Doug, hope you don't mind me asking, what
type of drivers are you using?

Detent torque of 42 frame motors is quite low
by comparison to smaller motors. Many people
mistake resonance problems for detent drag,
as they look and sound similar.

Now, I could be wrong, but it's possible your
system performance could be improved a lot
by using microstepping drivers.
