« on: March 19, 2010, 04:59:49 AM »
Hi all

I finally i got my system built . im working on a 5 axis cnc router. when i run my g codes mach shows all the axis moving fine on the diagnostic page. but when i run my motors i got only 3 motors spinning (the xy and z) my C B rotational axis are not moving. i have changed the pins and the other motor which was on the C and B was working ok , which means mach is not sending signals for the C and B . this is a sample copy of my g codes i set my (step per) for the rotation axis 4.4  200x8= 1600/360. im usin a DB25 brakoutboard
