I have not read all of the above but can you tell me what current setting
you have with the stepper drive?
depending on the position of SW1, SW2 and SW3 you set the current.
if the current is too low, it won't run fast or pull high loads,
it will just whine and think it's going somewhere (sounds like some
people I have shared a car trip with)
See what is said on the motor, as far as max current is specified.
then set the switches to that or maybe 1/3 more.
I have built about 5 machines that use steppers in the past.
They feel no pain if you give them a bit more current.
The drive says it's good from 20 to 50V DC. Obviously running near
50V will give you the best chance to drive a difficult load.
what voltage is supplied to the stepper drive?
(I have a few of these here at work and they have been reliable in my
use cases)
