Re: USB 2.0 CNC control and high speed stepper driver

Hi all,

If anybody has more questions post of mail them, I will contact them
on monday and will try to get some answers. The high torque at high
speed is mostly a voltage thing (I think), I remember they use the
Powermax steppers and used 160 V at 12 A, to make sure they wouldn't
overheat they used heatsinks and fans direct on the steppers.
