I coded g0 z15.000 so I could get a good look and did this several times. 039.4 stopped and 149.4 running and then stopped returns to 039.4. So that looked good but then I coded g0 z0.0000 and it moved 0.001 an stopped on the DRO and I got 061.4 MV, , Stop it an re code it and it would run, It doesn't change direction with out using the code twice
