[01:26:09] <somenewguy> so I just blew up my brand new relay running it w/ my G540 board, anyone want to tell me where I fed up?
[01:29:41] <Jymmm> blew up?
[01:30:23] <somenewguy> well not really
[01:30:36] <somenewguy> but the coil now registers as an open circuit
[01:30:54] <Jymmm> and what does this relay do?
[01:32:40] <somenewguy> it was supposed to turn the spindle on and off
[01:32:56] <somenewguy> I got it out of a 12 volt air pump that I took apart, one of those ones you put in the trunk of your car
[01:33:06] <Jymmm> what kind of relay and how was it connected
[01:33:18] <somenewguy> my mill has a 24 volt psu so Iput a 420 ohm resistor between V+ and the coil
[01:33:28] <somenewguy> and connected the other side of the coil to the G540
[01:33:53] <somenewguy> Oh and I had a diode" backwards" across the coil as a simple flyback thingy
[01:34:33] <somenewguy> like an idiot I didn't bench test the setup because I don't have a PC in my shop w/ parallel, and it didn't occur to me to just short the wire that would go to the G540 to gnd
[01:35:11] <Jymmm> well, it was just a junk replay anyway, now just get a real 24v relay
[01:37:55] <somenewguy> So my cirucit was 24vcc, 420 ohm resistor,relay, G540
[01:38:16] <somenewguy> I tested the relay at 12v and it worked fine, I just didnt have a bnechtop 24 v supply or parralel pc
[01:38:52] <somenewguy> I have a bin of nicer 12v relays that I bought, I don't have any 24 v stuff lying around
[01:39:12] <somenewguy> I doubt radioshack would carry 24 v relays, what do yo uthink?
[01:39:24] <Jymmm> if you are gong to ghetto, might as well use two in series
[01:39:33] <somenewguy> hahaha
[01:39:44] <somenewguy> its not ghetto, I am just, uhhh, minimizing supply streams
[01:40:01] <Jymmm> G H E T T O
[01:40:10] <somenewguy> ghetto would be if I wired the spot light that came with the relay in series to drop the voltage
[01:40:27] <somenewguy> although come to think of it, I need another shop light....
[01:40:57] <somenewguy> is there anything inherently wrong with my design tho? Idon't get why it failed first try
[01:41:17] <Jymmm> go get damn 24v relay
[01:41:33] <somenewguy> I'll order one, but I want to know why it failed
[01:41:41] <somenewguy> hell I have a 24 relay right here actually, totally forgot about it
[01:41:48] <somenewguy> ...oh wait no
[01:42:00] <somenewguy> thsi one draws like 1.2 amps on
[01:42:15] <somenewguy> my psu is only 4 amps
[01:42:56] <Jymmm> 1.4A...sounds like a contactor
[01:43:07] <somenewguy> kinda, its a 250 amp relay iirc
[01:43:24] <Jymmm> thats NOT a relay
[01:43:25] <somenewguy> looks kinda like a big automotive relay, the old "ford relays"
[01:43:46] <Jymmm> contactor
[01:43:53] <somenewguy> it's not latching if that is what you are implying
[01:44:09] <Jymmm> nope
[01:44:10] <somenewguy> and I tried to shake a techincal deffinition of a contactor from the EEs at work and they couldn't give me agood one
[01:44:14] <somenewguy> so do you have one?
[01:44:25] <Jymmm> google it
[01:44:26] <somenewguy> they just said "it is like a relay but used for switching line voltages"
[01:45:27] <somenewguy> according to wikipedia a contactor is just a relay
[01:45:37] <somenewguy> has picked up a differnet name cause it is used in a different field
[01:45:47] <somenewguy> which was the conclusion I came to at work
[01:45:53] <somenewguy> do you disagree with that claim?
[01:46:24] <Jymmm> honestly, really dont care =)
[01:46:38] <Jymmm> you can cal it a freezer for all I care =)
[01:47:22] <Jymmm> usually a contactor is high amperage
[01:48:02] <somenewguy> well it deffinatly is that
[01:48:26] <somenewguy> was for an emergency kill circuit on a old robot that got demoted to 12 volts
[01:51:14] <somenewguy> just bugs me that it failed like that, even if it was a kludge i don't see why it would just pack in
[01:51:30] <somenewguy> but the fact it happened instantly makes me think it was a design error
[01:51:49] <somenewguy> if i'm going to waste an afternoon soldering and re-wiring, I want to at least learn from this rubbish
[01:52:09] <Jymmm> do the math
[01:52:25] <somenewguy> ?
[01:52:59] <Jymmm> ohms law
[01:53:06] <somenewguy> but I had a resistor in series
[01:53:11] <somenewguy> so the current was still the same
[01:53:12] <Jymmm> so?
[01:53:33] <Jymmm> 420 is almost s short circuit, not a voltage drop
[01:53:38] <Jymmm> 420 ohms
[01:53:49] <somenewguy> the coil was 420 ohms
[01:53:51] <Jymmm> not a 50% voltage drop
[01:54:00] <somenewguy> as was the resistor
[01:54:30] <Jymmm> it said 420 ohms on the relay?
[01:54:46] <somenewguy> measured it with a good DMM
[01:55:08] <Jymmm> you measured resistance, not impedance
[01:56:06] <Jymmm> what was the coil rated amperage?
[01:58:26] <somenewguy> unkown, it was only marked with 12v and the part number refused to turn up a datasheet
[01:59:53] <Jymmm> If it was 12V@0.5A = 6W
[02:00:13] <Jymmm> do you have a 3W resistor?
[02:02:14] <somenewguy> but it is DC
[02:02:19] <somenewguy> resistance is impedance
[02:03:15] <Jymmm> err inductance
[02:03:44] <somenewguy> doesnt matter if its dc tho
[02:04:25] <Jymmm> I fyou say so
[02:04:51] <somenewguy> am I missing something obvious?
[02:07:48] <Jymmm> you can't measure a coil with a DMM
[02:10:35] <uw> well, tech you can.
[02:10:40] <uw> to be that guy
[02:10:55] <uw> who chimes in when he's not asked to
[02:12:14] <somenewguy> I'll welcome the chime
[02:12:36] <somenewguy> I would think a crazzy inductive load might introduce some error, but I don't think a little relay would trick my meter
[02:12:53] <somenewguy> if you can link me any info sayign otherwise I'll eat my humble pie tho
[02:13:53] <uw> hmm well electronics are very linear so a crazy inductive load for one thing might not cause damage to another
[02:14:01] <uw> or visa versa
[02:14:07] <uw> vice versa?
[02:14:12] <uw> whatever it's called
[02:14:26] <uw> sorry, i mean "ARE NOT" very linear
[02:14:28] <uw> ugh
[02:14:48] <uw> i should have stayed silent
[02:15:46] <DaViruz> somenewguy: if it's a DC coil impedance equals resistance like you said
[02:16:16] <DaViruz> had it been AC it would be another story, i'm guessing that's what Jymmm is on about
[02:17:02] <DJ9DJ> moin
[02:17:03] <uw> GROIN DD
[02:17:14] <uw> like a damn bot
[02:17:14] <DJ9DJ> hi uw
[02:17:17] <uw> every, damn, day
[02:17:21] <uw> hi Deejay
[02:17:56] <somenewguy> yeah thats the case
[02:18:18] <somenewguy> I still don't know why the relay popped =(
[02:18:28] <uw> the coil?
[02:18:32] <somenewguy> yeah
[02:18:34] <uw> are you sure it's 12v?
[02:18:37] <somenewguy> it failed open the first time Itried to use
[02:18:39] <somenewguy> it
[02:18:47] <uw> and its a DC relay?
[02:18:49] <somenewguy> its a 12 v relay, marked on the relay
[02:18:57] <somenewguy> and I pulled it out of a 12 v tire pump
[02:19:02] <somenewguy> tested it, worked fine at 12 volts
[02:19:08] <somenewguy> coil was ~400 ohms
[02:19:31] <somenewguy> but my mil lhas 24 v psu, so I grabbed a 420 ohm resistor from my parts stash and wired it in series
[02:19:53] <somenewguy> hooke the other side of the coil to my G540, and it never worked
[02:20:01] <somenewguy> now the coil reads as open
[02:20:15] <uw> hmm sounds like could be a case of rush current
[02:20:24] <somenewguy> OH AN D i soldered a diode "backwards" across the coil because I thought I was supposed
[02:20:26] <somenewguy> to
[02:20:26] <uw> u made a voltage divider or just ran it in series
[02:20:50] <somenewguy> in series, resistor was very close to the same value as the coil resistance
[02:21:13] <somenewguy> so it was 24 V to 420 ohm resistor to 400 ohm coil to gecko output
[02:21:18] <DaViruz> imo that should have worked fine, double check that resistor
[02:22:10] <somenewguy> !!!!!!
[02:22:14] <somenewguy> just went to check it
[02:22:27] <somenewguy> there is now a short between the pole and one of the sides of the coil
[02:22:48] <DaViruz> what's a pole?
[02:22:49] <somenewguy> Im sorry no
[02:23:02] <somenewguy> there is an internal short between the NO pin and one side of the coil
[02:23:12] <somenewguy> not sure the proper name for it
[02:23:20] <Einar> That's quite common for some relays.
[02:23:27] <DaViruz> actually i would have expected a relay to work at least for a while at double the coil voltage
[02:23:38] <somenewguy> but the relay has 5 pins, coil, coil, NO, NC, and 'pole' as I decided to call it
[02:23:42] <somenewguy> is there a proper term for that?
[02:23:49] <DaViruz> common
[02:23:57] <DaViruz> common contact
[02:24:05] <somenewguy> 30
[02:24:08] <somenewguy> ok, common
[02:24:36] <somenewguy> well thank god the pin connected to the coil was not the one tied to 110...
[02:24:43] <DaViruz> what kind of voltages were you switching with this relay?
[02:24:44] <somenewguy> would have been a sad end to my G540
[02:24:51] <somenewguy> 110
[02:24:54] <somenewguy> it is rated for it
[02:25:02] <somenewguy> well, was rated for it I guess lol
[02:26:59] <DaViruz> are you measuring it in circuit? i guess it could read like that if your 24V supply is mains earthed
[02:28:05] <somenewguy> no, removed the relay and have it out on my bench now
[02:28:13] <uw> thatll teach it
[02:28:26] <somenewguy> it failed earlier in the day and I needed to get hte mill running again so I hacked it out and hardwired the damn thing on again
[02:28:46] <somenewguy> the sad thing is I just tore down my brand new-to-me mill to rebuild adn ajust the gibs and ADD THIS FRACKING RELAY
[02:29:03] <somenewguy> back to using a lightswitch on the side of the spindle to turn it on and off
[02:29:10] <somenewguy> what am I, a caveman?
[02:29:34] <uw> just strip the wires and jam them into the socket for pete sake
[02:29:44] <uw> barbarian
[02:30:37] <somenewguy> I have a new relay from a different supplier right here....
[02:30:42] <somenewguy> to try again or not is the question
[02:30:57] <somenewguy> this circuit should work, mabye I'll leave the flyback diode out this time tho
[02:31:18] <somenewguy> I would assume the G540 was designed with inductive loads in mind, and this is a much much smaller load than it can handle
[04:46:13] <JesusAlos> hi people
[04:48:03] <JesusAlos> what is the use of .var files in configration folder?
[05:51:14] <jthornton> http://linuxcnc.org/docs/html/gcode/overview.html#_numbered_parameters_a_id_sub_numbered_parameters_a
[05:53:19] <jthornton> JesusAlos, ^^
[06:16:18] <JesusAlos> yep
[06:16:20] <JesusAlos> hi
[06:19:28] <Jymmm> vermiculite isn't flammable, interesting
[06:55:20] <JesusAlos> how can I move the axis with keypad?
[06:55:40] <kengu> what pad? arrows?
[06:55:53] <JesusAlos> yes arrows or letters
[06:56:11] <JesusAlos> the key pad of PC
[06:56:12] <Jymmm> and PGUP / PGDN
[06:56:20] <kengu> was there a question?
[06:56:36] <kengu> left, right, up, down and pgup, pgdown
[06:56:45] <kengu> that gives you xyz
[06:56:47] <JesusAlos> the question is if linuxcnc can associate this
[06:57:01] <kengu> does it out of the box
[06:57:01] <JesusAlos> ok
[06:57:05] <JesusAlos> sorry
[06:57:10] <JesusAlos> it run
[06:57:32] <JesusAlos> my idea is connect a usb wireless pad
[06:58:53] <archivist> you need a good excuse to use wireless as it can be unreliable
[06:59:11] <JesusAlos> I know is good idea
[06:59:24] <Jymmm> bad idea
[06:59:45] <JesusAlos> sorry. not good. yes
[06:59:49] <Jymmm> =)
[06:59:52] <JesusAlos> but can test it
[06:59:57] <archivist> there is NO wifi near any of my machines
[07:00:00] <JesusAlos> need test it
[07:00:05] <Jymmm> but you'll shoot yourself in the foot anyway, gotcha
[07:02:31] <kengu> i backed the smoothieboard on kickstarter, http://www.kickstarter.com/projects/logxen/smoothieboard-the-future-of-cnc-motion-control and as it is at $17000 of $20000 in one day and still 15 to go I will (most probably) end up with one
[07:03:47] <kengu> then I can put it in one of the machines I don't have yet or in one of the ones I have
[07:11:47] <JesusAlos> don't have graphical interface?
[07:16:53] <JesusAlos> I'm going to eat Paella Valenciana
[07:17:13] <JesusAlos> "que aproveche"
[07:34:32] <archivist> a real toy at the right price 151132630198
[08:08:45] <kengu> JesusAlos: graphical in what?
[09:18:38] <archivist> hmm the GTE v Rolls Royce fight over probing (Renishaw being mentioned as co owners of RR patent)
[09:58:44] <Tom_itx> anybody remember the hall sensor andy used on his spindle head?
[10:24:09] <jp_mill> has anyone seen the siemens 808D control?
[10:24:32] <JT-Shop> no
[10:24:53] <jp_mill> it's a new low end sinumerik control
[10:25:28] <JT-Shop> at least the spammer posted in the off topic section
[10:25:37] <jp_mill> they claim it's closed loop but the contol itself only sends step dir out to drives
[10:26:07] <jp_mill> i assume they tjust run the drives in position mode
[10:26:48] <jp_mill> was wonder what it might be like to try that with my mill and lcnc
[10:30:29] * JT-Shop heads out for a Mystery Ride that is sure to end up kinda wet
[10:42:50] <archivist> jp_mill, lcnc is a control, why would you want that as well
[11:02:44] <somenewguy> doess anyone in here also use mach3?
[11:04:18] <somenewguy> alternatly, does anyone in here use a G540 drive, and know if in linuxcnc I can diable my 4th axis and use the step and dir pins as extra outputs?
[11:05:23] <archivist> just use the parallel port or bob direct
[11:06:32] <somenewguy> so I would have to "liberate" the two wires from the G540 connection
[11:07:21] <kengu> that is what i would do
[11:07:40] <kengu> make a BoB to pass all the others and preserve those two
[11:11:59] <archivist> step and dir pins are inputs anyway
[11:15:08] <somenewguy> ah, BoB is not an acroynim I recognize immediatly
[11:15:26] <somenewguy> fortunatly I already have a tool to do so
[11:15:33] <somenewguy> assuming the gedner is right
[11:16:19] <archivist> it is the part that converts parallel to the drives step dir inputs
[11:16:20] <somenewguy> archivist, depends on perspective. I wanted to control a relay, and I already have a board to control a relay using logic level signals assuming my LPT is 5v not 12
[11:16:39] <archivist> LPT is never 12v
[11:16:42] <somenewguy> bob is just a breakout board
[11:16:44] <somenewguy> ?
[11:16:48] <archivist> yes
[11:16:54] <somenewguy> I thought is used to be 12, or am I thining of serial
[11:16:59] <somenewguy> err RS232
[11:17:11] <archivist> serial/rs232 uses 12v
[11:17:15] <somenewguy> which is anything over 3.somethign- counts as high
[11:17:28] <somenewguy> which used to be up to 12, but now is basically always only 5 tops
[11:18:04] <somenewguy> but it sounds like I would need to mangle the setup a bit, I will just continue ot try and figure out why the hell my relay broke last night
[11:18:08] <archivist> it is not proper rs232 without a 12v source
[11:18:20] <somenewguy> and just order a PCI-parallell card for my extra IO needs
[11:18:36] <somenewguy> proper, maybe not, but it meets the minimum of the standard IIRC
[11:18:43] <archivist> did you put your relay on the 4 axis drive?
[11:18:46] <somenewguy> ie it only defines a minimum high level
[11:18:56] <somenewguy> no, I was thinking about it
[11:19:11] <somenewguy> wasting one of my open collecter outputs seeemd like a waste
[11:19:11] <archivist> minimum with a defined load, that means 12v
[11:19:32] <somenewguy> I will trust you on that, I deffinatly don't konw the standard that well, thank god for wikipedia
[11:20:21] <archivist> bad implementations claiming to be to "a standard" are a pain
[12:12:31] <IchGuckLive> hi all B)
[12:13:36] <kengu> hello
[12:14:24] <IchGuckLive> JesusAlos: ?
[12:18:23] <IchGuckLive> kengu: why dident you point jesus to the gampad to move the axis and some bottons
[12:19:17] <IchGuckLive> wiki got lots of examples also on my youtube channel all in full detail howto
[12:21:12] <kengu> IchGuckLive: i thought i did
[12:21:59] <IchGuckLive> logs from today does not indikate that
[12:22:26] <IchGuckLive> ok he is on its own but about 50feet from his store he will get the pad
[12:24:13] <kengu> or more accurately I think the problem was solved and thus no need for extra hardware
[12:24:17] <kengu> what ever.
[12:24:59] <IchGuckLive> i see
[13:37:24] <JesusAlos> hi
[13:39:41] <kengu> helou
[13:40:23] <JesusAlos> kengu: what refer IchGuckLive?
[13:40:56] <JesusAlos> is concret mark of pad?
[13:43:27] <kengu> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant this or what? i am having hard time understanding your problems
[13:43:52] <archivist> he claims the remote pendent is ok yet at the same time he was in the other channel trying to reset the usb connection because it fails
[13:44:33] * kengu shuts up
[13:44:53] <mhaberler> ah, easy : Interp() : _setup(setup_struct())
[13:49:39] <CaptHindsight> pcw_home: for non-real time applications have you ever tested the USB transfer rates when using multiple 7143H's in one system?
[14:33:48] <JesusAlos> kengu: Sorry, but my English is not very good, as you see.
[14:34:50] <JesusAlos> will try to improve
[14:34:56] <uw> the jesus
[14:35:27] <uw> aka El Jesus
[14:37:44] <JesusAlos> Ese soy yo :)
[14:46:21] <JesusAlos> uw: de donde eres?
[14:47:55] <uw> usa y tu?
[14:50:32] <JesusAlos> Spain
[14:53:02] <uw> España lo que veo Alguna vez has oido hablar de los motores Mavilor?
[14:53:18] <uw> "Sta. Perpetua de Mogoda
[15:07:11] <JesusAlos> never
[15:07:20] <JesusAlos> are good motors?
[15:32:14] <uw> Yo no los he usado todavía. Necesito documentación de ellos.
[15:39:25] <JesusAlos> estan cerca de mi casa si te puedo ayudar en algo me lo dices
[16:01:23] <jp_mill> archivist: I did not want the sinumerik control just thought it odd they were marketing what was essentially an open loop cnc controller. I was just wondering what that kind of setup would perform like
[16:02:31] <jp_mill> in the end i guess it's no different than a stepper machine just using ac servos
[16:04:59] <DaViruz> at least you (possibly) get an error if it's out of possition
[16:05:24] <DaViruz> but it does seem odd that siemens released something like that
[16:05:35] <jp_mill> The only way it would get an error is via a drive fault
[16:05:46] <DaViruz> yeah
[16:05:54] <jp_mill> the control has no feedback input
[16:06:03] <DaViruz> i get that
[16:06:36] <jp_mill> it's supposed to be marketed against centroid and acurite type controls
[16:06:51] <jp_mill> the control is only $3500
[16:06:59] <DaViruz> i spent the better part of today mesing around with my 810M
[16:07:04] <DaViruz> and then 20 minutes machining
[16:07:17] <DaViruz> i might end up having to slam linuxcnc on that thing
[16:07:20] <jp_mill> to bad you could not load lcnc on an 808d hardware
[16:08:03] <jp_mill> the siemens MCP for the 808d is usb and cost $250
[16:09:12] <jp_mill> would make a great control panel for a lcnc setup if it could be hacked.
[16:12:09] <jp_mill> I'm almost at that point with my fanuc om-c

[16:19:15] <JesusAlos> for download linuxcnc source code, must be by git method?
[16:19:31] <JesusAlos> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_EMC2#Getting_the_source_with_git
[16:19:51] <JesusAlos> or there are other direct way?
[16:34:46] <kengu> JesusAlos: look at 5. in that doc
[16:34:57] <kengu> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_EMC2#Other_ways_of_getting_the_source_code
[16:43:36] <CaptHindsight> http://wiki.linuxcnc.org/uploads/mesanet_7i43_with_jtag_connector.jpg are PIN #1 for the P3 and P4 connectors in the lower left corner of the connectors in this pic?
[16:44:47] <CaptHindsight> ODD numbers in the lower half of the connectors and EVEN numbers in the top?
[16:44:58] <CaptHindsight> I don't have one handy at the moment
[16:45:43] <kengu> http://www.ebay.com/itm/CNC-Single-Axis-TB6600-0-2-5A-Two-Phase-Hybrid-Stepper-Motor-Driver-Controller-/271286744345 ..cheap.
[16:54:52] <JesusAlos> gn8
[16:54:56] <JesusAlos> thank
[17:09:39] <DaViruz> has anyone played around with linear encoders with distance coded index marks?
[17:10:13] <DaViruz> basically the scale has index points every 10mm or so, each with unique spacing
[17:10:29] <DaViruz> so you only need to pass two of them to get an absolute reference
[17:11:03] <CaptHindsight> or a closer reference
[17:12:00] <CaptHindsight> I have some analog types like that with index every cm or so
[17:12:17] <DaViruz> analog, how does that work?
[17:12:25] <DaViruz> i haven't really checked the output of these
[17:13:21] <CaptHindsight> http://www.renishaw.com/en/rgh24-linear-encoder-system--6444
[17:13:55] <DaViruz> oh
[17:14:04] <DaViruz> 10nm resolution, that's.. ridiculous
[17:14:36] <CaptHindsight> not accounting for temperature changes
[17:15:23] <DaViruz> these are heidenhain scales, LS107
[17:15:27] <CaptHindsight> a short length of aluminum might expand by a few microns over a 20 deg change
[17:15:31] <pcw_home> Pretty sure the Renishaw ones are invar
[17:15:40] <DaViruz> TNC355 controller which is getting a bit crusty and unreliable
[17:15:52] <CaptHindsight> hi pcw
[17:16:07] <CaptHindsight> http://wiki.linuxcnc.org/uploads/mesanet_7i43_with_jtag_connector.jpg are PIN #1 for the P3 and P4 connectors in the lower left corner of the connectors in this pic?
[17:16:11] <DaViruz> but the short distance homing is very nice, and i'd like to keep that if it's to be retrofitted
[17:17:52] <pcw_home> Cant remember off hand If you look at back of card, PIN 1 has a square pad
[17:18:29] <CaptHindsight> pcw_home: heh, I don't have the card handy and I'm sitting here with Allegro ready to make some gerbers for a custom board
[17:18:58] <pcw_home> standard header polarization
[17:19:16] <CaptHindsight> pcw_home: ok, just checking
[17:19:24] <CaptHindsight> some people get fancy
[17:19:54] <jp_mill> pcw_home: on a 7i77 with the db25 cable unpluged and W5 to the right my 5v supply gets draged down
[17:20:10] <jp_mill> any thoughts
[17:20:22] <CaptHindsight> pcw_home: ever test multiple 7i43's on separate USB controllers on a single motherboard?
[17:21:05] <pcw_home> No but its unlikely to work very well as multiple USB "porta" are usually just hubs
[17:21:12] <pcw_home> ports
[17:21:34] <CaptHindsight> pcw_home: this is a chipset with multiple controllers
[17:22:08] <CaptHindsight> they split the controllers into 4 ports each with hubs
[17:22:22] <CaptHindsight> but this has 4 or 5 controllers
[17:22:37] <CaptHindsight> something like 20 USB ports total
[17:23:25] <pcw_home> jp_mill you mean external 5V wont run 7I77 by itself?
[17:23:41] <jp_mill> yes
[17:23:57] <jp_mill> its a 5A supply as well
[17:24:12] <CaptHindsight> pcw_home: another option is the 6i68 + 3x20. What's the maximum sustained data transfer rate into the FPGA?
[17:24:27] <jp_mill> but was running fine off of the 5i25
[17:24:32] <pcw_home> about 150 MB/sec
[17:24:46] <pcw_home> reverse polarity?
[17:25:15] <jp_mill> according to all of the labels no but checking with dmm now
[17:26:00] <jp_mill> poarity is fine
[17:26:00] <pcw_home> make sure you have both the 5i25 and 7I77 jumpered for external 7I77 power
[17:26:24] <jp_mill> i kept the 5125 unpluged first
[17:26:42] <jp_mill> and checked set the jumpers on it as well
[17:27:11] <pcw_home> short on external 7I77 connections?
[17:28:21] <jp_mill> thats what bothers me it was ok running off of the 5i25 30 min ago
[17:28:45] <jp_mill> was just trying to see if my count issue was due to low 5V power from 5i25
[17:29:07] <jp_mill> going to set it back and see what happens
[17:32:27] <CaptHindsight> pcw_home: actually 8 USB host controllers, 16 ports
[17:33:20] <cmorley> Daviruz: It would require some changes in linuxcnc to use distance coded reference encoders AFAIK.
[17:33:32] <CaptHindsight> pcw_home: are there any issues with using 2 of 6i68's in the same MB?
[17:34:17] <cmorley> linuxcnc assumes reference after home is zero rather then what ever the encoder says
[17:34:27] <CaptHindsight> if you have the slots and mechanical space
[17:34:33] <DaViruz> cmorley: that's what i figured :/
[17:35:16] <cmorley> I agree it would be nice and is doable, just a simple case of coding...:)
[17:35:30] <cmorley> I have on but have not tried it.
[17:36:23] <pcw_home> There shoud be no issue with using as many as you have slots for
[17:36:48] <jp_mill> pcw_home: looks like the 7i77 is toast
[17:39:45] <CaptHindsight> pcw_home: thanks, I would need 10MB sustained isochronous USB transfers for 3 - 15 devices for each device
[17:42:18] <Tom_itx> andypugh, do you remember the PN for the hall sensor you used on your spindle?
[17:42:30] <Tom_itx> ( i think it was on a spindle )
[17:46:33] <jp_mill> pcw_home: i stand corrected the 7i77 is fine
[17:46:50] <jp_mill> everything works fine off of the 5i25
[17:47:40] <jp_mill> should i not beable to unplug the db25 cable and set the jumper to external 5v and see the led's on the 7i77 come on?
[17:49:00] <pcw_home> Yep
[17:50:12] <jp_mill> think i found the issue
[17:50:27] <jp_mill> I think there is a mistake in the manual
[17:51:08] <jp_mill> when i use a dmm to measure the voltage on TB1 of the 7i77 conected to the 5i25 the polarity is wrong
[17:51:43] <jp_mill> manual says pin 1 is gnd and 2 is +5V
[17:52:44] <jp_mill> dmm reads pin 1 as +5v and pin 2 as gnd
[17:59:00] <jp_mill> pcw_home: Yep that was it. Reversed polarity on external PSU and it powers the 7i77 fine. The manual has pins for TB1 inverted.
[18:02:29] <micges> jp_mill: there should be info onboard about TB1 polarity
[18:02:51] <jp_mill> what do you mean?
[18:03:33] <micges> do you have +5V desciption near TB1?
[18:03:49] <jp_mill> there is no silkscreen for tb1
[18:04:00] <jp_mill> atleast not on my board
[18:04:02] <micges> oh
[18:04:18] <jp_mill> thats why i went by the manual
[18:05:21] <jp_mill> all is fine now i'm happy i figured it out without letting out the majic smoke
[18:06:56] <micges> do you have revision printed onbard?
[18:08:04] <jp_mill> i have it in one of those extruded plastic din rail board holders so i would have to pull it all out and that's a PITA
[18:08:25] <jp_mill> I've had this board for at least 2-3 years now
[18:09:11] <pcw_home> If it has no silkscreen power markings you must have a proto!
[18:09:36] <jp_mill> im pretty sure i got this one when you first launched them
[18:10:48] <jp_mill> is there a board art level mark on the front of them?
[18:11:01] <pcw_home> Yeah the protos had reversed power
[18:11:42] <pcw_home> top right (I think current rev is C anything unmarked is a proto)
[18:12:08] <jp_mill> ok so manual is good and i just need to remember mine is at proto level
[18:13:05] <jp_mill> any other gotchas i should be cognisant of?
[18:14:43] <jp_mill> BRB gotta shut down to switch some jumpers
[18:24:12] <jp_mill> hmm: cant figure out if i have a scaling issue or a mechanical issue.
[18:25:20] <jp_mill> Does not seem to be backlash
[18:25:42] <CaptHindsight> pcw_home: are there any 50 pin AnythingIO daughter cards that don't work with the 6i68?
[18:29:15] <pcw_home> I dont think so
[18:29:35] <CaptHindsight> great, it looks like the safer way to go with room for expansion
[18:30:03] <uw> are there discount price for buying 5i25 and 7i77?
[18:30:32] <CaptHindsight> 8-15 7i43H's in one system is probably asking too much from the USB controllers
[18:30:56] <pcw_home> I think you get both and the cable for a giant $10.00 off
[18:31:46] <uw> i see
[18:32:44] <pcw_home> looking at 7i77 proto issues: (from 7i77.isu)
[18:32:45] <pcw_home> TB1 polarity is wrong, should be reversed.
[18:32:46] <pcw_home> u24 unused input needs termination
[18:32:48] <pcw_home> FIELD IO VBUS tap PLANE error
[18:32:49] <pcw_home> Aout5 needs ENASP not AENA
[18:32:53] <CaptHindsight> I still need to make a custom breakout board for the 50 pin anythingIO, but it should also work with the 7i43
[18:35:02] <jp_mill> ok. i have a bp clone mill with ac servos on x and y drives are setup for torque mode. on both axis if i jog .100" increments in one direction i get readings on my heidinhain dro, .098,.102,.098,.102 always in that pattern
[18:38:11] <archivist> something bent?
[18:38:39] <archivist> what is the pitch of the screw
[18:38:45] <jp_mill> i would have to check but on both axis?
[18:39:00] <jp_mill> .200" per rev
[18:39:38] <archivist> the error is half a rev
[18:39:48] <archivist> at half a rev
[18:40:08] <uw> i think i have read something about that
[18:40:12] <uw> with those numbers
[18:40:18] <archivist> a drunk rolled ballscrew?
[18:40:22] <uw> i think it was because the screw was actually metric
[18:40:29] <uw> i'll look for it
[18:40:43] <jp_mill> these are ground preloaded hiwin's
[18:41:08] <uw> that .098 sounds familar but i could be thinking of something else
[18:42:31] <jp_mill> well maybe they are 5mm pitch
[18:43:02] <jp_mill> guess i can calc scale using 5mm pitch and check
[18:44:27] <archivist> the number sequence you gave is not one way
[18:45:02] <archivist> or was that two sequences and a scale error
[18:45:13] <jp_mill> one way
[18:45:20] <jp_mill> moving in one direction
[18:46:10] <archivist> why the huge drop .102 to .098 mid sequence .098,.102,.098,.102
[18:46:23] <archivist> I expect .2 xxx
[18:46:40] <archivist> .3 .4 I mean
[18:47:17] <archivist> do it for a whole inch on one axis
[18:47:43] <jp_mill> ok one sec
[18:50:39] <jp_mill> .100,.202,.300,.402,.500,.602,.700,.802,.900,1.002
[18:51:26] <jp_mill> same in the revers direction
[18:53:55] <uw> i cant find anything about it sorry
[18:55:33] <archivist> the sequence for a metric screw should not be that consistent in inch error
[18:56:33] <archivist> you missed the 0 point, I would also check over a much longer distance
[18:57:22] <CaptHindsight> pcw_home: is PIN #49 always POWER? The 7i43 lists it that way but the 6i68 only lists the signals up to pin #47.
[18:57:59] <pcw_home> pin 49 is always 5V or 3.3V power (selectable)
[18:58:15] <CaptHindsight> thanks
[18:58:26] <pcw_home> and all even pins are always GND
[19:00:46] <CaptHindsight> page #3 of the 6i68 mentions it, I was just looking at the pinout pages
[19:03:49] <jp_mill> archivist: if i run a warmup program multiple times i always end up in the same spot as well. according to my dro.
[19:04:02] <andypugh> Tom_itx: The same ones as Jon Elson used. The only source I could find was eBay. http://www.ebay.com/itm/5pcs-ATS667LSGTN-T-Gear-Tooth-Sensor-IC-/161045445299?pt=LH_DefaultDomain_0&hash=item257f0e7ab3
[19:05:12] <Tom_itx> no magnet required?
[19:05:27] <archivist> jp_mill, consistency (back to same point) is not a proof of accuracy
[19:06:03] <andypugh> Tom_itx: Yes, that is the unique thing about those, Avago already add the magnet.
[19:06:13] <archivist> jp_mill, just means no lost steps or lost motion etc
[19:06:24] <Tom_itx> that's what i remembered about it...
[19:07:11] <jp_mill> archivist: i understand that. so i'm trying to figure our why i'm not accurate. i think i can rule out backlash
[19:07:25] <archivist> jp_mill, what type of drives? are they step dir to the servo?
[19:07:36] <Tom_itx> andypugh, did you make up a board for it?
[19:07:38] <jp_mill> no, analog
[19:08:17] <andypugh> Tom_itx: No, they connect straight to +5V 0V and GPIO.
[19:08:20] <archivist> jp_mill ok what encoder resolution
[19:08:29] <jp_mill> 2000ppr
[19:08:30] <Tom_itx> oh that's cool
[19:10:06] <jp_mill> archivist: motors are conected to screw via 3:1 timing belt
[19:12:36] <archivist> timing belt pitch error ?
[19:12:39] <Tom_itx> andypugh, is it quadrature? why the 2 output signals?
[19:13:43] <jp_mill> archivist: i was wondering that myself. Think i should just tweak input scale to tune in?
[19:14:14] <Tom_itx> andypugh, http://www.digikey.com/product-detail/en/ATS667LSGTN-T/620-1328-6-ND/2042763
[19:14:25] <archivist> jp_mill, if you take a few thousand measurements and do a fourier transform you will see all the error frequencies from the various sources
[19:14:26] <andypugh> Tom_itx: There is a "test" pin. Generally left unconnected. (probably analogue level)
[19:14:46] <archivist> jp_mill, that is not a scale error thought it is regular
[19:15:49] <Tom_itx> did you mean Allegro instead of Avago?
[19:15:59] <Tom_itx> search on the PN brought that up
[19:17:42] <archivist> jp_mill, is it just a case of adjusting the belt tightness
[19:20:52] <archivist> anyway cyclic errors in gearing(belt/chain) need mechanical fixes or compensation, lcnc has screw compensation but not for cyclic errors as far as I know
[19:20:52] <jp_mill> they feel good right now
[19:21:18] <jp_mill> so i changed my mpg to increment at .066667
[19:21:35] <jp_mill> 1 rev / 3
[19:22:55] <jp_mill> now on the dro i get .062,.062,.077
[19:23:06] <jp_mill> in one direction
[19:23:27] <jp_mill> and when i reverse i get .077,.062,.062
[19:25:02] <archivist> I would be comparing axis readout to the dro,
[19:25:35] <andypugh> Tom_itx: Yeah, A* (whoever makes them)
[19:25:38] <jp_mill> axis always says it moved what i asked for
[19:25:52] <Tom_itx> cool, appears digikey has them now
[19:26:54] <andypugh> I don't think Digikey will sell to me.
[19:27:01] <Tom_itx> why not?
[19:27:10] <Tom_itx> uk?
[19:27:14] <andypugh> I live on the wrong continent
[19:27:20] <archivist> jp_mill, your 3:1 is three revs motor to one screw?
[19:27:40] <jp_mill> yes
[19:28:11] <archivist> which means 6k encoder pulses per rev of the screw ish
[19:28:28] <jp_mill> yes
[19:30:19] <archivist> so a 10" travel is?
[19:30:58] <archivist> can you also check with slips etc
[19:31:50] <archivist> andypugh, I think they sell over here
[19:32:17] <jp_mill> archivist: 150 motor revs
[19:32:33] <andypugh> Mouser do, at a very small penalty, Digikey will certainly sell me stuff, but the pricing is frightening.
[19:32:46] <Tom_itx> mouser doesn't carry allegro unfortunately
[19:33:31] <archivist> they have a uk 0800 number
[19:34:36] <andypugh> Maybe they woke up to the idea that folk in the UK have money too? I last tried to use them a while ago.
[19:34:40] <archivist> jp_mill, I meant the distance
[19:34:56] <jp_mill> oh in counts
[19:35:01] <archivist> I have had catalogues off them over here
[19:35:17] <archivist> jp_mill, no in distance
[19:35:27] <jp_mill> oh one sec
[19:37:35] <archivist> with some care you can use a digital vernier as an independent dro
[19:38:01] <jp_mill> i have an independent dro
[19:38:15] <jp_mill> its 9.998
[19:38:20] <archivist> I mean independent of that possibly faulty one
[19:38:26] <jp_mill> ah
[19:39:11] <jp_mill> well i check the dro against a dial gauge and they both agreed
[19:40:49] <jp_mill> thats why i was trying to power the 7i77 externally. eairler in the week i was chatting with pcw and he was thinking i may have been loosing counts
[19:41:08] <andypugh> Oooh! HXL? £10? http://www.ebay.co.uk/itm/CNC-Lathe-/151132630198
[19:41:32] <archivist> I didnt notice that discussion, but returning to the same point say that is not the problem
[19:42:27] <jp_mill> no i do bot believe it is. Just was ticking off one possible check box
[19:42:27] <archivist> andypugh, I poked that in channel at a 99p this morning
[19:44:16] <andypugh> It's certainly worth at least £11
[19:44:24] <archivist> jp_mill, I have seen cyclic errors in the gearing that was very bad in a rotary, I think you need to graph, say every 10 thou, for say an inch to see it
[19:44:57] <archivist> the carriage to the mainland is a little more costly
[19:45:26] <CaptHindsight> http://www.digikey.co.uk/ where do they actually stock the parts?
[19:46:12] <andypugh> Yes, though I do go there, with a truck, most years. And have contacts in the historic truck scene on the island
[19:46:31] <archivist> go fetch :)
[19:47:53] <andypugh> Funny day today. I spent the whole day ferrying fresher science/engineering students around South Kensington on a 1916 fire engine.
[19:48:14] <archivist> I went nowhere :(
[19:48:28] <Tom_itx> did you wear your fire hat?
[19:48:57] <andypugh> We accidentally ran over the brass helmet a few years ago.
[19:50:39] <Tom_itx> would that sensor work on regular gear teeth?
[19:50:56] <Tom_itx> not large gears...
[19:50:57] <andypugh> Tom_itx: Definitely.
[19:51:01] <Tom_itx> smaller ones
[19:51:19] <Tom_itx> like you would see in a small gearhead etc
[19:51:38] <andypugh> Hang on, define "regular" Gear teeth are by their nature regular, or they don't work.
[19:51:38] <Tom_itx> 24tpi or such
[19:52:12] <Tom_itx> i could file off every other one i suppose
[19:52:15] <archivist> jp_mill, the error graph peaks should be at the frequency of the faulty item(timing pulley eccentric) or an aliased mix if it is the teeth on the belt
[19:52:22] <Tom_itx> thinking of something smaller for my sherline
[19:52:36] <Tom_itx> the ir sensor i have works but it's not ideal
[19:53:34] <andypugh> http://www.ebay.co.uk/itm/2pcs-6-36VDC-300mA-8mm-Approach-Sensor-Inductive-Proximity-Switch-LJ18A3-8-Z-BX-/281174894890?pt=LH_DefaultDomain_3&hash=item417754692a might work
[19:53:48] <andypugh> but 24tpi is pretty tiny
[19:54:09] <jp_mill> archivist: Thanks
[19:54:15] <Tom_itx> well i could knock off a few teeth
[19:54:47] <Tom_itx> i tried to remove the wheel off an auto wheel bearing to no avail
[19:55:13] <archivist> some force required
[19:55:44] <Tom_itx> much
[19:56:14] <Tom_itx> more than i had available
[19:56:42] <eric_unterhausen> how do you run a python program from the interpreter?
[19:56:49] <archivist> I some times dremel a groove to crack the bearing
[19:56:59] <andypugh> There are gear tooth sensors with very small points, but they don't work DC>
[19:57:28] <andypugh> eric_unterhausen: Call it as ab M199 custom code
[19:57:59] <eric_unterhausen> sorry, should have mentioned I am at zero for python programming
[19:58:06] <eric_unterhausen> I mean from python interpreter
[19:58:28] <andypugh> So, you want to call a program you don't know how to write?
[19:58:29] <eric_unterhausen> apparently it's import myprog
[19:58:59] <andypugh> Ah! _that_ interpreter!
[19:59:02] <eric_unterhausen> all the tutorials tell you how to write the program, but not how to run it
[20:02:58] <jp_mill> thats the nice thing about python

[20:04:32] <jp_mill> funny
[20:10:11] <andypugh> Not a bargain: http://www.ebay.co.uk/itm/Albrecht-3-to-16-mm-Keyless-drill-chuck-on-3-MT-Similar-to-Rohm-/151127145942
[20:10:48] <CaptHindsight> http://3dprintingindustry.com/2013/09/30/australias-giant-3d-printer/ heh, I can see the silliness of whose is bigger starting
[20:10:51] <andypugh> Yes, gouging out the crack and welding will really leave that chuck like new, won't it?
[20:11:25] <archivist> seller looking for an idiot
[20:12:23] <andypugh> Wasn't there a concrete pump to 3D print houses? Suely that wins so far?
[20:12:35] <jp_mill> if that's how he fixes tools i'd like to see what kind of shape his machines are in.
[20:12:51] <CaptHindsight> yeah, if you want to expand to all the different tech, not just glue guns
[20:13:07] <andypugh> archivist: Shrinking on a sleeve, however, probably would work.
[20:13:57] <andypugh> Pity this is too small: http://www.ebay.co.uk/itm/ALBRECHT-DRILL-CHUCK-HOOD-70722-FOR-MODEL-C65-NEW-/151019711580
[20:14:32] <andypugh> Anyway, I am off of eBay drill chucks, so far I have oredered 2 and neither have arrived.
[20:16:12] <andypugh> One is probably at a parcel depot, but with no card, it is hard to guess which. The other was sent to the wrong chap in an unfortunate parcel-switch, and whilst I posted his to him. it seems he didn't post mine to me..
[20:17:18] <andypugh> "The ART 3D Printer, the heavyweight champion of Australia, will go on sale in October of this year. They’re still working out the price, but are sure that it will be less than $100K."
[20:17:42] <archivist> I want the stylii out this lot 141052857446
[20:18:06] <andypugh> Less that 100k seems like a very conservative target. No reason for it to be more than twice the price of a smaller one.
[20:19:04] <andypugh> What is it about them that you like?
[20:19:42] <archivist> I have one of those with no stylii
[20:19:59] <andypugh> M4?
[20:20:06] <archivist> nor the silly 1/2 C batteries either
[20:21:14] <eric_unterhausen> that thing looks like a home project, can't imagine there will be too many takers at 100k
[20:21:15] <andypugh> Do you want one of A-5000-7547 or A-5000-7549?
[20:21:55] <archivist> the diameter of the stylus hole seems to be 4.5 mm
[20:22:12] <archivist> it is an odd fitting
[20:22:33] <andypugh> Ah, not Renishaw then?
[20:23:07] <archivist> no, the competition from years ago
[20:24:18] <andypugh> Pity, Renishaw styli are actually surprisingly reasonably priced: http://www.renishawdirect.com/shop/search.aspx?ProductCat=Styli&Page=1&searchCriteria=ThreadMount_11,ClassName_15&tab=thread

[20:25:04] <Tom_itx> https://www.carbideprobes.com/
[20:25:05] <andypugh> I suggest you make an M4.5 to M4 adapter and just glue it in
[20:25:08] <Tom_itx> they may also have one
[20:26:46] <archivist> but the probe body was only ...£5 :)
[20:26:48] <andypugh> Ah, it looks like they didn't trust the Renishwa idea of just screwing probes in. (It seems ludicrous to me too)
[20:27:30] <andypugh> For £5 just carefully attack it with an M4 tap :-)
[20:28:36] <archivist> 4.5mm hole says it will miss the sides
[20:28:49] <CaptHindsight> just for fun I might make a glue gun using an older wide format inkjet, 5 x 10 feet should be silly enough
[20:29:42] <archivist> I may just use a bit of parallel bar as a cheap probe
[20:30:20] <CaptHindsight> but being a UV inkjet it's already capable of better prints than a glue gun, it just needs more Z-axis
[20:31:40] <andypugh> archivist: Good point, well made :-)
[20:32:37] <archivist> I just have to replace the cat 50 mount for a morse 2 mount (part made today)
[20:33:14] <andypugh> Renishaw do M5 and M5 mount too.
[20:34:03] <archivist> I dont want to disturb the mount if I can help it, would be better to make an adapter
[20:34:05] <andypugh> (I guess Renishaw are local to you too?
[20:34:37] <archivist> dunno, the prices are not local though :)
[20:35:40] <andypugh> Ah, no, they are in Wooton-under-edge, Glos. I thought they were in Renishaw..
[20:37:11] <archivist> I am near Burton
[20:44:22] <Nekosan> will linuxcnc run on ubuntu 12.04?
[20:50:14] <skunkworks> Nekosan: yes - but there pretty cutting edge..
[20:51:39] <andypugh> Yes, it runs and runs well. But not as precompiled packages, you will need to compile yourself, and on a patched kernel.
[20:53:05] <Nekosan> ok thats sounds hopefull...
[20:54:09] <Nekosan> anylinks to the patch?
[20:54:19] <andypugh> I am looking
[20:55:17] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?NewRTInstall
[20:55:27] <andypugh> I was looking at http://static.mah.priv.at/public/html/common/UnifiedBuild.html
[20:55:43] <skunkworks> Probably need both
[20:55:45] <andypugh> I am not sure which is better / easier / more stable
[20:56:06] <skunkworks> it is pretty painless after you do it once ;)
[20:56:40] <Nekosan> if i can build a 3d printer from scratch i should be able to muddle through this
[20:56:53] <andypugh> I have an SATA DOM within inches of my keyboard with a fully working Xenomai / Precise / LinuxCNC install on it.
[20:57:39] <Jymmm> andypugh: My shipping address is: Jymmm...
[20:57:47] <andypugh> (for what I do it is easier to swap the entire system disc for testing, the git archive is remote-mounted)
[21:09:59] <andypugh> Interesting, it seems that Renishaw have a Rugby pitch: https://maps.google.co.uk/maps?q=GL12+8JR&hl=en&ll=51.633668,-2.379205&spn=0.014171,0.024655&sll=51.79671,0.638411&sspn=1.807391,3.155823&t=h&hnear=Wotton-under-Edge+GL12+8JR,+United+Kingdom&z=16&layer=c&cbll=51.633626,-2.379285&panoid=gZRVjFW2x6tJogcbUT7_mA&cbp=12,0.5,,0,0
[21:14:28] <archivist> they are joint patent owners with RR for the three point probe
[21:25:14] <andypugh> Yes. I have not worked out why the inventor got to keep the patent, considering that he invented it on RR time. But there are other examples, Nakamura working for Nichia (LEDs) and MacPherson and Ford (the eponymous strut). http://en.wikipedia.org/wiki/Shuji_Nakamura http://en.wikipedia.org/wiki/McPherson_strut
[21:50:48] <lwizardl> hello
[22:01:54] <lwizardl> would the same process to build a CNC machine would to make a embroidery machine? i know parts would be different, but I was looking at the x/y axis
[22:29:24] <uw> yes
[22:33:59] <lwizardl> uw, so other then figuring out the thread section (maybe by retrofiting parts from a sewing machine) the same process could be used
[22:36:36] <uw> ??? it can be used for anything
[22:36:43] <uw> it's just a control
[22:36:46] <uw> via computer
[22:37:01] <uw> the computer moves this or that but some amount or another amount
[22:37:37] <uw> buy*
[22:37:43] <uw> by8
[22:38:22] <lwizardl> that was what I was thinking just wasn't sure if a diy type of setup could be done.
[22:38:49] <uw> i'm sure it has been done before
[22:38:56] <lwizardl> k
[22:39:13] <uw> linuxcnc (from what i've seen) is geared toward machinign typically
[22:39:18] <uw> like lathe or mill
[22:40:01] <uw> but it could absolutely be used to control things like sewing machines or auto turrets (like CIWS)
[22:40:38] <lwizardl> that was what I wanted to know :)
[22:41:32] <t12> lol
[22:41:32] <t12> a linuxcnc CIWS
