Just thought I'd share my benchtop mill powered by EMC.

http://distinctperspectives.com/coppermine/

It's a work in progress but I've got 3 axes operational - still some 
electronics to work on and a few goodies to machine for the mill and then 
it'll be 100%.

A question though - when I have the file loaded and touch off to the 
workpiece - it takes FOREVER to get back to ready to let me touch off the 
next axis.  What is this the result of?  The .ngc file is 
www.distinctperspectives.com/X3/LimitBases.ngc I know it is a lot of milling 
(it took a while to run) but it took longer to update after touching off 
than it did to parse the file at loadup.  I know I'm not running a top end 
system (it's a P3 650MHz w/384mb memory and onboard video that I picked off 
the curb one winter afternoon) but it had better latency test results 
(18000) than the newer MSI mobo with a Celeron and a gig and an ATI video 
card (I know the Celeron isn't the best for this kind of application but 
it's what I had to toss into the board which I got for a whopping $5 at a 
Hamfest because it had 2 bent pins on the BGA socket).  Anything I'm doing 
wrong or is it just the limitations of the memory and processor speed?

Thanks.
