Hello, I just installed MACH 3Mill to my computer (celeron 2,4G, 1GRam) and I calibrate the strokes of the mill machine. When I try to move one axis, no matter which one I have some intreruption's in movement, very shorts, is about 50ms or near. I don't know from where they are coming and if is any method to can eliminate them. I tested the drives, and motors and they are OK, they are coming form LPT port.
