
[11:48:06] <Duc> what kind of spindle
[11:49:07] <Erant> It's my Sieg SX1P. So it's an existing integrated thing. But when I opened it up I noticed the back of the main spindle rod has a little hole.
[11:49:22] <Erant> So I just gotta make/turn/mill something to center in that hole.
[11:49:40] <Erant> And then probably some superglue.
[11:49:45] <Duc> then knurl it with a punch a little
[11:49:49] <Duc> hold its perfect
[11:50:01] <Erant> Sure
[11:50:23] <Erant> There's actually three screw holes around the spindle already for some reason.
[11:50:23] <Duc> thats how mine is held into the bridgeport spindle
[11:50:53] <Duc> turn to slip fit then knurled it with a pointed punch
[11:53:17] <Erant> Hoping to get some better response out of this.
[11:53:45] <Erant> Currently I can hear the thing bog down on engagement with material, and it takes it a good second and a half to realize it.
[11:54:24] <Duc> what are you looking to use the encoder for
[11:54:35] <CaptHindsight> I thought that Intel kept the J1800 and 1900 boards under $50
[11:55:29] <Erant> Duc: So I'm wanting to control my spindle with LinuxCNC. Technically I can do that now with just an open-loop spindle 'pot'.
[11:55:50] <Erant> But I think I'd rather have LinuxCNC do the entire control action.
[11:57:05] <Duc> ah
[11:57:39] <Erant> So adding an encoder to the spindle, bypassing the existing speed control and wiring the torque signal to the Mesa.
[11:57:48] <Duc> I use a encoder just to verify my speed and scale are correct
[11:59:04] <Erant> And this gives me the option of doing rigid tapping in the future, if I so choose.
[12:00:02] <Duc> I have yet to use mine for that but one day
[12:00:44] <Erant> Yeah, I have to get special collets, so we'll see.
[12:01:20] <Erant> Maybe if I torque up my drill chuck real tight :P
[12:02:06] <Erant> I'd get #8, #10 collets though. I use those a bunch
[12:05:15] <Duc> I think I used a encoder from automation direct for mine
[12:07:18] <Tom_itx> 5.1 near Fairview Ok
[12:11:40] <Erant> Tom_itx: Damn. That's a shaker.
[12:12:04] <Erant> I live in the Bay Area, and our last one was something like that.
[12:12:59] <Erant> Duc: I'm taking a chance on some Chinese ones.
[12:13:29] <Erant> They cloned an Omron one
[12:14:52] <gregcnc> the CUI encoders are capacitve $25. I just installed on om my lathe spindle.
[12:16:26] <gregcnc> I have the spindle running both ways, but need to set up a spindle meter.
[12:17:13] <gregcnc> which brings the question are there any ready to go lathe gui?
[12:18:14] <Erant> gregcnc: CUI?
[12:21:10] <gregcnc> http://www.cui.com/catalog/components/encoders $25 for cmos output
[12:22:08] <Erant> Ah.
[12:22:20] <Erant> Yeah, these are going to be a toss-up: http://www.ebay.com/itm/Omron-Rotary-Encoder-E6B2-CWZ6C-1000P-R-E6B2CWZ6C-xhg04-/321818761803
[12:22:34] <Erant> They're 100% fake, just wonder how fake.
[12:23:32] <CaptHindsight> they should be stating back to work next week
[12:23:41] <CaptHindsight> stating/starting
[12:23:51] <Erant> Yep
[12:23:55] <CaptHindsight> for $20 I'd order one to try
[12:24:05] <Erant> Which is what I did
[12:24:20] <Erant> It's just the spindle.
[12:24:21] <gregcnc> wha'ts a real one cost?
[12:24:31] <Erant> $100+?
[12:25:08] <Erant> The cheapest one in the US is $50 shipped, used.
[12:25:53] <Erant> And then there's this crufty one for $60 + shipping: http://www.ebay.com/itm/Omron-E6B2-CWZ6C-Rotary-Incremental-Encoder-T43050-/351652099600
[12:26:16] <Erant> Yeah, they're about $120 new.
[12:26:17] <CaptHindsight> unless Omron makes them in China and these are 4th shift production
[12:26:43] <Erant> Could be, could be. Unlikely.
[12:26:50] <CaptHindsight> sold out the back door, no warranty
[12:26:58] <Erant> China usually just picks a thing to copy and then they do it. A lot.
[12:27:12] <CaptHindsight> they might also be right from Omron but sold to a high volume user
[12:27:20] <Erant> I have a VC99 for example
[12:27:21] <Erant> http://www.ebay.com/itm/VC99-Auto-Range-DMM-AC-DC-Voltmeter-Capacitance-Resistance-Digital-Multimeter-/180933198869
[12:27:29] <Erant> See any resemblance to a certain well-known brand?
[12:27:33] <CaptHindsight> that how we get lots of parts at the 1 million piece price + 1-2%
[12:27:53] <gregcnc> how does that seller keep track of the fake and real ones, some are 200+USD?
[12:28:38] <CaptHindsight> looks like a genuine HungShort
[12:33:41] <Erant> Ordered. I'll let y'all know if it works.
[12:34:20] <Erant> Now I just need to find a little graphical LCD to fit where the old one used to go...
[12:34:31] <Erant> Because I like overdoing things.
[12:34:58] <Erant> Might design a new face plate...
[12:43:04] <Sync> Erant: I'm actually not too positive on them being fake
[12:43:25] <Sync> I mean, they are 1000 line encoders, that stuff must be cheap to make now
[12:46:19] <Duc_mobile> really cheap
[12:49:38] <zeeshan> a lot of omron stuff seems to be made in china
[12:49:43] <zeeshan> just like any other company :P
[12:50:30] <Erant> We'll see.
[12:50:37] <Erant> I can probably tell from the label.
[12:50:54] <zeeshan> carrier moved their plant to mexio
[12:50:56] <zeeshan> lol
[12:51:34] <Erant> Mexico and Brazil are the new places.
[12:51:40] <Erant> Foxconn has a factory in Brazil now.
[12:51:52] <zeeshan> let someone else do the shitty work :)
[12:52:06] <zeeshan> economics 101
[12:52:09] <Erant> ;)
[12:52:11] <CaptHindsight> zeeshan: they wanted to keep the same people who were making the units so they moved to mexico :p
[12:52:23] <zeeshan> lol capt
[12:52:44] <zeeshan> i just take all this news as
[12:53:02] <zeeshan> "if you have skills someone whos cheaper has, they will win"
[12:53:39] <CaptHindsight> true, if you keep on rewarding selfish people
[12:53:46] <zeeshan> it boggles my mind that some of these workers who are responsible for mindless work
[12:53:49] <zeeshan> get paid so much
[12:53:54] <CaptHindsight> it's not rocket science
[12:54:04] <CaptHindsight> and these aren't laws of nature
[12:54:16] <zeeshan> they kinda care
[12:54:17] <zeeshan> *are
[12:54:21] <zeeshan> the fittest win
[12:54:31] <zeeshan> otherwise we'd still be monkeys :)
[12:54:37] <zeeshan> in my case i still am .. hairy hands
[12:54:38] <zeeshan> :[
[12:55:10] <CaptHindsight> it's attitude, not physical laws
[12:56:00] <CaptHindsight> some people don't know the difference
[12:59:54] <zeeshan> as ignorant as my comment is about to be
[13:00:02] <zeeshan> i won't be buying carrier products :)
[13:00:23] <zeeshan> cause they make shitty a/c's!
[13:04:45] <yasnak> Our AC units tend to double as mist collectors
[13:05:08] <yasnak> Feel the pain of the HVAC guys every month when they do maintence, we swap filters weekly
[13:11:28] <witnit> yasnak: like yasnac the robot controller or a different reference?
[13:13:02] <yasnak> ;)
[13:13:05] <yasnak> yes
[13:13:11] <yasnak> or yaskawa's old controller
[13:13:41] <witnit> I just hooked mine up to my mesa card :)
[13:13:50] <CaptHindsight> I only buy AC units that are certified organic
[13:15:02] <yasnak> we still have their old yaskawa siemens controls on our swiss
[13:15:04] <gregcnc> capthindsight i have to endure an afternoon of those kind of people today
[13:15:13] <yasnak> takes a different kind of "i hate life" to use them :P
[13:18:19] <witnit> Im pretty sure with the comminications manual and a handful of wire you can pass anything you want to the controller with something like a 5i25
[13:18:53] <yasnak> we've got the good old 830D
[13:19:25] <witnit> im not familiar enough with them, I just got the one machine yasnac ERC, K10S
[13:24:38] <witnit> yasnak: http://galvanist.com/post/99533576291/giving-your-ancient-robot-arm-a-storage-upgrade
[13:25:15] <witnit> This worked well for me
[13:28:18] <yasnak> ill take a look at it in a bit
[13:28:36] <yasnak> having issues with WSUS on the server, afraid i may have fubar'd it
[13:44:31] * skunkworks currently is working on replacing the yasnak conttrol
[13:47:29] <PetefromTn_> Well so far I got the upstairs latrine fixed, the outlet in the bathroom replaced with a nice new fancy paddle three way one and put GFCI's everywhere there is a sink, now onto the replacing any missing or cracked outlet covers and installing the overflow safety on the hot water heater... Then after lunch it is back onto working on the new kitchen cabinet doors!! ;) I am tired just typing that
[13:49:20] <PetefromTn_> Wish I was working on the CNC lathe instead of all of this SHTUFF!!
[14:04:49] <witnit> skunkworks: which controller?
[14:05:02] <Deejay> mojn
[14:05:07] <witnit> Moin!
[14:05:16] <Deejay> ha! :-)
[14:05:19] <witnit> :)
[14:12:19] <PetefromTn_> http://www.msn.com/en-au/sport/motorsport/watch-this-mclaren-650s-gt3-break-the-lap-record-at-bathurst/ar-BBprrow?li=AAgfYrC&ocid=mailsignout Man that is an insane lap..
[14:12:58] <witnit> PetefromTn_: that doesnt look like cabinet doors
[14:15:19] <skunkworks> mx1
[14:15:43] <skunkworks> i think
[14:16:09] <PetefromTn_> witnit I know man I needed to take a break
[14:16:31] <PetefromTn_> can you believe those curves on that track? Uphill downhill balls out racing... INSANE!!
[14:17:13] <PetefromTn_> I thought the Chicane at Laguna was steep and twisted
[14:17:40] <witnit> are you doing your own kinematics and software or just passing commands so you can still use the old pendant for programming the circles, linear, weaving ect
[14:18:17] <witnit> PetefromTn_: i think i payed more attention to the buttons on the steering wheel than the track. that cockpit is so nice
[14:18:56] <PetefromTn_> well yeah....McClaren!
[14:20:27] <skunkworks> me?
[14:20:39] <skunkworks> it is on a matsurra 3 axis machine
[14:21:52] <skunkworks> I do have a puma arm that is on the 20 year plan
[14:23:29] <Jymmm> skunkworks: 20 years till it turns into a pile of rust powder?
[14:24:11] <skunkworks> aluminum'
[14:24:19] <XXCoder> restore one pary a month?
[14:24:20] <XXCoder> part
[14:24:36] <XXCoder> alum do rust ya know
[14:25:27] <skunkworks> it is not high on the priority list
[14:25:42] <PetefromTn_> http://ringbrothers.com/1971_pantera_adrnln WOW
[14:28:21] <CaptHindsight> PetefromTn_: you'll soon be basking in sunny Florida
[14:28:36] <PetefromTn_> hopefully anyway
[14:28:51] <CaptHindsight> at least they didn't ask you to shingle the roof or something tedious
[14:29:04] <PetefromTn_> well I gotta finish the kitchen cabinets
[14:29:18] <PetefromTn_> and finish tiling the floor in the downstairs bathroom/laundry room
[14:29:26] <PetefromTn_> get it grouted etc.
[14:29:46] <PetefromTn_> I gotta install all the base trim and door trim we removed to fix dents and dings
[14:30:00] <PetefromTn_> and a small laundry list of small items like this mornings stuff
[14:30:11] <CaptHindsight> tile cutting can get a bit messy but still pretty simple for a small room
[14:30:30] <CaptHindsight> in a few days you'll be done
[14:30:38] <PetefromTn_> actually I mostly have it all cut when I had the tile saw
[14:30:49] <PetefromTn_> just gotta stick it down now
[14:48:12] <aventtini6> hello agen
[14:48:15] <aventtini6> guys
[14:48:17] <aventtini6> https://www.youtube.com/watch?v=5IPrGa3AAUo
[14:48:42] <aventtini6> i tested and tested whit no success
[14:48:49] <aventtini6> whats so ever on 2.7
[14:49:10] <aventtini6> can imagin whats wrong
[14:50:02] <aventtini6> i test te machine on DAC
[14:50:07] <aventtini6> it works perfect
[14:50:18] <aventtini6> encoder scale
[14:50:30] <aventtini6> pwm Volts
[14:51:12] <aventtini6> all its ok
[14:51:40] <aventtini6> when i start linuxcnc whit minimum settigs machine gos wild
[14:52:11] <CaptHindsight> goes wild = what exactly?
[14:52:30] <aventtini6> i give + 1mm
[14:52:38] <aventtini6> it gos 10 20
[14:53:13] <aventtini6> i mesure with gaudge scale is corect on the encoder
[14:53:37] <aventtini6> then scale on the pwm is 10v on a scale of 10
[14:53:57] <CaptHindsight> the machine moves 10 - 20 or the position on the screen changes by 10-20?
[14:54:34] <aventtini6> no on the dro and also on gaudge
[14:55:43] <aventtini6> i test the speed and acc
[14:55:45] <aventtini6> same shit
[14:55:54] <CaptHindsight> what happens when you just run a SIM?
[14:56:07] <CaptHindsight> are you using steppers?
[14:56:11] <aventtini6> servo
[14:56:32] <CaptHindsight> servos need tuning
[14:56:39] <aventtini6> :)))
[14:56:45] <aventtini6> sure the need
[14:56:52] <aventtini6> thats the ugly part
[14:57:03] <aventtini6> i cant tune and i dont know whiy
[14:57:05] <aventtini6> why
[14:57:40] <CaptHindsight> http://gnipsel.com/linuxcnc/tuning/servo.html
[14:58:18] <aventtini6> i have done 6 machine whit 2.6
[14:58:23] <aventtini6> no problem
[14:58:58] <aventtini6> i have done this alot
[14:59:01] <CaptHindsight> so where are you stuck? at what exact point of the servo tuning?
[14:59:02] <aventtini6> but not whit 2.7
[14:59:16] <aventtini6> i no stuck
[14:59:21] <aventtini6> it cant tune
[14:59:35] <aventtini6> i made the P to 800000
[14:59:42] <aventtini6> no oscilation
[15:00:15] <aventtini6> the only way that machine is moving as my settings is if i put the FF0 to 1
[15:01:15] <CaptHindsight> have you gone through the first steps and manually moved the encoders a known amount to see if the SCALE is set properly?
[15:01:17] <witnit> aventtini6: like your output scale?
[15:01:21] <aventtini6> yes
[15:01:30] <aventtini6> yes i mesure 10v
[15:01:45] <aventtini6> dac is 1 , mesure is 1
[15:01:56] <witnit> can we see your ini?
[15:02:14] <aventtini6> its on youtube
[15:02:20] <aventtini6> sorry i home
[15:02:27] <aventtini6> my head give up
[15:02:53] <CaptHindsight> I miss the simplest of things at times when I'm tired
[15:03:14] <CaptHindsight> post your configs when you get a chance
[15:03:24] <aventtini6> me to but not on 3 machines
[15:03:33] <aventtini6> and 2.6 works perfect
[15:03:34] <CaptHindsight> it's like proof reading your own writing
[15:03:54] <aventtini6> wiring is perfect
[15:04:18] <CaptHindsight> maybe
[15:04:34] <witnit> well regardless of your scale if I understand correctly even if your motor is tuned poorly nothing should lose rate of travel per encoder reading
[15:04:37] <aventtini6> 100%
[15:04:54] <aventtini6> yes
[15:05:10] <aventtini6> but whit if i give 1 mm it gos 20 30 mm
[15:05:11] <witnit> so manually if you move your axis it is losing accuracy
[15:05:20] <CaptHindsight> we can probably rule out a curse, magic, gremlins etc
[15:05:36] <aventtini6> no its not about accuracy
[15:05:46] <aventtini6> its like a delay
[15:05:58] <witnit> okay so if you manually rotate your motor/encoder to 1 mm it still reads 1mm on screen?
[15:06:04] <aventtini6> see in the video how is the machine moving on test DAC
[15:06:09] <aventtini6> yes
[15:06:33] <CaptHindsight> I was motion sick 1 minute into it
[15:06:46] <aventtini6> yes
[15:06:48] <aventtini6> sorry
[15:06:54] <aventtini6> i was verry furrios
[15:06:56] <aventtini6> :)))
[15:06:58] <CaptHindsight> what time is it at?
[15:08:12] <aventtini6> 5.22
[15:09:26] <aventtini6> it moves like a charm
[15:09:55] <witnit> aventtini6: if I am reading your screen correctly you moved the axis in the + direction and the axis jumped to a - direction
[15:10:49] <aventtini6> i have also tested that problem to
[15:11:29] <aventtini6> encoders are liniar HH
[15:11:55] <aventtini6> i have tested whit -1000
[15:12:03] <aventtini6> same result
[15:12:19] <aventtini6> maybe is a torque drive?
[15:12:35] <aventtini6> why its working on 2.6
[15:12:57] <witnit> aventtini6: you have jacked your ferror way up and then flopped your encoder A/B signals (just a guess!)
[15:13:07] <aventtini6> yes
[15:13:11] <aventtini6> 50mm
[15:13:19] <aventtini6> on
[15:13:27] <aventtini6> just to test the movment
[15:13:31] <witnit> what happens when you flop your encoder signals?
[15:13:42] <aventtini6> change the channels ?
[15:13:46] <aventtini6> o mean ?
[15:13:54] <aventtini6> you mean ?
[15:14:18] <witnit> just the encoder signal wires A and B
[15:14:29] <aventtini6> that i did not test
[15:14:42] <witnit> I would suspect your A and B are backwards
[15:14:58] <aventtini6> but why it works on 2.6 and DAC?
[15:15:03] <pcw_home> There are no significant differences between 2.6 and 2.7
[15:15:28] <aventtini6> drives are bosch tacho drive
[15:15:30] <pcw_home> you should use your 2.6 config files on the 2.7 version
[15:15:49] <pcw_home> (if they worked)
[15:16:04] <aventtini6> i working for 6 months
[15:16:10] <aventtini6> whit 2.6
[15:16:23] <aventtini6> pcw there is any 6i25
[15:16:27] <pcw_home> There is no difference
[15:17:01] <pcw_home> I'll bet you have changed you config files.
[15:17:11] <aventtini6> for example the 2.6 has ff0=0 and P=2
[15:17:17] <aventtini6> no
[15:17:24] <aventtini6> fresh install
[15:17:31] <pcw_home> THERE IS NO DIFFERENCE
[15:17:44] <pcw_home> use your old config files
[15:18:19] <aventtini6> i will test in the morning
[15:18:35] <aventtini6> drives has a 5v sw and a 10sw
[15:18:47] <witnit> is this a new build altogether or did you simply just install a 2.7 on a machine which used to work?
[15:19:07] <aventtini6> its a machine that worked
[15:19:36] <witnit> then you should be able to do as PCW has said, simply copy over your config files from 2.6
[15:19:39] <aventtini6> pcw
[15:19:54] <aventtini6> why its working on DAC test mode?
[15:20:48] <aventtini6> see video on 1.22
[15:21:02] <aventtini6> minute
[15:25:33] <aventtini6> all the ideea is cmomming that the scale of pwm is now right
[15:26:27] <aventtini6> if the encoder scale is ok then 1 mm and it give 20m or more it means the SW is large scale
[15:26:32] <witnit> It seems you may want to learn why your voltage is forcing the motor in a negative direction when you press the + button.
[15:27:19] <aventtini6> its possible you are right
[15:27:29] <aventtini6> if the channels are wrong
[15:27:34] <aventtini6> on the board
[15:27:47] <witnit> well it cannot be wrong if this system used to work
[15:28:14] <witnit> the only way it would be wrong is if your hardware differs or your config files (as far as i know)
[15:29:09] <aventtini6> i did see on the DAC now
[15:29:28] <aventtini6> i press + and it shows - on encoder count
[15:29:50] <witnit> maybe your old config files had something like a -10 output scale and you forgot you adjusted it?
[15:29:59] <aventtini6> it works on dac because is a open loop right
[15:30:05] <aventtini6> no
[15:30:09] <aventtini6> this must bee
[15:30:26] <aventtini6> but why it dont make a runway
[15:30:37] <aventtini6> sw is - encoder is +
[15:30:44] <aventtini6> it must make a runnay
[15:34:30] <witnit> Its hard to say without comparing your old configs with your new ones
[15:36:16] <aventtini6> hmmm
[15:37:46] <aventtini6> im right about the DAC test mode
[15:37:51] <aventtini6> its a open loop
[15:38:20] <aventtini6> that is good explain why its this working
[15:40:27] <aventtini6> aaaa
[15:40:32] <aventtini6> good point
[15:40:35] <aventtini6> your the man
[15:41:06] <aventtini6> when i give it 1 mm it drifts the ff eror to 22mm or more
[15:45:48] <aventtini6> has anyone seen drive with 5v SW?
[15:45:54] <aventtini6> and 10V?
[15:46:04] <pcw_home> You should have just used your old configs (and no changes to the hardware/wiring)
[15:46:05] <pcw_home> anything else makes a lot of work
[15:46:19] <aventtini6> yes thats the fun part
[15:46:20] <aventtini6> :D
[15:46:43] <aventtini6> first i use my head to solve the problem
[15:46:55] <aventtini6> then i take the simple way
[15:47:13] <aventtini6> this is the way i have learn linuxcnc
[15:47:27] <aventtini6> whit 2.6 i can retorfit the all machine in 2 days max
[15:47:55] <aventtini6> but because of the traj im lost a lot of time on milling
[15:48:11] <aventtini6> because it brakes on corners
[15:48:39] <aventtini6> i have got a itx i dont know the exact model from junckyard
[15:49:00] <aventtini6> and im getting latecny no more then 3000
[15:49:45] <aventtini6> and the machine moves like a raket
[15:50:11] <aventtini6> more then 14000 on a dell pc i did not get a good retorfit
[15:50:54] <pcw_home> unless you are using software stepping, latency is relatively unimportant
[15:51:59] <aventtini6> yes
[15:52:05] <pcw_home> 14000 is fine (even 250000 = 0.25 ms is probably OK with the right setup )
[15:52:33] <aventtini6> why do you produce the 6i25
[15:53:06] <aventtini6> i mean as technical diff
[15:53:12] <aventtini6> on a 5i25
[15:53:38] <pcw_home> because some Motherboards dont have PCI slots
[15:54:19] <pcw_home> ( and just have PCIE )
[15:55:05] <boboss-> What is the function of the enableĀ  on the Driver?
[15:55:10] <aventtini6> it only a pci to pci express differance
[15:55:19] <aventtini6> machine on
[15:55:26] <aventtini6> plus a 3 way relay
[15:55:55] <Deejay> gn8
[15:57:10] <aventtini6> what the differance on machine on and enable ?
[15:57:34] <aventtini6> i need to use a pin on enable insted on machine on?
[15:59:43] <aventtini6> i was so tierd i did no see the encoder
[15:59:56] <aventtini6> is on - and command is on +
[16:02:32] <ve7it> cradek, you around?
[16:14:12] <ve7it> cradek, I remember some chatter about some of the previous iso mages not using PAE. Turns out I have a machine that doesnt support PAE
[16:16:38] <ve7it> cradek, and I need an iso image for it. All the distros since Ubuntu 10.04 have PAE turned on.... I did get one of the old original emc2 10.04 isos to run fine, but I think there was something
[16:18:06] <ve7it> cradek, possibly the linuxcnc 2.6 iso release that everyone thought had PAE tuned on and it didnt. Any ideas?
[16:20:32] <aventtini6> pcw i has a question of logics that i dot have a clear image . SW is + - encoder has AA+ 5v BB-- and encoder scale -1000
[16:21:24] <aventtini6> if i revers the AA BB
[16:22:08] <aventtini6> its a differance on the encoder scale -1000
[16:31:32] <pcw_home> if you reverse A/B you would need to reverse the encoder scale to keep things the way they were
[16:34:24] <pcw_home> normally for servo setup you do things in this order:
[16:34:25] <pcw_home> Get DRO reading right with encoder scale (scale and direction correct)
[16:34:27] <pcw_home> check if feedback is correct (holds position and doesn't run away)
[16:34:28] <pcw_home> if not, reverse output scale
[16:57:33] <aventtini6> 10x
[18:09:41] <_methods> hahah just got back from watching deadpool
[18:09:44] <_methods> movie was hilarious
[18:11:00] <witnit> if betty white gave it her approval im game
[18:11:42] <_methods> i haven't laughed that much at comedies that are supposed to be funny
[18:12:01] <_methods> it was just pretty much constant smart ass wisecracks
[18:12:02] <witnit> thats the secret to a good comedy ;)
[18:12:44] <_methods> well they nailed it on this one
[18:12:52] <XXCoder> _methods: yeah comedies dont seem to remember how to be funny
[18:12:59] <XXCoder> in least, not without wisecracks
[18:13:09] <pink_vampire> morning
[18:13:39] <XXCoder> hey pink_vampire
[18:13:58] <XXCoder> whew spent hours building statue and its not done. ordering more parts lol
[18:14:16] <XXCoder> thats risk of modification of design from orginial
[18:15:20] <pink_vampire> XXCoder: what do you mean?
[18:15:31] <XXCoder> oh sorry was wrong channel lol
[18:15:35] <XXCoder> its a lego statue
[18:15:45] <XXCoder> http://alpha.bricklink.com/pages/clone/catalogitem.page?S=3724-1#T=P
[18:17:14] <DaViruz> there's a lego channel?
[18:17:22] <chris_99> someone should make a CNC lego assembly device ;)
[18:17:23] <pink_vampire> where??
[18:17:35] <XXCoder> DaViruz: not on this irc server
[18:17:40] <DaViruz> oh.
[18:17:56] <XXCoder> I use single client for total of 4 irc server connections though
[18:18:00] <XXCoder> just forgot to switch
[18:18:11] <XXCoder> chris_99: someone did
[18:18:13] <DaViruz> considering having kids just to be able to legitimately play with legos again!
[18:18:13] <XXCoder> out of lego.
[18:18:26] <pink_vampire> I'm stuck with coding.
[18:18:29] <XXCoder> chris_99: lego cnc that build lego
[18:18:38] <chris_99> oooh will have to find that
[18:18:40] <XXCoder> heck someone made a lego lathe
[18:18:48] <XXCoder> though it dont mill lego abs LOL
[18:19:11] <XXCoder> DaViruz: I dont have kids. dont care. lol
[18:19:27] <chris_99> do you mean, it 'cut' lego shapes out of plastic, or.. that it somehow spewed out bricks and assembled them
[18:19:31] <DaViruz> me neither, on both counts really :)
[18:19:45] <Lowridah> any of you guys see this super ghetto 4th axis mod for routers
[18:19:46] <Lowridah> http://www.cncsharktalk.com/viewtopic.php?f=12&t=1521
[18:19:49] <XXCoder> chris_99: in case of lathe, it cuts foam. there is machine that builds though
[18:20:03] <pink_vampire> I think for just work with the regular bricks, it shuld be easy..
[18:20:13] <Lowridah> def one of those 'now why didn't i think of that' things
[18:20:27] <XXCoder> Lowridah: lol that is weird
[18:20:31] <XXCoder> working though
[18:20:45] <XXCoder> fairly loose and not very precise but hey for some uses its just fine.
[18:20:49] <pink_vampire> WTF is that.
[18:21:05] <Lowridah> i wouldn't do it myself but it's pretty neat
[18:21:40] <XXCoder> chris_99: lego mill lol missed that one http://www.makermasters.com/diy-lego-3d-cnc-milling-machine
[18:22:05] <chris_99> hehe
[18:23:04] <DaViruz> reminds me of the plotter lego offered way back
[18:23:22] <DaViruz> http://smg.photobucket.com/user/alexisbad/media/8094.jpg.html
[18:24:23] <chris_99> haha this is exactly what i was thinking of - http://www.wired.com/2010/10/legobot/ (sort of a lego printer)
[18:24:55] <XXCoder> lol yep
[18:25:11] <XXCoder> wish I had it, save time on building that ragon :P
[18:25:15] <XXCoder> dragon
[18:25:27] <chris_99> heh
[18:25:33] <Kevin`> are there any better value low end cnc mills than these? http://www.omiocnc.com/x6-2200l-3a/
[18:26:01] <XXCoder> thats just rebuild from aliexpress I bet
[18:26:11] <XXCoder> you can buy direct but then you gonna fix some issues
[18:28:42] <Kevin`> I wouldn't mind redoing electronics a little.. probably have to for at least that usb card since it's mach-only, but I don't want to have to work around mechanical problems
[18:30:17] <XXCoder> my recommand is look at aliexpress foe similiar machines
[18:30:23] <XXCoder> and see if its worth it or not
[18:30:38] <XXCoder> I guess its in least $500 less, or more
[18:30:43] <Kevin`> people aren't big on vendor reviews for aliexpress
[18:30:55] <XXCoder> though less options than that listed item on way of accessories
[18:34:23] <Kevin`> I can't quickly find any machines on aliexpress with equivalent specs.. similar looking, but different axis and different spindle
[18:36:33] <XXCoder> hmm yeah aliexpress ones isnt too great
[18:36:38] <XXCoder> but an option
[18:54:38] <tiwake> dodododo
[18:55:16] <tiwake> did another batch of anodizing
[18:55:26] <tiwake> my red casswell dye really sucks
[18:56:10] <tiwake> need to get a deburring tank too
[20:11:08] <zeeshan> http://i.imgur.com/Pd2fL0i.jpg
[20:11:09] <zeeshan> hoooray
[20:11:13] <zeeshan> no more plastic bag cover
[20:13:23] <XXCoder> nice
[20:13:36] <XXCoder> man your shop has changed a lot since your first inital pictures
[20:13:45] <zeeshan> hehe
[20:30:13] <Erant> If I want ease of machining, should I use O-1 or W-1?
[20:31:41] <XXCoder> w-40 heh
[20:31:54] <XXCoder> honestly not too sure what you mean by "ease of machining"
[20:32:44] <Erant> Machinability. I'm going to turn some rod down in my mill, so.
[20:33:11] <XXCoder> ahh w-40 can definitely work for that but not too sure if it is best way to do so.
[20:33:34] <XXCoder> just go to car tools store and grab few cans of wd-40
[20:33:54] <XXCoder> though there is non-spraying variant that you can add to sprayer
[20:33:59] <XXCoder> better for envorment
[20:35:10] <Erant> I meant O1 or W1 steel.
[20:35:22] <Erant> O1 being drill rod, basically.
[20:35:45] <Erant> I seem to recall O1 having better machinability than W1.
[20:35:46] <XXCoder> ahh misunderstood you
[20:36:00] <XXCoder> I dont know much about materials unfortunately
[20:36:30] <Erant> Me neither, just seem to remember something along those lines from a YouTube video.
[20:37:41] <Erant> Going to take some drill rod and see how well my mill works as a lathe :)
[20:38:24] <XXCoder> yeah can always buy more stock if needed.
[20:38:49] <Crom> I saw want a mill! 3040 is total crap!!
[20:38:54] <Crom> s/saw/so/
[20:39:05] <XXCoder> Crom: sell me your 3040 lol
[20:39:08] <Erant> I thought about the 3040.
[20:39:12] <XXCoder> cnc router right?
[20:39:20] <Crom> engraver
[20:39:22] <Erant> But it most certainly would not work as a lathe.
[20:39:53] <XXCoder> Erant: one of projects I planned to do is direct mount of wood rod to stepper for 4th axis
[20:39:55] <Crom> it would actually, just not on anything close to iron or even steel
[20:40:27] <XXCoder> it wont be very high accuracy and precision, but it would work for basic tests and maybe basic stuff
[20:41:33] <Crom> I would love to use my headstock back gear to mount a servo motor to, and cnc everything else.
[20:42:03] <Erant> Crom: Well, if I recall correctly, the 3040 has ER11 collets
[20:42:04] <XXCoder> Crom: it works fine on alum?
[20:42:14] <Erant> I'm doing 3/8" drill rod
[20:42:22] <Erant> Which juuust fits in the ER16 collet.
[20:42:37] <Crom> it works on AL, just not fast or good
[20:42:55] <Crom> yes ER11
[20:47:21] <Erant> My SX1P does Al well, and steel ok.
[20:48:00] <Erant> Crom: Right, so I'm using a technique whereby you chuck the material in the collet rather than the tool.
[20:48:19] <Erant> Which allows you to do some limited lathe-style operations
[20:48:57] <Erant> Tool goes in a vice or something. Affixed to the table.
[20:49:41] <Crom> I'm thinking about a Bolton ZX45
[20:53:14] <Crom> and if my VA check is big enough a Grizzly Lathe 11" x 26" G9972Z, which lets me use my Sheldon 4 jaw chuck
[20:54:08] <Crom> tail stock is a MT3, but I can get an adapter to use my MT2 stuff
[20:54:54] <Crom> first thing you do with a G9972Z is add a reverse tumbler
[20:56:21] <Crom> erant, I've done milling with my lathe, though I don't have a collet setup for it, so I hold the end mill in the 4 jaw chuck
[22:25:25] <zeeshan> finally ive learned mastercam better.
[22:25:33] <zeeshan> little to no air cutting with dynamic tool paths
[22:25:37] <zeeshan> makes contouring obsolete
[22:25:44] <zeeshan> http://i.imgur.com/akA0vq9.png
[22:25:45] <zeeshan> example
[22:26:09] <zeeshan> i think hsm works calls it adaptive cleaning
[22:26:55] <zeeshan> absolutely no sharp corners in the tool path
[22:27:06] <zeeshan> (when cutting)
[22:40:24] <Wolf_> nice
[22:42:12] <XXCoder> so it makes parts more smooth or?
[22:42:18] <XXCoder> or just more effecient?
[22:42:45] <zeeshan> more efficient
[22:42:58] <zeeshan> to give you an idea
[22:43:01] <zeeshan> i went from 12ipm
[22:43:04] <zeeshan> to 50 ipm..
[22:43:24] <zeeshan> also sharp corners are very bad for small end mills
[22:43:27] <zeeshan> they snap em :P
[22:43:39] <zeeshan> sharp tool path corners that is
[22:43:46] <zeeshan> cause if yo utry to imagine it
[22:44:07] <zeeshan> at the exact corner, the about 3/4" of the cicumference of the tool makes full contact
[22:44:23] <zeeshan> er..
[22:44:31] <zeeshan> 2 quadrants
[22:44:33] <zeeshan> whatever that is :P
