I need help with the “A’ axis, I have added a Stepper motor to the A axis to turn a glass cutter.

The Tangentail is active, I have a test circle that I used SheetCam to generate the g code. The problem is the

A axis stepper just spins until it gets to a set point then it starts to cut. I thing the a axis should go directly to

the set point not spin until the DRO stops at a set point. I am also not sure how to calibrate the a axis, and if there is a special post processor I should be using. Below is the g-code if this will help

What I am trying to do is cut stain glass. Have had success cutting straight lines using the jog control

Looking forward to any help you can give
