Hi Jim, This machine should make a fine conversion to emc.
Relevant material is on the emc wiki. Just go to the 'Page Index' and look at the different listings under Mazak. also: http://webpages.charter.net/bengvall/emc/emcconversion.html Your most difficult problem may be to decide what wiring to keep and what to tear out. ;-) HTH Dave On Oct 1, 2007, at 8:53 AM, Jim Coleman wrote: > Hello everyone on the emc users list!
