First the 01 is an invalid word. to name it it must use the o1 word not a ZERO 1

You are calling to USE tool #3  M6T3

BUT you are calling the COMP to use tool#33  D33.

Also there is really no reason to comp each and every move down through the helix Just comp it at the beginning and remove at the end . IF you are doing it to get a smooth transition then just program a small circle coming out of the circle end move and back into the beginning move. During that small transition move lower the Z to the next cut step. It makes it much faster and just as smooth running/cutting

(;-) TP

Hej,

Thanks a lot, I removed D33 and works fine.

Maybe you know how to do this in Solid Cam
