It's often suggested to jog down to touch off. Maybe onto some paper or whatever. I think it's a bad idea because of the risk of chipping the flutes, and in the last 0.3mm it's difficult to gauge where you are. Jogging up is better, backlash notwithstanding. Use an accurate rod or the shank of an endmill, say 10mm Jog upwards while you gently try to roll the rod under the cutter As you near the crest of the rod you can see when you need to reduce the increment And if you overshoot, it's easy enough to lower and do it again Roland _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
