There are companies that regrind worn ball screws then stuff them with
oversized balls, at much lower cost than a whole new ballscrew. ISTR reading
some claims of making a rolled screw as precise as a new ground one since
they're precision grinding the old rolled surface.
Whether or not it's cos

Look at Tompson in the US for small ball screws. They have three styles of
nuts. They are expensive because they are spec'd to have micrometers of
error.I was going to buy from Tompson but ordered a Chinese 16mm screw
and found that within my ability to measure the Chinese screw was perfect.

Gene,
I'm not familiar w/ the 3phase steppers, but usually stepper drivers have
dip switches or a dial to change the current to the motor. You'd want to
flip them in such a way to select a lower current, which in turn would
provide lower torque. This 3 phase stepper is probably an odd ball

I suspect that all of these Chinese drivers are actually the same. Likely
they are all Leadshine clones. The ones I buy from "Stepper Online" are
leadshine clones.
Go to the leadshine web site and fine the product you have. It may have a
