At least the brushes appear to be easily externally accessible - so easy to change I would guess.One of their downsides is that I think brushed DC servos are used - so they will have a finite life, I will swallow that
Do those motors have integral brakes? If not, you might need to add one on the Z axis if you're going to run a big fat (end hence heavy
) spindle - servos don't have the stiffness that steppers have when the power's off, and depending on gearing etc., you might get a slowly drooping spindle when you switch off.
