Hi Lee

Thanks for your reply. I think the issue is that the PC supplied by Sherline has built-in drives for the CNC lathe's motors. Something like this:

(although he has a lathe not a mill).

So I guess he really is tied to a Linux environment - unless he can develop g-code on Windows and copy it to Linux for running on the Lathe.
