[01:33:41] <Crom> what did the Tesla car on autodrive say just before it crashed into some trees? "Autocar Akbar!"
[02:00:18] <pink_vampire> any life?
[02:02:17] <archivist> nope all dead
[02:06:07] <pink_vampire> :(
[02:07:17] <pink_vampire> i want to mount the 72v power supply on its side
[02:07:45] <archivist> dont block air flow
[02:07:50] <pink_vampire> so it will take less space in the panel
[02:08:00] <archivist> heat and air flow rises
[02:08:58] <pink_vampire> it is not get even warm..
[02:10:58] <pink_vampire> i made a plate from 1/8" aluminum 2024-t3, so it have some stiffens to it.
[02:11:48] <pink_vampire> the power supply weigh is about 10kg
[02:53:02] <Deejay> moin
[03:43:41] <yasnak> mornin'
[04:51:41] <XXCoder> pink_vampire: im not alive but I can chat anyway
[04:55:30] <pink_vampire> XXCoder: hehe
[04:55:41] <XXCoder> whats up
[04:55:48] <XXCoder> machine working smootholy?
[04:56:23] <pink_vampire> yes, very nice
[04:56:42] <pink_vampire> i just cut the base plate for the power supply
[04:58:00] <pink_vampire> and I'm working on a convert plat to the power supply to mount it side ways,
[04:59:19] <pink_vampire> it's a bit tricky because i want to mount the power supply on the edge of the plate.
[04:59:21] <pink_vampire> XXCoder:
[04:59:40] <XXCoder> yeah though like arch I dont recommand blocking any vents
[04:59:59] <XXCoder> it may be cool but it may be cool because of vents
[05:00:41] <pink_vampire> there is no vents, just huge toroidal transformer
[05:01:26] <XXCoder> ah
[05:01:49] <XXCoder> I cant wait for weekend, so I can print and test my 90 degree 2020 holder :D
[05:02:15] <pink_vampire> picture?
[05:02:27] <XXCoder> dont have one though hold on
[05:03:23] <pink_vampire> ok
[05:04:11] <XXCoder> http://picpaste.com/90degre-MGKpaMMb.png
[05:04:44] <XXCoder> not very complex.
[05:05:47] <archivist> make that in metal
[05:06:09] <XXCoder> yeah that'd be better but dont really have anything that can make that
[05:06:23] <archivist> a drill and some flat
[05:07:03] <archivist> plain angular struts
[05:07:22] <XXCoder> can do that but just did it for challenge for myself
[05:07:24] <XXCoder> design and print
[05:21:57] <pink_vampire> http://i.imgur.com/oTEFVx9.png
[05:22:38] <pink_vampire> the back plate show on the front, and the power supply hiding on the back / right
[05:22:47] <pink_vampire> XXCoder: archivist
[05:23:03] <XXCoder> cool
[05:25:10] <pink_vampire> the plate going to be mount on the back / bottom part of the panel, and the power supply going to stay at the same place and position just mounted to the back plate
[05:50:04] <XXCoder> I wonder how strong grinder I can make with aluminium
[05:53:05] <jthornton> morning
[05:53:24] <XXCoder> hey
[05:53:32] <Deejay> o/
[05:53:32] <XXCoder> grinder isnt right word hmm
[05:53:45] <XXCoder> rotating disks with one tooth
[05:53:48] <XXCoder> breaks stuff
[05:54:17] <archivist> fly cutter?
[05:54:53] <XXCoder> no, its not for making stuff
[05:54:59] <XXCoder> its stacked disks, with spacing
[05:55:08] <XXCoder> each disc single tooth is offset
[05:56:35] <Deejay> for crushing things? :)
[05:56:51] <Deejay> kind of cracking machine?
[05:56:54] <XXCoder> ah figured it
[05:56:55] <XXCoder> shredder
[05:56:57] <XXCoder> thanks dee
[05:56:59] <Deejay> ah
[05:57:00] <Deejay> :)
[05:57:54] <jthornton> what are you shredding?
[05:58:15] <XXCoder> failed prints and stuff (all plastic)
[05:58:30] <XXCoder> I might want to reform em into filiment agai=n
[05:59:29] <Deejay> recycling ftw
[06:00:26] <archivist> I would use steel, lots of force
[06:00:27] <XXCoder> indeed
[06:00:40] <XXCoder> arch but same time im not shredding strong stuff
[06:00:58] <archivist> or plain melting pot with an extrusion hole
[06:01:13] <XXCoder> https://www.dropbox.com/s/t4vd0kmnle4gffp/2016-03-08%2021.32.14.jpg?dl=0
[06:01:15] <jthornton> the real ones use steel with carbide tips
[06:15:40] <jthornton> does repetier save the configuration file somewhere?
[06:16:29] <XXCoder> configure.h but no idea where
[06:21:47] <jthornton> repetier host printer config file
[06:21:47] <jthornton> .mono/registry/CurrentUser/software/repetier/printer/default/values.xml
[06:22:30] <jthornton> XXCoder: did your ramps board come with the sketch installed?
[06:22:45] <XXCoder> no?
[06:24:20] <jthornton> was the marlin sketch on the sd?
[06:24:55] <XXCoder> ah
[06:25:05] <XXCoder> hmm havent really looked on scard lol
[06:25:31] <XXCoder> I know it contains some software like repitier, 3d models for pirinted parts, build docs
[06:25:35] <jthornton> so the printer you just plugged it in and it ran
[06:26:01] <XXCoder> no
[06:26:05] <XXCoder> built it across 3 days
[06:29:21] * Tom_itx sketches a picture of a marlin for JT-Shop
[06:29:27] <jthornton> no, I mean the ramps board you just plugged it in and it worked ie it came preloaded
[06:29:30] <jthornton> lol
[06:30:48] <XXCoder> my sdcard come with those yeah
[06:30:54] <XXCoder> ramps itself I have no idea
[06:32:34] <Tom_itx> https://github.com/MarlinFirmware/Marlin
[06:33:13] <jthornton> yea I have marlin loaded on my ramps 1.4 just messing with it now
[06:33:36] <Tom_itx> there's a configuration.h file you set your stuff in
[06:33:38] <jthornton> the "kit" is due to arrive here Tuesday
[06:33:50] <Tom_itx> heck i though you already had it
[06:33:55] <jthornton> yea, did that some
[06:34:19] <jthornton> just trying to figure out what to back up
[06:34:28] <Tom_itx> iirc there may be a couple others i tweaked slightly
[06:34:51] <jthornton> yea there are two h files you have to tweak
[06:35:27] <Tom_itx> i did hook an encoder up to see how the menus worked with one
[06:35:49] <XXCoder> how do you access files on ramps anyway
[06:37:01] <Tom_itx> probably a menu selection. i can't recall
[06:37:13] <XXCoder> ok
[06:38:13] <jthornton> arduino
[06:39:28] <jthornton> you use arduino to load the marlin program into the Mega 2560 which is under the ramps board
[06:40:47] <Tom_itx> arduino is the windows of avr
[06:43:33] <jthornton> lol
[06:43:54] <XXCoder> still wonder if my CHIP can fake audino lol
[06:44:01] <SIM_CNC> I've got a servo right and left on my Y gantry - frequently the RIGHT servo won't start, so if I do a move it freewheels and then the gecko on that servo faults, because position is lagging behind. Sometimes it starts, sometimes it doesn't - any ideas how I can diagnose/make this problem go away?
[06:44:52] <SIM_CNC> ha, found the problem, easy one :P
[06:45:00] <XXCoder> what was it?
[06:45:30] <SIM_CNC> wire disconnected
[06:45:44] <XXCoder> ah lol in IT biz you check wires and connections first :)
[06:45:56] <SIM_CNC> yup!
[07:20:51] <gonzo_> and in IT, when you find the fault, you try and fix it in software
[07:21:31] <archivist> lazy git :)
[07:22:52] <gonzo_> how many hw eng does it take to change a lightbulb? None, the management have shiopped all the hardware, fis it is SW
[07:23:18] <gonzo_> how many SW eng does it take, etc? None we'll document it
[07:23:36] <archivist> management are now struggling to reimport :)
[07:23:43] <gonzo_> how many doc writers will it take?? None. We will let the forums figure it you
[07:24:06] <gonzo_> out
[07:26:02] <skunkworks> wow - my bearings I ordered from the Netherlands on monday were delivered yesterday.
[08:27:27] <MacGalempsy> the only thing w the arduino is once compliled and sent to the card, there is no decompiling
[08:29:44] <sync> there sure is
[08:32:43] <MacGalempsy> how?
[08:34:25] <jthornton> XXCoder: https://www.amazon.com/HATCHBOX-3D-PLA-1KG1-75-BLK-Filament-Dimensional/dp/B00J0ECR5I/ref=sr_1_3?ie=UTF8&qid=1475154264&sr=8-3&keywords=3d+filament
[08:34:38] <jthornton> $23 a kg free shipping
[08:35:00] <Valen> they are just based on AVR's (or others) there are lots of ways of reading out chips
[08:35:31] <SIM_CNC> if I machine home, work home, bump machine, machine home and then home to the work home (g54) will I be in the same place assuming a perfect machine?
[08:35:51] <SIM_CNC> same place = original work home set point
[08:36:06] <Valen> decap them, put masking tape over the flash area, shine UV in at an angle to get under the mask and erase the fuses then just read it out
[08:36:59] <jthornton> SIM_CNC: you only home the machine then set a G54 or other work offset
[08:37:39] <jthornton> if your home switch is accurate yes you can turn the machine off, on, home and go to the same offset
[08:38:17] <Simonious> jthornton: do I need to remember that offset, or will g54 stay set as long as I don't close linuxCNC?
[08:38:57] <jthornton> http://linuxcnc.org/docs/2.7/html/gcode/overview.html#sub:numbered-parameters
[08:39:08] <jthornton> they are stored in the .var file
[08:39:39] <jthornton> they/the offsets
[08:40:14] <Simonious> they are stored at the time that I set them in linuxCNC using touch off? (sorry for all the questions)
[08:41:24] <jthornton> yes
[08:41:36] <Simonious> If I restart linuxCNC will those same values be in the G54 offset? Assuming my gcode doesn't set offsets (it doesn't, but it could, right?)
[08:41:43] <jthornton> questions are why we hang out here when we are not shooting the bull
[08:41:50] <Simonious> :)
[08:42:18] <jthornton> yes, unless you change them they will still be there. you can verify with a debug in the mdi window
[08:42:29] <jthornton> http://linuxcnc.org/docs/2.7/html/gcode/overview.html#gcode:debug
[08:42:37] <Simonious> or I can verify by just restarting linuxCNC :P
[08:42:55] <jthornton> yes
[08:43:06] <Simonious> excellent
[08:43:22] <jthornton> cool down done off to the shower... see you in the shop
[08:43:28] <Simonious> now.. I need to replace my home switches with something I can count on, because even with the motors locked I sometimes bump my position when changing out router bits.
[08:44:26] <Simonious> and rehoming the machine and going to the same offset will probably get me closer than hoping and guessing
[09:01:46] <MacGalempsy> sync: https://m.reddit.com/r/Reprap/comments/3vph62/any_way_to_retrieve_firmware_from_ramps_14/
[09:15:01] <Simonious> huh, in fusion360 when I create a derived operation I would have expected it to have the same selected points
[09:15:05] <Simonious> instead of.. none.
[09:24:27] <sync> MacGalempsy: as they say, it is perfectly possible
[09:40:03] <Simonious> oh strange.. I've got a 90degree operation that hits a series of holes
[09:40:29] <Simonious> Then I've got a drill operation that is supposed to hit the same holes
[09:40:41] <Simonious> and all of the drills are radiating OUT from the center point
[09:40:52] <Simonious> now I set this up as a repeating operation in a circle
[09:41:08] <Simonious> but.. I still would have expected each drill to be off the same direction each time
[09:42:15] <MacGalempsy> Simonious: sounds like a CAM issue
[09:43:07] <Simonious> I'm not convinced - I bumped the machine in X
[09:43:26] <Simonious> so if since I used a rotate operation when generating the Gcode..
[09:43:31] <MacGalempsy> are you using encoders?
[09:43:32] <Simonious> apparently that error rotated
[09:43:37] <Simonious> yes, why?
[09:44:16] <MacGalempsy> then if you bump the machine it should be accountable somehow
[09:44:42] <Simonious> that's a good point
[09:46:22] <MacGalempsy> maybe jog to the hole, write down the absolute position, home, then move the machine to the wanted coords and look at the difference
[09:50:43] <gregcnc> do the encoders talk to Linuxcnc or just back to the stepper drives?
[09:55:15] <Simonious> just the drives!
[10:00:48] <gregcnc> linuxcnc can't show you what the real position is, but the drives should try to correct for error. Is there a setting for deadband?
[10:00:57] <Simonious> I don't know
[10:01:31] <gregcnc> even if there isn't it can't be much
[10:02:34] <Simonious> so.. ignoring that, because I used a rotate operation, bumped the tool in X and then ran the operation, did it literally rotate the whole operation, so relative X was rotated?
[10:03:14] <archivist> how can we guess what you did
[10:04:48] <gregcnc> using coordinate rotation in linuxcnc or a pattern in CAM?
[10:05:17] <archivist> and define "bumped"
[10:05:48] <archivist> that is not a technical term from the linuxcnc manual iirc
[10:06:18] <gregcnc> yeah i don't like the idea that the drives aren't trying to maintain position. check your configuration. if you can't change tools etc. without losing position how will you make anythign accurately?
[10:09:25] <gregcnc> I've been using gecko servo drives for 10 years and never lost position
[10:11:09] <Simonious> pattern in CNC - fusion360
[10:11:39] <Simonious> gregcnc: yeah, that is most certainly a concern for me
[10:12:06] <gregcnc> once you lose position in the all bets are off, the part is scrap anyway
[10:12:11] <Simonious> I can replace the XY home with super accurate stops and then rehome between tool changes
[10:12:27] <Simonious> gregcnc: well, I'm working in wood so I can get away with a lot
[10:12:40] <Simonious> most of what I'm doing doesn't require more than visual precision
[10:12:49] <Simonious> which.. is more than I can line up by eye when the work is on the machine.
[10:13:02] <gregcnc> sure, but the encoders have a purpose, make then do their job
[10:13:23] <Simonious> I'm a novice, but I'm listening.
[10:13:41] <gregcnc> check the drive manuals and se what's wrong
[10:13:59] <Simonious> why do you think something is wrong? the drives aren't setup to talk to linuxCNC
[10:14:23] <gregcnc> neither are my gecko, but I can put torque on the servo and it reacts
[10:14:54] <Simonious> I'm running gecko 320s
[10:15:11] <Simonious> on steppers with encoders
[10:16:39] <gregcnc> how are you using 320 on steppers?
[10:17:01] <gregcnc> that's what I'm using
[10:17:23] * Simonious ponders
[10:17:59] <Simonious> they are functionally servos
[10:18:13] <gregcnc> 320 can't drive a stepper motor
[10:19:05] <gregcnc> part number of your motor?
[10:19:11] <Simonious> https://goo.gl/photos/2uAffpNSmiNutPMJ6
[10:19:43] <gregcnc> OK those are dc brush motors
[10:19:49] <Simonious> my mistake
[10:19:58] <gregcnc> did you do any tuning on the 320?
[10:20:11] <Simonious> in ancient times
[10:20:16] <Simonious> not done by me
[10:21:24] <gregcnc> OK, gecko will error out if they are pushed too far from their intended position. I think its 128 encoder counts for those old ones.
[10:21:42] <Simonious> been there done that
[10:21:46] <gregcnc> if error is not connected to linuxcnc it just loses position
[10:22:13] <gregcnc> if it is connected linuxcnc should also estop
[10:22:16] <Simonious> I ONLY have outputs to the geckos. I have just 2 inputs - HOME, STOPS
[10:22:27] <Simonious> that would be nice
[10:23:58] <gregcnc> I don't have error connected
[10:24:18] <gregcnc> my setup is terrible
[10:24:37] <Simonious> mine is improving, but not great
[10:24:53] <MacGalempsy> need a better pid tune?
[10:25:04] <gregcnc> what happens if you try to turn the ball screw/motor while machine is on?
[10:25:19] <gregcnc> could be tuning
[10:25:21] <Simonious> it's in braking
[10:25:30] <Simonious> so, very hard to moe
[10:25:31] <Simonious> *move
[10:25:49] <gregcnc> not braking, trying to maintain a position
[10:26:00] <Simonious> but.. when I'm bearing down on the router head to change tools, sometimes I nudge it a little :/
[10:26:26] <gregcnc> then the drive is erring out
[10:26:38] <gregcnc> need to imporve you tool change procedure
[10:26:57] <gregcnc> you could rehome
[10:27:09] <Simonious> yeah.. I haven't tested home accuracy
[10:27:16] <Simonious> but it's probably better than my eyeball
[10:27:51] <gregcnc> do your encoders have index signal?
[10:27:59] <Simonious> I don't know.
[10:28:13] <Simonious> what is that, how do I know?
[10:28:26] <gregcnc> specs, man, specs
[10:28:47] <Simonious> ahh, look up the servos
[10:28:50] <Simonious> ok
[10:28:57] <gregcnc> part number -> data sheet -> power to change the world
[10:29:18] <gregcnc> I'd look at the encoder first
[10:31:02] <gregcnc> if you don't have anymore inputs though it won't help
[10:31:15] <FloppyDisk5_25> I can see we need to create some 'powered by Lcnc' stickers to cover up that mach3 sticker...
[10:32:17] <Simonious> :D
[10:32:32] <Simonious> I've got inputs, I'm only using 2
[10:33:06] <Simonious> I'm saving them.. want to put in a touch plate at some point, maybe a spindle control
[10:33:16] <Simonious> otherwise XYZ home would each have thier own input
[10:33:30] <Simonious> though I *could* always use a second parallel port...
[10:33:47] <gregcnc> each index signal would need an input
[10:33:53] <Simonious> is
[10:33:55] <Simonious> ish
[10:34:13] <gregcnc> the you can home with index very accurately
[10:34:27] <gregcnc> those look like us digital encoders
[10:34:45] <Simonious> https://goo.gl/photos/JWcNd1Bx2B8mQuuk7
[10:34:57] <Simonious> good eye!
[10:35:09] <gregcnc> also on my machine
[11:28:39] <nikre> i have a cnc parallel port breakout board which has a pin that outputs 0-10v for spindle. my spindle driver changes spindle speed using a potentiometer. what do i need to have the board control the spindle speed?
[11:29:34] <JT-Shop> http://mesaus.com/index.php?route=product/product&path=65&product_id=91
[11:30:35] <nikre> nope i would like the prepare it myself
[11:31:35] <gregcnc> what kind of drive is it?
[11:32:29] <nikre> cheap chinese, wait i will find the link
[11:32:30] <JT-Shop> ##electronics
[11:34:44] <nikre> this one https://www.aliexpress.com/item/500W-spindle-power-input-220v-output-110v-6A-take-with-infinitely-adjustable-speed-controller-50-60/32271742252.html?spm=2114.13010608.0.0.bc3bxM
[11:38:44] <gregcnc> that's a new one, idk
[11:40:55] <archivist> nikre, measure from ground each end of the pot, (start on the AC (your local mains) range)
[11:41:38] <archivist> the pot might be connected between 0 and 10v
[11:43:50] <nikre> yeah i thought the same. i will do it. but the speed might be reverse the potentiometer voltage reading.
[11:43:58] <JT-Shop> amazing the hot glue machine is in the us
[11:44:24] <archivist> nikre, no worries linuxcnc can invert
[11:44:32] <nikre> oh thats great
[11:44:36] <nikre> ty archivist
[11:44:44] <Erant> I still have to convert my spindle to be controlled by the 5i25. Eh.
[11:44:57] <archivist> nikre, more likely that the pot is somewhat "live"
[11:45:24] <MacGalempsy> JT the day I ordered my ramps kit, i also ordered some bedding. the ramps made it from shenzen in less than 48hrs. the bedding took a week from nj
[11:45:27] <nikre> pwm driver?
[11:45:33] <nikre> no it's just a pot
[11:45:38] <Erant> If it's a cheap Chinese one, it's actually more likely that it's connected to a 555
[11:46:00] <Erant> Which means it's actually dependant on the resistance and not just acting as a voltage divider.
[11:46:22] <JT-Shop> bedding?
[11:46:25] <archivist> nikre, I know, sometimes the circuit is NOT mains isolated so the POT is dangerous
[11:47:10] <JT-Shop> even more so on your side of the pond with 220v
[11:47:34] <Erant> archivist: fwiw, from what the thing looks like, I'm going with it being connected to a 555 and that doing the PWM.
[11:48:57] <archivist> Erant, I have seen these things drive mosfets/thyristors direct on mains
[11:49:17] <archivist> without any sensible opto isolation
[11:49:31] <Erant> Oh, sure sure.
[11:50:20] <Erant> I've seen enough bigclivedotcom YouTube videos to know that there's really nothing they won't do.
[11:53:18] <Erant> Oh. In my efforts to polish a turd, I was going to replace the gibs and nuts on my machine. Any specific type of brass I should be using?
[11:53:53] <archivist> never seen brass gibs used in a quality machine
[11:54:06] <Erant> Well, they're steel right now.
[11:54:17] <archivist> bronze nuts
[11:54:18] <Erant> (What do they use?)
[11:54:36] <archivist> a steel usually
[11:55:12] <MacGalempsy> yeah comforter set
[11:55:13] <archivist> I would just bed it/scrape what is there, make them fit properly
[11:55:53] <JT-Shop> http://www.practicalmachinist.com/vb/general/gib-material-149402/
[11:56:38] <gregcnc> yeah, bronze, cast iron
[11:58:15] <sync> even just steel works
[11:58:29] <sync> cast on steel is an ok pair
[11:58:51] <Erant> I think it's cast on steel.
[11:59:16] <Erant> Same with the nuts (cast nut)
[12:02:05] <Erant> I was going to get the machine into as good of a shape as I can get it, use it for the next year or two to learn as much as I can while saving up for a proper setup.
[12:04:16] <archivist> on my old hobbymat, when I stripped the cross slide, it looked like they had cut the V with a blunt tool, base was not flat, inner V was round, gib itself hardly touched
[12:05:31] <Erant> Yeah, I have some more tools to collect before I can scrape.
[12:06:06] <archivist> I used a needle file for bulk removal
[12:06:39] <archivist> now I have better docs I would measure properly
[12:08:43] <archivist> ant a tin or tube of Stuart Engineers Micrometer Blue Marking
[12:08:56] <archivist> gets everywhere :)
[12:09:12] <JT-Shop> blue fingers :)
[12:10:16] <archivist> and given chance, it will capiliary out the tin, keep level
[12:14:43] <renesis> an ME manager once looked at me confused when i said where is needle file, he like "needle file?!"
[12:14:51] <renesis> i wanted to slap
[12:16:11] * archivist tests renesis with "pivot file"
[12:17:11] <renesis> whats a pivot file!?
[12:17:54] <archivist> expensive https://www.eternaltools.com/clock-pivot-files
[12:18:28] <renesis> oh neat trapezoid
[12:18:55] <archivist> very fine with other end to burnish, gets a mirror on a rotating shaft
[12:19:05] <renesis> thats cool i have to try and use skinny triangle needle file for stuff like that
[12:19:25] <Erant> archivist: I need a surface plate, and one of those flat... whatever they are.
[12:19:36] <archivist> use a bit of lathe tool steel as a burnisher
[12:20:31] <archivist> to prepare it slide side ways on a very fine wet and dry
[12:20:56] <MacGalempsy> supposedly shipping from hong kong and shenzen are subsidized
[12:22:50] <renesis> by who?
[12:22:59] <MacGalempsy> the chinese gov
[12:23:00] <renesis> by china?
[12:23:16] <renesis> how come our government isnt awesome like china
[12:23:20] <renesis> tf
[12:23:38] <MacGalempsy> one of their tools to get cheap stuff here cheaper
[12:24:19] <MacGalempsy> which gov is that renesis?
[12:24:24] <IchGucksLive> hi
[12:24:30] <MacGalempsy> :)
[12:24:46] <IchGucksLive> Indian summer start weekend in our forest here
[12:25:17] <IchGucksLive> With Steel rides the forest
[12:26:17] <IchGucksLive> http://tannenwald-blog.blogspot.de/2015/06/steel-rides-forest-2016_26.html
[13:00:22] <IchGucksLive> Loetmichel: bist du da
[13:07:11] <MacGalempsy> can spme one tell me when a warm up is needed on a mill?
[13:07:31] <MacGalempsy> do all mills need this?
[13:07:38] <IchGucksLive> when many oil is involved
[13:07:55] <cradek> that's not a thing I've seen anyone do
[13:07:57] <IchGucksLive> no exept you are in alaska or sibirian
[13:08:14] <SpeedEvil> Bringing it to a constant temperature - yes
[13:08:15] <cradek> for a very precise temperature-compensated machine, sure, but for normal work, nope
[13:08:25] <IchGucksLive> geard spindle heads like to warmup
[13:08:28] <cradek> some machines have coolant running through the ballscrews
[13:08:37] <MacGalempsy> ah. ok
[13:08:52] <SpeedEvil> that is - you probably don't want to come in with the shop at -10C and heat it up to 20C and immediately start cutting
[13:09:01] <cradek> some machines with one-shot lube let you do a manual pump - it doesn't hurt to do this once or twice when you start a machine that's been idle for a while
[13:09:03] <MacGalempsy> i have a geared spindle. any suggestions to speed and duration?
[13:09:26] <cradek> suggestion is don't worry about it
[13:09:53] <MacGalempsy> ok. im not in alaska nor siberia
[13:09:55] <SpeedEvil> If your machine is idle for a long time, perhaps 30s at low speed might not be a bad plan
[13:09:59] <renesis> some machines dont have cooled ways, and dont have preheaters, and then their builders go out of business when the california ground china castings warp and throw shit out like a mil
[13:10:38] <cradek> most important is use the correct oils. other stuff is superstition.
[13:10:49] <gregcnc> spindle will change Z relative to the table as it warms up depending on your tolerances you may want to pay attention
[13:10:55] <MacGalempsy> i just use what came in it
[13:11:07] <renesis> dont buy china castings
[13:11:34] <MacGalempsy> which is some kind of oil, but the screws use lithium grease
[13:12:33] <MacGalempsy> renesis: i try to stay away from chinese tools
[13:12:37] <renesis> my machine got way happier when i cleaned the lithium grease off and use vactra no2
[13:12:52] <gregcnc> lathes are more sensitive to diameters drifting with temperature
[13:12:54] <renesis> macgalempsy: i was talking about an american CNC machine company
[13:12:56] <cradek> I use vactra 2 on my big lathe
[13:12:58] <renesis> FADAL specifically
[13:13:07] <MacGalempsy> interesting. it holds .0001" pretty well
[13:13:10] <renesis> my guess is HAAS uses bunch of china parts, too
[13:13:48] <renesis> shit their formula 1 effort was pretty much buy everything from ferrari and bolt it onto a dalara chassis, they seem okay with outsourcing
[13:13:59] <MacGalempsy> lol
[13:14:45] <MacGalempsy> the one video ive seen of the haas factory said they make a high % of stuff in CA
[13:14:55] <MacGalempsy> even the controllers
[13:15:21] <renesis> its build here, and they have money for cali fabbed PCB but i wouldnt be surprised if they used a china boardhouse
[13:15:29] <gregcnc> http://www.jetworldwide.com/blog/low-cost-delivery-from-china-to-the-usa-explained
[13:15:37] <renesis> wouldnt matter, china can do PCB well
[13:16:02] <renesis> but i wouldnt be surprised if they had a lot of their little bits made in china
[13:18:32] <MacGalempsy> as longas they are not chinese resistors
[13:19:20] <pcw_home> we've had PCBs made in USA, Mexico, Korea and China. The Chinese PCBs have been consistently the best quality
[13:19:50] <roycroft> the chinese resistors were very effective against the japanes invasion in many parts of the country
[13:19:54] <roycroft> do not underestimate them
[13:20:35] <MacGalempsy> they didnt do so well in nanking
[13:21:13] <roycroft> nanking is not all of china
[13:35:54] <IchGucksLive> yes i agree on pcw the quality of the 3040 is amazing at that price range
[13:39:18] <IchGucksLive> here made in Germany ;-) http://www.ebay.de/sch/sis.html?_nkw=cnc+milling+engraver+router+MA+1+5KW+4+Axis+6040+Graveurausstattung+Graviergerat&_itemId=141937639835&_trksid=p2047675.m4096
[13:43:40] <IchGucksLive> GN8
[13:43:54] <Mac-Mill> alright. the edm manual came in!
[13:49:46] <JT-Shop> yea you will be blowing things up soon
[13:53:36] <Erant> Damn. I had no clue bronze was that expensive.
[13:54:25] <Erant> 1/4"x4"x12" strip of 936 bronze is $139
[13:54:54] <andypugh> That does seem quite expensive
[13:55:30] <Erant> That's McMaster. 932 seems cheaper, still expensive.
[13:56:28] <Erant> 954 is cheapest, probably because of its high Al content.
[13:56:45] <JT-Shop> 954 comes in smaller widths
[13:57:17] <Erant> Yeah. Compared to the same size 932 and 936 it's cheaper though.
[13:57:20] * JT-Shop wanders inside to get a monkey pickle
[13:57:32] <andypugh> Erant: http://www.ebay.com/itm/954-Bronze-Oversize-Flat-Bar-1-4-Thick-x-4-Wide-x-36-0-Length-/111760597246?hash=item1a057360fe:g:2~cAAOSwu4BV1flF would be cheaper if you needed 36"
[13:57:50] <Erant> Haha.
[13:58:52] <Erant> I was looking for nut material, but I got distracted by the large numbers for bar stock.
[14:00:38] <JT-Shop> if you have 8 numbers how do you get every combination of any 3 numbers from the set?
[14:02:33] <andypugh> Does the sequence matter?
[14:03:13] <JT-Shop> hmm, no
[14:03:22] <andypugh> 1,1,1 1,1,2 1,1,3 … 1,2,1 1,2,2, 1,2,3….. ….. 2,1,1
[14:03:35] <JT-Shop> unique numbers
[14:03:38] <andypugh> 3 nested loops
[14:03:54] <Erant> JT-Shop: The amount of combinations, or the actual combinations?
[14:04:01] <JT-Shop> 1,2,3 1,2,4...
[14:04:09] <JT-Shop> the actual combinations
[14:04:20] <Erant> Python?
[14:04:23] <JT-Shop> I guess a loop
[14:04:25] <JT-Shop> sure
[14:04:28] <andypugh> OK, then for x(1 to 6) for y (x to 7) for z (y to 8)
[14:07:38] <Erant> Oh, missed the bit where the sequence doesn't matter.
[14:10:45] <Erant> for i in range(1, 7):
[14:10:46] <Erant> for j in range(i + 1, 8):
[14:10:46] <Erant> for m in range(j + 1, 9):
[14:10:47] <Erant> print i,j,m
[14:10:51] <Erant> something like that.
[14:11:02] <JT-Shop> let me try that
[14:14:32] <JT-Shop> yep that works just the output confused me for a second or three lol
[14:14:41] <Erant> Blame andy
[14:14:52] <JT-Shop> lol
[14:15:41] <JT-Shop> the accent you think?
[14:17:10] <Erant> For sure.
[14:17:31] <JT-Shop> thanks
[14:17:45] * JT-Shop goes back to doing something I think
[14:29:46] <DGMurdockIII> hey are the cnc/router bits that you can get here worth it https://shop.carbide3d.com/
[14:31:01] <Erant> Worth what
[14:34:50] <renesis> i wouldnt give them money
[14:34:56] <renesis> their machines are kind of silly
[14:35:05] <renesis> and expensive as fuck
[14:37:06] <JT-Shop> get router bits from https://www.onsrud.com/
[14:40:49] <DGMurdockIII> ok
[14:43:01] <DGMurdockIII> open source cnc controller software?
[14:43:34] <DGMurdockIII> that is not linux cnc
[14:47:31] * Erant looks at the channel name
[14:48:03] <Erant> DGMurdockIII: There's grbl. What's wrong with LinuxCNC?
[14:48:46] <DGMurdockIII> nothing it just i use windows
[14:49:17] <Erant> You use Windows for what?
[15:00:10] <CaptHindsight> renesis: but they only use the finest hardwoods to make the plywood router enclosure
[15:01:02] <CaptHindsight> https://cdn.shopify.com/s/files/1/0683/0809/products/IMG_9644_1024x1024.jpg?v=1452715007
[15:01:55] <DGMurdockIII> i dont have that cnc i was just wondering about there bits
[15:02:06] <DGMurdockIII> i mean router bits
[15:04:52] <Erant> DGMurdockIII: Sure. What do you use Windows for? Are you aiming to run this on your desktop computer or something?
[15:05:05] <Erant> DGMurdockIII: And what CNC machine do you have?
[15:05:19] <DGMurdockIII> yes on a desktop mechine i built
[15:07:23] <Erant> The only things that I'm aware of that runs on "Windows" are Mach3 and Mach4. Mach3 is old, Mach4 is expensive.
[15:08:14] <Erant> I'm assuming you'll be doing this through a parallel port?
[15:22:06] * MacGalempsy hopes for no explosions on a macroscopic scale.
[15:24:29] <MacGalempsy> the startup cycle went as supposed, now reading about cut times and electrode sizing
[15:24:37] <kyle___> any solidworks pros around?
[15:24:57] <Tom_itx> a few users
[15:25:04] <DGMurdockIII> yeah i have Mach3
[15:25:09] <Tom_itx> i'm sorry
[15:25:11] <MacGalempsy> :[
[15:25:24] <MacGalempsy> lol. too fast for me
[15:25:34] <MacGalempsy> the razor?
[15:25:56] <Tom_itx> man what are friends for...
[15:26:15] <Tom_itx> dude just brought ~100 lbs of books by and dumped em in my lap
[15:26:30] <zeeshan> excellent material for camp fire
[15:26:30] <Tom_itx> i just got rid of a bunch myself...
[15:27:51] <Tom_itx> zeeshan what you been up to?
[15:28:21] <Tom_itx> you need an old sumographic digitizer pad?
[15:28:22] <zeeshan> work, camp, work, camp, work, race, work, camp
[15:28:23] <zeeshan> :P
[15:28:24] <Tom_itx> that was on the pile...
[15:28:47] <zeeshan> wow
[15:28:53] <zeeshan> i didnt even know those existed
[15:29:06] <zeeshan> a lot of stress strain data in the atlas of stress-strain
[15:29:08] <zeeshan> curves
[15:29:12] <zeeshan> its not in tabular form
[15:29:33] <zeeshan> ill be back later
[15:29:34] <zeeshan> need food
[15:46:51] <Erant> DGMurdockIII: So... What are you asking?
[15:48:21] <JT-Shop> anyone need a color inkjet plotter?
[15:48:38] <JT-Shop> zeeshan: I'm finally getting my hot glue machine lol
[15:49:20] <MacGalempsy> no room here, but how wide?
[15:49:54] <JT-Shop> 24" roll feed HP 500
[15:51:27] <JT-Shop> http://semo.craigslist.org/sys/5794234767.html
[15:52:27] <MacGalempsy> looks like fun.
[15:59:44] <CaptHindsight> http://www.laserresearch.net/optics.asp US source for laser optics that are in stock or have short turn times
[16:03:19] <CaptHindsight> JT-Shop: turn it into a powder + binder 3d printer
[16:04:06] <CaptHindsight> make water soluble patterns for casting
[16:05:52] <CaptHindsight> https://www.youtube.com/watch?v=mu3pgrBpT20 Binder Jet Printer
[16:11:41] <JT-Shop> to noisy lol
[16:12:00] <andypugh> I wonder what binder they use?
[16:12:29] <CaptHindsight> depends on the printhead
[16:13:26] * JT-Shop programs a little C
[16:13:38] <Lowridah> uhh that's a big C
[16:13:43] <Lowridah> a little c is like c
[16:13:49] <Lowridah> adoy
[16:14:10] <andypugh> Fancy ç
[16:14:24] <JT-Shop> lol
[16:14:31] <Erant> https://www.youtube.com/watch?v=Hn8hDY4bvpI (This Old Tony)
[16:14:59] <CaptHindsight> andypugh: for powdered sugar you can use water
[16:15:22] <andypugh> I want to make sand moulds
[16:15:39] <CaptHindsight> if you don't want it to be water soluble you can add an acrylate
[16:17:39] <CaptHindsight> andypugh: for sand you want to coat the sand first with a heat set adhesive and then only inkjet the shell, then back the mold to make it solid
[16:17:51] <CaptHindsight> back/bake
[16:17:56] <andypugh> Yeah, I have heard that
[16:19:40] <andypugh> The problem is finding a printhead that I want to afford, then finding a compatible binder.
[16:21:09] <CaptHindsight> Epson piezo that you can cannibalize from a desktop printer
[16:22:02] <CaptHindsight> Xaar heads start at ~$300 for ~120 nozzles
[16:22:25] <Deejay> gn8
[16:23:35] <CaptHindsight> everything else is $1k and up
[16:34:27] <CaptHindsight> andypugh: if you use an older TIJ (thermal) cartridge it will last for maybe a liter or two before it starts dropping nozzles
[16:35:24] <Erant> I've seen some DIY ones with piezo elements.
[16:35:48] <Erant> The biggest thing being the hole size and shape, I think.
[16:36:00] <Erant> Well... most important. It is obviously actually the smallest thing.
[16:51:56] <CaptHindsight> you're better of with a miniature solenoid valve than the DIY ones I saw
[16:53:02] <CaptHindsight> http://reprap.org/wiki/Scratchbuilt_Piezo_Printhead
[16:53:45] <zeeshan> nice jthornton
[16:53:46] <zeeshan> what for tho
[16:59:40] <JT-Shop> print some small parts to hold oled and to learn about them
[17:00:03] <JT-Shop> I see that slic3r outputs LinuxCNC code so I want to try that as well

[17:28:14] <gregcnc> wait it's friday already?
[17:28:20] <MacGalempsy> no herr
[17:28:31] <MacGalempsy> herr
[17:28:31] <MacGalempsy> here
[17:28:31] <MacGalempsy> lol
[17:29:46] <JT-Shop> is for me lol
[17:30:02] <JT-Shop> going to Georgia tomorrow for my little sisters wedding
[17:30:22] <JT-Shop> and I solved the puzzle in C too http://paste.ubuntu.com/23253034/
[17:33:15] <Cdrew> anyone have latency problems on Wheezy but OK on 10.04?
[17:34:25] <Cdrew> I have tried 2 computers on wheezy now that I was sure would work fine and the latency is a problem.
[17:35:25] <JT-Shop> I've had latency problems with old vs new pc vs os
[17:35:40] <JT-Shop> 10.04 can still work...
[17:36:20] <JT-Shop> I have 3 machines still running 10.04...
[17:41:03] <witnit> emc for lyfe
[17:52:51] <andypugh> It’s Friday for me. I am burning off some flexitime
[17:53:26] <JT-Shop> nice
[17:56:33] <JT-Shop> http://paste.ubuntu.com/23253214/
[17:56:45] <JT-Shop> seems to work
[17:57:11] <andypugh> CaptHindsight: Apparently this guy gets a lot of folk asking hom to make them solenoid valves for printer projects: http://www.f1-2000.co.uk/index.php?f=fuel_injectors
[18:03:59] <Tom_itx> JT-Shop you're not riding there are you?
[18:05:34] <JT-Shop> taking the Honda... car
[18:05:45] <JT-Shop> civic hybrid 45mpg
[18:06:15] <JT-Shop> weather is supposed to be nice
[18:06:38] <Tom_itx> i'd hate to think of driving thru atlanta in the rain
[18:07:15] <JT-Shop> skipping atlanta and taking 53
[18:07:24] <Tom_itx> probably a good call
[18:07:37] <Tom_itx> we go to savannah once in a while
[18:07:37] <JT-Shop> checked with my sister
[18:07:41] <jdh> that looks almost identical to my code, including the commented out printfs
[18:08:03] <JT-Shop> jefferson ga is the destination
[18:08:13] <JT-Shop> they live in winder ga
[18:08:33] <JT-Shop> jdh: cool
[18:08:49] <JT-Shop> the c code or the python
[18:08:56] <jdh> c,
[18:09:01] <JT-Shop> oh nevermind you said printf
[18:09:07] <jdh> I have no python style
[18:09:30] <JT-Shop> that's my first really functional C code lol
[18:10:12] <JT-Shop> even with two dimensional arrays
[18:13:36] <Jymmmm> CaptHindsight: You think there is any REAL benefit of running parallel 12ga lines by chance?
[18:13:59] <JT-Shop> what are you trying to do Jymmmm ?
[18:14:53] <JT-Shop> Tom_itx: I hate to think of driving in, around, or through Atlanta lol
[18:15:40] <Jymmm> JT-Shop: Running a new 220C@20A circuit that I'll split into two 110V@20A circuits. I have LOTS of 12ga wire, but as planning on pulling 2x 12ga (8 conductors total) as it's a 75ft run and I plan on backfeeding on the same circuit too (in the future) all thu 3/4" conduit
[18:16:25] <JT-Shop> 220v@20a is equal to 120v@40a
[18:16:40] <Jymmm> JT-Shop: But TWO 110V cicuits
[18:17:00] <Jymmm> ...each at 20A
[18:17:07] <JT-Shop> yep
[18:17:35] <JT-Shop> you need 2 hots, a neutral and maybe a ground
[18:17:45] <Jymmm> Whle not "legal" (by code), I was thinking of runnng parallel conductors
[18:17:50] <JT-Shop> 75' is nothing
[18:17:50] <MacGalempsy> why 8 conductors?
[18:18:04] <Jymmm> 12ga + 12ga = 10ga
[18:18:11] <Jymmm> MacGalempsy: voltage drop
[18:18:40] <JT-Shop> 12 awg can carry 20amps for 75' and you probably won't load it to max anyway
[18:18:49] <JT-Shop> ain't much voltage drop in 75'
[18:19:11] <JT-Shop> you got thhn? or similar?
[18:19:12] <Jymmm> 4.45votls
[18:19:21] <Jymmm> THHN (stranded)
[18:19:51] <JT-Shop> by all means make the conduit PVC Pipe Very Crowded
[18:19:52] <Jymmm> 2.22volts drop using 2 parallel condutors
[18:20:10] <Jymmm> JT-Shop: I'm allowed up to 8 12ga in 3/4
[18:20:31] <JT-Shop> bet you can get 10 if no bends
[18:20:52] <Jymmm> shtit load of bends in the last 20 ft =)
[18:21:12] <Jymmm> first 55ft is a pure straight run =)
[18:21:21] <JT-Shop> nothing more fun than pulling a bunch of wire through old PVC pipe lol
[18:21:29] <Jymmm> brand new
[18:21:44] <JT-Shop> can't have more than 360 degrees of bends without a pull box
[18:22:25] <Jymmm> one pull box at the end of the long run, three three bands, and another pullbox at the wall of the garage
[18:22:30] <JT-Shop> I was talking about a fun job
[18:22:51] <JT-Shop> three three bands?
[18:23:03] <Jymmm> then, three bends (90's)
[18:23:09] <JT-Shop> ah
[18:23:19] <Jymmm> typo, do you speak it?! lol
[18:23:36] <JT-Shop> sometimes it makes sense sometimes it does not
[18:23:47] <Jymmm> lol, not today it doesn't =)
[18:24:03] <JT-Shop> powering up the garage?
[18:24:29] <Jymmm> Well, the only dofference between 20A and 30A is a different breaker. Thus considering the 2 parallel conductors
[18:24:37] <JT-Shop> got a pull line?
[18:25:01] <Jymmm> It has one 15A 110v cicruit, adding this one for the laser and blower, plus 220V if needed in the future
[18:25:20] <Jymmm> pull line? as in fish tape? or rope?
[18:25:33] <JT-Shop> over 50' a rope
[18:25:58] <Jymmm> I have mason line in the 55ft run now, will replace with rope in a few minutes
[18:26:05] <JT-Shop> you can wad up some tissue and tie a string to it then suck it through with a vacuum
[18:26:36] <JT-Shop> then tie something stronger to that and pull back. pull the wire from the easy end to the hard end
[18:26:47] <Jymmm> ah shit, I tried blowing and that just made the line ball up, will try the vac on the last 20ft though =)
[18:27:13] <JT-Shop> you can blow but you need to meter the line in
[18:27:38] <Jymmm> plastic shopping bag cut down works great of a "wad"
[18:27:51] <JT-Shop> yea anything
[18:27:53] <Jymmm> as a ...
[18:27:59] <MacGalempsy> interesting how this EDM manual doesnt cover the 1/64 power setting, which woul theoreticall leave a rm10 finish
[18:28:33] <MacGalempsy> just have to extrapolate
[18:29:10] <MacGalempsy> now just need to cut some copper electrodes
[18:29:22] <JT-Shop> not using carbon?
[18:30:01] <MacGalempsy> for roughing, but finishing is best w copper
[18:30:10] <Jymmm> JT-Shop: Heh, this says 18 conductors... lol https://www.theautomationstore.com/maximum-number-of-conductors-in-conduit/
[18:30:12] <JT-Shop> didn't know that
[18:30:33] <JT-Shop> you can stuff a bunch of wire in 3/4"
[18:31:18] <MacGalempsy> the comparetor shows a 16 finish and its damn impressive
[18:31:26] <JT-Shop> Tom_itx: been on robotics?
[18:31:31] <CaptHindsight> Jymmm: I'd just run #12 and not double up
[18:31:33] <Tom_itx> a bit
[18:31:41] <Jymmm> Hmmm, 7volt drop at 30A (single conductor)
[18:31:47] <JT-Shop> wtf is thebear
[18:32:02] <Tom_itx> aussie
[18:32:07] <JT-Shop> ah
[18:32:10] <Jymmm> 3.5 volt drop parallel conductors.
[18:32:17] <Tom_itx> he's really pretty cool but been suffering ailments lately
[18:32:41] <CaptHindsight> you have to derate the conductors when you have more than 3 current carrying conductors in one conduit
[18:32:46] <Tom_itx> so now he rambles alot
[18:32:54] <JT-Shop> that's no lie
[18:33:15] <Jymmm> CaptHindsight: derate? for what?
[18:33:52] <Tom_itx> bouncer, dj that sort...
[18:33:58] <CaptHindsight> you can't have 20A breakers on #12 thhn if there are more than 3 of them carrying current in the same conduit
[18:34:34] <Jymmm> CaptHindsight: and why the hell not (in a nut shell) ?
[18:34:44] <malcom2073> Jymmm: Heat
[18:34:55] <Tom_itx> i did an avr mixer board for him once
[18:35:12] <CaptHindsight> conduit fill is one thing, physical fill, then there is derating the current carrying ability of the conductors when you go above 3
[18:35:18] <malcom2073> I like Tom's AVR projects
[18:35:47] <Jymmm> CaptHindsight: but they are parallel, not additiona circuits
[18:35:53] <Tom_itx> the programmer was the most fun
[18:36:28] <CaptHindsight> Jymmm: I told you what I would do, the rest is up to you
[18:36:37] <jdh> I will be using an arduino for my next toy instead of a raw avr. I feel somewhat unclean, but not enough to worry about.
[18:36:56] <Tom_itx> you must cleanse yourself when done
[18:37:01] <malcom2073> With fire
[18:37:12] <Jymmm> CaptHindsight: Fine, be that way! <sticks nose in air> Morphy's law says that'lll need 30A as soone as I finsih this projects! lol
[18:37:19] <Jymmm> Fine, not fire.
[18:37:21] <jdh> the bootloader just makes it too easy.
[18:37:31] <Jymmm> CaptHindsight: (ty)
[18:37:40] <malcom2073> jdh: I've taken to writing raw AVR code and using the bootloader to load it
[18:37:45] <Tom_itx> that part is ok it's all the bloated code i don't like
[18:37:57] <CaptHindsight> Jymmm: there is physics and electrical code, I'm sorry I don't include your emotional needs in the wire choices :)
[18:37:58] <Tom_itx> they basically got it from app note 109
[18:38:30] <Jymmm> CaptHindsight: Hey, I got the wire for free damnit. and 10ga is damn expensive =)
[18:40:14] <JT-Shop> Jymmm: damn the torpedoes full speed ahead
[18:40:21] <CaptHindsight> Jymmm: run 4 15a ciscuits :)
[18:40:43] <Jymmm> JT-Shop: lol
[18:40:47] <Jymmm> CaptHindsight: HA!
[18:41:18] <Jymmm> MORE POWER!!! UG UG UG
[18:41:44] <Jymmm> alright, I gots some wire pullin to do before the rain starts!
[18:41:49] <Jymmm> thanks all =)
[18:42:05] <Tom_itx> y, you're very welcome
[18:43:17] <Tom_itx> soap the wire good if you're going very far
[18:46:03] <Tom_itx> jdh, if you have any code size at all serial bootloader programming is slow
[18:50:51] <Erant> jdh: I can also recommend a Teensy, better bootloader.
[18:51:54] <Erant> In general though, there's very few good reasons to use an AVR these days.
[18:54:29] <Tom_itx> they are simple
[18:54:38] <Tom_itx> arm is alot more complex
[18:56:28] <Tom_itx> tsr's appear not to work in a dos window
[19:03:40] <Erant> Tom_itx: Why is ARM a lot more complex?
[19:04:40] <Tom_itx> more registers to deal with
[19:05:11] <Erant> Most of the complexity is abstracted away by an 'init()' call supplied by the vendor.
[19:05:13] <Tom_itx> iirc most are programmed via jtag
[19:06:25] <Erant> Nah. Most of 'm have USB bootloaders these days. Some actually just expose a memory stick interface, and you can drag and drop your firmware on there.
[19:08:20] <jdh> this will just read a few i2c ADC's and spit out raw counts over bluetooth
[19:10:39] <thomaxo> Whats the best arduino cnc controller nowadays?
[19:10:52] <thomaxo> arduino-alike
[19:10:53] <malcom2073> Depends on how you define best
[19:11:05] <thomaxo> quick and precise
[19:11:06] <malcom2073> The least shittiest imo is tinyg2
[19:11:19] <malcom2073> But you can't beat linuxcnc on a rpi
[19:11:41] <thomaxo> What are the advantages of linuxcnc vs for example tinyG?
[19:12:25] <malcom2073> linuxcnc is significantly less buggy in my experience than tinyg2. And WAY more active developers working on it
[19:12:33] <malcom2073> And can do way more stuff
[19:13:17] <thomaxo> so linuxCNC is more comparable to say, heidenhain controller?
[19:13:36] <malcom2073> No clue what that is
[19:13:59] <thomaxo> cnc controller, amongst the likes of fanuc
[19:14:14] <malcom2073> I've never used a real cnc controller so I couldn't speak to that, others here have though
[19:16:31] <TurBoss> heidenhain has a lot of features
[19:17:08] <TurBoss> like make pockets from a path
[19:17:35] <malcom2073> That sounds more like conversational gcode sort of stuff
[19:17:48] <TurBoss> eg you have a square in gcode then the heidenhain control can make a hole in base of that square
[19:19:12] <TurBoss> more like linuxcncfeatures
[19:19:18] <TurBoss> but more
[19:19:19] <TurBoss> xD
[19:20:59] <gregcnc> wtf are automotive air hose fittings?
[19:21:27] <zeeshan> ??
[19:21:37] <tiwake> gregcnc: the push-pull plastic line fitting things?
[19:21:53] <Tom_itx> http://www.samsclub.com/sams/quick-coupler-set-ik1015s-5/prod17030205.ip?pid=_CSE_Google_PLA_Air_Compressors_&_Accessories&source=ifpla&CAWELAID=730010300000478868&adid=22222222627000016329&veh=sem
[19:21:53] <tiwake> except special, cause they need to not leak
[19:22:36] <gregcnc> those are the normal type, automotive look slightly different and don't fit
[19:22:49] <tiwake> gregcnc: like this http://www.china-pace.com/image/featured1.jpg
[19:23:57] <MacGalempsy> beachbumpete: how goes it?
[19:24:15] <gregcnc> http://www.portlandcompressor.com/compressor/couplers-and-fittings.aspx
[19:24:19] <gregcnc> i was not aware
[19:25:45] <tiwake> blame the department of transportation for having to make everything differently, though its the same thing
[19:26:33] <gregcnc> I just grabbed one off the shelf in the airtool section
[19:26:56] <gregcnc> the wrong one
[19:26:59] <Tom_itx> the 'industrial' type are more common
[19:27:21] <MacGalempsy> the automotive ones dont leak?
[19:28:59] <tiwake> MacGalempsy: don't make me laugh
[20:23:53] <MacGalempsy> that seemed implied by a previous comment
[20:48:09] <MacGalempsy> zeeshan: winning any races?
