Looks huge for a plasma table.

Item 10-1834 has an encoder. I wonder if it is a 50 quadrature or if
it is a 200 or whatever....

I assume that the motor voltage for servos is the limit for the
motor ? unlike steppers where we volt the heck out of them ?

Seems like there is a lot to learn on servos. Guess I'm back to
where I ws when I was intorduced to steppers.
