#emc | Logs for 2010-02-01

[00:04:55] <terrylm> Somewhere in the docs I seen a parameter or pin that allows jogging before homing. I've looked again but do not find it, does anyone know it?
[00:09:26] <andypugh> I thought you could always jog before homing?
[00:10:38] <andypugh> There is a parameter that lets you run without homing, but I think you should always be able to jog.
[00:11:39] <jimbo> I think that the only way you could not is if it thinks you are on limit. But then it would not power up.
[00:11:47] <andypugh> http://linuxcnc.org/docs/html/config_ini_config.html#sub:%5BTRAJ%5D-section
[00:12:22] <andypugh> There is the over-ride checkbox to fix that situation, anyway.
[00:13:02] <andypugh> Though I do find I have to check the box then jog twice to get off the limit.
[00:16:59] <terrylm> OK, I'm just confused... again. Nothing new :(
[00:19:40] <terrylm> BTW, I got the step signal to the drive amps working (last night it was not). I removed all lines from the hal file that had parport and reset in the same 'word' and the problem vanished.
[00:27:22] <andypugh> You might want to put the reset back, and add an "invert". Possibly. It sounds like the pulse didn't suit your drives, but they might be happy with a very short negative pulse rather than a short positive one.
[00:27:25] <andypugh> http://linuxcnc.org/docs/html/hal_drivers.html#r1_1_2
[00:27:41] <terrylm> Back to the jogging problem. The axis moves if I home the axis, so it can move. But no jog. I checked axis.2.jog-enable and it is false. Any idea why?
[00:28:36] <terrylm> No, there was no pulse, I check with a hard O-scope.
[00:29:14] <terrylm> The steps work great now. Home moves great.
[00:30:05] <andypugh> OK. You might be able to double the step rate with the reset function, and it is plausible that the pulses were too short for your scope.
[00:30:30] <andypugh> But there is no point if you don't need a higher step rate (and you probably don't)
[00:30:31] <terrylm> 15MHz scope.
[00:31:10] <terrylm> nop
[00:32:00] <terrylm> I must be missing a signal connection in the hal file to enable jogging. Any ideas?
[00:32:01] <andypugh> 66nS pulses @ 15MHz by my calculation. I doubt that they are that short.
[00:32:31] <andypugh> I just checked and the jog-enable pins stay false even when jogging does happen
[00:32:41] <terrylm> oh
[00:33:11] <andypugh> It's an input to allow jogging from a pendant, I think
[00:33:37] <andypugh> You say you can jog after homing?
[00:33:43] <andypugh> Or never?
[00:35:01] <terrylm> Not sure, need to adjust the proximity switch, but need to move the carriage back to do it, and no jog.
[00:35:39] <andypugh> I left the handles on :-)
[00:35:39] <terrylm> I've never had this machine working. Just got the axises to move today.
[00:36:18] <terrylm> It has yet to ever be homed.
[00:37:28] <andypugh> Is it actually on the limit switch? You will see an arrow to the right of the position display in Axis if it is. (but the error box is a giveaway too)
[00:38:00] <terrylm> I can move the carriage out of the way by flipping the home direction... . There are no limit switches.
[00:38:32] <andypugh> So, it will home but not jog?
[00:38:42] <terrylm> correct.
[00:38:48] <andypugh> jog speed set to zero?
[00:39:00] <terrylm> 10 in./min.
[00:39:08] <Valen> feed override?
[00:39:12] <Valen> max speed?
[00:39:15] <terrylm> oh, jog speed, hang on...
[00:39:40] <terrylm> 9in/min
[00:39:51] <andypugh> Do the display numbers change?
[00:39:53] <terrylm> feed override 100%
[00:39:57] <terrylm> no
[00:40:41] <andypugh> How are you jogging? cursor-keys or on-screen buttons?
[00:41:12] <terrylm> I'm not, just changing the homing direction back and forth...
[00:41:28] <andypugh> OK, so how are you failing to jog :-)
[00:41:29] <terrylm> Oh, on screen
[00:41:56] <andypugh> Standard Axis GUI?
[00:42:22] <andypugh> Not a pyVCP custom GUI with non-wired buttons or anything like that?
[00:42:44] <terrylm> yes, no
[00:43:17] <andypugh> I am baffled then.
[00:43:20] <kristianpaul> there is special SVG to be used with HeeksCad?
[00:43:22] <terrylm> I just check, the side arrow key on the keyboard do nothing.
[00:44:00] <terrylm> What keyboard keys for jogging? side arrows?
[00:45:01] <andypugh> Yes, cursor keys. or you can press + and -
[00:45:26] <Valen> set it to allow run without homing
[00:45:46] <Valen> I'm not sure you can jog if not homed
[00:46:45] <andypugh> You definitely can jog if not homed.
[00:47:14] <Valen> Just a thought, its pretty easy to try
[00:47:22] <terrylm> Do you recall how that is done?
[00:47:31] <andypugh> But in the interim, set your home velocity to 0 if you have no home switches, then you can home at the current position from the GUI
[00:47:43] <terrylm> what?
[00:48:04] <terrylm> OH
[00:48:29] <andypugh> In the ini file, set home velocity to 0. Then the axes just home where they are when you press the butin.
[00:48:45] <andypugh> err, button.
[00:56:17] <andypugh> I have just had a moment of doubt about whether I am right about setting home velocity to zero.
[00:57:49] <terrylm> It does move some, then stops and is homed.
[00:58:10] <andypugh> That's odd.
[00:58:11] <terrylm> Both axises are not home as such, but still no jog.
[00:58:15] <andypugh> Does it jog?
[00:58:21] <terrylm> no
[00:59:00] <andypugh> Go to MDI and see what G0 X1 Y1 (or some positions close to the current ones) does.
[00:59:22] <andypugh> (MDI is the other tab on the left, F5 gets you there too)
[00:59:43] <andypugh> Where did the config files come from?
[01:00:01] <terrylm> Oh, the movement was when it when to the home pos. after setting home offset.
[01:00:20] <terrylm> stepgen, then I massively changed it.
[01:00:56] <terrylm> let me see if MDI works...
[01:03:19] <terrylm> humm ... MDI commands do nothing, no change in displayed position.
[01:03:55] <terrylm> There must be some sort of enable that I'm missing?
[01:03:58] <andypugh> That's very peculiar. No error messages?
[01:04:12] <terrylm> no
[01:04:31] <andypugh> pastebin the HAL file?
[01:04:53] <andypugh> (www.pastebin.ca or similar)
[01:05:12] <terrylm> But I have been messing with the ladder to get my panel buttons working power/estop, maybe I messed it up.
[01:05:19] <terrylm> OK
[01:07:12] <terrylm> one moment...
[01:08:35] <skunkworks> http://www.electronicsam.com/images/KandT/conversion/xaxis/xaxisshaft.JPG
[01:08:54] <skunkworks> http://www.electronicsam.com/images/KandT/conversion/xaxis/xaxisshaft1.JPG
[01:09:18] <skunkworks> http://www.electronicsam.com/images/KandT/conversion/xaxis/xaxisshaft2.JPG
[01:10:05] <andypugh> You made the splines yourself?
[01:11:15] <ries> can I test in gcode if the X axis is smaller then 0? For example O202 if [X lt 0]
[01:11:21] <skunkworks> no - that was from the original workings.. we are using it as an easy way to couple the power. they splines are awesome - no backlash.
[01:12:06] <skunkworks> *the splines
[01:12:24] <andypugh> ries: Not directly.
[01:12:49] <ries> andypugh: what would be the solution? track it myself or...
[01:12:54] <andypugh> ries: But you can do it with G92 X0 then G92.1.
[01:13:19] <ries> let me look that up.. never used G92...
[01:13:21] <andypugh> Then read the value from #<errr, let me look>
[01:13:28] <terrylm> ok http://pastebin.ca/1773860
[01:15:00] <ries> andypugh: basicly I want to skip some Gcode as soon as I am < 0, this to save some cutting time in air...
[01:15:35] <andypugh> ries: Sorry. You want G92 X0, then read the value in #5211 then clear it all with G92.1
[01:16:12] <andypugh> But that is only sensible if you don't know where you are. If you are using a variable to store the target-X, use that.
[01:17:32] <ries> basicly I generate a pattern for my dovetails, and I want to solve some items using relative positioning so I can repeat a sub for each section
[01:18:03] <ries> so, within the subs I don't know where I am absolutely (I do know, but I would need to calculate that... and trying to avoid)
[01:20:16] <andypugh> I use the G92 trick so I can jog to a start point, then machine from there to finished size.
[01:20:45] <andypugh> terrylm: It looks fine, but try commenting out the very last line, feed-hold?
[01:20:46] <ries> going to check that out... thanks for the pointer
[01:21:34] <andypugh> G92 X0 stores the offset needed to make the current X=0, which just so happens to be the current X (or Y, or Z or whatever)
[01:26:03] <terrylm> ok
[01:27:14] <andypugh> I need to sleep now. You could try looking in machine -> show hal config and checking that all the stepgen and axis velocities etc are picking up sane values from the ini file.
[01:27:26] <terrylm> That WAS it! Thank you very much.
[01:27:55] <andypugh> Great. :-)
[01:28:25] <andypugh> I guess that pin is unconnected and pulled-up?
[01:29:04] <andypugh> OK, night all.
[01:30:06] <terrylm> I needed to invert that input.
[01:44:57] <terrylm> I'm happy, just homed the Z axis for real and can jog. People here are so great, if it was not for you folks I would still be banging my head over an imput pin that needed to be not-ed.
[02:09:55] <terrylm> Spindle question, at low speeds (<700 RPM) the speed varies up and down, gets worse the slower I try to run it.
[02:10:46] <terrylm> There is not PID, should there be? This is orig. from stepgen.
[02:43:47] <terrylm> Anyone actually here?
[03:06:22] <ds3> wheeeeee finally got all the foundation stuff setup and at the point of trying to configure EMC for the machine!!
[03:07:05] <bevins> ds3: what kind of machine?
[03:08:44] <ds3> bevins: a basic 2 axis open loop stepper machine
[03:09:19] <ds3> hmmm stepconf seems to be what I want... now to find out if my ancient version of EMC has it
[03:09:23] <bevins> x and y. no up and down?
[03:10:18] <ds3> *nod* just X and Y
[03:11:24] <bevins> what are you doing that you don't need Z?
[03:12:34] <ds3> engraving
[03:13:20] <bevins> wow. I use Z all the time whilst engraving
[03:14:34] <ds3> the engraving head is a laser
[03:14:48] <ds3> so it is a binary on/off.. no autofocus so no z
[03:14:49] <bevins> Ah! cool!
[03:15:20] <bevins> how big is the laser? Can you cut with it?
[03:16:08] <ds3> it is listed as a 40W but it is an import unit so, I donno is probally more accurate
[03:16:56] <ds3> it may cut but won't know til I get it working; I am pretty much ignoring the specs and figuring things out bit by bit
[03:17:47] <bevins> I wonder if I can stick a laser on my cnc-router. How much are they?
[03:18:07] <ds3> the tube is around $400
[03:18:36] <ds3> mine is used and through a convoluted arragnement so there isn't an accurate $ figure for it
[03:22:07] <bevins> Will it engrave aluminum?
[03:22:22] <ds3> only anodized
[03:23:00] <bevins> because of the melting issues?
[03:23:07] <ds3> no, not enough power
[03:23:25] <bevins> I see. thats a cool project
[03:23:58] <ds3> assuming it works
[03:25:10] <bevins> the laser part or the cnc part? lol
[03:26:12] <ds3> sigh... strike 1
[03:26:42] <ds3> I so hate ubuntu
[03:26:45] <bevins> emc is not for the faint of heart
[03:27:23] <bevins> I went back to mach3 with a beefier computer cause I couldn't gt it to do what I wanted
[03:27:33] <ds3> it isn't emc, it is @#$@#$@#%$$@# ubuntu
[03:27:43] <bevins> but emc is cool.
[03:27:49] <ds3> the version I have setup is too old so it doesn't have stepconf
[03:28:02] <ds3> but the PoS ubuntu is going to complicate things
[03:28:13] <terrylm> Hi. I've got a hal file that was made with stepconf and then modified by me. Stepconf did not include PID on the spindle, should it have? it wobbles in speed at low speeds.
[03:29:20] <bevins> if it wobbles at low speed it will wobble at high speed
[03:29:48] <bevins> you just wont see it...lol
[03:30:04] <cradek> the normal configuration for spindle speed is open loop. tell us more about your setup for a better answer
[03:30:22] <terrylm> Yes, it is only tiny at high speeds.
[03:30:38] <cradek> are you talking about an ac motor on a vfd, or something else?
[03:30:52] <ds3> what is the easiest way to upgrade a EMC2 setup that is not connected to the network?
[03:31:03] <terrylm> Oh, ya, I did have to add the encoder line.
[03:31:12] <ds3> setup was built by one of the Live cds from a long time ago
[03:31:21] <cradek> ds3: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.3
[03:31:32] <bevins> download a new live cd. it has it and really fast
[03:31:47] <terrylm> It is a DC motor, brushed, with a PWM drive amp.
[03:31:52] <cradek> getting the latest cd is a good idea if you have that option
[03:31:57] <terrylm> and a relay to reverse.
[03:32:09] <cradek> terrylm: what's generating the pwm?
[03:32:28] <cradek> I mean how does it take a speed command?
[03:32:35] <terrylm> let me check...
[03:33:10] <ds3> I am trying not to blow another week moving the machines around so it has network access to run a livecd to reinstall it
[03:33:55] <bevins> Download it and burn it on a cd then boot the machine off the cd. why would you have to move the machine>?
[03:34:31] <ds3> I want to install that to the HD
[03:34:48] <bevins> you can install it to the HD from a live cd
[03:35:01] <ds3> IIRC, that wants a live internet connection
[03:35:15] <bevins> no it doesn't
[03:35:31] <bevins> I just did it twice last night with no internet connection
[03:35:46] <terrylm> motion.spindle.out => pwmgen.0.value, and from pwmgen out the parport
[03:35:51] <ds3> hmmmm and does the latest ubuntu run on a K6-2?
[03:36:01] <ds3> ;)
[03:36:35] <cradek> terrylm: are you using pwm or pdm mode? you've got some serious limitations with parport pwm/pdm.
[03:36:48] <ds3> if all it needs is those 3 debs, I much rather go that route
[03:36:57] <terrylm> pwm
[03:36:58] <bevins> it does on 7 so it should
[03:37:06] <ds3> avoids having to fix the ubuntu-isms
[03:37:16] <terrylm> 500hz
[03:37:32] <cradek> terrylm: I'm guessing you don't need pid, you need a better signal
[03:37:51] <bevins> k6-2 450Mhz runs with ubuntu 7
[03:37:52] <cradek> what's your base period?
[03:37:53] <ds3> cradek: is there another place to get the pango updates? the links on that page doesn't work
[03:38:04] <cradek> ds3: sorry, I don't know
[03:38:04] <terrylm> 20ns
[03:38:31] <ds3> again, I say... ubuntu... grrrrrrrr
[03:38:39] <ds3> need good old slackware
[03:38:54] <cradek> ds3: so build and install it on some other system.
[03:39:43] <cradek> terrylm: does your amp have enough input filtering that 500Hz pwm is adequate?
[03:40:07] <bevins> ds3, get an iso and rape it for the files
[03:41:09] <bevins> like from http://releases.ubuntu.com/kubuntu/hardy/
[03:41:15] <terrylm> errr 20000ns
[03:41:37] <ds3> cradek: How hard is it to write a config by hand?
[03:42:03] <terrylm> yes, the amp docs recomended 500Hz as I recall.
[03:42:24] <terrylm> I can try faster.
[03:42:34] <cradek> you'll get fewer steps if so
[03:42:39] <cradek> maybe you should try pdm
[03:43:27] <ds3> downloading new ISO... guess this is not going to get working tonight
[03:44:05] <terrylm> Well, the amps are really 0V to 10V opperated, but the docs say a 500Hz PWM can also be used. 500 may have been the min., don't remember.
[03:44:09] <bevins> have faith
[03:44:51] <cradek> terrylm: spindle doesn't have to respond fast - you could try adding about a 1s time constant RC filter
[03:51:22] <cradek> terrylm: a physical filter, not software. there's nothing you can do in software to get a cleaner analog signal out of a digital output
[05:35:16] <Valen> if its 0-10v I'd say its a minimum
[05:35:56] <Valen> I would suggest minimum 1khz or so,
[05:36:37] <Jymmm> I think I'm gonna build one http://www.digitalhome.ca/ota/superantenna/hovermanpvc.jpg
[05:37:11] <Valen> uhm why?
[05:37:24] <Jymmm> ooops wrong channel - it's an antenna
[05:39:24] <LawrenceG> Jymmm, 2mtrs?
[05:39:36] <Jymmm> LawrenceG: OTA
[05:39:44] <Jymmm> UHF
[05:39:52] <LawrenceG> website?
[05:40:01] <Jymmm> LawrenceG: http://www.digitalhome.ca/ota/superantenna/design.htm
[05:40:17] <Jymmm> based on a design patented in the 60's
[05:42:24] <Jymmm> LawrenceG: I think I want to try and simply the fabrication a bit
[05:42:45] <Jymmm> LawrenceG: I hae a butt load of pvc connectors around here
[05:43:36] <Jymmm> * Jymmm pokes LawrenceG
[05:46:12] <LawrenceG> ouch
[05:46:56] <Jymmm> pay attention!
[05:46:58] <Jymmm> lol
[05:47:23] <Jymmm> it's roughly 60" tall
[05:47:50] <Jymmm> would like it to look less ghetto though
[05:48:31] <LawrenceG> I want to turn a 1/2" pipe cap on the lathe so that it is spherical (ie half round end).... I dont have a ball turner tooling, but I do have cnc... how good are lathe tool offsets?
[05:48:38] <Jymmm> smaller pvc pipes might help, maybe fiberglass rods.
[05:51:14] <Jymmm> I've never seen a pvc pipe cap thick enugh to make into a dome
[05:51:29] <LawrenceG> this is black iron pipe
[05:51:35] <Jymmm> ah
[05:52:29] <LawrenceG> it may or may not have enough meat to get a full hemisphere.... I bought a couple of caps :}
[05:52:44] <Jymmm> why a dome?
[05:53:02] <Jymmm> go for nice shiny point
[05:53:48] <LawrenceG> http://www.youtube.com/watch?v=8BUm2BK3-qw is sort of the idea
[05:54:20] <LawrenceG> not using a flare cap
[06:04:00] <Jymmm> LawrenceG: Ok, wth is that for?
[06:05:16] <Jymmm> LawrenceG: Also did you see this:
[06:05:17] <Jymmm> I did almost the same thing but I discovered that if you cut a V shaped groove on the tip of the nozzle with a dremel cutoff disk about 3/16 of an inch wide on top and taper it to 1/16 of an inch wide directly centered on the 1/64 air hole and cut it about 1/16 deep it channels the oil directly over the air jet hole and it uses less oil, gets a cleaner burn, and alot less side splatter from oil not getting fully atomized.
[06:05:53] <Jymmm> I'm sure that there's more than enough meat on a pipe cap to do that
[06:11:58] <Jymmm> LawrenceG: steam http://www.youtube.com/watch?v=mfgIfOcWhas
[06:13:00] <Jymmm> LawrenceG: If youhad a coil of tubing with a one-way check valve, the heat from the burner might be enough to introduce pressure thru the jet I'd think, once it got hot enough that is.
[06:13:46] <Jymmm> maybe get it warm with the hand torch just to get it started
[06:15:14] <MrSunshine> babington burners looks like a real fire hazard =)
[06:15:44] <LawrenceG> yup... flaming oil...
[06:16:18] <MrSunshine> as it then drips down and i guess needs to be collected? :)
[06:16:19] <Jymmm> http://www.youtube.com/watch?v=HK5UtmObxyw&NR=1
[06:16:29] <LawrenceG> the nice thing about them is you can use dirty oil... the orifice is only used to pass compressed air
[06:16:46] <MrSunshine> LawrenceG, mm :)
[06:17:33] <Jymmm> LawrenceG: But how well does it burn it?
[06:17:45] <MrSunshine> or does it use surface tension to make it never drip when its finley tuned? :)
[06:19:16] <MrSunshine> and i guess with additional air it should be able to reach blue flame :)
[06:19:32] <MrSunshine> <--- hobbyist blacksmith and need cheap ways to heat metal :P
[06:19:43] <LawrenceG> you need to account for drips.... that guys design doesnt really cover that part of the problem.. real babington burners use a full sphere to get a nice consistant thickness of oil past the orifice and literally have it running on the sphere
[06:19:44] <Jymmm> MrSunshine: eat beasns
[06:19:53] <MrSunshine> beasns ? :P
[06:20:02] <Jymmm> MrSunshine: the REAL natural gas
[06:20:12] <MrSunshine> ahh :P
[06:20:14] <MrSunshine> beans :P
[06:20:35] <LawrenceG> there are several of these designs used to heat aluminium melting furnaces
[06:20:58] <MrSunshine> well its oil, should be able to melt almost everything as long as you pour enough of it on :P
[06:21:05] <LawrenceG> usually by adding forced air blower to improve combustion
[06:21:20] <MrSunshine> atleast ordenary oil burners has been used for meling cast iron :)
[06:23:27] <LawrenceG> yes... a lot of the furnace burners just blow oil drops into the furnace and as long as it has been preheated with propane, that works ok.... using the babington idea to inject oild eliminates the propane preheat stage
[06:23:38] <Jymmm> LawrenceG: so whatcha doin with this burner?
[06:24:23] <LawrenceG> 2 uses.... heat water for heating the house and also for a foundry furnace
[06:24:47] <Jymmm> LawrenceG: how clean does it burn?
[06:24:52] <MrSunshine> LawrenceG, and that is nice :) tho i have an oil burner like those in the "furnaces?" in a house for heating the house, those has been successfully used for meling loads of metal :)
[06:25:34] <MrSunshine> but still, waste oil is nice :P
[06:25:42] <MrSunshine> as i need commercial oil for that one :)
[06:25:58] <Jymmm> used fry oil
[06:26:21] <LawrenceG> should burn totally smokeless if proper atomization and air is used.... I want to use fry oil... the spills are easier to deal with
[06:27:39] <LawrenceG> the EPA are kind of like the IRS.... the less you see of them the better (substitute Canadian equiv's)
[06:28:29] <Jymmm> heh, run the smoke thru charcoal filter =)
[06:28:43] <MrSunshine> i need to build a "smoker" ...
[06:28:50] <MrSunshine> got a heart from a moose i need to smoke :)
[06:28:56] <MrSunshine> ok that just sounds wrong :P
[06:29:02] <Jymmm> MrSunshine: here ya go, a smoker http://freeheatmachine.com/
[06:29:51] <L84Supper> smoked moose heart!
[06:30:55] <LawrenceG> Jymmm, thats the idea external furnace (portable) that burns fry oil..... the house fire insurance is so much easier todeal with if the garden shed burns down.
[06:31:39] <Jymmm> lol, and cheaper too
[06:35:35] <LawrenceG> http://imagebin.ca/view/mOAg_3.html this is a nice ball turning jig for a lathe
[06:37:01] <LawrenceG> http://imagebin.ca/view/VX9dnQ.html another version
[06:37:39] <Jymmm> LawrenceG: Have you consided GeoThermal?
[06:37:59] <LawrenceG> yes... I want cheap
[06:38:16] <Jymmm> LawrenceG: No wood to load/burn EVER
[06:38:26] <Jymmm> LawrenceG: and works to COOL too
[06:38:55] <LawrenceG> thats why I like fry oil..... collect it a couple of times a year and no chopping required
[06:39:19] <Jymmm> and the summer?
[06:39:46] <LawrenceG> I already have a heat pump/ac
[06:40:04] <MrSunshine> * MrSunshine has ground heat, but doesnt put out enough of heat to heat the house so it keeps putting in the "extra" ... 6kw electrical heater
[06:40:14] <MrSunshine> its enough down to like -10 deg C
[06:40:24] <MrSunshine> but then it starts costing me loads of money :P
[06:40:39] <MrSunshine> lucky i still have the wood burning ability in the house :P
[06:41:11] <LawrenceG> this has been a great winter so far.. Jan has been +5C to +10C most of the time... the air heat pump is happy
[06:41:19] <Jymmm> If you think about it, solar SHOULD be enough to cover the AC usage in the summertime you would think at least
[06:41:43] <Jymmm> LawrenceG: what does a "heat pump" do?
[06:42:04] <LawrenceG> I live too far north for solar... not enough sunny days here unless the panels are really cheap
[06:42:10] <MrSunshine> we had -35 deg C where i live :P
[06:42:12] <MrSunshine> in january
[06:43:01] <LawrenceG> a heat pump moves heat from one place to another (your fridge is an example) It has a hot and a cold side... typically 25C difference
[06:43:13] <MrSunshine> i was on a trip to alaska, there we had like -25 to -35 deg C, then when i was going home i thought "oh glory day finaly some hotter weather" ... well ... -32 deg C the first night i got home :P
[06:43:42] <Jymmm> LawrenceG: , ok so how does that work to cool a house in the summer?
[06:44:33] <LawrenceG> I live within a hundred feet of the pacific ocean, but getting across the beach to access the sea water makes a very clean heat pump solution just about impossible
[06:45:08] <Jymmm> dig deeper? lol
[06:45:09] <LawrenceG> it pumps heat out of the house and tries to make the outside hotter
[06:45:27] <Jymmm> eh, ok.
[06:45:54] <Jymmm> sounds like a fan to me
[06:46:10] <Jymmm> *shrug*
[06:46:43] <LawrenceG> sort of... a fan that delivers air that is 25C cooler on one side than the other
[06:47:19] <Jymmm> I'll research it later =)
[06:48:31] <Jymmm> First, I think I want to try the uhf antenna
[06:48:57] <Jymmm> I'll build a single and see how it goes.
[06:50:07] <LawrenceG> cool.... I am off to bed.... gnite
[06:52:03] <L84Supper> anyone here ever tried BRL-CAD? http://brlcad.org/
[06:56:03] <MrSunshine> uhf antenna ?
[06:56:31] <MrSunshine> hdtv antenna? :)
[06:58:21] <Jymmm> same diff
[07:01:32] <renesis> guys my emc is starting up with an error like '$NMLFILE: ambiguous redirect' at the end of the debug file
[07:01:40] <renesis> why is it broken it was working this morning =(
[07:01:56] <Jymmm> http://www.youtube.com/watch?v=5erjj6aS5Ws&NR=1&feature=fvwp
[07:03:21] <MrSunshine> http://existenz.se/out.php?id=20777 cool =)
[07:04:46] <renesis> retinal burn in, shrug
[07:05:16] <renesis> you never see spots when you close your eyes after seeing some lights?
[07:07:01] <MrSunshine> huh ? :) still its cool that the colors come from the houses as long as you look at the spot
[07:07:08] <MrSunshine> but move your eyes and they turn black and gray :)
[07:12:44] <Jymmm> Alright, new toy to build... http://www.youtube.com/watch?v=2HcYfTkVFQ8&NR=1
[10:27:27] <piasdom> g'morning all
[10:56:09] <alex_joni> hi
[11:11:59] <Jymmm> alex_joni: wake up and go back to sleep
[11:14:44] <alex_joni> sounds like a very good idea
[13:04:18] <MOGLI> hello can anyone help me with MULTI START THREADING?? i want 3 start threading.. G76 is starting at index pulse only...
[13:05:43] <MOGLI> hello anybody here.....
[13:06:58] <celeron55> someone will probably answer, just wait
[13:07:47] <celeron55> it's monday 8:07am in New York at the moment, for example
[13:08:47] <MOGLI> thanks celeron55
[13:09:40] <jthornton> MOGLI: I "think" you just have to offset your start point in Z by the pitch difference between each start
[13:11:26] <MOGLI> will it work?? let me try it....
[13:19:53] <alex_joni> MOGLI: programm 3 runs
[13:20:03] <alex_joni> with the 3 offsets (0, x, 2*x)
[13:20:07] <alex_joni> err.. z ;)
[13:27:34] <MOGLI> alex_joni for 3 start entry threading?? Threading
[13:28:11] <MOGLI> same G76 but starting point is different.. for example pitch is 12 than first Z is 0 second 4 and third 8 .. right???
[13:29:38] <alex_joni> right
[13:30:18] <MOGLI> thanks alex_joni..
[13:33:40] <alex_joni> try it out first .)
[13:45:50] <MOGLI> hey alext it didnt workout...
[13:47:20] <MOGLI> helllo here is the GCODE i used http://pastebin.ca/1774328
[13:47:27] <MOGLI> its 4 line code only...
[13:48:43] <MOGLI> N1 G0 X-1 Z0 N2 G76 Z-30 P6 I1.25 R1 J0.05 K0.75 Q30 H0 N3 G0 X-1 Z3.0 N4 G76 Z-30 P6 I1.25 R1 J0.05 K0.75 Q30 H0
[13:49:08] <MOGLI> hello jthornton , alex_joni u there???
[13:54:06] <MOGLI> helllo anybody here??
[13:55:40] <celeron55> so what did the code do?
[13:56:46] <archivist> MOGLI, you may need to wait much longer for replies in IRC
[13:58:29] <MOGLI> same entry threading... but increses width..
[13:58:44] <MOGLI> ok archivist... m waiting..
[13:59:27] <jthornton> if it increased the width then perhaps your offset is too big or too small
[13:59:37] <archivist> I would run it then I would know
[14:00:28] <jthornton> * jthornton heads out to work
[14:00:57] <MOGLI> can you correct the code jthornton??
[14:01:37] <Guest418> Guest418 is now known as skunkworks_
[14:01:38] <jthornton> I don't have any way to test it until I finish my lathe conversion, sorry
[14:11:02] <alex_joni> MOGLI: http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg03866.html
[14:11:23] <frallzor> chinese steel, not all too bad
[14:15:05] <MOGLI> thanks alex_joni looking at it..
[14:37:49] <awallin> anyone been using boost-python to call C/C++ programs from python?
[14:38:14] <awallin> I'm trying a multi-threading test (witn OpenMP), but when called from python it only seems to use one cpu core?
[14:39:48] <skunkworks_> http://www.youtube.com/watch?v=2fUcCoj7APQ
[14:41:30] <numen> does emc2 run on an amd x2 with the 2 cpu cores?
[14:44:17] <skunkworks_> that lath only has about .020 taper in 10 inches... (we really need to fix that at some point)
[14:44:19] <skunkworks_> lathe
[14:49:43] <Jymmm> skunkworks_: didn't that have that machine back like 20 years ago?
[14:49:47] <Jymmm> 200
[14:49:59] <Jymmm> water/slave powered
[14:51:06] <Jymmm> Now, THIS is a great use for a lathe http://www.youtube.com/watch?v=EKL6elkbFy0&NR=1
[14:55:27] <skunkworks_> we have not clue how old it is.. it is old!
[14:56:32] <skunkworks_> started out using flat belts as you can see.
[14:57:58] <skunkworks_> you have to keep the bearings oiled or the over-temp trips on the motor :)
[14:58:40] <Jymmm> nd by oiled, you mean apply whale blubber to the moving parts
[14:59:00] <WalterN> haha
[14:59:06] <WalterN> cysco
[14:59:19] <WalterN> or soap as last resort
[14:59:28] <Jymmm> renderer pork fat
[14:59:36] <Jymmm> they had that in the 1800's
[14:59:46] <WalterN> awesome
[14:59:54] <WalterN> well
[14:59:57] <WalterN> not so much
[15:00:00] <WalterN> for them
[15:00:03] <WalterN> but.. yeah
[15:43:19] <anonimasu> w

[16:51:53] <skunkworks_> JanVanGilsen: how is the puma coming
[16:51:54] <skunkworks_> ?
[16:56:33] <JanVanGilsen> Well I got all joints working :)
[16:58:47] <JanVanGilsen> I only have to adjust the home position of 1 joint to get the kinematics running (so it can run simultaneously with the vismach puma)
[16:59:45] <JanVanGilsen> All joints home with the pot-meter and index resulting in a fast homing procedure
[17:00:55] <JanVanGilsen> I also hooked up a wireless game-pad as remote pendant
[17:01:52] <JanVanGilsen> I'mm hoping to get the kinematics running in 2 weeks (I'm only able to work on it during the weekend)
[17:02:25] <skunkworks_> very cool!
[17:12:05] <danimal_garage> skunkworks: my antique lathe: http://img.photobucket.com/albums/v20/danielwilcox/DSCN0015.jpg
[17:12:18] <danimal_garage> probably circa 1910-ish
[17:14:33] <skunkworks_> neat - bit better shape than ours ;)
[17:14:54] <danimal_garage> i restored it
[17:15:05] <tarzan> south bend?
[17:15:20] <danimal_garage> rockford
[17:15:54] <archivist> * archivist has a Southbend
[17:16:04] <archivist> well worn
[17:16:30] <danimal_garage> mine is pretty worn, but it can still turn a pretty straight shaft
[17:16:39] <danimal_garage> not much taper
[17:17:22] <tarzan> strange oilers
[17:17:45] <danimal_garage> yea, just selanoids on there so it doesnt oil when it's not running
[17:18:14] <archivist> I made a shaft for a steam valve on mine, was fun adjusting dia as it turned
[17:28:19] <danimal_garage> sounds fun
[17:28:40] <danimal_garage> i really want an id/od grinder
[17:28:58] <danimal_garage> and a blanchard
[17:36:49] <danimal_garage> and 2 goats
[17:37:18] <bill2or3> and coffee.
[17:39:34] <danimal_garage> never had a cup in my life
[17:49:30] <ries> danimal_garage: you are missing something....
[17:49:59] <danimal_garage> the goats?
[17:54:42] <danimal_garage> please dont say coffee, the smell is gross
[18:09:11] <celeron55> i too haven't had a cup of coffee in my life
[18:09:53] <micges> happy you
[18:11:46] <archivist> * archivist drinks coffee and wafts the whiff across the sea
[18:20:08] <danimal_garage> * danimal_garage rips one and wafts the wiff across the sea
[18:21:41] <archivist> * archivist complains about the onions
[18:22:20] <danimal_garage> * danimal_garage says archivist is lucky it was me and not the dog
[18:24:24] <danimal_garage> * danimal_garage realizes i should have my lathe in high gear.
[18:24:40] <danimal_garage> no wonder it's been taking so long to spin up
[18:25:49] <JanVanGilsen> skunkworks_: Did the puma drawings/circuit diagrams I've sent you have any use?
[19:23:12] <danimal_garage> having a cnc lathe sure makes life easier
[19:24:44] <danimal_garage> hey i'm having issues with my spindles on both the mill and lathe... how do i get the 7i33 to put out +10v instead of -10v when going in reverse?
[19:26:01] <danimal_garage> never thought i'd need reverse on the lathe, but the first job i did i needed it lol
[19:26:30] <JT-Work> I hope you figure it out before I get that far :)
[19:26:53] <danimal_garage> haha you dont need to figure it out
[19:27:01] <danimal_garage> you probably need -10v
[19:27:16] <danimal_garage> i have a regular 3 phase motor, not a servo
[19:27:22] <JT-Work> no mine is like yours 0-10v and a direction pin
[19:27:41] <JT-Work> except it is a servo
[19:28:20] <danimal_garage> ohh
[19:28:38] <danimal_garage> ok i will let you know
[19:28:43] <danimal_garage> how's it coming?
[19:30:29] <JT-Work> I got more done yesterday on the wiring then my playmates (that's what my wife calls them) wanted me to join them to play with guns :)
[19:30:46] <danimal_garage> cool
[19:30:58] <danimal_garage> cant wait to see her run
[19:31:07] <danimal_garage> what's your max ipm?
[19:31:14] <JT-Work> a few more connections in the back and the phase converter motor can go back in and off to the other side to install the computer
[19:31:44] <JT-Work> I'm not sure but it won't matter much there ain't much for X and Z
[19:32:00] <danimal_garage> manual doesnt say?
[19:32:14] <danimal_garage> true, at 200ipm, it seems like plenty on mine
[19:32:32] <JT-Work> somewhere I saw it but don't recall atm
[19:33:37] <danimal_garage> i'm making these filter caps for a filtration unit that'll filter out viruses and whatnot
[19:33:44] <danimal_garage> they're going to haiti
[19:34:00] <danimal_garage> kind of a pain in the ass part
[19:34:18] <JT-Work> what do the caps fit on?
[19:34:34] <danimal_garage> has a tube inside a cup, so i gotta turn the od of the inner tube with a boring bar from the back side, spindle in reverse
[19:34:39] <danimal_garage> not sure
[19:34:54] <danimal_garage> it gets filled with epoxy and fivers that the water goes through
[19:34:59] <danimal_garage> filters*
[19:36:08] <danimal_garage> but since my spindle wont go in reverse via emc, i gotta use the keypad on my vfd to change directions
[19:36:57] <JT-Work> your vfd has a direction pin?
[19:37:02] <danimal_garage> yes
[19:37:30] <danimal_garage> i have another vfd that might work better, that one can run on + or - 10v
[19:37:59] <JT-Work> my first guess is to filter your speed command through abs
[19:38:16] <JT-Work> to get an absolute value no matter the input
[19:38:30] <danimal_garage> ah ok
[19:38:37] <danimal_garage> i'll try that out
[19:38:57] <Eric_K> then filter it through sign
[19:39:01] <danimal_garage> i'm kinda screwed right now anyways since i'm out of output pins
[19:39:30] <danimal_garage> you might need 2 7i33's, fyi
[19:39:55] <JT-Work> for the direction pin?
[19:40:26] <danimal_garage> i dunno, i just ran out
[19:40:41] <danimal_garage> oh.. yes, i need another for the direction pins
[19:41:00] <robh_> to make a +10 always spindle out for mesa, just make the spindle from EMC and ABS value so its allways posative
[19:41:17] <danimal_garage> thanks robh_
[19:41:18] <JT-Work> hi robh_
[19:41:23] <robh_> Hay john
[19:41:34] <robh_> then if u wanna reverse it just invert the dac chanel
[19:41:56] <robh_> if it outputs -10 not +10 that is once its a Absolute value
[19:44:41] <robh_> JT-Work, im working on EMC Lathe post now hope ur ready to test it soon ;)
[19:44:53] <JT-Work> LOL me too
[19:45:19] <robh_> haha
[19:45:19] <JT-Work> I got more done yesterday till my friends called my out to play :)
[19:45:31] <JT-Work> my/me
[19:45:31] <danimal_garage> robh_: for mcam??
[19:45:39] <robh_> ill let u do post then ill steal it ;)
[19:45:55] <robh_> for Camworks danimal_garage
[19:45:57] <JT-Work> ok
[19:46:03] <danimal_garage> i neeed a mastercam lathe post
[19:46:34] <robh_> i looked at mastercam post files didt look to hard to mod one up
[19:46:38] <danimal_garage> camworks... that's the solidworks cam software, right?
[19:46:54] <robh_> it runs inside solidworks yes
[19:47:05] <danimal_garage> wish i had that for my solidworks
[19:47:10] <robh_> made by Geometric
[19:47:30] <danimal_garage> pretty decent?
[19:47:31] <robh_> camworks is the other that runs inside solidworks also
[19:48:20] <robh_> i find it fills all my needs from 2D work to surfacing & multiaxes
[19:48:59] <robh_> nice not having to change programs all time also. mod the part is quick easy, and cam updates for u auto
[19:49:17] <danimal_garage> cool
[19:50:11] <danimal_garage> probably too rich for my blood
[19:50:17] <JT-Work> well sw is bitching at me to reboot
[19:51:16] <robh_> did u try the post on wiki for mcam
[19:51:32] <danimal_garage> i use the one for mill
[19:51:43] <danimal_garage> havent tried it for lathe yet
[19:51:54] <danimal_garage> same thing?
[19:52:09] <robh_> i dont know as i never used mcam
[19:52:31] <robh_> as its listed it looks like it , running x4 of mcam?
[19:54:45] <danimal_garage> x
[19:55:17] <renesis> guys what happened to microtech cncsim
[19:55:38] <renesis> like it wasnt lame enough i had to go get license gas every 3months, now the gas station doesnt email me at all
[21:10:55] <numen__> numen__ is now known as numen
[21:13:20] <frallzor> ok? :)
[21:39:27] <jt-plasma> at least it is 45F in the shop
[21:54:15] <Jymmm> This is an interesting chip... http://www.moschip.com/file_download.php?folder=MCS9901&fileid=Data%20Sheet_9901.pdf#
[21:55:23] <celeron55> that link requires login
[21:55:34] <Jymmm> bah, hang on
[21:55:56] <celeron55> you can find it on google easily, though
[21:56:12] <Jymmm> not the full datasheet you can't
[21:56:40] <celeron55> well, no-one is interested in reading a full datasheet of a chip randomly mentioned in irc 8)
[21:57:26] <Jymmm> * Jymmm smacks celeron55
[22:01:58] <tarzan> any datasheet reading tips?
[22:02:18] <Jymmm> it's coming, just being REAL slow

[22:09:24] <Jymmm> biteme
[22:11:41] <andypugh> The hal_input module uses usb devices of type "input" as far as I can see. I wonder if similar code would work with usb-hid devices?
[22:15:11] <andypugh> Specifically modifying jepler 's linux_event.py code
[22:15:58] <micges> I think it should work
[22:16:58] <andypugh> I might have a play then. I have a potentially useful USB-16xDIO chip that uses the USBHID protocol
[22:27:35] <tom3p> with all this nonsense on irc, i now get a new tab in pidgin labeled 'frigg' and a msg saying a ' CTCP was send by frigg to <me>'. is this more intrusions?
[22:28:50] <archivist> no frigg is a freenode services thing
[22:29:15] <tom3p> thx
[22:29:40] <Jymmm> Sounds like you have it set to notify you of system events
[22:30:41] <tom3p> thx, i dunno how, it wouldnt be something i chose, but might be something i didnt know to un-choose ;)
[22:41:23] <andypugh> "frigg" sounds a bit rude to me.
[22:42:24] <Valen> does kinda
[22:42:41] <andypugh> http://www.turoks.net/Bordello/GoodShipVenus.htm
[22:44:10] <Valen> damn that is dirty
[22:44:56] <andypugh> The Sex Pistols did a shorter but equally rude version.
[22:44:58] <tom3p> andypugh: nobody does dirty like sailors
[22:47:34] <andypugh> For fun, and 'cos it is too cold to play in the workshop, I have been messing with dual-motor homing for gantry use. http://www.pastebin.ca/1774895
[22:48:33] <andypugh> It needs work, the amp-enables need to latch after both switches close. Currently when one switch releases the other stops, and f-errors.
[22:53:24] <numen> is emc more powerfull, if i use an amd x2 cpu? now i use an p4
[22:54:55] <archivist> no
[22:56:07] <Valen> SMP can help though
[22:58:55] <andypugh> I am not sure why, but with my SMP kernel RTAI doesn't always exit cleanly, it leaves some modules stuck. (this might not be an SMP thing, probably more a module-compiled-by-a-fool thing). This is annoying as as well as preventing EMC restarting, it also stops the PC restarting (restart freezes after a trace-dump)
[23:00:37] <Valen> I havent seen that on mine
[23:00:44] <Valen> but then I haven't played with it too much
[23:01:10] <andypugh> That probably indicates that, unlike me, you are fit to be left alone with compilers.
[23:01:53] <andypugh> I would try to track down the issue, but the errors that scroll past on the screen are not logged to any of the logfies.
[23:02:57] <andypugh> It isn't a huge problem except when I am debugging a hal-file. It is when a hal-file fails to load because of an error that the problem most often occurs.
[23:04:20] <Valen> lol ‎I just followed the destructions
[23:04:23] <andypugh> Anyway, that is rather a digression from the topic at hand.

[23:12:17] <jt-plasma> http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/interface02.jpg
[23:12:22] <numen> archivist are u shure?
[23:12:31] <numen> if i compile it myself, too?
[23:13:04] <Valen> well what do you mean more powerfull
[23:13:14] <archivist> numen, how do you define powerful, the emc code remains the same
[23:13:54] <numen> archivist higher stepp frequence
[23:14:08] <skunkworks> jt-plasma: nice!
[23:14:38] <andypugh> That cabinet needs a huge knife-switch. It doesn't have to do anything.
[23:14:44] <archivist> too tidy not enough ratsnest
[23:15:02] <archivist> :)
[23:15:32] <Valen> its too tidy but still a bundle of wires
[23:15:45] <Valen> I've not yet worked out how you can avoid the bundle of wires
[23:15:55] <skunkworks> numen: what sort of step rate are you getting?
[23:16:19] <jt-plasma> thanks
[23:16:24] <jt-plasma> I'm getting there
[23:16:37] <numen> skunkworks 900mm/min with 12x3 tr and 400steps/u
[23:17:42] <numen> but there is an rtai error
[23:18:28] <skunkworks> waht is that in step frequency?
[23:18:37] <skunkworks> * skunkworks doesn't feel like doing math...
[23:21:49] <robin_sz> * robin_sz raises an eyebrow
[23:23:42] <robin_sz> is this thing on?
[23:23:48] <archivist> no
[23:24:08] <robin_sz> ah, didnt think it was ;)
[23:24:35] <archivist> hallo stranger anyway
[23:25:42] <robin_sz> hi :)
[23:25:54] <robin_sz> just thought id pop in ...
[23:26:06] <robin_sz> having one of those "i wish this router ran emc" moments
[23:26:27] <archivist> make it so then
[23:26:37] <robin_sz> I'd forgotten how much I hate proprietary CNCs
[23:26:58] <robin_sz> yeah, I got a wossit card sitting spare
[23:27:02] <robin_sz> might just do that
[23:27:33] <robin_sz> picked up a cheap Vytek Rebel 8x4 router
[23:27:53] <robin_sz> with a perfectly working controller
[23:27:58] <robin_sz> except ...
[23:28:15] <robin_sz> the manufacturer has, or declines to release any info
[23:28:26] <robin_sz> i think they might have forgotten how its driven
[23:29:15] <robin_sz> seems a shame to rip it apart . bt still, maybe the only way to get it running
[23:29:30] <robin_sz> so ... what new in the world of EMC?
[23:30:31] <archivist> hardinges are being converted all over the place
[23:31:16] <robin_sz> mmm .. lathes?
[23:31:22] <archivist> yes
[23:31:45] <robin_sz> ah yes, they did some plg board autos if I remember right?
[23:32:36] <robin_sz> jmkasunich lowered one into his basement yet?
[23:32:37] <archivist> dunno about plugboard except the emimec things
[23:33:05] <robin_sz> andypugh .. hmm name rings a bell
[23:34:28] <jt-plasma> on a phase converter if you need two start caps do you wire them parallel or series?
[23:35:08] <archivist> jt-plasma, parallel to add capacitance
[23:35:18] <andypugh> Hi robin :-)
[23:35:29] <numen> skunkworks how to calculate?
[23:35:32] <jt-plasma> thanks, that's got to be what is wrong
[23:35:39] <robin_sz> goodevening ...
[23:35:47] <robin_sz> why is your name familiar?
[23:35:53] <andypugh> I got disconnectulated
[23:35:58] <andypugh> Ixion
[23:36:02] <robin_sz> bloody hell
[23:36:17] <robin_sz> heh, smallll world
[23:36:25] <andypugh> Indeed.
[23:36:30] <robin_sz> I just re-subbed to Ixion last week :)
[23:36:50] <robin_sz> werent you racing lecky bikes last I heard?
[23:37:14] <numen> archivist how can i calculate the step frequency?
[23:37:18] <andypugh> No, though it looked like a lot of fun.
[23:37:38] <andypugh> Keef was very involved, and a few other Ixies based on the Island.
[23:37:38] <robin_sz> mmm, Im easily confused
[23:37:42] <robin_sz> yep
[23:37:52] <robin_sz> Keef + others
[23:38:27] <andypugh> I would have liked to have been involved, I think a lot of the Robotwars stuff would have carried over.
[23:38:40] <robin_sz> ah yes, indeed it would
[23:39:04] <robin_sz> im just getting back into normal life this year
[23:39:14] <archivist> numen, http://www.linuxcnc.org/docview/html/motion_tweaking_steppers.html
[23:39:14] <robin_sz> re-discoverign leisure time :)
[23:39:37] <andypugh> So what are you doing hanging out on a homebrew cnc software forum? That's hardly normal
[23:40:06] <robin_sz> oh, I used to be a very regular on here until I started an engineering business
[23:40:28] <andypugh> I know that.
[23:40:30] <robin_sz> but the recession cured me of that
[23:40:41] <robin_sz> back to writing software now
[23:40:49] <andypugh> Plasma cutters, but I understand that didn't work out?
[23:40:55] <jt-plasma> Sweet! I have the phase converter up and running and only 20v off without any run caps on the generated leg
[23:40:59] <robin_sz> oh, we diversified into sheet metal
[23:41:24] <andypugh> I made a step-up rotary convertor that almost worked.
[23:41:29] <robin_sz> had 13 odd staff, 8000 sq feet, two big trumph lasers, press brakes, welders, powder coating line etc
[23:41:35] <jt-plasma> archivist thanks
[23:41:48] <robin_sz> and then the orders ran out :)
[23:42:07] <andypugh> More free time to play with lasers then...
[23:42:15] <robin_sz> got my life back
[23:42:39] <robin_sz> we were doing around 1m a year or so, thats a lot of bits of metal
[23:42:47] <robin_sz> was knackering
[23:42:52] <robin_sz> mentally
[23:42:56] <andypugh> If you wire the motor Y, and put the neutral to the star point and spin it up with a smaller motor, you can get 3-phase and double the voltage.
[23:43:01] <robin_sz> so not sad when it folded really
[23:43:36] <andypugh> Yeah, I have always avoided success for just that reason.
[23:43:51] <robin_sz> yeah, well, osftware is way easier than bits of metal
[23:44:02] <numen> if i calculated right, i have 120khz, but i think, this is not possible?
[23:44:11] <robin_sz> you dont have to get up at 7am every morning to let it in :)
[23:44:37] <andypugh> I do software inside bits of metal.
[23:44:37] <robin_sz> and .. I might ask .. what are YOU doing hanging around a DIY cnc forum?
[23:44:55] <andypugh> I built a DIY CNC
[23:45:02] <robin_sz> sucker :)
[23:45:58] <robin_sz> making bits of bots on it?
[23:46:01] <robin_sz> bits of bikes?
[23:46:12] <andypugh> I decided I wanted to make a clock. Then I decided that all the gears and complex parts would be difficult without a bigger lathe and a mill, then decided it would all be tedious without CNC, and now I have rather forgotten why I started.
[23:46:21] <robin_sz> ah yes
[23:46:26] <robin_sz> that does happen
[23:46:53] <andypugh> Psst: Wanna buy some nice little servos and drives?
[23:47:07] <robin_sz> dribble
[23:47:25] <robin_sz> im trying to kick the habit
[23:47:46] <andypugh> So, naturally, you came here?
[23:47:51] <robin_sz> errr
[23:47:54] <robin_sz> ahh.
[23:47:57] <archivist> pwned
[23:48:02] <robin_sz> muchly
[23:48:13] <robin_sz> trying to help a friend with a CNC router
[23:48:18] <robin_sz> might have to EMC it
[23:48:28] <andypugh> Anything else would be a half measure
[23:48:34] <robin_sz> yeah
[23:48:43] <robin_sz> Vytek Rebel2
[23:48:43] <andypugh> Is it currently CNC?
[23:48:46] <robin_sz> yep
[23:49:05] <robin_sz> nice 8x4 machine
[23:49:50] <robin_sz> all works fine
[23:50:03] <robin_sz> jogs, parks, references
[23:50:13] <robin_sz> but ...
[23:50:13] <andypugh> So the problem is?
[23:50:26] <robin_sz> vytek have forgotten how the hell to send files to it
[23:51:02] <robin_sz> I finally found out its 19200 8E2
[23:51:06] <andypugh> Forgotten, or have chosen not to support any more/
[23:51:12] <robin_sz> but as for file format .. god knows
[23:51:14] <robin_sz> shrug
[23:51:18] <robin_sz> maybe the latter
[23:51:22] <andypugh> Not G-code then?
[23:51:25] <robin_sz> shrug
[23:51:27] <robin_sz> might be
[23:51:32] <robin_sz> or hpgl
[23:51:58] <andypugh> Logo? :-)
[23:52:21] <robin_sz> its *probably* a proprietary language called uCito
[23:52:24] <andypugh> How old is it?
[23:52:34] <robin_sz> 9 years I think
[23:52:44] <robin_sz> not that old
[23:52:48] <robin_sz> in good conitions
[23:52:58] <robin_sz> dc servos, encoders
[23:53:07] <robin_sz> 7hp 3p spindle
[23:53:15] <robin_sz> tool changer
[23:53:20] <andypugh> Is there a budget?
[23:53:29] <robin_sz> to get it going?
[23:53:38] <robin_sz> money, not a problem
[23:53:43] <robin_sz> time and effort is the issue
[23:53:46] <andypugh> Even working, having a proper PC with a hard drive is probably a good upgrade
[23:54:10] <robin_sz> yeah but the controller is fscking working .. its hard to rip it out when it works
[23:54:18] <robin_sz> got 8mb ram free
[23:54:27] <robin_sz> so it says as it powers up
[23:54:32] <robin_sz> so frustrating
[23:54:48] <andypugh> 8MB is quite a lot of G-code, when you think about it.
[23:54:57] <robin_sz> I feel like beating them to death with their own entrails
[23:55:25] <ds3> how do people handle the chuck mounting in a hardinage conversion? or do they just disable reverse?
[23:55:47] <robin_sz> right ...
[23:55:54] <robin_sz> nice to see you again da pugh
[23:56:05] <andypugh> What is the controller? Can you compile Linux for it?
[23:56:16] <robin_sz> nah, extratech.com
[23:56:25] <robin_sz> propieatry i960 based
[23:56:34] <andypugh> Sounds like a challenge.
[23:56:38] <robin_sz> got to go, but I *will* be back
[23:56:51] <andypugh> I will probably be here next time too. Have fun.
[23:56:58] <robin_sz> hehe, yeah
[23:57:01] <robin_sz> see ya
[23:57:33] <andypugh> Well, there's oddness for you.
[23:58:04] <tom3p> in hal, if i use a pyvcp panel AND have saved the hal configuration, how do i restart? i want to get the pyvcp test panel back AND the last configuration.
[23:59:13] <andypugh> OK, time I left too.
[23:59:24] <tom3p> (re the vytek, 8ne is weird for cnc, usually 7 and even cuz itrs ascii
