I was thinking about this...it would be nice to get the direct-coupling of a stepper for the z axis, since that axis typically has the least torque requirement, and I'd like to keep the design of that axis simple. But for my x and y axes, I'd like to use servos.
Is it possible to mix servos and steppers this way? I'm thinking that I would just buy the appropriate driver module for each motor -- but what about the power supply? Can I get into trouble by attempting this?
Thanks,
Chris
