Just got my machine together and tried a sample file. The X and Y axis seem fine but when the job is done, the Z axis is about a half inch above the workpiece and Mach 3 is indicating zero on the Z axis??? Obviously the job is screwed up as well, but only in the Z axis, X and Y seem to be fine. I've tried slowing the feed rate way down, but it doen't make any difference. My initial guess was that it's missing steps? I'm using Mach 3 with Gecko G320's and a PCI parallel card. My driver test seems ok, not quite 24,600 but pretty close and steady too. The Gecko's are not showing any faults so I assume the motors are keeping up with the drives?
Any thoughts would be welcome.
