Did this problem ever get resolved? I'm still getting the problem after downloading the 3.041 version today.
I'm trying to do a cut circle with center at x1.25, y1.25, diam 1.784, cutter diam 0.5, inside specified, climb cut specified, pitch angle 5 (although still have problem if this is set to zero).
I get a lead-in arc on the inside but then it keeps going and cuts another one on the outside.
Not so good, I ruined a nice piece of aluminum.
I've stated this before and I still strongly feel this way, you need to create a thorough test suite for these wizards and test them carefully before bundling them with Mach. Wizards are something you you need to be able to count on as being bulllet proof, but for me they've been my biggest source of crashes and ruined workpieces.
