[00:44:03] <KimK_laptop> jepler: Re your testing on basswood being too slow, some lasers use an oxygen assist, makes (some) workpieces burn faster and keeps combustion byproducts off the lens.
[00:44:06] <KimK_laptop> For the sake of argument, if you could get, say, double the speed would that be worth anything, or would that still be too slow (underpowered laser)? Just curious.
[07:21:05] <jepler> KimK_laptop: probably just putting a fan in wouldn't hurt.
[07:21:57] <jepler> KimK_laptop: I think it would be silly to spend money improving this joke of a machine. 
[07:24:03] <jepler> .. it can do a few very minimal things but the utterly un-fixable working area of 36x36mm means it's not worth fixing other things like the limited laser power
[09:42:27] <seb_kuzminsky> jepler: how hard would it be to mount the laser on your zenbot
[09:42:29] <seb_kuzminsky> ?
[09:46:58] <cradek> the laser is modular and round so the mechanical part would be very simple
[09:47:18] <cradek> I mean it's a cylinder with a lens on one end and wires sticking out the other end
[09:47:45] <cradek> but I think zenbot might be at least a bit cannibalized right now
[09:47:46] <jepler> seb_kuzminsky: If I were going to put a laser on another CNC I'd also use a better laser
[09:51:07] <seb_kuzminsky> makes sense
[09:51:56] <seb_kuzminsky> people at the hackspace keep talking about putting a 3d-printer extruder on the 5'x9' shopbot
[09:52:04] <seb_kuzminsky> because that's the kind of thing hackspace people like to talk about
[09:52:19] <jepler> you wouldn't live long enough for a 5'x9' print to finish
[09:52:19] <cradek> is that practial in any way?
[09:53:12] <archivist> should be fast enough with a 1 sqin nozzle
[09:53:55] <seb_kuzminsky> heh
[09:55:19] <archivist> 1 sqft for the fastest speed, /me starts a blobbit kickstarter
[09:57:08] <seb_kuzminsky> use continuous-flow expanding insulating foam
[10:04:14] <CaptHindsight> they don't the budget for either but an inkjet array or a projector/s over a pool of photopolymer
[10:21:24] <jepler> "they don't the budget"
[10:21:24] <jepler> ?
[10:22:43] <jepler> I sort of want a photopolymer + dlp 3d printer but haven't looked too seriously at the options.
[10:26:10] <jepler> archivist: pictures of my little laser toy freed of google and javascript http://emergent.unpythonic.net/01444658636 , excess words added
[10:35:21] <cradek> ... so I took the engine out for a look. This might seem a little extreme at the side of the road in foreign lands, ...
[10:35:35] <cradek> /andypugh
[10:48:20] <seb_kuzminsky> andys trip report was awesome and hilarious, though i'm not sure if it felt that way to him at the time
[10:54:52] <archivist> jepler, I noticed the other day the triangles on the base line, is actually a curved base line
[11:05:50] <jepler> archivist: I think the paper itself was not lying completely flat. It is a pretty straight line in real life.
[11:05:59] <jepler> .. not lying flat when the photo was taken
[11:06:21] <archivist> ok
[11:18:40] <skunkworks> zlog
[22:00:43] <jepler> after a whole evening of time, I now have a useless modbus slave running in my arduino
[22:01:09] <jepler> (it just has one register to read, which blindly counts all the time)
[22:05:48] <jepler> and I can't even figure out enough classicladder to make the value appear on a pin
[22:06:20] <jepler> just in "%W0" in Watch Window
[22:36:01] <skunksleep> Looks like the masuura has 5v encoders.
