Help setting up 4th axis

Hi,

I have a sherline rotary table as a 4th axis on my taig. But how do I set this up in mach so that I can rotate it in degrees?

I do know the following:

the rotary table has a worm gear that need 72 revolutions to make the table turn one revolution.

The motor is driven by a gecko 540 and has 200 steps per revolution and 10 microsteps per step.

Can someone tell me what I need to enter in motortuning in mach for this and how to setup mach in degrees for the a-axis?

thanks, Daan
