Probably something i have not set right but...
When I load code, it runs through each line on screen, then when i press my "set origin" button it re-runs the whole lot again.
This can take some time on a full sheet, am i doing something odd or is this normal behaviour for Mach3??
BTW my set origin button (i think) copies the current position to a G54, then zero's the DROs then regens the toolpath display, basically makes wherever i stick the torch my zero point.
