As I have stated elsewhere, I just set every bit to 260ipm, 50ipm plunge, but change step/depth to what I used before that worked. Then I manually lower the feed/speed to begin and increase if all goes well to a comfort level. Again, that works just too well for me, so I do not know if I change or not to a sheet. I would still need to keep track of step/depth for each op - rough/finish/end/ball..........
The best answer to me would be for Rob to just allow me to pick the bit from the table and provide IN THE 3d CUT menu a way to change it for step/depth for EACH operation right on the page, by overiding defaults without having to redefine a bit each time
PLEASE
