[02:13:26] <DJ9DJ> moin
[02:52:07] <IchGuckLive> morning all Snow in arizona late Feb the climat is changing plant starts later
[06:47:17] <jthornton> anyone have a list of HAL pins from a 7i76?
[07:36:28] <R2E4_awy> A there wiring diagrams available for 5i25 and 7i77?
[07:36:50] <R2E4_awy> Are there it was suppose to read....hehe
[07:37:47] <mhaberler> jthornton: yes, will look into it
[07:39:19] <Tecan> wonder whats on the agenda today :)
[07:41:15] <mhaberler> jthornton: it's been a while - had it running but forgot which config; have a link somewhere?
[07:44:28] <jthornton> mhaberler, a link to what?
[07:48:18] <mhaberler> a 5i25+7i76 config
[07:48:26] <jthornton> ah ok
[07:49:41] <jthornton> http://linuxcnc.org/index.php/english/forum/49-basic-configuration/26211-sample-configurations
[07:53:17] <R2E4_awy> Is it better to supply 5v seperate from the computer to keep it isolated?
[07:53:50] <jthornton> only needed if you have lots of encoders like on a 7i77 usually
[07:54:29] <R2E4_awy> I'm putting three encoders on a 7i77.
[07:54:53] <R2E4_awy> AH, I'll just add the 5v PS, its nothing and it will keep it isolated.....thanks
[07:56:30] <mhaberler> jthornton: see mail
[07:56:47] <jthornton> ok
[08:01:31] <mhaberler> forum seems wedged - internal server error on
http://www.linuxcnc.org/index.php/english/forum/30-cnc-machines/26178-cincinnati-axis-spindle-question?limitstart=0#30152
[08:02:10] <mhaberler> ah, temporary
[08:07:31] <jthornton> mhaberler, thanks for the pin list
[08:07:40] <mhaberler> sure
[10:18:12] <R2E4> Can I use the onboard PPORT with a 5i25 card?
[10:18:29] <pcw_home> yes
[10:20:27] <R2E4> actually I want to use the cnc4pc mpg2 pendant
[10:32:16] <R2E4>
[10:39:27] <JT-Shop> IIRC you need the breakout thingy for that one
[10:45:40] <NeedingHelp945> hello
[11:35:10] <xxoxx> hello
[12:00:12] <Tom_itx> hey andypugh
[12:00:34] <andypugh> Hi
[12:00:45] <Tom_itx> i think i fixed the post
[12:01:08] <xxoxx> does linuxcnc run on raspberry pi ?
[12:01:09] <Tom_itx> i uploaded 2 new files that should give you .5mm retract after each move
[12:01:36] <Tom_itx> check them carefully before you push 'GO' and walk away :D
[12:02:34] <andypugh> xxoxx: A bit.
[12:02:41] <Tom_itx> andypugh, here's the link in case you need it again:
http://tom-itx.dyndns.org:81/~webpage/emc/andyp/
[12:02:57] <andypugh> I stil have the window ope L-)
[12:03:25] <Tom_itx> ok
[12:03:34] <Tom_itx> just refresh and you'll see 2 new files
[12:04:03] <Tom_itx> you may wanna change the Tool number and H offset
[12:05:39] <xxoxx> i am still using mach3, thinking about trying out linuxcnc
[12:06:03] <xxoxx> is "Digital Machinist" the magazine worth getting ?
[12:07:10] <IchGuckLive> xxoxx: you are here the best to be for heven help
[12:07:46] <IchGuckLive> xxoxx: where are you from USA Europ asia
[12:07:56] <xxoxx> ASIA/USA
[12:08:13] <xxoxx> you from Germany ?
[12:08:18] <IchGuckLive> so did you ever work with linux
[12:08:21] <IchGuckLive> yes i am
[12:08:30] <xxoxx> yeah. I was a Linux dev
[12:08:37] <IchGuckLive> so NP
[12:08:40] <xxoxx> Ja Ja Ja
[12:08:48] <IchGuckLive> did you already install the livecd
[12:08:49] <xxoxx> :)
[12:09:13] <xxoxx> Not yet. Just downloaded it, haven't installed it.
[12:09:27] <xxoxx> Trying to come up with a computer to put it on.
[12:09:31] <andypugh> I wouldn't suggest the Pi as the ideal platform for LinuxCNC at the moment. It lacks CPU, basically. However it does work.
[12:09:40] <xxoxx> Right.
[12:09:44] <IchGuckLive> what are you trying to drive xxoxx
[12:09:56] <andypugh> MIni-ITX Atom boards are very popular and work well
[12:09:57] <xxoxx> 4-axis CNC mill
[12:10:12] <xxoxx> mainly aluminum cutting
[12:10:13] <IchGuckLive> stepper or servo
[12:10:20] <xxoxx> stepper for now. upgrading to servo this year
[12:10:34] <IchGuckLive> so the mashine is already working
[12:10:39] <IchGuckLive> on mach3
[12:10:48] <andypugh> Probably start with a Mini-ITX and parallel port. (maybe even dual-booth the Mach3 machine?)
[12:10:54] <xxoxx> andypugh, indeed. Mini-ITX + Atom, build a small but full-size rig
[12:11:25] <IchGuckLive> i woudt not go for that amond of money
[12:11:40] <IchGuckLive> get you a pold PC for less then 50 box
[12:11:41] <xxoxx> IchGuck, yes. currently I am driving it with Sempron machine running XP + Mach3
[12:12:05] <IchGuckLive> as aluminium needs no 10m/min
[12:12:06] <xxoxx> AMD Sempron
[12:12:19] <IchGuckLive> i use old ibm A50p
[12:12:21] <xxoxx> ok
[12:12:30] <IchGuckLive> and can go beond 3m/min easy
[12:12:52] <xxoxx> 3m / minute, that's fast
[12:12:58] <xxoxx> I am doing like 20mm / min
[12:13:07] <IchGuckLive> xxoxx: there is a autostepconf
[12:13:19] <IchGuckLive> so only get you numbers in and you are done
[12:13:42] <IchGuckLive> no need for calculations or wear things
[12:13:51] <xxoxx> ok
[12:13:54] <IchGuckLive> xxoxx: can you read german
[12:13:59] <xxoxx> Ja. Ein bischen
[12:14:42] <xxoxx> learned 5 years German. Forgot most of it due to not using it very much.
[12:15:18] <xxoxx> Franz Kafka is the most complicated work I ever read. Only half understood it though.
[12:15:24] <IchGuckLive> xxoxx:
http://www.youtube.com/watch?v=IRp2dwu05BI here is my chanel to get the main work
[12:15:31] <xxoxx> Danke
[12:15:52] <IchGuckLive> NP
[12:24:55] <xxoxx> thinking about building a mini EDM
[12:25:53] <rizo> I have servo driver (with parameters not set yet) and i want to home this axis using index. I can not home the axis because i get the following error, and can not set the PID parameters because i can not control the machine until it is homed.
[12:26:35] <rizo> Can i somehow override the following error during homing?
[12:26:37] <t12> i got that maxnc10 running
[12:26:40] <andypugh> xxoxx: Wire or plunge? There are tecnical problems with wire-edm and LinuxCNC (it doesn't know how to reverse back up the path)
[12:26:44] <t12> barely
[12:27:00] <xxoxx> plunge
[12:27:08] <xxoxx> doing very small scale work
[12:27:34] <andypugh> xxoxx: You can probably do that using offsets in HAL to reverse then.
[12:27:43] <cradek> rizo: just position it manually: set your homing velocities to zero and it'll call the current position home.
[12:27:58] <xxoxx> thinking about using hollow needle as the cutting tool
[12:28:17] <andypugh> rizo: The simplest way is to short-circuit the f-error loop, but that might not be so smart.
[12:28:55] <cradek> you really want f-error check while tuning. it'll kill your amps if you get big oscillation or runaway.
[12:29:05] <andypugh> rizo: NO_FORCE_HOMING in the INI is another option.
[12:29:26] <xxoxx> hypodermic needle as cutting tool for EDM
[12:29:43] <xxoxx> cutting jewel-size work pieces.
[12:29:52] <xxoxx> pico-scale metal work
[12:29:54] <andypugh> Should work. I have used brass tube.
[12:30:18] <xxoxx> andypugh, thanks. good to know that. I am just in the thinking stage.
[12:31:51] <xxoxx> maybe build a tiny desktop machine
[12:33:40] <andypugh> How tiny?
http://www.ebay.co.uk/itm/2-phase-4-wire-stepper-motor-MCU-learning-Board-6mm-Canon-micro-step-motor-/160969068371?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item257a810f53
[12:34:00] <JesusAlos> hi
[12:34:02] <xxoxx> making metal parts for small tank models. clock-size parts
[12:34:08] <xxoxx> https://www.youtube.com/watch?v=1Beh7ucqsuk
[12:34:11] <xxoxx> like this
[12:34:31] <xxoxx> torsion bars, metal gear box, clutch, brake, gun parts, etc
[12:34:44] <xxoxx> clock-size parts
[12:34:52] <xxoxx> not as small as watch
[12:35:31] <xxoxx> wow... that's a tiny step-motor
[12:36:41] <rizo> is there some axis.home-sw output - i need to signal to bldc.init to start home sequence. Which one should i use then, the bldc home sequence or the axis home sequence?
[12:37:35] <pcw_home> BLDC home has nothing to do with Axis home
[12:38:04] <andypugh> In fact, bldc-init should be avoided if at all possible :-)
[12:38:29] <rizo> arent they all connected through index-enable pin/signal
[12:38:59] <andypugh> Not necessarily.
[12:39:23] <pcw_home> sequence is something like machine-on --> BLDC init (motor rotor homed so controllable)
[12:39:25] <pcw_home> then normal axis home
[12:40:35] <pcw_home> BLDC only looks at the index enable signal when doing its init (QI mode)
[12:41:17] <rizo> i have to start the i have to somehow tell the bldc. to init otherwise it wil not latch the encoder value at index-enable
[12:42:01] <pcw_home> yes normally machine on starts the BLDC init process (for mode that need it)
[12:43:03] <andypugh> rizo: What sort of motor is it? Do you have Hall signals?
[12:43:11] <rizo> so i dont need to use the home button in axis UI
[12:43:31] <rizo> linear (anorad)
[12:44:23] <pcw_home> Linear motors often do not have hall signals
[12:44:44] <rizo> I have encoder
[12:44:51] <rizo> and index signal
[12:45:17] <rizo> no hall sensors
[12:47:40] <pcw_home> andypugh: BLDC must drive index enable in QI mode so does this interfere with homing on index?
[12:49:10] <pcw_home> plain old Q mode might work if theres a problem with QI and axis homing on index
[12:49:36] <rizo> what is QI mode?
[12:49:51] <rizo> i have bldc qi
[12:50:02] <rizo> if this is whyt you mean?
[12:50:11] <pcw_home> yes
[12:53:48] <andypugh> Hmm, so bldc needs to drive index-enable, and so does the homing sequence.
[12:54:02] <andypugh> It is a bidirectional pin, so it might be OK.
[12:54:59] <andypugh> But you would then normally connect the bldc-init pin to machine-is-on
[12:55:16] <rizo> but i have to start the home at axis (set the search_vel to 0) and bldc at same time?
[12:55:43] <andypugh> I don't think so.
[12:56:23] <andypugh> You would home the motor immediately, then find the home switch once the motor is working. The motor won't work until bldc has init-ed.
[12:56:28] <rizo> I did connect the bldc-init to axis.0.amp-enable-out but it is switched off because of following error.
[12:57:29] <andypugh> Hmm, yes, I have been here before.
[12:57:40] <pcw_home> machine on is probably more appropriate
[12:58:37] <rizo> Ok, but machine on is power on, i probably need a bit of pause?
[12:59:26] <pcw_home> If machine-on powers the drives. perhaps
[13:00:19] <andypugh> The way to do this (I just remebered) is to put the bldc comoponent between the button and machine-on.
[13:00:24] <andypugh> Let me work out the pin names.
[13:00:51] <Tom_itx> andypugh, we need pics of your mold making progress now
[13:00:58] <andypugh> So, you turn on the machine, and then the bldc components init, and then the init-done pin is used to enable the acis.
[13:01:35] <IchGuckLive> yeah the position in hal is realy importend
[13:01:40] <Tom_itx> andypugh, if the .75 stepover is too much/little i can change that pretty easy
[13:02:19] <andypugh> It's wood, so should be OK (I decided the model-board was too precious :-)
[13:02:28] <Tom_itx> heh
[13:03:06] <Tom_itx> i don't remember if i added a second cleanup pass either but you can copy the last pass if not
[13:03:29] <Tom_itx> on metal i try to run a .010" or so cleanup on the last run
[13:09:56] <andypugh> rizo: I am getting slightly confused about how I did this previously.
[13:10:49] <andypugh> I think you only get f-errors with the machine on.
[13:11:18] <andypugh> So, you need to start the alignment sequence as soon as you go out of e-stop. Which doesn't actually sound ideal.
[13:11:23] <rizo> machine on is machine-power?
[13:11:54] <andypugh> I am talking in terms of the Axis UI, so that is the F2 button.
[13:12:05] <andypugh> Which sets the amp-enable pins
[13:12:38] <rizo> f2 amiidiatly turns of the machine beacuse of following error.
[13:12:47] <andypugh> Yes.
[13:13:04] <rizo> I tried the estop, and i can home the bldc, but not axis.
[13:13:35] <andypugh> I don't understand what you mean.
[13:13:47] <rizo> i wired the bldc-init to estop
[13:13:54] <andypugh> Ah, OK.
[13:14:03] <andypugh> And init-done goes true?
[13:14:22] <rizo> Just bldc, but not axis.
[13:14:43] <rizo> yes
[13:14:54] <andypugh> What happens when you try to home the axis?
[13:15:29] <rizo> nothing, the x value is set to 0
[13:15:37] <rizo> which is wrong.
[13:15:52] <pcw_home> I think you want F2 to start the BLDC init and BLDC init done to enable motion
[13:15:56] <andypugh> Is 0 the home position?
[13:16:22] <rizo> I cant, because the following error shut the F2
[13:16:35] <pcw_home> (so ferrors are not possible during BLDC init)
[13:16:36] <rizo> and the motor doesnt index
[13:17:06] <andypugh> pcw_home: Just reading up on the motion.motion-enabled pin...
[13:17:07] <pcw_home> thats because you are using the GUI to enable motion, this has to be removed
[13:17:28] <IchGuckLive> why dont you staart the blcd by pyvcp and get the init to a led
[13:17:37] <pcw_home> GUI-ON --> BLDC-INIT --> MOTION-ENABLE
[13:18:06] <rizo> I can do that, but the position in axis will not be homed...
[13:18:28] <andypugh> rizo: Have yoiu set up a homing sequence and hominf switches?
[13:18:50] <pcw_home> GUI-ON --> BLDC-INIT --> MOTION-ENABLE --> HOME
[13:19:02] <andypugh> Have you netted axis.0.index-enable to the encoder counter?
[13:19:22] <rizo> i set search/latchvel to 0 and use_index = YES
[13:19:33] <andypugh> That won't work
[13:19:47] <andypugh> With search-vel at zero it doesn't search.
[13:20:01] <rizo> i have wired the index-enable
[13:20:18] <andypugh> Yes, but search-vel = 0 turns off homing.
[13:21:04] <andypugh> (or, rather, the axis sets wherever it happens to be when asked to home as home.
[13:21:43] <andypugh> I am assuming that you want to search for a physical home-switch then home to the nearest index?
[13:21:48] <rizo> I changed the search_velocty to 5., but still the x position in axis is not set to 0 when homed
[13:22:12] <andypugh> Does the axis move when looking for the home?
[13:22:20] <rizo> yes
[13:22:44] <rizo> there is yust one index (why nearest)
[13:23:13] <andypugh> I was imagining there might be many indexes, like a linear scale has.
[13:25:06] <rizo> there are many indexes (i actually don't understand why there are so many), but i dont use them, i just use the last one.
[13:25:56] <andypugh> Is there a physical switch too?
[13:26:13] <rizo> no
[13:26:16] <pcw_home> Is the encoder position output HAL pin cleared by index?
[13:26:17] <andypugh> (And what is the latch velocity set to?)
[13:26:27] <rizo> optical index signal, detected by fpga
[13:26:39] <rizo> to 0
[13:27:10] <andypugh> Sorry, I am not all that familiar with the details of homing to index.
[13:27:25] <pcw_home> Can you check this? (set index enable true by hand, move carriage by hand to index)
[13:28:13] <pcw_home> encoder position should be set to 0 and index enable pin cleared
[13:28:18] <rizo> i did that, that trigers the index-done
[13:28:32] <rizo> but just for bldc, not for axis UI
[13:29:06] <andypugh> That is the answer to a different question...
[13:29:07] <pcw_home> is the encoder count cleared in axis?
[13:29:14] <rizo> No
[13:29:23] <rizo> Because i did not pres the f2
[13:29:35] <rizo> if i prees the f3 i get the following error
[13:29:45] <rizo> if i press the f2 i get the following error
[13:30:04] <andypugh> So, bldc inits when you go out of e-stop.
[13:30:17] <rizo> and the power is switched of, so i assume the index-enable pi is not monitored by the axis any more
[13:30:19] <andypugh> But if you then press F2 the machine f-errors?
[13:30:26] <rizo> yes
[13:30:42] <andypugh> That makes no sense.
[13:31:08] <andypugh> I thought you said that the carriage moved when you pressed "home"?
[13:31:19] <andypugh> But you can't press "home" without the machine being on?
[13:32:46] <rizo> If i power on and move the motor (by hand or electrically) i get the followng error.
[13:33:02] <andypugh> Is your PID tuned at all?
[13:33:17] <rizo> I can home bldc only if i wire it to e-stop.
[13:33:21] <andypugh> Moving the motor by hand _should_ give an f-error
[13:33:32] <rizo> No... that was my initial problem :)
[13:33:41] <andypugh> Can you jog?
[13:33:41] <rizo> i can not tune pid if machine is not homed
[13:34:12] <andypugh> You need the bldc to be inited. You absolutely do not need to be homed.
[13:34:17] <pcw_home> YOu can do some tuinig just by jogging
[13:34:31] <pcw_home> no homing needed
[13:34:45] <rizo> i can not use bldc until it is homed
[13:35:03] <pcw_home> different home
[13:35:14] <rizo> i can not use bldc until it is init
[13:35:29] <andypugh> This is true. But is unrelated to homing the axis
[13:37:28] <pcw_home> thats true and init-done can be used to drive motion.enable (so you dont get ferrors when doing BLDC init)
[13:38:20] <rizo> But i still dont understand, how can i tune the PID if following error stops the machine very time.
[13:38:38] <pcw_home> make the ferror bigger
[13:38:39] <rizo> Should i icrease the following error limit - ist there this option?
[13:38:46] <pcw_home> yes
[13:39:03] <rizo> ok, will try this
[13:39:35] <pcw_home> normally should be set for an inch or so for tuning
[13:39:52] <pcw_home> (so a complete runaway is stopped)
[13:45:00] <alan_1> Does anyone know if I can compile motmod.ko by itself without compiling the entire linuxcnc source? or is this not realistic
[13:46:11] <andypugh> alan_1: There may be a way, but I suspect it would take far longer to find it than to just compile everything
[13:46:57] <cradek> andypugh: not realistic. why do you think you want to do that?
[13:47:07] <cradek> oops, alan_1: ^
[13:48:12] <andypugh> I was about to take umbrage! (But can't remember where I left it)
[13:48:20] <cradek> ha
[13:48:26] <alan_1> I'd like to get non-trivial kins to honour soft-limits and stop jogs when probe is tripped.
[13:49:05] <cradek> you might want to try the ja3 development branch, it has a better jog planner
[13:49:52] <cradek> do you want world space (rectangular solid) soft limits or joint space soft limits?
[13:50:30] <alan_1> world mode. everything seems to work fine in joint mode.
[13:50:42] <andypugh> (And, if this is a shopping list, rectangular is too limiting, it should be an STL or similar format for the limit-shape)
[13:50:48] <cradek> do try ja3
[13:51:26] <alan_1> is there a central location for ja3 info? I didnt see anything on my searched
[13:51:27] <cradek> andypugh: yeah just put it on the action item list and assign it to one of our hired flunkies
[13:52:15] <cradek> the jog planner could ask kins whether the desired endpoint is valid, and the implementation of that could be kins-specific
[13:52:19] <andypugh> Hired flunkies are expensive, can't we use slaves
[13:53:03] <cradek> andypugh: we'd have to time-machine ourselves to before 1867 but they may not know computers very well

http://psha.org.ru/irc/%23linuxcnc/2013-02-26.html
[13:54:15] <andypugh> According to the bible it's OK to have slaves as long as they come from neighbouring nations.

[14:12:29] <pcw_home> No, but you have to be careful with terminology here
[14:13:13] <pcw_home> an external input pin is a a HAL out pin
[14:13:14] <pcw_home> and an external output pin is a HAL in pin
[14:14:10] <cradek> JesusAlos: please back up and say what you are trying to accomplish
[14:14:11] <JesusAlos> Ok
[14:15:23] <cradek> alan_1: no information, but source:
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=shortlog;h=refs/heads/joints_axes3
[14:17:30] <alan_1> cradek: Thank you very much
[14:17:56] <JesusAlos> I need create a button in axis. It must do two functions. His name pause button
[14:18:05] <cradek> alan_1: welcome, hope it has a better starting point for your changes
[14:18:16] <JesusAlos> one pause programm execution
[14:18:24] <JesusAlos> Two stop spindle
[14:19:09] <cradek> so backing up still further to try to understand the problem you are solving: do you want the spindle to always stop when you pause?
[14:19:16] <JesusAlos> Create a second button with two functions start programm execution and start spindle
[14:19:50] <JesusAlos> yes, I need stop spindle when push pause button
[14:19:57] <cradek> ok, you're still asking about an implementation. please describe your original problem or goal
[14:21:52] <cradek> it sounds like maybe you want your spindle-enable output to come from something like motion.spindle-forward AND NOT halui.program.is-paused
[14:21:53] <JesusAlos> is a bit long to explain, but basically, I have a hot wire cutting machine
[14:22:12] <JesusAlos> and spindle output connect to hot wire
[14:22:27] <cradek> ok
[14:22:46] <JesusAlos> yes
[14:23:06] <cradek> sorry for interrupting, please keep describing the problem
[14:24:13] <JesusAlos> the problem is if I pause the program execution spindle (My hot wire) still on
[14:24:34] <JesusAlos> so Foam burn
[14:25:33] <cradek> why do you pause it?
[14:26:25] <cradek> if you set feed override to 0% you have the same problem, or if there is G4 in the program, or feed rate is programmed very slow
[14:26:27] <JesusAlos> the same reason like some people pause his engrave machine
[14:26:31] <JesusAlos> for example
[14:27:12] <cradek> so should the wire turn off whenever there is no motion, or only when you select pause
[14:28:30] <JesusAlos> only when push pause || button
[14:29:21] <cradek> then my earlier guess is probably what you want
[14:30:32] <cradek> you should verify what halui.program.is-paused does for single stepping
[14:36:10] <JesusAlos> and connect with spindle pin?
[14:36:34] <JesusAlos> spindle hal pin?

[15:22:46] <Jymmm> WHAT THE FUCK?!
http://radio.foxnews.com/toddstarnes/top-stories/health-dept-homeless-cant-eat-deer-meat.html
[15:42:31] <cradek> eh, more calling your representative and working on getting bad laws changed, less fox news manufactured outrage pls, LA
[15:43:41] <cradek> also less FOLLOW TODD ON FACEBOOK FOR CULTURE WAR NEWS ENDORSED BY SARAH PALIN, pls
[15:44:49] <Jymmm> lol, I can't help the FB/Twitter crap =)
[15:45:06] <Jymmm> As far as Fox goes, eh.
[15:45:21] <Jymmm> cradek: IT WASN'T THE POINT MISTER =)
[15:45:28] <cradek> and since when was a health dept regulation "culture war"
[15:45:44] <cradek> sorry, I watch for bs everywhere
[15:46:17] <Jymmm> There will always be bs, that's what you have to sift thru to find the gems
[15:46:41] <r00t4rd3d> whats the command again to send a axis home like g28 x0 or something
[15:47:11] <cradek> if you mean to the unoffset machine zero (not the same as homing), use g0 g53 x0
[15:47:24] <r00t4rd3d> no just to send back to 0
[15:48:01] <r00t4rd3d> i know it was g** x0
[15:48:15] <cradek> g0 g53 x0
[15:48:33] <r00t4rd3d> that wasnt what i been using
[15:49:25] <r00t4rd3d> i think JT-Shop told me
[15:50:24] <cradek> I've seen people use G91 G28 X0 but that's roundabout, leaves you in unwanted G91 mode, and may not even go to unoffset 0 depending on your setup
[15:50:39] <cradek> so you really want g0 g53 x0
[15:50:59] <r00t4rd3d> ill try it
[15:51:34] <r00t4rd3d> if it breaks stuff, im coming over and smashing your clocks
[15:52:51] <r00t4rd3d> sometimes when i hit the estop, i like to send the axis's back to where they started
[15:53:17] <r00t4rd3d> i click that mri tab g28 x0 y0
[15:53:23] <r00t4rd3d> i think it was 28
[15:53:25] <cradek> you'll forgive me for not answering your questions anymore
[15:53:32] <r00t4rd3d> lol
[16:25:45] <andypugh> I like this:

[17:32:39] <JesusAlos> sorry
[17:32:41] <JesusAlos> yes pastebin
[17:33:27] <andypugh> Is there a value on spindle-rpm-filtered?
[17:34:17] <JesusAlos> Where i can see that? In show HAL configuration?
[17:34:33] <andypugh> Yes, or a halmeter
[17:37:27] <JesusAlos> no found pin in Show HAL Configuration
[17:37:37] <andypugh> because it is a signal
[17:38:26] <JesusAlos> ok
[17:38:29] <JesusAlos> is 0
[17:38:41] <andypugh> Have you linked it to a source?
[17:39:08] <andypugh> something like net spindle-rpm-filtered lowpass.0.out ?
[17:39:11] <JesusAlos> only this line net spindle-rpm-filtered => pyvcp.spindle-speed
[17:39:16] <JesusAlos> in .hal file
[17:40:27] <andypugh> spindle-rpm-filtered is just a signal name. It needs a source. All you have done so far is create a signal called spindle-rpm-filtered and connect it to the PyVCP. There is nothing writing to the signal.
[17:41:25] <andypugh> The firs thing after the net command is a signal name. You can choose any names you want. None of them exist until your HAL file creates them.
[17:43:26] <JT-Shop-2> almost
[17:45:24] <JT-Shop> I think my enternet switch died
[17:49:09] <Valen> i hate it when that happens
[17:49:15] <Valen> i have a pile of 3 on the floor here
[17:49:31] <Valen> when one dies i put a new one on top of the old one
[17:50:46] <JT-Shop> sometimes they come back to life
[17:53:14] <JesusAlos> Don't found signal that show the speed spindle
[17:53:32] <JesusAlos> the most similar i found is override spindle
[17:53:47] <andypugh> You have a spindle encoder?
[17:53:49] <JT-Shop> motion.spindle-speed-out
[17:54:01] <andypugh> or encoder.N.velocity
[17:54:03] <JesusAlos> no ncoder
[17:54:36] <andypugh> Not much point having a spindle speed display if you aren't measuring spindle speed, really.
[17:54:45] <JT-Shop> aye
[17:54:47] <tjb1> r00t4rd3d: I got my pendant painted, not as nice as the sharpie but it doesnt come off
[17:55:41] <JesusAlos> motion.spindle-speed-out is 0
[17:55:57] <JesusAlos> no change when start
[17:56:04] <andypugh> Right, time to wash the wood dust out of my hair (watch the video, you will understand) and then snooze-time.
[18:00:13] <JT-Shop> goodnight Andy
[18:00:34] <JesusAlos> I follow the steps of Andy
[18:00:38] <JesusAlos> GN
[18:00:42] <JesusAlos> Thank
[18:00:55] <JT-Shop> say goodnight Gracie
[18:03:14] <tjb1> Hello all!
[18:05:10] <L84Supper> 4 hours to drive 40 miles today, sheesh...
[18:05:25] <L84Supper> and only 2-3 inches of snow
[18:05:32] <JT-Shop> hello tjb1
[18:05:43] <tjb1> How are you JT-Shop
[18:06:03] <JT-Shop> doing good, just working on the log splitter
[18:06:32] <tjb1> You make some cool projects…where do I get a job like this?
[18:07:18] <JT-Shop> http://imagebin.org/248261
[18:07:31] <JT-Shop> well the splitter is for me to use
[18:07:45] <tjb1> Is that a slip roll in the back right?
[18:07:54] <JT-Shop> it took me 44 years to get this job
[18:08:11] <JT-Shop> yea, a 3 in 1 sheet metal machine
[18:08:23] <tjb1> What gauge can you roll
[18:09:02] <JT-Shop> depends on the width but not much with that little thing, maybe 16 gauge
[18:11:16] <JT-Shop> 22 gauge for the slip roll and brake and 28 gauge for the shear
[18:11:26] <tjb1> That's like tinfoil :(
[18:11:57] <tjb1> My idea for fireplace rings went down unless I can find a way to make a circle with like 1/16
[18:12:16] <JT-Shop> how tall?
[18:12:40] <tjb1> Maybe 12"?
[18:12:44] <JT-Shop> why make rings? why not hex shaped?
[18:13:07] <JT-Shop> depending on your design some may poke out when you try an roll it
[18:13:32] <JT-Shop> if you had a design on each flat then bent them to form a hex you would be different
[18:13:51] <tjb1> Well even a brake for 1/16 is pretty expensive
[18:14:07] <JT-Shop> or make them fit together like cattle panels
[18:14:25] <JT-Shop> do you have an H frame press?
[18:14:35] <tjb1> I guess if I "serrated" it with the plasma you could almost bend it by hand
[18:14:38] <tjb1> Yes
[18:15:01] <JT-Shop> you could rig up something to resemble a press brake for the H press
[18:16:06] <tjb1> I still have to finish the hal for the thc a-d
[18:16:09] <tjb1> too busy with school
[18:16:57] <JT-Shop> don't want to get distracted from your studies
[18:17:12] <tjb1> Well my dad keeps harping on me to get it running again :P
[18:18:31] <JT-Shop> there is always nights and weekends
[18:18:54] <tjb1> I dont get home until friday at like 8-9pm and leave sunday at 3pm
[18:19:04] <tjb1> construction worker on saturdays lol
[18:22:31] <JT-Shop> can you ssh into your plasma?
[18:22:36] <tjb1> no
[18:22:51] <tjb1> i dont have internet at home
[18:23:00] <JT-Shop> take a copy of your config and set up a sim
[18:23:17] <tjb1> I have the linux box up here at school
[18:23:26] <tjb1> I just havent got around to programming it
[18:30:56] <tjb1> Still not sure if I got the correct number for the scale
[18:47:29] <s1dev> a while back someone had a link to a video to a cnc machine center video with a halarious japanese narration anyone still have that?
[18:48:00] <Valen> inst all japanese narration hilarious?
[18:51:56] <JT-Shop> I erased it...
[19:04:40] <Tom_itx> JT-Shop, how's the splitter coming along?
[19:05:34] <JT-Shop> http://imagebin.org/248261
[19:05:45] <JT-Shop> gettin there
[19:05:52] <Tom_itx> looks like andy's lathe post worked for him
[19:06:07] <JT-Shop> kitty break
[19:06:12] <JT-Shop> union rules
[19:06:25] <Tom_itx> heh
[19:06:30] <Tom_itx> do you think you need all those ribs?
[19:06:56] <JT-Shop> no, but I like em
[19:07:15] <Tom_itx> i can see the bottom ones
[19:08:08] <JT-Shop> ?
[19:08:42] <Tom_itx> i doubt you bend the beam
[19:08:59] <JT-Shop> i hope not
[19:08:59] <Tom_itx> not with all those ribs in it
[19:09:15] <Tom_itx> mine was just an I beam with ends welded on
[19:09:44] <JT-Shop> you know how i over do thing
[19:09:45] <Tom_itx> well the wedge was on one end
[19:09:52] <Tom_itx> heh
[19:10:34] <JT-Shop> typin with one finger woody on my lap bondng
[19:10:35] <AR__> why are you making a log splitter
[19:10:56] <JT-Shop> to split fire wood
[19:11:47] <AR__> ok
[19:12:02] <JT-Shop> whew
[19:13:00] <JT-Shop> thought i might have to cut it up for scrap for a min
[19:16:11] <tjb1> What is a good mac text editor for this job?
[19:16:26] <JT-Shop> which job?
[19:16:33] <tjb1> Editing these hal files
[19:16:51] * JT-Shop is going to spyder fest this year
[19:17:17] <JT-Shop> have to ask Andy
[19:17:47] <tjb1> I'm not a fan of spyders....
[19:17:58] <tjb1> Shouldn't be able to get a motorcycle license with one
[19:18:06] <JT-Shop> its an aquired taste
[19:18:44] <tjb1> Well that's just because people can use them to get motorcycle license
[19:18:55] <JT-Shop> not here
[19:20:40] <JT-Shop> say goodnight Gracie
[19:21:08] <L84Supper> alfa spyder?
[19:21:19] <JT-Shop> Can Am
[19:31:33] <AR__> HHAHA
http://www.youtube.com/watch?feature=endscreen&v=nr9Mki_ElXU&NR=1
[19:31:37] <AR__> thats a good one
[19:32:36] <tjb1> say goodnight Gracie?
[19:35:33] <L84Supper> http://www.youtube.com/watch?v=4hVoJjVgoLk I think I just found a source for the new leadscrews for my next table :)
[19:38:52] <AR__> lol i just watched that too
[19:42:01] <L84Supper> http://www.shars.com/ and
http://www.automationtechnologiesinc.com/ (aka Kelling) are ~20 miles apart, if they would share the same building it would save me some driving :)
[19:43:26] <Tecan> AR good1
[19:46:47] <AR__> L84Supper, i got an indicator base from shars and the fucking thing snapped when i tightened the indicator on
[19:47:10] <Tecan> do people actually just clamp stuff in that loose ?
[19:47:11] <AR__> like the part with the holes in that the indicator post goes through
[19:47:20] <AR__> i dunno
[20:11:40] <r00t4rd3d> http://craft-camera.com/EN
[20:12:01] <tjb1> ewww side scrolling website
[20:17:50] <tjb1> JT-Shop: You here?
[20:22:17] <tjb1> pcw_home: ?
[20:26:36] <AR__> i dont like it r00t4rd3d
[20:28:58] <L84Supper> AR__: yeah, some of their stuff is crap, many not so bad
[20:29:17] <tjb1> Can you edit a comp file included in linuxcnc ?
[20:29:28] <tjb1> So I dont have to switch to developer mode and everything
[20:40:42] <ReadError> i ordered 10 clamps today
[20:40:59] <ReadError> come to find out, they have a store on my way home from work ;/
[20:45:32] <Valen> lol
[20:46:35] <tjb1> Valen do you know if you can edit built in comp files without having to add development packages?
[20:47:09] <Valen> why you asking me lol i have nfi
[20:47:20] <tjb1> Well someone has to know!
[20:47:31] <Valen> so ask the channel
[20:47:36] <tjb1> I did
[20:59:23] <R2E4_> -
[21:00:18] <skunkworks> I think you need to have the dev packages
[21:02:31] <skunkworks> tjb1:
http://linuxcnc.org/docs/2.5/html/hal/comp.html#_installing
[21:02:44] <tjb1> To edit one already there?
[21:02:58] <skunkworks> yes - because you need to be able to re-build them
[21:04:28] <skunkworks> http://linuxcnc.org/docs/2.5/html/hal/comp.html#sec:Compiling-realtime-components
[21:05:49] <tjb1> Ah...crap
[21:06:20] <tjb1> and I suppose I can't do this "setp thc.correction-vel (volts_requested - volts)*.001"
[21:07:10] <skunkworks> Isn't there a hal multiplication componant?
[21:08:58] <tjb1> http://linuxcnc.org/docs/html/man/man9/mult2.9.html
[21:32:29] <WalterN> what are some good lasers to use to build a plastic type rapid prototyping machine around?
[21:35:51] <WalterN> assuming I'm asking the right question... I'm not sure what the different process names are for rapid prototyping
[21:40:02] <L84Supper> WalterN: blue ray 405nm laser
[21:41:12] <L84Supper> WalterN: it's called SLA
[21:42:02] <L84Supper> plenty of power and low cost
[21:42:33] <WalterN> SLA is the name (abbreviation) of the rapid prototyping process?
[21:42:50] <L84Supper> http://en.wikipedia.org/wiki/Stereolithography
[21:43:35] <L84Supper> you can also use a DLP projector
[21:48:44] <L84Supper> http://www.youtube.com/watch?v=8ehlWYfdS70
[21:49:21] <R2E4_> When using 5i25 and 7i77 with a bridgeport, I won't need the FMDC not the IFC boards right?
[21:49:40] <WalterN> hmm
[21:51:22] <WalterN> L84Supper: the plastic stuff is expensive though?
[21:51:51] <L84Supper> WalterN: some are lower cost than PLA filament
[21:52:00] <L84Supper> some are higher
[21:52:18] <L84Supper> http://code.google.com/p/lemoncurry/wiki/main
[21:52:37] <L84Supper> WalterN:
http://bucktownpolymers.com/polymer00.html
[21:54:03] <WalterN> haha... color 3D objects
[21:54:07] <WalterN> thats awesome
[21:57:57] <R2E4_> Thats with BOSS 9
[22:00:20] <WalterN> L84Supper: how about powdered plastic?
[22:00:39] <L84Supper> WalterN: with inkjet or laser?
[22:00:43] <WalterN> laser
[22:01:25] <L84Supper> SLS works with plastics and metal powers
[22:02:22] <L84Supper> http://en.wikipedia.org/wiki/Selective_laser_sintering
[22:03:12] <WalterN> L84Supper: I was just planning on making a CNC mill for engraving purposes and planning on spending about $7,000 to make a nice one... never occurred to me to make a rapid prototyping machine.. I'm looking at options to make something nice
[22:03:47] <L84Supper> WalterN: you can use the mill for both
[22:04:23] <L84Supper> 3-axis gantry, just leave enough z-axis movement
[22:04:53] <L84Supper> or mount a laser and galvos on the z-axis
[22:05:24] <WalterN> heh, and use it for laser engraving too
[22:05:29] <L84Supper> or an extrted + nozzle for FDM
[22:05:34] <L84Supper> extruder
[22:05:53] <L84Supper> you can swap lasers
[22:06:21] <L84Supper> UV 405nm for curing photopolymers and IR for sintering or engraving
[22:09:11] <WalterN> CO2 laser... wouldent you use... derp, yeah
[22:09:21] <WalterN> how much would such a laser cost?
[22:10:18] <L84Supper> depends on power output
[22:11:02] <WalterN> what power output is needed?
[22:11:41] <L84Supper> depends on what you want to do
[22:11:55] <WalterN> all the things?
[22:12:01] <WalterN> (lol)
[22:12:12] <L84Supper> take a look at laser cutters and see what they do and how much power they use
[22:12:25] <tjb1> Does lovehappyshopping not sell tubes anymore?
[22:12:36] <L84Supper> blue ray 405nm lasers are ~$10
[22:12:51] <tjb1> http://www.ebay.com/sch/m.html?_odkw=&item=230370586877&pt=LH_DefaultDomain_0&_osacat=0&hash=item35a32830fd&_ssn=love-happyshopping&_trksid=p2046732.m570.l1313&_nkw=laser&_sacat=0&_from=R40
[22:12:56] <WalterN> how much power is necessary to SLS powdered titanium?
[22:13:02] <tjb1> They still sell the power supplies but no more tubes
[22:13:13] <tjb1> I find it odd they sell lasers and tubes and also nail polish and clothing
[22:13:52] <tjb1> http://www.ebay.com/itm/HighQuality-40W-CO2-Sealed-Laser-Engraver-Tube-Water-Cool-70cm-Engraving-Machine-/230926448080?pt=LH_DefaultDomain_0&hash=item35c449f5d0
[22:14:17] <tjb1> 172 for tube and about 165 for the power supply
[22:16:28] <L84Supper> WalterN: it's a matter of physics, it depends on the particle size of the Ti powder and the laser spot size and the speed of sintering
[22:17:06] <WalterN> everything is a matter of physics
[22:17:29] <L84Supper> it's like asking whats a good medicine
[22:17:49] <L84Supper> 1KW for some applications
[22:18:05] <WalterN> in the beam? or input power?
[22:18:21] <L84Supper> output
[22:18:32] <WalterN> so 10kw input
[22:18:33] <WalterN> lol
[22:18:54] <L84Supper> big spot, large particles, high speed
[22:20:09] <AR__> i almost dont want to sell this
[22:20:10] <AR__> http://www.ebay.com/itm/181090544664
[22:21:16] <tjb1> Clever advertising AR__
[22:21:17] <WalterN> is a 100 watt continuous beam usable?
[22:21:24] <L84Supper> 220V 3phase, I have that in my sockets :)
[22:21:25] <AR__> :)
[22:22:19] <L84Supper> WalterN: you'll have to do some research and comparisons for what you'd like to do
[22:22:56] <WalterN> enh
[22:23:11] <WalterN> I know a guy who started making a 100 watt CO2 laser
[22:23:30] <WalterN> I dont think he finished, or if he ever will... might be able to buy it from him

[22:25:12] <WalterN> looks about right

[22:25:22] <WalterN> except he payed a lot less
[22:25:40] <tjb1> What is joyfay?
[22:26:15] <L84Supper> http://www.joyfay.com/us/index.php/about-joyfay-delicate?___store=default
[22:26:29] <tjb1> this like aliebaba or whatever?
[22:27:47] <L84Supper> distributor in Oakland Ca, or at least a phone number there :)
[22:27:48] <WalterN> L84Supper: are most plastic type rapid prototyping machines SLS?
[22:28:07] <tjb1> Most are probably FDM
[22:28:48] <L84Supper> WalterN: all those dinky rickety plastic filament printers are FDF or FFF
[22:29:05] <L84Supper> reprap
[22:29:14] <L84Supper> makerbot etc
[22:29:20] <tjb1> FDF?
[22:29:28] <L84Supper> FDM
[22:29:55] <L84Supper> same thing
[22:30:13] <WalterN> ..?
[22:30:20] <tjb1> fused deposition modeling
[22:30:22] <tjb1> layers of plastic
[22:30:35] <tjb1> filament heated and extruded
[22:31:13] <L84Supper> http://www.automationtechnologiesinc.com/products-page/laser-engraving
[22:31:15] <WalterN> oh
[22:31:25] <WalterN> thats the cheap kind though, I thought
[22:31:28] <L84Supper> 80W tube for $600
[22:31:32] <tjb1> powder is cheaper
[22:31:50] <tjb1> if you are looking at material cost
[22:32:25] <WalterN> I'm looking at all options
[22:32:28] <WalterN> :P
[22:32:40] <AR__> do the powder type :D
[22:33:10] <AR__> a DIY metal FDM machine would be cool
[22:33:18] <tjb1> I'm working on a delta fdm now
[22:33:48] <WalterN> change FDM?
[22:34:15] <WalterN> unless delta means something other than change
[22:34:38] <tjb1> change?
[22:35:08] <L84Supper> http://en.wikipedia.org/wiki/Delta_robot
[22:36:33] <WalterN> oh

[22:47:45] <WalterN> herm
[22:48:14] <WalterN> what is typically used for plastic SLS?
[22:50:05] <toastydeath> sls?
[22:52:51] <WalterN> Selective laser sintering
