for some reason I punch in numbers to sheetcam jet cutting and want to overcut my part. but it does not seem to want to go past the ending of the cut! can someone explain overcut to me?
First, let’s be sure we’re talking about Overcut in the Jet Operation window, right?
A couple reasons come to mind…
- a path rule (before end) can prevent cutting beyond end of contour (shape). If this is in play, then the XY motion will continue to the overcut distance while cutting stops short of it.
- an open shape does not apply overcut. You may have an open shape and are not expecting it to be open. turn on menu Mode / ‘Show path ends’ and turn off Mode / ‘Show segment ends’. If you see two white dots on the shape in question, then its an open shape, that explains no overcut.
- a negative overcut value is actually an undercut (short of full shape length).
If none of this applies or explains it, please upload your job, pp, and gcode files; we’ll have a look.
