Tom,

Using analog outputs to servo drives. In Kmotion my z axis works
properly. Positive is down Negative is up. Went through all the
tuning steps and all worked well.

Created my C program and got Mach3 working. All work well except
the Z axis in reversed. X & Y are fine and match the Kmotion
behavior. In mach3 the Z behaves the reverse of how it did in
Kmotion. Any thoughts.

I realize that I could reverse the direction in Kmotion and it would
probably work correctly in Mach3. But shouldn't they match?


Thanks,


Barry Barbour

Hi Barry

Do you mean to say KMotionCNC works properly?

Does your table move up and down or the spindle?

Normally the tool moving up relative to the Table is +Z.

Does KMotionCNC have a negative counts/in specified in the Too Setup | Trajectory Planner | Axis Prameters?

Regards

TK
