[00:56:54] <mrdata> sure, claim it is the size of a burrito
[01:17:05] <z64555> that sounds like a depraved comment. lol
[08:16:09] <SpeedEvil> http://uk.rs-online.com/web/p/products/8418462/?grossPrice=Y&cm_mmc=UK-GDN-_-google-_-1_UK_GDN_Rmkt_RS_AB-_-Rmkt_RS_Cart_AB&mkwid=c_dc|pcrid|96726039186|pkw||pmt||prd|&gclid=CLjVueHjltACFc8y0wodGHMCaA
[09:29:22] <rue_house> wow, the more I play with bCNC the more I'm impressed
[09:33:00] <Tom_L> did jester get that installed?
[09:33:06] <rue_house> no
[09:33:13] <rue_house> we spent the night redeisgning parts
[09:33:28] <rue_house> Tom_L, load and play with 'bCNC'!
[09:33:52] <Tom_L> what platform?
[09:33:58] <rue_house> python
[09:34:00] <rue_house> (any)
[09:34:35] <rue_house> only a little hastle finding pyserial for windows, otherwise ... impresive
[09:35:35] <Tom_L> made for circuit boards?
[09:35:40] <rue_house> no
[09:35:49] <rue_house> its.... impressive
[09:36:05] <rue_house> I got it for the windows machine to send nc files to the machine
[09:36:24] <rue_house> but realized I can edit the nc file in it before it sends
[09:36:45] <rue_house> then I noticed its got a cad tab
[09:37:18] <rue_house> I just tried loading a unfriendly dxf and it did quite well at letting me generate nc for cutting things out and pocketing
[09:38:16] <Tom_L> looks promising for a 2.5d cad cam
[09:38:39] <rue_house> I was gonna write a program for sending the nc files to grbl, but this will do
[09:38:58] <rue_house> "grbl-control" is HORRID
[09:39:18] <rue_house> 3 seconds minimum latency
[09:41:36] <rue_house> it will let you disable sections of code
[09:42:16] <rue_house> it takes in dxf as sudo-nc files and lets you make nc commands from them
[09:43:04] <rue_house> it would complete an emc install
[09:46:51] <Tom_L> nice
[09:46:55] <Tom_L> off to play now...
[09:47:17] <rue_house> yea, I got 8.5 hours of play to deal with myself
[09:47:38] <Tom_L> slow here
[09:47:48] <Tom_L> prolly back by noon
[09:49:33] <JT-Shop> I wonder why he is using tkinter?
[19:43:42] <gmct> Hey, I was wondering if a Rumba board would be able to be used in applications outside of 3D printers.
[19:44:08] <gmct> I'm looking to build a Rubik's cube solving robot and the rumba board seems like the logical choice since it has just enough built-in ports for the robot.
[19:44:44] <gmct> But I'd hate to drop all that money just to find out it's only good for 3d printers.
[20:16:45] <rue_house> JT-Shop, it all seems to be tkinter with python
[20:16:57] <rue_house> sorry, I missed in you the list
[21:36:55] <justanotheruser> Someone wanna recommend me a motor that has around 50-100lbft of torque but doesn't necessarily have much speed?
[21:45:40] <Tom_L> gear reduction
[21:52:46] <justanotheruser> Was thinknig of getting a servo with a 50:1 reduction, but the gearbox is more expensive than the servo motor in the cases I've seen
[21:53:11] <justanotheruser> where can I get the best bang for my buck in terms of planetary gearboxes for nema23
[22:14:00] <SpeedEvil> what speed
[22:34:12] <justanotheruser> around 50 rpm
[22:34:30] <justanotheruser> less if needbe
[22:39:36] <SpeedEvil> 100lbf = 500Nf = 150Nm. 150Nm * 1 revs per second = about 150W.
[22:39:53] <justanotheruser> mhm
