[00:10:56] <Loetmichel> one who can read THAT handwriting HAS to be ;-)
[00:11:07] <Loetmichel> (doctors and handwriting...)
[00:11:15] <Jymmm> hahahahaha, too true
[00:11:52] <pfred1> did you write that with your mouse?
[00:12:00] <Jymmm> yes
[00:12:06] <pfred1> yeah I can't do that
[00:12:17] <Jymmm> it's kinda slow
[00:12:20] <pfred1> I'm not even very good with a stylus
[00:12:24] <Jymmm> you can't draw too quickly
[00:12:51] <Jymmm> just hit BACK button in the top left corner

[00:15:44] <pfred1> nope I suck even with a stylus

[00:16:37] <Jymmm> Big ass cue ball sized trackball
[00:16:55] <pfred1> lets see if I'm any better in inkscape than the gimp
[00:17:11] <Jymmm> Doubles as a "if you piss me off, I'm gonna throw this at you" trackball =)
[00:18:28] <pfred1> it's hard
[00:19:32] <Jymmm> pfred1: CorelDRAW lets you draw something and then interpret the shape, so I'm kinda used to it in a way.
[00:19:53] <pfred1> do you mean edit the line paths?
[00:20:48] <Jymmm> If I draw a VERY course shape with the mouse (like a triangle), it will figure out that I wanted a triangle and straighten the lines
[00:21:09] <Jymmm> or half moon, crescent, etc.
[00:21:58] <pfred1> oh
[00:22:18] <pfred1> I write like a 3 year old with computers

[00:30:46] <cradek> linuxcnc, and yes
[00:31:05] <Tecan> cradek the custom m codes arnt working on it
[00:31:20] <Tecan> the examples dir is sym linked to a broken link too
[00:31:32] <cradek> ok, can you give more details?
[00:31:55] <Tecan> i tried simple custom m codes in the nc_files folder and nothing is working
[00:32:17] <cradek> ok, more details please
[00:32:36] <Tecan> /usr/share/emc/ncfiles is empty
[00:32:47] <Tecan> non existant after updating to the new
[00:33:02] <cradek> examples -> /usr/share/linuxcnc/ncfiles
[00:33:21] <cradek> this is what my symlink looks like. perhaps your directory is not newly created?
[00:33:33] <cradek> the path you give is the old one.
[00:34:15] <Tecan> oh thats my problem, i renamed it
[00:34:20] <cradek> I just let it create a new ~/linuxcnc and it's fine
[00:34:21] <cradek> ok
[00:34:25] <cradek> ok what about the m code now?
[00:34:33] <Tecan> one sec i'll test :)
[00:35:54] <Tecan> still saying unknown m code used
[00:35:55] <cradek> I made a M100 script that just echoes a string, and it works
[00:36:09] <cradek> ok, tell me what all you did; you are doing something wrong.
[00:37:10] <Tecan> i copied a python script for graster M101 into the nc_files dir chmod it to +x and try to run it
[00:37:40] <cradek> what does graster do?

[00:39:29] <Tecan> unknown m code

http://www.linuxcnc.org/docview/devel/html/gui/gladevcp.html
[12:10:17] <witdraak> the run commands it talks of...where do you add them
[12:11:37] <witdraak> $ cd configs/sim <---
[12:11:44] <jthornton> those are terminal commands
[12:12:18] <witdraak> ok so i run linuxcnc then tipe those in terminal?
[12:12:27] <jthornton> and they seem to assume you know that and assume you are in the linuxcnc-dev directory of a git
[12:12:52] <jthornton> did you do a git checkout?

[12:13:53] <witdraak> im a fresh linux user so i have no linux background in terminal
[12:14:17] <jthornton> I assume if you have 2.5 installed you can just pick them from the configuration picker
[12:15:04] <jthornton> what a pia to have to close all those branches to find one

[12:15:41] <jthornton> what version do you have installed
[12:16:14] <witdraak> updated mine to 2.5 using that instructions
[12:17:08] <jthornton> then from the CNC menu pick LinuxCNC and when you finally get down to the sim branch you will find the gladevcp examples
[12:18:25] <witdraak> cd configs/sim im guessing that would be find in im guessing that would be in that configs file were your config for your cncmachine gets stored
[12:19:01] <witdraak> if true i don't have it on mine
[12:19:22] <jthornton> no, from the Ubuntu menu pick CNC > LinuxCNC
[12:19:42] <jthornton> err Applications > CNC > LinuxCNC
[12:19:49] <witdraak> top left of the screen?
[12:19:52] <witdraak> kk
[12:19:53] <jthornton> yep
[12:20:16] <jthornton> the instructions in the manual are very confusing about what to do :/
[12:21:02] <witdraak> i know got a pannel i managed to mock up in that gladeVCP but have no idea how to get them into my CNC program...
[12:21:36] <witdraak> were to save, how to link, ect.
[12:23:26] <jthornton> did you create your own gladevcp panel with glade and you want to add it to Axis?

[12:27:38] <witdraak> got up to 3.2 with the design but no idea how to load it and check it
[12:30:39] <witdraak> even if skipping 3.3 i dont know were to find the folder i need to save it to... "GLADEVCP= -u ../gladevcp/hitcounter.py ../gladevcp/manual-example.ui" (../ is very helpfull if you don't know your way around dos or kernal
[12:33:26] <witdraak> wish there was like a refrence sheet to what what kernal command do that looks like an asci spreadsheet. that most ppl have next to their computer
[12:34:27] <witdraak> ive learned that whatever i have to paste into kernal i have to add sudo before it and tipe password afterwards

phantoxe has quit []
[13:27:42] <JT-Shop> 5i25
[13:27:58] <JT-Shop> uses a parallel port cable
[13:28:01] <skunkworks> it actually has 2 'parallel ports' in effect.
[13:33:14] <Valen1> skunkworks: howdo you mean?
[13:34:28] <mozmck> anyone know if it's a pain doing 32-bit development on 64 bit linux?
[13:35:03] <skunkworks> it has a normal looking printer port out the back of the pci card - plus it has an internal header that you could hook another printer port pigtail to.
[13:36:25] <skunkworks> mozmck: I have 64 bit on my laptop. linuxcnc seem to run just fine in sim. (I did a lot of comp testing and compiling patches from the group on it) Other than that I don't know.
[13:36:51] <archivist> mozmck, gcc has a mode to force 32bit but I tried to use it the other day and got some errors and did not follow it up
[13:37:45] <archivist> was trying to build apt as 32bit on 64, its buggy on 64bit
[13:37:57] <mozmck> thanks. I'm looking at maybe upgrading to 64 bit linux, but I think I'll have to make 32-bit binaries of most things I do. So if it's a pain then I won't use 64 bit.
[13:38:07] <mozmck> archivist: -m32 ?
[13:38:14] <archivist> yup
[13:38:55] <archivist> but code does need dragging into the 64bit world some time soon :)
[13:38:58] <mozmck> interesting. I know you have to have 32 bit libs to run 32 bit programs, and you may need the 32 bit dev packages for development.
[13:40:11] <JT-Shop> Valen1: I don't think the 5i25 actually uses parallel port type inputs and outputs so to speak just the cables iirc
[13:40:36] <Valen1> interesting is that 5i25 the cheapest mesa board? I seem to recall they had a PP interface one that was cheaper (different application for this one)

[16:29:24] <jdhnc> I have a 34 and compumotor drive I'm going to use for Z
[16:30:27] <Connor> What's the torque rating on it ?
[16:30:44] <jdhnc> I don't remember offhand.
[16:30:58] <jdhnc> it's not really that high.
[16:31:16] <Connor> You planning on doing Ball screws or use stock screws ?
[16:31:37] <jdhnc> ball screws. I'm supposed to get one of the next batch of cncfusion prototype kits.
[16:31:51] <Connor> Ah. I'm using stock ATM.
[16:32:01] <Connor> I'll have to save up $$ for the ball screws.
[16:32:14] <jdhnc> I was going to, but sold a bunch of stuff so I freed up some cash for this.
[16:32:40] <jdhnc> I almost got enough crap out of my garage to actually be able to stand next to my g0704
[16:33:03] <Connor> I know have a little 7x10 mini lathe that was given to me.. So I can make the standoffs easier now. Not sure about turning ballscrews down with it.
[16:33:13] <Connor> know = now
[16:33:53] <jdhnc> I know where my 7x10 is, but I can't actually get to it :)
[16:33:56] <TekniQue> I found some ballscrew guy on ebay that will turn the end down to whatever diameter you like
[16:34:04] <TekniQue> and also cut them to length
[16:34:20] <TekniQue> username was linearmotionbearings
[16:34:36] <Poincare> sounds familiar....
[16:35:03] <Connor> I used them for my CNC router.
[16:35:08] <Connor> they're okay.
[16:35:42] <Poincare> must have bought some new equipment then, he didnt have that service when I ordered my screws
[16:36:03] <Connor> This was 2 years ago..
[16:36:39] <Connor> The pockets in the bearing blocks were a tad too deep. I ended up having to use shims to remove the slop.
[16:37:10] <TekniQue> linearmotionbearings2008 even
[16:37:18] <Connor> and someone had to make me longer spacers because the nuts rubbed up against the seal causing way too much friction.
[16:39:12] <jdhnc> the 5056 looks good. I might get a pair of those for x/y
[16:39:37] <jdhnc> the keling 23/23/34 kit looks good too though
[16:39:58] <Connor> http://www.automationtechnologiesinc.com/products-page/stepper-nema23-3-axis-kits
[16:40:05] <Connor> That's the one I got.
[16:41:38] <jdhnc> same price for 425/425/906
[16:42:01] <Connor> yea. I liked the idea of the 570's
[16:42:19] <Connor> and 570's is more than enough for direct drive with Ball screws.
[16:42:23] <Connor> for the Z even
[16:42:44] <Connor> should be fine for the stock screws too.

[17:11:19] <ReadError> they have a bigger one also, its like 129
[17:11:23] <alex4nder> I doubt it.
[17:11:23] <ReadError> and some smaller motors
[17:11:27] <alex4nder> get smaller motors
[17:11:29] <ReadError> 10A is plenty?
[17:12:07] <alex4nder> like, your taig is going to need like 45" of travel with those motors
[17:12:26] <alex4nder> ReadError: it's plenty for my setup
[17:12:30] <IchGuckLive> 48B 10A 3Axis is good
[17:12:40] <IchGuckLive> 48V
[17:12:54] <IchGuckLive> at 4.2A per motor
[17:13:07] <alex4nder> I think my motors will consume half that, max.
[17:13:40] <alex4nder> ReadError: I don't think any of their g540 stepper kits are a good match for the Taig
[17:13:42] <IchGuckLive> this brings in 3Nm thats plenty of tource
[17:14:01] <ReadError> alex4nder: thats the lowest
[17:14:14] <alex4nder> why aren't you just buying the parts?
[17:14:51] <ReadError> i can
[17:14:58] <ReadError> i thought it would be cheaper to combo them

[17:24:23] <ReadError> yea
[17:24:27] <ReadError> 2" knobs
[17:24:38] <ReadError> i just want to be able to do quick work if i need to
[17:24:45] <ReadError> so i want to retain that ability

[17:27:50] <Jymmm> skunkworks: and opto22 backplane plugs in directly to the mesa board?
[17:28:13] <ReadError> i guess if i had a pendant i wouldnt need to use kbows
[17:28:15] <ReadError> knobs
[17:28:22] <ReadError> would that function as a DRO ?
[17:28:28] <ReadError> since it can record the steps
[17:28:52] <alex4nder> yup
[17:28:56] <alex4nder> that's what I do
[17:28:57] <ReadError> ;o
[17:29:00] <ReadError> thats what i should do then
[17:29:09] <alex4nder> it'll make your setup simpler, and smaller
[17:29:13] <ReadError> well
[17:29:20] <ReadError> i want to get one of those boxes from homedepot

[17:29:34] <ReadError> they are like utility boxes
[17:29:39] <alex4nder> I mean the width of the taig
[17:29:49] <alex4nder> the standard motor couplers stick everything out on-axis
[17:30:16] <ReadError> got any vids of using the pendant?
[17:30:32] <alex4nder> no, but it's just a PS3 controller
[17:30:37] <ReadError> you can control it in 1 step increments? if so that would be super accurate
[17:30:39] <ReadError> ohhh
[17:30:47] <ReadError> i was thinkin about one of those hand held ones

[17:32:35] <alex4nder> BT probably works, but I don't trust it.
[17:32:39] <ReadError> and not centos or something
[17:32:51] <alex4nder> because RPMs are for sucks.
[17:32:56] <ReadError> eh
[17:32:59] <ReadError> yum is pretty solid
[17:33:07] <ReadError> if you have the right repos
[17:33:12] <alex4nder> yum is what happens when RedHat people get jealous of Debian people.

[17:41:56] <skunkworks> look at the same boards.. Black/red are outputs - whites are inputs.

[17:43:10] <skunkworks> (similar)
[17:43:36] <skunkworks> that plugs directly into the mesa board with a 50 pin cable.
[17:44:07] <skunkworks> the i/o from mesa can be either in or out - and then different modules are used in the opto22 board for in/out.
[17:44:07] <Jymmm> skunkworks: [ MESA ] <----[ 50 pin IDC Cable ]---> [Some PCB with screw terminals ??????????????]
[17:44:26] <Jymmm> really?
[17:44:45] <skunkworks> mesa <-> 50 pin cable <-> opto22 board with terminals.
[17:45:00] <Jymmm> what input modules?

Thetawaves [Thetawaves!~Thetawave@7-139-42-72.gci.net] has joined #linuxcnc
[21:24:40] <markvandenborre> I mean: I know how to run a Linux box well, and I love software freedom
[21:25:24] <markvandenborre> so as long as the fiddling is with software setup, I'm perfectly fine with that
[21:26:15] <markvandenborre> adding a usb device id to a c source file and recompiling stuff or creating a debian package from scratch shouldn't pose a problem either
[21:26:28] <djdelorie> usb and cnc don't get along well together
[21:26:49] <archivist> usb is baad for latency
[21:27:15] <markvandenborre> yeah, that was by way of speaking
[21:27:45] <markvandenborre> I was mostly saying: I feel perfectly comfortable fiddling with software
[21:28:01] <markvandenborre> and I'm quite stubborn getting stuff to run
[21:28:05] <SWPadnos> markvandenborre, when you say turn-key, are you talking about the physical hardware (the iron), the motor/drive hardware, the PC interface hardware, the PC hardware, or all of the above?
[21:28:28] <SWPadnos> or any subset - what the heck
[21:28:30] <markvandenborre> physical hardware, motor/drive hardware
[21:28:32] <archivist> so any router that is driven from the parallel port and uses mach3 will be trivial to move to linux
[21:28:56] <markvandenborre> any generic x86 computer part in the equation
[21:29:20] <SWPadnos> (note that my question was a free machine checklist for you :) )
[21:29:24] <markvandenborre> poses no problem at all to me obviously
[21:29:26] <djdelorie> there doesn't seem to be a "standard table", does there? They all seem to be custom in some way...
[21:29:33] <archivist> any 32bit x86 that passes the latency test
[21:29:55] <markvandenborre> archivist: I really don't worry at all about that part

[21:32:46] <djdelorie> maybe what we need is a common cnc table design, where the gcode for each part is available... like a reprap, but for cnc milling etc...
[21:33:14] <djdelorie> just plug in table size, press "run", and wait for your kit :-)
[21:33:14] <markvandenborre> gcode wouldn't take you very far would it?
[21:33:23] <archivist> djdelorie, I think I have seen something out there once upon a moon
[21:33:24] <markvandenborre> you'd need stl or dxf or something...
[21:33:49] <djdelorie> my point is, a *common design* to make a DIY table easier
[21:33:53] <markvandenborre> archivist: just out of curiousity...
[21:33:55] <archivist> but kit...not ready made
[21:33:58] <SWPadnos> markvandenborre, I think there are two main things you'll have to deal with: holding down the wood, and spindle/traverse speed.
[21:34:11] <djdelorie> the same files could be used for production
[21:34:42] <markvandenborre> you mentioned building new with framing type aluminium
[21:34:58] <archivist> I did see a parts list and sizes on one of the sites a year or two ago
[21:35:07] <markvandenborre> just out of curiosity (I really can't spend days on getting stuff to work)
[21:35:09] <SWPadnos> you need high spindle speeds to get the cutting speed needed for wood (presumably with small diameter mills), but you need fast motion to prevent burning with a high speed spindle
[21:35:25] <markvandenborre> good point
[21:36:02] <markvandenborre> that's stuff I hope to get covered in a preassembled design

[21:39:04] <markvandenborre> mostly straight lines (if diagnoal)

[21:39:30] <markvandenborre> 9mm of the 18
[21:39:34] <SWPadnos> ah, dado/rabbet slots
[21:40:10] <markvandenborre> a hat shape if you look at it from the side
[21:40:22] <markvandenborre> archivist: that looks like nice stuff
[21:40:48] <archivist> but its windaz
[21:41:31] <archivist> you could get the hardware and do the control yourself
[21:42:04] <markvandenborre> you mean write some software by snooping parport traffic, ...?
[21:42:37] <SWPadnos> no, Mach only uses the parallel port bu default (though they do have some USB add-ons).
[21:43:03] <SWPadnos> if these machines use the parallel port, then LinuxCNC can also drive them, since we can do everything Mach can do (and more)
[21:44:16] <markvandenborre> so the idea is that you throw gcode at the thing, right
[21:44:17] <markvandenborre> ?
[21:44:25] <SWPadnos> and it does look like they use the parallel port:
http://www.marchantdice.com/forumimages/SBOX.pdf
[21:44:59] <SWPadnos> well, they include some software that takes drawings of various kinds
[21:46:26] <SWPadnos> maybe you can get it for a few hundred less if you ask for no PC/Windows license/Mach license :)

[21:47:18] <SWPadnos> yep, that's the one I'm looking at :)
[21:47:29] <archivist> download the live cd and play
[21:47:38] <SWPadnos> note that it's a special "MachOS", based on XP Embedded.

[21:52:32] <markvandenborre> and other non-pc stuff
[21:52:49] <SWPadnos> the Hasse machine is smaller (their largest is smaller than the smaller Marchant Dice one))
[21:53:28] <SWPadnos> It looks like he spindle is a smaller router, which could possibly limit cutting capacity
[21:53:34] <SWPadnos> what thickness did you want to cut?
[21:53:55] <markvandenborre> 18mm mostly
[21:54:03] <markvandenborre> 18mm wood...
[21:54:04] <SWPadnos> ok, that's actually pretty thick
[21:54:14] <djdelorie> not to a woodworker :-)
[21:54:14] <markvandenborre> ah?
[21:54:17] <SWPadnos> if you want to do it in one pass, that is :)
[21:54:29] <markvandenborre> I don't care if it takes multiple passes
[21:54:36] <markvandenborre> as long as I don't have to do it myself
[21:54:37] <SWPadnos> well, it's thick to cut with a thin (1/4") mill, for instance

[23:00:29] <djdelorie> on mine, I had to debounce the switch or I got limit errors on *that* switch
[23:00:54] <joe9> looks like that is what is happening to me too.
[23:03:42] <joe9> djdelorie: is this the error: "emc/task/taskintf.cc 614: Error on axis 0, command number 136"
[23:03:46] <joe9> without debouncing?
[23:04:02] <djdelorie> no, a regular "joint on limit switch before home complete" error
[23:04:16] <joe9> after I disconnected the other 2 axes, it homes fine on the X axis, but gives out that error
[23:04:44] <joe9> "joint 0 on limit switch error" prints out before that message

[23:18:03] <skunkworks__> joe9: are sharing home and limit switches?
[23:18:09] <joe9> yes.
[23:18:24] <skunkworks__> so 1 pin does both homing and limits?
[23:18:26] <joe9> minimum limit = home switch.
[23:18:29] <joe9> yes.
[23:19:09] <skunkworks__> Ok. that is an issue. when the one axis is homing - the other axis sees the limit tripped.
[23:19:26] <joe9> there is home_ignore_limits to take care of that.
[23:19:27] <skunkworks__> there is a way around it but I am having trouble finding an example.
[23:19:39] <joe9> HOME_IGNORE_LIMITS = YES
[23:19:40] <skunkworks__> That is just for the one axis.
[23:20:09] <djdelorie> joe: are you mixing home/limit signals *across axes* ? I have one DB25 pin per axis for home/limit
[23:20:29] <skunkworks__> http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=38&id=9633&limit=6
[23:20:53] <skunkworks__> some reading
[23:21:43] <joe9> djdelorie: no, I am not.
[23:21:49] <joe9> i have 3 switches for 3 axes.
[23:21:53] <skunkworks__> oh
[23:22:01] <djdelorie> not switches, pins on the parallel port
[23:22:09] <joe9> i think I found my problem.
[23:22:19] <joe9> The reason was that I had to invert my X axes.
[23:22:35] <joe9> I had a +ve search and latch velocity, but min limit == home.
[23:22:44] <djdelorie> that would do it
[23:22:51] <skunkworks__> forget what I just said..
[23:23:02] <joe9> so, when it gets to 0 (min limit), cnc is confused as the +ve velocity is bringing it to minimum point.
[23:23:02] <JT-Shop> ok
[23:23:33] <joe9> http://www.mycncuk.com/forums/showthread.php/3276-EMC2-home-limit-switches-only-acting-as-limit
[23:23:58] <djdelorie> try this: away from all the limit switches, manually jog each axis and make sure that it's moving the way you want, and verify the homing directions
[23:25:45] <JT-Shop> joe9: if you use shared home and limit switch you have to make the home position a tiny bit away from the switch
[23:27:13] <joe9> jt-shop, yes i did that. my axis 0 from .ini file
http://codepad.org/ny86fvKq
[23:29:13] <asdfasd> there is something else - for some reason on my Z axis the homing sequence is inverse compared to X and Y, is it possible that your switch remain activated after homing?

[23:32:39] <JT-Shop> try HOME_OFFSET = 0.1
[23:35:03] <joe9> JT-Shop: ok, will do.
[23:36:24] <JT-Shop> or -0.1 what ever moves the axis off of the switch before the homing is finished
[23:36:57] <djdelorie> is HOME_OFFSET the location of the switch, or how far it backs off?
[23:37:23] <JT-Shop> how far it moves then that position is home
[23:37:32] <djdelorie> I thought that was HOME
[23:37:33] <JT-Shop> iirc
[23:37:46] <JT-Shop> that = what?
[23:38:11] <djdelorie> on my ini, HOME is the location it moves to after homing, and HOME_OFFSET is the position of the home switch itself
[23:38:25] <JT-Shop> yes that is correct
[23:38:56] <djdelorie> joe9's ini is the same way, but his never completes the homing sequence

[23:39:22] <djdelorie> mine was unreliable too, until I added debounce to the home switch
[23:39:37] <JT-Shop> he has an offset of 0 so he is sitting on the switch when the move completes so then he gets a limit error
[23:39:54] <djdelorie> he has HOME=10.0
[23:41:40] <JT-Shop> yep but home offset is 0
[23:41:52] <djdelorie> right, because he's using one switch for both home and limit
[23:42:11] * JT-Shop heads inside to start cooking the pizza
[23:42:14] <JT-Shop> good luck

[23:53:38] <JT-Shop> joe9: pizza crust is rising here is my X axis on my plasma which uses shared home and limit switches
http://codepad.org/EyTMhkRJ
[23:55:03] <JT-Shop> joe9: so during the homing move the axis moves 0.250" away from the switch otherwise when the homing move completes I would get a limit error
[23:57:05] <joe9> JT-Shop: quick question, why do you prefer a home in the middle and not to one of the sides?

[23:57:20] <JT-Shop> what do you mean?
[23:57:36] <joe9> isn't it easier to calculate if you have home closer to min limit or max limit?

[23:57:57] <joe9> then all the coordinates can be absolute positive values
[23:58:39] <JT-Shop> I never really set the limits up it seems LOL, my home is left rear top for X Y Z
[23:59:19] <JT-Shop> the point was you have to move off of the home/limit switch during the homing move
