Changing the gear ratio

I am thinking about buying the crossfire and was wondering if anyone knows if you can change the gear ratio for each axis
I would like to customize one axes to move around a cylinder and need to know that I can change the amount each step the stepper motor equals.
A screen shot would also be great
Thanks

Gear ratio is the lead screw. You can change lead screw ratio’s and yes then you have to make adjustments to the settings as well.

Your request is also somewhat perplexing and confusing customizing an axis to move around a cylinder. That is more of setting an inhibited zone.

Steps per revolution is adjustable in Mach 3. The drives micro stepping setting is also adjustable but on the drives only.
