Torch not stopping before end of cut

I am trying to fix a problem created when the plasma torch does not turn off before it crosses a previous cut. When this happens, the arc wanders and takes a nasty bite out of my work. I have tried using cutting rules to resolve it but don't seem to be making much progress. Sheetcam is inserting a M...

Parts Undersized

I have a problem with plasma cut parts being undersized. I believe it may be due to the offset I am selecting in Sheetcam. I normally select inside offset so the lead in and lead out occurs on the scrap material and not the part. Today I cut a sprocket from 1/4" mild steel that also contained a...

Touch off prior to each pierce

I recently installed Sheetcam to generate code for Mach3 and plasma. I selected the Mach3 with scribber post processor. The gcode generated is perfect except it touches off prior to the first pierce only. Is there a way to edit this post processor to allow touch off prior to each pierce or is there ...
