What's the peak rating for, if you never can get closer than 20% of it?
I might be worried that you might not be able to break static friction on
the table with 20 A. What is the leadscrew pitch, and is the screw directly
driven by the motor, or is there a belt reduction?

What horsepower and spindle taper does the machine have?
