Hi, Brian
I try ed the Rev. Arc as you stated, Just big circles with that.
It's not just the Arc's, First straight line are cutting deepest cut's first.
My Turn Options are X mode Diameter "checked" and Rev. Arc's in Front "checked", Had to edit code missing G01 at bottom of code.
I'll post screen shot with courser cut's smaller DXF and Tap Files.
Thanks, Chip
OK, Thanks
