Thanks for the advice - I did order the antek, so I can compare it to the
switcher side-by-side. My main problem is actually with RF interference
from the stepper driver feeding back into the controller and confusing it.
A couple of caps on the step and direction lines cleaned it up but that's a

I've been using a 48V switcher (Mean Well) with a 10A stepper driver, but
I'm not happy with the stepper driver so I want to go to a Gecko which is
only 7A, so I am hoping to compensate by going up to a ~60V power supply,
