[00:17:24] <andypugh> Valen: The disk failure was a red-herring, it was a problem with my driver code. I don't know what it was doing, but it was repeatable, and I found an infinite loop.
[00:17:42] <Valen> your writing sata drivers?
[00:18:08] <andypugh> No
[00:18:20] <andypugh> No idea why it messed the disk up.
[00:18:37] <andypugh> It is a Mesa card driver...
[00:19:18] <Valen> oh... well thats a bit of an issue
[00:19:35] <andypugh> It is fixed now.
[00:19:36] <Valen> unless you memory leaked into the sata?
[00:19:43] <andypugh> Something like that.
[00:27:18] <Valen> nasty
[00:27:25] <Valen> oh well good to hear its fixed

[00:46:51] <danimal_garage> ugh i debured and polished like 150 parts today, on top of running the mill all day
[00:53:05] -!- adb has quit [Read error: No route to host]
[00:53:20] <andypugh> On the bright side, that's 150 parts-worth of cash.
[00:54:20] <danimal_garage> true
[00:54:36] <danimal_garage> i just wanted to get everything done that i needed to send to anodizing
[00:54:46] <danimal_garage> that way i don't have to anodize them lol
[00:56:28] <Valen> lol
[00:56:30] <andypugh> Anodising does make things look nice, especially Clear
[00:56:40] <Valen> get em gold plated ;-P
[00:57:08] <Valen> I'd consider getting your gears nickel/chrome plated and advertise them as low friction
[01:02:51] <danimal_garage> eh
[01:03:13] <danimal_garage> let them wear out, then they'll have to buy more lol
[01:03:30] <danimal_garage> i make consumables for a reason
[01:06:14] <andypugh> Hard Anodising can make Aluminium very hard-wearing. It looks rather "technical" too.
[01:07:17] <danimal_garage> i tell them to buy my titanium rungs if they want long lasting
[01:07:24] <danimal_garage> rings*
[01:08:07] <andypugh> Boron, for extra antiweight!
[01:10:11] <ds3> speaking of titanium...is there a quick way to identify it?
[01:22:01] -!- FinboySlick [FinboySlick!~shark@] has joined #emc
[01:22:06] <andypugh> non-magnetic, very bright white sparks.
[01:22:16] <andypugh> But mainly, it looks like titanium.
[01:23:09] <andypugh> Also, it is a lot lighter than it looks like it should be.

[02:04:52] <Guest796> Hi, I am trying to calibrate an axis I have set up using stepconfig. I have jog set to go 0.1 Measured distance is 0.101 Should I go back into stepconfig and change the gear rationa bit?
[02:05:56] <l0st1nsp4c3> Guest796 servo or stepper? ballscrew? acme lead? and did you only go one direction? (cause if you went more then one backlash could be an issue)
[02:06:06] <l0st1nsp4c3> or belt driven i forgot to ask lol
[02:14:14] <l0st1nsp4c3> or don't say anything that always works =)
[02:14:55] <l0st1nsp4c3> Guest796 First thing i'd do is check if your measurement and movement are repeatable if you do this ten times in a row and obtain same result then I'd move on to the next step
[02:20:11] <Guest796> Sorry, I was eating! first axis is a stepper with a single ballscrew. I am only going one direction. Measurment seems to be cosistent - .1 and a few tenths every time
[02:21:17] <Guest796> Also this is my first time on the chat! I guess you can learn lots by just hanging around??
[02:23:38] <l0st1nsp4c3> of course
[02:23:57] <l0st1nsp4c3> so if i understood correctly
[02:24:05] <l0st1nsp4c3> you don't direct drive the ball screw you have some gears in there
[02:25:01] <Guest796> no, sorry, the x and y axis are a direct drive.z is belted, but I haven't started on that yet.
[02:25:26] <l0st1nsp4c3> ok but which axis is giving you the issue?
[02:26:09] <l0st1nsp4c3> a direct drive one?
[02:26:43] <Guest796> yes
[02:27:16] <l0st1nsp4c3> then why did you suggest going and changing gear ratio?
[02:27:35] <l0st1nsp4c3> if it's direct drive then there is no gear ratio to that should be messed with AFAIK
[02:27:56] <l0st1nsp4c3> you have the correct steps per rotation for your motors? and the correct TPI for your ballscrew?
[02:27:58] <Guest796> I am just trying to fine adjust the travel. I want it to fo one inch when I tell it to go one inch. what should I change in stepconfig?
[02:28:17] -!- mikeggg has quit [Read error: Connection reset by peer]
[02:28:37] <l0st1nsp4c3> Guest796 i don't recommend just changing stuff willy nilly without first making sure everything is configured correctly
[02:28:49] <Guest796> I think steps/rotation and tpi are correct, right now it's very close
[02:29:10] <l0st1nsp4c3> your steppers they are what 1.8degrees? so 200 steps for a complete rotation?....how many TPI
[02:29:29] -!- kljsdfhklj [kljsdfhklj!~ln@189-31-83-10.fnsce704.dsl.brasiltelecom.net.br] has joined #emc
[02:30:25] <Guest796> It is a x3 mill with a fusion conversion kit. I think the steppers are 1.8, 200 steps per rotation. tpi is 5.08
[02:30:41] <Guest796> I think!
[02:31:20] <l0st1nsp4c3> well
[02:31:29] <l0st1nsp4c3> do you know the model of your motor
[02:31:43] <l0st1nsp4c3> oh and your controller are you microstepping etc etc etc
[02:31:55] <Guest796> keling something, but that is all i know
[02:32:17] <Tom_itx> chinese driver
[02:33:14] <Tom_itx> http://www.kelinginc.net/KLDriver.html
[02:33:15] <l0st1nsp4c3> Guest796 you need to know more
[02:33:18] <Tom_itx> which one?
[02:33:53] <l0st1nsp4c3> you need to now your motors degree unipolar bipolar amps etc etc etc =P otherwise you cannot configure it correctly
[02:34:06] <l0st1nsp4c3> altho i would guess it's a 1.8deg 200steps per revolution
[02:34:16] <Guest796> driver should be set up ok, it is a 203v. I was reading about base periods etc, but I thought I would worry about tweaking it after I had the mill set up. Sorry my typing is slow.
[02:34:24] <Tom_itx> gecko
[02:34:28] <Guest796> yes
[02:34:38] <l0st1nsp4c3> gecko
[02:34:39] <Tom_itx> ok what about the steppers?
[02:34:39] <l0st1nsp4c3> nice
[02:34:47] <Tom_itx> that's the one i want to get
[02:34:53] <l0st1nsp4c3> im gonna guess some kelinginc as well
[02:35:04] <l0st1nsp4c3> i got a g540 low end gecko but works well so far
[02:37:48] <l0st1nsp4c3> right now i'm looking for some good end mill kits
[02:37:52] <Guest796> ok, I will confess! I had it set up with mach3, and it worked pretty well. so I think the driver and stepper are matched up etc. But Mach 3 had a little axis calibration thing where I told the axis to go one inch, then I measured how far it went and entered the actual value - wah lah, it adjusted it for me.
[02:38:48] <SWPadnos> try the Mach3 scale number in EMC
[02:39:21] <SWPadnos> you can do the same thing with EMC, but you have to divide for yourself (or use the calculator program that's already installed)
[02:39:47] <danimal_garage> he might be a spy
[02:40:25] <Valen> Ti is also warm to the touch like stainless ds3
[02:40:26] <SWPadnos> set the scale to what you think it might be, tell EMC to move 1 inch, measure the actual motion, and then set the scale to (whatever scale you started with) * (1/the amount of movement you measured)
[02:40:43] <SWPadnos> have fun with it. good night
[02:40:47] <Valen> your probably better off working it out mathimatically
[02:40:54] -!- emc2-buildmaster has quit [Ping timeout: 252 seconds]
[02:41:25] <l0st1nsp4c3> where do you guys buy your endmills?
[02:41:39] <Valen> that way your scale (should) be right on average over the length of the screw, not just over that bit
[02:41:47] <Guest796> ok swpadnos, are you saying I should just go into the ini file and change the scale there?
[02:41:53] <Valen> then use the screw adjust doohickey
[02:42:11] <SWPadnos> yes, or change the numbers in stepconf if you used that to generate the config
[02:42:12] <Valen> its linux, everything is in ini files ;-P
[02:42:58] <ds3> Valen: hmmm... trying to figure out if a peice of scrap is Ti; it is light like aluminum but shiney like stainless
[02:43:14] <Valen> touch it on a grinding something
[02:43:18] <l0st1nsp4c3> pfff
[02:43:20] <Valen> white sparks its Ti
[02:43:22] <l0st1nsp4c3> linux doesn't use .ini files
[02:43:29] <l0st1nsp4c3> everything in linux is in /etc =P
[02:43:31] <ds3> and gummed wheel makes it Al?
[02:43:33] <Guest796> I was trying to adjust the scale in stepconfig by adjusting the pulley teeth ratio. never thought to fo into the ini
[02:44:06] <Valen> basically ;->
[02:44:31] <l0st1nsp4c3> Valen heheh
[02:44:43] <Guest796> you lost me there , I am a linux nube, I really like it,but i should have started younger
[02:45:25] <Valen> you need to work out what part is wrong then fix that
[02:45:35] <Valen> if your using stepconf you should keep using it
[02:45:53] <Guest796> Hey, does anyone have emc2 tutorial videos?
[02:46:33] <Valen> if you change the ini file then use stepconf again it'll overwrite your changes
[02:46:42] <Guest796> Valen, then how do i adjust the scale number with stepconfig?? My original q
[02:46:53] <Valen> why do you want to adjust scale?
[02:47:35] <Guest796> because when I tell the axis to go 1 inch, it goes 1.001 (or something)
[02:47:57] <Valen> does it do that along the whole screw or in one spot?
[02:48:04] <Valen> what type of screw do you have?
[02:48:08] <Tom_itx> the screw sounds like it may be metric
[02:48:14] <Guest796> I don't know
[02:48:26] <Tom_itx> 5.08 sounds fishy
[02:48:30] <Valen> is it a bit of allthread, acme thread ballscrew?
[02:48:45] <Tom_itx> steppers are 1.8, 200 steps per rotation. tpi is 5.08
[02:49:07] <Valen> is .08 some imperial measurement?
[02:49:15] <Guest796> It is a screw that came with cncfusion conversion kit, maybe 5mm?
[02:49:34] <Valen> its the tpi you will be wanting to change
[02:50:23] <l0st1nsp4c3> already been threw that
[02:50:58] <l0st1nsp4c3> but he seems to want to just adjust
[02:51:01] <Valen> probably needs some more decimal places
[02:51:19] <Guest796> Seems like fine calibration of an axis would be a common problem...
[02:51:33] <Valen> not really
[02:51:33] <l0st1nsp4c3> my bet is on
[02:51:39] <l0st1nsp4c3> wrong TPI on leadscrew
[02:51:46] <Valen> you generally know what its all sposed to be
[02:52:01] <Valen> and adjusting the tpi means adjusting the tpi
[02:52:11] <Guest796> Maybee my indicator runs big!
[02:52:19] <Valen> steppers that do 200 steps per revolution dont do 200.01
[02:52:28] <l0st1nsp4c3> nope
[02:52:34] <l0st1nsp4c3> thus why i said to him before
[02:52:35] <l0st1nsp4c3> [22:28] <l0st1nsp4c3> Guest796 i don't recommend just changing stuff willy nilly without first making sure everything is configured correctly
[02:53:23] <Valen> I'm guessing each turn is going to move 0.196850394 inches
[02:53:35] <Valen> 5.079999992 TPI
[02:53:40] <Valen> it is a 5mm metric thread
[02:54:20] <Guest796> oh, is 5mm 5.079999992?
[02:54:29] <Valen> then you go through with your inch block or whatever and the screw compensator and compensate for any wobble in your screw
[02:54:38] <Valen> thats what google says
[02:55:13] <Guest796> thanks guys, I will go now and frig with it some more. Thanks!
[02:55:25] <Valen> you can install irc onto the computer itself
[02:55:32] <Guest796> Mama wants cheesecake, gotta go!
[02:55:59] <Guest796> oh yea? irc, I have a mac.
[02:56:31] <Valen> i meant onto the EMC computer
[02:56:41] <Valen> and there will be a buttload of irc clients for mac as well
[02:56:54] <Guest796> oh, no internet at the shop yet!
[02:57:04] <Guest796> later!

[02:58:45] <l0st1nsp4c3> yup
[02:59:06] <l0st1nsp4c3> and that's a shame cause I know nothing lol
[03:00:35] <l0st1nsp4c3> well i guess i'm gonna order my end mills same place i got my precision collet

[04:05:04] <Connor> So, get a Boring Head with a R8 Shank, or one with something like 3/4" straight shank and use a collet/tool holder ?
[04:05:52] -!- factor has quit [Read error: Connection reset by peer]
[04:07:03] <l0st1nsp4c3> ?
[04:08:06] <l0st1nsp4c3> who was that adressed to?
[04:08:14] <Connor> anyone.
[04:12:23] <l0st1nsp4c3> sorry no input on that from me
[04:12:31] <l0st1nsp4c3> i thought R8 Was a bridgeport only thing
[04:13:32] <l0st1nsp4c3> but i see everybody has copied them
[04:13:38] <Connor> My machine takes R8 Collets.. So, I can either go with a R8 Shank for the boring head, or use a 1/2" or 3/4" straight shank and use the appropriate collet.. and at some point use a Tormach Tool holder with it.
[04:14:08] <toastyde1th> use straight shank boring heads wherever possible
[04:14:38] <toastyde1th> there is no appriciable increase in rigidity by going solid R8 and you remove the ability to reasonably hold it in potential future applications
[04:15:32] <Connor> Except the one I'm looking at can have the shank removed and replaced with another one.. but yea.. I'm thinking straight shank and use a collet.
[04:15:49] <l0st1nsp4c3> isn't tormach
[04:16:00] <l0st1nsp4c3> the gang that gave the 2d scanning software via hd webcam
[04:16:51] <l0st1nsp4c3> http://www.buildlog.net/blog/2010/09/tormach-cnc-scanner/
[04:16:51] <Connor> No clue. Tormach I'm talking about makes a Tooling System that's nice for Quick changing or automated tool holder.
[04:16:57] <l0st1nsp4c3> i remember his video
[04:17:04] <l0st1nsp4c3> was on hackaday i think
[04:17:58] <l0st1nsp4c3> dunno if it'll interest any of you but i found it kewl

[12:22:24] <psha[work]> but it depends on type of drive
[12:23:04] <Maxxtr0> the driver is based on a single L298

[14:04:45] <Maxxtro> Basically it works, but the motor only makes a noise and doesnīt move. The frequency seems way too high for me... What could I do?
[14:06:08] <mazafaka> for stepper, use reasonably low frequency (feedtrate), check the jumpers on the driver (configure it)
[14:06:30] -!- Techrat has quit [Ping timeout: 260 seconds]
[14:08:40] <Maxxtro> Well I think I have to say that Iīm driving them directly; So the driver is a single L298 and EMC generates the waveform for the four phases of the motor.
[14:10:18] <Maxxtro> Everything I did until now is changing the stepgen mode to 9 und re"wiring" the ports
[14:13:42] <Loetmichel> Maxxtro: invest in some L297
[14:14:09] <Loetmichel> its cheaper than a second LPT because of lack of portpins ;-)

[14:15:15] <skunkworks> Maxxtro: can you lower the max velocity to something like really small and try again?
[14:15:31] <Loetmichel> besides: the L297 is capable of PWM for the motors, so you can feed the drivers with 40 volts and haf about 10 times the max speed than 5V
[14:16:03] <Maxxtro> Loetmichel: actually, the portpins are enough; i only have two motors and one enable signal for a laser
[14:16:11] <Loetmichel> ok
[14:16:30] <Loetmichel> but the part with the tenfold speed applies nontheless
[14:17:05] <Loetmichel> (if the motors are designt for 5V or less)
[14:17:14] <Loetmichel> designed
[14:17:20] <Maxxtro> skunkworks: i already did, yes. the frequency gets lower, but the motor doesnīt turn properly
[14:18:03] <Loetmichel> shit, i am dripping like fresh from the pool... it has ~30°c here and about 90% humidity
[14:18:06] <archivist_emc> Maxxtro, check wiring, dont accelerat to fast
[14:19:06] <Maxxtro> Loetmichel: speed doesnīt matter... of course using a l297 would be much easier, but now i got that far and so i really would like to get this thing running
[14:19:11] <Maxxtro> as it is
[14:19:20] <archivist_emc> I just got my 1945 Adcock and Shipley N1 horizontal mill cutting for the first time since I got the machine home :)
[14:19:53] <JT-Shop> archivist_emc: nice, got any photos of the mill?
[14:20:15] <pcw_home> cncbasher set the is_opendrain parameter for the corresponding GPIO bit
[14:20:18] <archivist_emc> Maxxtro, speed does matter, stepping at a rate above the motors cut in rate will just sit there and make a noise
[14:21:01] <pcw_home> cncbasher: set the IS_OPENDRAIN parameter for the cooresponding GPIO bit
[14:21:31] <pcw_home> oops
[14:21:32] <cncbasher> arh ok got it , i was thinking more along the lines of being specific for defined pins .
[14:21:46] <cncbasher> rather than generic
[14:22:05] <cncbasher> thaks again
[14:22:17] <pcw_home> made a early decision for all output modifiers to be pin specific
[14:22:30] <pcw_home> much simpler hardware wise

[15:43:46] <danimal_garage> hi John
[15:50:09] <danimal_garage> how goes it
[15:50:50] <anonimasu> well, if you have a reference tool eg, a probe.. the length never changes
[15:51:03] <anonimasu> and you wont have to re-set your tools in case your reference tool breaks or something
[15:51:17] <anonimasu> in practice I offset all my tools for new jobs off the work surface anyway

[16:33:04] <Maxxtro> srchivist: as far as i can see, theos ontime for each single phase is 1ms and the offtime is about one and a half ms
[16:33:30] <syyl> i think the thread on the arbor is a right hand
[16:33:56] <syyl> at least, all arbors i have used so far, had a right hand thread :D
[16:34:16] -!- Poincare has quit [Ping timeout: 260 seconds]
[16:35:41] <archivist_emc> Maxxtro, so you are trying to pulse above a steppers pull in rate, set the acceleration lower so you can get up to that speed (this depends on stepper size too)
[16:35:43] <skunkworks> the ones that I have used are right handed also
[16:35:56] <Connor> Okay, so, I asked last night, but, only got one response.. Looking at getting a boring head. Should I go with a R8 Shank, or one with a 1/2" or 3/4" straight shank and use with collet/tool holde.
[16:36:28] <syyl> got a r8 spindle?
[16:36:33] <cradek> R8 shank might be slightly more repeatable and give you slightly less stickout
[16:36:36] <archivist_emc> the shortest overhang and most solid
[16:36:39] <syyl> then a r8 woul d be more rigid
[16:37:33] <JT-Shop> archivist_emc: neat, what are you cutting in the photos?

[16:38:43] <archivist_emc> Maxxtro, yes
[16:39:53] <archivist_emc> skunkworks, I did use a long spanner and put it in back gear... effin tight

[16:41:33] <Connor> syyl: Yes, I have R8 Spindle. My thinking was, if I go with a TTS the a straight shank would be good.. looking at these boring heads, looks like you can change the shank out.. so.. maybe it's a mute point.
[16:41:57] <syyl> TTS?
[16:42:06] <Connor> Tormach Tooling System.
[16:42:09] <syyl> ah ok
[16:42:16] <syyl> that quickchangething?
[16:42:41] <Connor> Yes. You can also use it with a power drawbar and/or auto tool changer.
[16:43:05] <syyl> is there no TTS-R8 adapter?
[16:43:39] <cradek> TTS is 3/4 straight shank, so you use an R8 collet
[16:43:42] <Connor> TTS Has a R8 Collet that's been slightly modified so that their tool holders seat against the base of the spindle.
[16:44:06] <syyl> mh ok
[16:44:51] <Connor> http://www.tormach.com/Flash/TTS_small.html
[16:45:23] <syyl> interesting system
[16:45:53] <syyl> even if i would prefer a int-taper
[16:46:20] <Connor> a what ?
[16:46:24] <skunkworks> Connor: you have a tormach mill? or just the tooling on your mill?
[16:46:52] <syyl>
[16:46:56] <syyl> taper like that
[16:46:56] <Connor> I have nothing yet.. just a G0704 with R8 Spindle.. I'm looking at the TTS
[16:47:13] <syyl> but the tts is interesting as it converts a existing spindle
[16:47:22] <Connor> syyl: Ah. Okay.
[16:48:16] <Connor> For what I'm doing, the 3/4 straight shank for a boring head would be fine.. I would just use my 3/4" Collet and be done with it.
[16:49:34] <syyl> oh, there is also a tts for morse taper spindles
[16:50:10] <Connor> Yea.

[17:11:47] <JT-Shop> if a stepper is rated at 2.8 A/phase how much current will it draw?
[17:12:59] <IchGuckLive> at full step or half
[17:14:06] <JT-Shop> full step
[17:14:24] <IchGuckLive> jt i advise that the Watts count
[17:14:41] <IchGuckLive> 1W=1V+1A
[17:14:46] <IchGuckLive> *
[17:14:56] <IchGuckLive> 1W=1V*1A
[17:15:40] <JT-Shop> does each phase draw 2.8 amps or is that the total amp draw of the stepper?
[17:15:46] <IchGuckLive> so at 24Vtimes 2.8A you are at 67 100W will do it

[20:22:59] <mazafaka> I grind the cutter and ...
[20:23:16] <mazafaka> oh...
[20:23:25] <anonimasu> andypugh: well, my encoders are serial with rs485, and I didnt see any way to do that with hal..
[20:23:37] <andypugh> So, you always make sure that you keep 0 for both offsets on that tool, and adjust the coordinate system to suit that.
[20:23:56] <andypugh> anonimasu: You would need to write a new component.
[20:24:16] <mazafaka> OK, will try to read it about on linuxcnc.org as well.
[20:24:21] <andypugh> anonimasu: It only needs to run in the servo thread, so you probably have the time.

[20:24:32] <andypugh> Hi Isssy
[20:25:25] <isssy> hi
[20:26:17] <andypugh> mazafaka: The way I work is to turn an OD and face with the 0 tool, then set the G54 coordinate system to measured OD and 0 for Z. Then any other tool you touch-off to the Tool Table instead of G54. (with a test cut, is simplest). Then those offsets stay the same until you move the tool in its holder, or regrind it.
[20:26:36] <anonimasu> andypugh: is it extremely heavy to use rs232 from a component?

[20:27:02] <andypugh> I don't know. I have never tried.
[20:27:51] <andypugh> I don't know for sure that it is even possible.
[20:28:01] * anonimasu wishes that cradek will show up
[20:28:05] <mazafaka> andypugh: as if you worked manually, thanks for the explanation.
[20:28:10] <andypugh> What is your PC-side hardware?
[20:28:23] <anonimasu> i were thinking userspace and then just setting up my commutation data at startup
[20:29:00] <anonimasu> because I already have the stuff written like that to test my encoders
[20:29:33] -!- mrsunshine has quit [Ping timeout: 240 seconds]
[20:29:37] <andypugh> Any reason that the Userspace code can't run in kernel space?
[20:30:24] <anonimasu> well, it's c# for now, because it saved me the trouble, and it crosscompiles with the default gnome included stuff

[20:30:25] <alexander> JT-Shop: werd, I'm going to get a D525MWV and call it a day
[20:31:01] <anonimasu> I think the modbus stuff might be usable
[20:31:13] <jthornton> alexander: make sure you get the right memory for it
[20:31:27] <jthornton> it's 204 pin
[20:33:40] <anonimasu> is there a big difference between a hal userspace component and a realtime?
[20:33:55] <anonimasu> http://wiki.linuxcnc.org/emcinfo.pl?VFD_Modbus
[20:34:58] <andypugh> anonimasu: Well, a realtime module has to quit in finite (short) time.
[20:35:15] <alexander> jthornton: yah, I have laptop memory to fit it already
[20:35:41] <andypugh> You end up using state machines a lot, so that it can fall-through, and carry on where it left off next call.
[20:36:59] <anonimasu> andypugh: well, there's a 10ms max response time
[20:37:39] <anonimasu> it's pretty much only used to set up commutation I think..
[20:37:50] <anonimasu> then there's sin/cos output for the positioning
[20:38:48] <anonimasu> so, the issue is that the component needs to send a message to the encoder, and read it out the next call process it and stick it as a variable
[20:40:41] -!- pjm__ [pjm__!~pjm@uhfsatcom.plus.com] has joined #emc
[20:41:10] <anonimasu> looks like, i need a realtime component to make a pipe to my userspace code
[20:41:29] <anonimasu> or make my userspace code grab a hal pin for when it's supposed to give data...
[20:42:14] * anonimasu hopes that someone with knowledge will chime in
[20:42:38] <andypugh> anonimasu: Ah, in that case, ignore nearly everything I have said
[20:43:12] <andypugh> anonimasu: Your userspace code should be able to create pins in HAL
[20:43:41] <andypugh> All it needs to do is keep the value on that pin as up-to-date as it can
[20:43:51] * anonimasu ponders python + calling the program he already made
[20:43:56] -!- pjm has quit [Ping timeout: 260 seconds]
[20:44:13] <anonimasu> unless there's a good way to do serial comm in python
[20:44:19] <anonimasu> and easy way to do bitwise math
[20:47:30] <andypugh> anonimasu: I _think_ that the existing code should be able to call rtapi_hal_pin_newf and create itself a pin.
[20:47:56] -!- syyl_ has quit [Remote host closed the connection]
[20:48:23] <andypugh> Then just start up your existing code with loadusr in the HAL file, and it ought to work.
[20:48:43] <andypugh> hal_input is a really good example of a Userspace program with HAL pins.

[20:50:04] <andypugh> But maybe look at Shuttlexpress, as that is in C. http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/hal/user_comps/shuttlexpress.c;h=6d9128ff0408980e3315b04a4a85df16e2f9104e;hb=HEAD
[20:51:00] <andypugh> I think it might be as simple as #include hal.h and then creating pins.

[23:09:57] <andypugh> The last guy who expected to have his machine back up in a week is still down after 4 months. The annoying thing is that I think he went Mach3 because the Mach3 guys said "A week? No trouble" and I said "Hmm, plan on a month for that conversion with EMC2".
[23:10:21] <alexander> ah
[23:10:26] <alexander> what was his big hangup?
[23:13:31] <andypugh> Driver supply, and brother in law not doing the wiring.
[23:14:13] <alexander> ah
[23:14:17] <andypugh> And converting a velocity servo, linear scale-feedback servo machine to Mach3 being a difficult and stupid plan.
[23:14:54] <alexander> I feel like I understand the wiring/driver infrastructure pretty well,.. I guess we'll see what happens when I get everything.
[23:15:54] <alexander> I ended up getting a Meanwell 10 amp 48 volt supply, 3 PK266-02A steppers, and a G540
[23:16:18] <andypugh> I reckon I could do that in a day :-)

[23:16:52] <andypugh> A week sounds reasonable for a stepper machine.
