Re: odd setup

Well, for coordinated motion I think matched motors would be nice for
at least x and y. Depending on how you do Z axis it could use more
power than x and y and use a different pulley ratio. So a different
motor may be appropriate for Z. If you really wanted to, x and y
could be different but due to slightly different rotor inertias I
would expect things like circles to have slightly different machine
marks at the least.

A axis or rotary, could be anything, stepper or servo.

Programs like mach2 do not care how you mix and match things.
