even stronger ones now.
I have never tested the torque, but the original stepper generator
manufacturer sent me a junk chip and the X axis ran away on the first
move and crushed a metal oil line before it stalled; which may have
saved the ballscrew.
Needles to say, I have been using another step generator provider.
EMC2 will be the third.
Thanks Guys
