What is an M910 code on a Mazak 10MS lathe with a T32-3 control? I am doing a simple little stepbore and the lathe stops on the second internal chamfer and won't budge. No error code and it runs perfect in graphics. My 8N Mazak lathe runs the same program perfect. Other guys in the shop can't find any program problems. Have tried with cutter comp., without cutter comp.--this is driving me up the wall. Any ideas short of a small explosive device taped to control?
