I have tried using Mach3 on 2 different motherboards (an Intel dual processor 500Mhz P3 and an IBM P3 1ghz). With both machines when starting a cut it will raise the Z-axis to it required height but will also move X & Y for no reason.
Below is the latest gcode I tried, the odd thing is it will start the cut and then go diagonal, curve around but ends up where it should. This is a simple square 1" across, I am trying to figure out HOW to make it cut out the exact size I need using cutter compensation.
