Hi
My scenario is as follows. I'm trying to machine some parts on 20mm perspex, using a 3.2mm end mill and have added an extra 1.6 mm for CutWidth (so 3.2+1.6=4.8). When it completes the final depth and retracts, the tool rubs onto the side of the perspex. Without going into the details of my poorly designed CNC machine, it has caused my Dremel took to smoke up, because the Dremel tool lifts the entire table up with the perspex on it and the whole thing ends up getting stuck. This problem won't be an issue in the one I'm planning to build. But in the meantime I need to use this CNC to make parts for the new one.
So short story out of the way, how do I go about generating safer paths so that the tool moves a bit into the middle of the groove that was set by CutWidth, before retracting? That way the end mill is not touching anything on the side. Can I simply draw a line and tell it to move along it?
Thanks,
Nghia
