Hello Jan
It would be helpful to have a sketch. Your start point and the first values in the cycle don’t match up. But maybe I’ve got my wires crossed somewhere. Do you mean the cutter coat writing cutter form 2/3?
If you do, it can be the problem. The coat has to be 7 in case of planar cut-in, it should work with 2 D-numbers.
Greetings
Michael
