We are going to have an area for CNC demos at Cabin fever. I will be doing a conversion of an X2 mill at the show, which will be raffled off on Sunday afternoon. It will use the screws from KDNtool and servos and control box from IMserv.
We will have a couple CNC seminars, one on EMC, and I know at least a couple guys are bringing small machines.
I will have ac neat little PC104 running Mach under embededXP with a Smoothstepper.
Cabin Fever is in York PA, see http://cabinfeverexpo.com/
