[00:27:57] <Guest98500> is there anyway to update 2.3 emc with 2.4 from a thumgdrive? i need the dependicies

[02:08:28] <ichudov_> EMC 2.4.1 crashed today a few times. It happened when I loaded a lengthy program (1k lines) and was doing "touch off" from keyboard,
[02:08:58] <ichudov_> It reported a Pointer assertion
[02:09:10] <ichudov_> I only have 512 MB of RAM
[02:09:31] <ichudov_> and 800 MB of swap
[02:10:22] <foxtrot> would microstepping on the Z axis help with torque or hurt it
[02:54:08] <Dave911> JT: I can see why now! ;-)
[04:43:20] <L84Supper> http://chicago.craigslist.org/chc/bfs/1867161304.html hmm I could motorize the rotation for the head
[04:43:42] <L84Supper> anyone have experience with one of these?
[04:53:08] <KimK> spasticteapot: (Sorry I'm late on this, I was just now reading back) One way to cut 18ga copper and get a clean edge, with no deburring needed at all, is to use wire EDM. Same with any conductive material, any thickness.
[05:06:14] <elmo40> anyone know where I can get carriages for these rails?

[05:07:15] <spasticteapot> KimK: Oh, what I'd give for one of those machines...
[05:10:26] <elmo40> markusandroid: nice laser head. where did you get it from?
[05:11:29] <elmo40> KimK: or sandwich it between aluminum plate. it doesn't eliminate the burr but will drastically reduce it
[05:18:18] <elmo40> archivist: I am learning to be a tin whacker.
[05:19:00] <elmo40> how is the bottom lip made? I need to make a cylinder that holds water, out of brass or copper.
[06:37:21] <archivist> wired lip is a cheat on the models its a bit of wire soldered to the edge others are just the side overlapping enough to get the impression of the correct join

[11:15:39] <moopy> anyone have suggestions what is best way to multiplex position commands from axis?

[13:55:39] <cradek> what a slick idea
[13:59:34] <ichudov> Hi guys, good morning. My EMC 2.4.1 crashed a few times yesterday. I loaded a 800 actual line file (not counting comments and empty lines) with lots of circles. I was debugging a script to mill a cone shaped pocket. Anyway, EMC would sometimes crash with "Pointer assertion" if I load the program, and then home the axes with the program loaded. I believe this to be reproducible, though it did not happen every time. The PC has only 512 MB of memory and 800 MB
[13:59:36] <ichudov> of swap.
[14:00:18] <cradek> ichudov: can you put the full text of the error message on
http://pastebin.ca? I am not familiar with that error.
[14:00:48] <ichudov> I will try to reproduce it tonight and will save the full text. I have a website so I can publish it there.
[14:00:55] <cradek> ok, great
[14:01:01] <ichudov> Thanks cradek
[14:01:08] <cradek> maybe there will be surrounding clues that will help.
[14:01:22] <ichudov> Sure. I can also run it under GDB if necessary. I am a computer programmer
[14:01:53] <cradek> do you know which process is crashing?
[14:02:10] <ichudov> Axis itself exited when crash occurred, so I suppose that it is Axis that crashed
[14:02:58] <cradek> ok
[14:03:38] <ichudov> If I find a reliable way of reproducing, I will attach GDB to Axis.
[14:03:48] <ichudov> EMC has no limit on the number of lines, right?
[14:04:13] <cradek> only limited by what your computer can handle
[14:04:54] <cradek> AXIS does generate a preview of the whole program, so on some computers it gets slow to display it. that's usually the first limitation you see as programs get huge
[14:05:01] <cradek> but 800 lines of gcode is nothing
[14:05:47] <ichudov> OK, good to hear
[14:08:14] <cradek> that's only tens of kB of gcode. I know people often have gcode of one to several MB
[14:09:51] <skunkworks> have you run a memcheck on the computer? for shits and grins?
[14:12:34] <ichudov> This is a 8 year old POS PC. I actually bought a bunch of parts to make a new PC, with a 4 core CPU, 4 GB of RAM, etc. The "mini ITX" case will fit inside the control cabinet
[14:12:43] <ichudov> So I do not want to invest any more effort into this old PC
[14:13:18] <ichudov> But I think that memory is OK
[14:13:33] <cradek> memtest is a great idea when you're getting unusual crashes
[14:13:50] <ichudov> Yes, but this is a predictable crash. My xemacs is not crashing
[14:14:04] <cradek> ok
[14:41:40] <elmo401> this app says it can be used with Axis. hasn't it been superseded by something?
http://sourceforge.net/projects/vec2ngc/files/
[14:42:25] <cradek> elmo401: not sure - did you try it?
[14:43:56] <ichudov> elmo401: I would be interested to know if I can convert DXF to g code, so let us know what you find
[15:00:02] <elmo401> will try this weekend.
[15:14:20] <elmo401> another simple DXF to Gcode tool
http://sourceforge.net/projects/codeg/files/
[15:17:38] <ichudov> have you used any of them
[15:18:03] <L84Supper> http://chicago.craigslist.org/chc/bfs/1867161304.html interesting mill, I could motorize the spindles cutting angle
[15:19:23] <ichudov> It does look very interesting and the price is right. I think that CNC conversion will be a pain due to screws. It is a great manual machine however. For a similar money, you can buy a CNC knee mill with a bad control and do a PC retrofit.
[15:19:46] <ichudov> L84Supper: Let us know whay you think
[15:21:42] <elmo401> ichudov I 'plan' on using these apps. ;)
[15:21:56] <ichudov> elmo401: got it
[15:24:10] <skunkworks> One of the developers has a van norman.

[15:24:11] <skunkworks> http://jmkasunich.com/vannorman/VN_Home.htm
[15:26:01] <ichudov> L84Supper: I am in Chicago area. (stop by for a beer). I bought a local Bridgeport Interact 2 CNC mill with bad control for $500 plus $500 for 35 QC-30 toolholders. Selling off bad control paid for the mill. See
http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/
[15:26:11] <L84Supper> ichudov: I've been searching for cnc, but no real deals lately
[15:27:45] <L84Supper> heh .. beware Sugar Grove!
[15:28:40] <ichudov> Shameless plug, I will be selling my old 1 HP step pulley Bridgeport with DRO
[15:29:09] <ichudov> works great
[15:30:35] <ichudov> Just keep searching and you will find it. It is really great to start with good iron, that way all you need to do is buy extra electronics, connect the right wires with the right terminals, and write config files. Much easier than modifying some ancient hardware, adding ballscrews, dealing with issues etc
[15:31:18] <L84Supper> I usually design machines from the ground up
[15:33:09] <ichudov> Kind of like the 5bears guy
[15:34:21] <L84Supper> http://chicago.craigslist.org/chc/tls/1866221149.html
[15:35:05] <L84Supper> all the other mills lately around here have been $2k +
[15:37:10] <ichudov> Not bad too. I like Van Norman better. If you are really into looking for surplus, check out www.bidspotter.com -- look for IL listings. Many industrial cos are liquidating, lots of fund equipment. Also watch for upcoming auctions here:
http://www.machinetools.com/us/auctions
[15:37:27] <ichudov> I mean "fun equipment", not "funD equipment"
[15:40:17] <elmo401> any new Plasma wikis?
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Plasma
[15:40:41] <elmo401> ahh, I see some torch height control
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Torch_Height_Control
[15:43:49] <L84Supper> plasma, laser and inkjet could use a bit more flexibility from EMC
[15:44:01] <ichudov> OT, what Linux IRS software do you guys use
[15:44:07] <ichudov> IRC software
[15:44:12] <elmo401> IRS :P
[15:44:14] <ichudov> scary
[15:44:24] <elmo401> I use irssi
[15:44:31] <mozmck_work1> I use pidgin
[15:45:27] <pcw_home> chatzilla
[15:46:12] <ichudov> irssi looks interesting and has perl integration
[15:49:07] <cradek> this is cool to see:
