Help on a couple of "niggles" with my machine.

Are you sure your motor steps per is correct and the machines moving exactly what you tell it to move.? What's the motor tuning at.? Vel & accel.

Have you checked for End float on the ballscrew.?

Only thing I can see that would cause this if no offset is applied could be those 2 things and I'd go for the Steps per and motor tuning first.!

Edit: No actually for what it takes I'd grab the screws for end float first but then I'd go for Steps per before anything else.!
