Thanks for your replies.

Did the G00 A1 test. With the Steps Per in Motor Tuning set at 1600, the A-Axis turns a full 360. If the Steps Per is set to less than 1600, the revolution is less than 360. I just experimented to arrive at the 1600.

When I do the math for Steps Per, I get 13.333. That is 200 x 8 microsteps x 3 (I am using a 15-tooth .2 XL pulley on both the motor and the a-axis) = 4800 divided by 360 = 13.333. The motor will virtually not respond at this setting. It is invisible on the Motor Tuning graph. That is why I experimented to get up to the 1600 Steps Per.

By the way, the a-axis responds the same whether 'A-Axis is Angular' is checked or un-checked. Which leads me to believe this isn't the right setting to make the a-axis rotary, but then where is the correct place to make this change?
