i am following ya. when i input the 20,000 into my motor tuning, the DRO moves , but not correct. for instance, if i move x-axis 3 inches ,the DRO will read 20. As if the units were in mm instead of inches. Double checked that. The only way for me to get the DRO to read somewhat correct is to calibrate and allow it to change the motor setting to its new value.
