I have saved the yacht demo file from Velectric cut 3D, and have used it to cut several pieces, so it is a proven file , and no issues with the PP.
Today I opened the roughing file and now, out of the blue, it has about 50 concentric circles in the tool path.
The finishing file does not have them.
WHat happened?
Where did the G2 commands come from in the roughing file?
did I set some option unknowingly?
