Ok, have been using Mach 3 on old computer and had minor issues. Upgraded to new computer and better board(pokeys 57 cnc board). Now have issue with every program. It either will not load and I have to cancel then reset then regen tool path. The sometimes machine moves and cuts one thing and just stops and I cant reset program and spindle keeps going. It also will cut and then on z retract just stops and shuts spindle off. Any input would help as I am about to stop using this and upgrade to Centroid. I am in the middle of a project that in the past has taken me 3 hours to cut 6 pieces to got 2 cut because of the program acting up.
