I have my 203's working on 2 axis but it does something very strange on the Z. It will ocilate (sp?) back and forth, and when press the jog button for CW it jumps a little then goes, when I jog it CCW it still goes CW, but in a jumpy fashion. If i tap the jog button, it will jump forward then reverse itself. Is this a MACH setup issue or a wiring issue? I have it wired in series.
Thanks - Bryan
