Brian, from LVL1 here.  FYI, our CNC is running on an 750Mhz P4? Sony laptop that has a parallel port.  It runs EMC under an older version of ubuntu and works like a champ.  You really do not need a very fast machine, but you do need a parallel port.  If I recall I had to run some programs to figure out some parameters for the real-time kernal that EMC uses (http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test).  Also, when emc is running I cannot have a USB drive plugged in or EMC will skip steps.  I do recommend EMC if you want to go that route.  If you need any help, drop me a line.

I have an old (2004 vintage 64 bit) compaq laptop running XP that I'm willing to donate to run Mach 3 but I don't think it has parallel ports so it might be useless. I'm also having trouble booting it ...more

I've used both programs with my cnc. EMC works but was slow and I
could never get the configuration exactly right. Might try it again
since I'm using a different controller now.

Oh, and if using a commercial router instead of a spindle motor I
highly recommend a separate speed control for the router. Different
materials work better at different speeds. I think I paid $60 ...more

Dave Hempy <DHe...@ket.org> May 08 01:47PM  

Thanks for the offer, but we do need a parallel port. Laptops are also discouraged, due to a variety of hardware and power optimization features that laptops tend to have. It seems people have the ...more

Thanks for the feedback, Michael.

I'd love to when fully functional again. Currently my space is 1 butt
only in my garage.
 
 
We're working on a much larger project with a lot more space but are
funding hungry at the moment. ...more

I can donate:
A freshly installed windows XP activated box with at least a gig of ram and 1 adequate hard drive.
I need to get some of these old boxes out of here. My office should be on ...more

Dave Hempy <DHe...@ket.org> May 08 02:43PM  

That sounds *perfect*, Chris. Thanks for the offer! I can't make it down on weeknights very often, but if you could set it on the router table or put a note on it, we'll run with it next time we're ...more

It does have a drive in it, and I have the info about this touch screen PC, because I worked with the person who donated it. I also have the touch screen drivers, and need to follow up with the person ...more

It's a single core athlon 1.5ghz in a white mid tower case.
60 gig hard drive
480 mb ram (512 minus the on board video memory, i think)
Sorry to say I didn't have a cd rom drive to spare.

Dave Hempy <DHe...@ket.org> May 08 06:00PM  

That's cool. Is that machine intended for the router? I think the sticker was for Win2K, but maybe someone can check and report back Wed night. Anyone have an ISO for that?
 
I don't care which ...more

jho...@jdubb.net May 08 02:23PM -0400  

Yes, that machine is specifically for the CNC. I don't care which PC either, but the touch screen might be better because of issues that could happen with mice and keyboards on a CNC. ...more
