I have a Crusader M Controller on a 3 axis cnc mill. When I program the Frame milling sequence with all the varibles needed in the program, everytime the Z feeds down to repeat the same pattern, the tool will move over in the X or Y at the same time. I have also had the machine go into a Z feed down when it is not called out in the program. I have had these issues with or without cutter comp, in rectangle patterns and in arc patterns. Any idea why? I have not yet completely ruled out that the operator may just be an idiot, but I've spent hours trying to sort it out and have ran out of ideas.

Thanks,

Kevin
