I recently upgraded to a direct drive z slider, everything was great on initial installation. However, when I made the calibration changes on tbdcnc.com the z axis reversed its direction. I tried changing $102 and $3 back to what they were before, but its still reversed. I dont know how it happened.
I need to swap some wires to reverse the polarity to get it to move in the right direction, but I am having trouble finding a diagram so I am not sure which 2 wires to swap.
can anyone help me out?
