[00:35:59] <CaptHindsight> seb_kuzminsky: were you asking about 64b ARM boards? http://linuxgizmos.com/allwinner-reveals-new-octa-core-and-64-bit-quad-core-socs/ they should be dirt cheap in 6 months
[00:37:08] <CaptHindsight> sorry 12 months Q4, 2015
[10:52:23] <KGB-linuxcnc> 03Sebastian Kuzminsky 05seb/master/ftkalcevic-axis-estimate d5c05cf 06linuxcnc 10src/emc/usr_intf/axis/scripts/axis.py axis: improve program runtime estimation * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=d5c05cf
[10:54:08] <cradek> cool, I saw that too, thanks for doing the integration
[10:54:26] <seb_kuzminsky> sure :-)
[10:54:30] <seb_kuzminsky> how's your hand?
[10:54:48] <cradek> perfectly fine
[10:54:52] <seb_kuzminsky> oh good
[10:55:07] <cradek> it's mostly stuck back shut already
[10:55:12] <cradek> magic auto-repairing meat
[10:55:31] <seb_kuzminsky> reading that earlier made me think of that awful degloving picture that was part of the safety training at the university of colorado machine shop class
[10:55:53] <cradek> eek
[10:55:59] <cradek> I don't want to see that
[10:56:12] <seb_kuzminsky> it looked... uncomfortable
[10:56:31] <cradek> I had a ring on when I did this, too
[10:56:32] <cradek> stupid
[10:57:02] <cradek> it's a little engraving spindle, so I don't think about it, but it can sure still throw things and cut things
[11:14:19] <kwallace2> Hello, I have a .drd drill file I would like to get data from to make a drilling g-code file. I know nothing about .drd files. Any hints or links would be appreciated. Thanks.
[11:18:15] <archivist> should be something like a table of offsets from the reference corner with an id for the size drill, the id to dia may be in the same or a different file
[11:23:44] <kwallace2> Here is a peek at the file: http://wallacecompany.com/tmp/sample.drd
[11:24:02] <jepler> http://en.wikipedia.org/wiki/Excellon_format
[11:25:06] <jepler> M72 is Inch Measuring Mode
[11:25:19] <archivist> heh I was about to past the same link!
[11:25:33] <kwallace2> Excellent, Thank you.
[11:26:35] <Tom_itx> is that something eagle put out?
[11:26:43] <jepler> > Coordinates are measured either in inch or metric (millimeters). Inch coordinates are in six digits (00.0000) with increments as small as 0.0001 (1/10,000). Metric coordinates can be measured in microns (thousandths of a millimeter) in one of the following three ways:
[11:27:00] <jepler> so is it plausible that the first X coordinate os 00.9833 inches, and the last one 3.5683 inches?
[11:31:29] <kwallace2> It is likely this is an Eagle file, but I am not sure. The board is close to 5" x 6". My plan is to play with the file in Open Offc. Calc so I can pick out the holes I want. I'm need to make a bed of nails thingie.
[11:32:02] <kwallace2> I'm/I
[11:34:01] <Tom_itx> if you had access to the brd file eagle has a gcode user program to output the drill data
[11:35:05] <Tom_itx> as short as that file is, you could copy the numbers and write a short gcode file yourself
[11:36:16] <Tom_itx> you also need to know where X0 Y0 was in the brd file so you know how to orient the clad
[11:37:34] <kwallace2> I only posted the first bit of the file. I have files with .cmp, .sol, .drd, .fab, .plc, .pls, .stc, .sts
[12:31:01] <kwallace2> Open Offc. Calc must be one of the coolest programs around: http://wallacecompany.com/tmp/Screenshot_drd.png
[12:49:26] <kwallace2> As well as Linuxcnc: http://wallacecompany.com/tmp/Screenshot_drd_plot.png
[12:52:05] <kwallace2> Does anyone have a favorite pogo pin?
[18:08:56] <jepler> kwallace2: I know sparkfun has pogo pins, but I haven't used them. depending on your scale, you're also almost sure to be able to find them at better prices than sparkfun. https://www.sparkfun.com/products/9174
[18:18:15] <CaptHindsight> they come in lots of sizes, range of travels and shapes to the tips
[18:19:15] <CaptHindsight> kwallace2: they are ~10 cents each on ebay http://www.ebay.com/itm/100-Pieces-P75-LM2-Dia-1-02mm-100g-Spring-Test-Probe-Pogo-Pin-/231266494465
[19:19:38] <kwallace2> Thanks, jepler and CaptHindsight. I didn't realize these pins are meant to be used with matching sockets. The sockets will make life easier.
[19:20:48] <CaptHindsight> kwallace2: have you found sockets with the pitch you need?
[19:22:02] <kwallace2> Here is the socket that jepler linked: http://www.mouser.com/ds/2/181/S25-XX2-351647.pdf
[19:22:24] <kwallace2> So can be any spacing.
[19:22:56] <CaptHindsight> those are the pins sure
[19:23:51] <kwallace2> My under standing is that these pins go inside the sockets: http://www.mouser.com/ds/2/181/P25-XX23-350405.pdf
[19:24:17] <kwallace2> I ordered a different pin, but they are the same size.
[19:27:54] <kwallace2> The sockets have a ring shank that I can use in a light press fit hole to fix the pin.
[19:29:37] <kwallace2> I think all's I need to do is find sockets that are dirt cheap and I can get in hand when the pins get here.
[19:33:18] <CaptHindsight> kwallace2: if you can't find sockets with the proper pitch you can cast them into place using epoxy resin
[19:39:39] <kwallace2> My plan is to use two plates of acrylic: http://wallacecompany.com/tmp/Screenshot_pogo1.png with holes that match the holes from the board to be tested.
