I am wondering if someone knows how to define Mach3 settings for a SO3 lookalike (not a Carbide 3D kit), fitted with HDZ z axis, Nema 23 30kgf motors, DMA860h drivers and a Nevex NX-800 ethernet breakout box. I am actually trying to do motor tuning using Mach3 and could mimic the procedures I found on youtube for the X and Y axises. But the Z axis procedure, using a dial, is not producing any consistent result. Using steps per mm as mentioned for grbl makes the Z axis crazy. Thank you!
