[11:33:07] <abetusk> cpresser_, wait, isn't 'F' the feed rate? So is the feed rate you were using 1400 mm / min or 600mm/ min?
[11:34:36] <roh> i used diamond coated endmills as well. but i do not remember how many passes i made.
[11:34:43] <roh> in fr4
[11:45:46] <Tom_itx> abetusk: also, endmills for FR4 are made different than regular endmills
[11:46:53] <abetusk> Like the one cpresser_ linked to? It looks kind of like chicken wire on the column?
[11:47:07] <Tom_itx> probably, i didn't click
[11:47:27] <Tom_itx> like a diamond knurl?
[11:47:30] <Tom_itx> probably so
[11:48:58] <abetusk> Google images look very similar to what cpresser_ linked, so yes?
[12:02:37] <IchGuckLive> hi all
[12:10:25] <IchGuckLive> Black rock city center camp opend today JEH Burningman is on the way for 2013c
[12:56:16] <IchGuckLive> im off BBQ nice weather in germany BY
[13:07:02] <jesseg> Das Vetter ist Gutten? :P
[15:37:34] <archivist> hmm tomorrow I shall cut a generated 29 tooth straight bevel gear for the first time. did the gcode today and tested with some air cutting
[15:45:11] <archivist> open question left how many passes/facets to get a "good enough" tooth profile or curve
[16:01:19] <AR_> about 12
[16:04:39] <gene78> Bit of advice guys. I've been buying my 1/2" thick micarta sheets to make pallets for holding PCB's to route them, from Hyland Hdwe in Hotlanta.
[16:06:12] <gene78> But the last sheet does not have marbled coating that faintly resembles formica. And I'm crushing it to beat the band with the table clamps.
[16:07:07] <gene78> The current PCB I am digging 5 thou deeper than ever before because its cold flowing.
[16:07:48] <gene78> So, where can I buy good solid micarta sheet, 2 sq foot or so at a time?
[16:08:00] <AR_> why does it need to be micarta
[16:08:50] <gene78> Insulation mostly since I'm using a probe contact to set z at 0.0000
[16:10:16] <gene78> This pocket was machined a week ago, and is now nearly 10 thou off, never been out from under the clamps.
[16:11:27] <gene78> Any other ideas for an insulated pallet?
[16:13:20] <AR_> delrin?
[16:13:56] <gene78> Walks around with humidity I hear
[16:14:42] <AR_> you could make an aluminum one and just insulate under it and under the clamps
[16:15:13] <AR_> i'm assuming you need the insulation because your machine is all metal
[16:15:41] <gene78> At any rate, I think one of these is all I'll do, its basically a test the idea piece, yes, all metal. a beefed up X1.
[16:16:45] <gene78> I thought of that, but the first step of the make is a fin on the bottom that forcably aligns it with the T slots.
[16:17:08] <AR_> so you are too lazy to indicate it in? :P
[16:18:25] <gene78> Probably, I thought of mapping it, but my Z isn't that precise for small motions that would be needed in the middle of a long cut.
[16:20:13] <gene78> This pallet is cut for this board, the next one will be 2-3x bigger both dirs, the biggest thing we can getout of the free eagle, about 4x4"
[16:21:45] <gene78> So this pallet, now that I know its junk, goes out with the trash next Wednesday morning.
[16:40:13] <JT-Shop> anyone want to test my G code generator for tapped holes on a mill?
[16:43:58] <DJ9DJ> gn8
[16:57:42] <AR_> gene78, you could just machine it flat again
[16:57:47] <AR_> right before doing a board
[20:09:45] <cpresser_> abetusk: 600 was just a guess. i looked it up in an old gcode file. i did run it with 1400mm/min
[22:41:20] <tjtr33> hello, does Charles Steinkuehler come on the irc? ( The gent who did the 3D printing at the WIchita-ta Fest )
[22:46:56] <tjtr33> my real question is how could Hal data be posted to a server? ( sans linuxcnc , as in "halrun -I -f myhalfile.hal")
[22:46:57] <tjtr33> I am not at all versed in networking
[22:47:43] <tjtr33> my intention would be to have browser based Hal interfaces without NML et al
[23:07:49] <tjtr33> ok, so CGI is for "passing information between client (browser) and server, " well thats a start
[23:25:40] <tjtr33> there's always surprises in the source
[23:25:41] <tjtr33> has anyone played with 'halgui.py' ? ( .../yourRip/src/hal/utils/halgui.py )
[23:45:11] <tjtr33> looks like rtapi does the actual getp gets setp sets
