New build, and new to building!
I have my three steppers working, But not smoothly. In fact they sound like they are driving on a cobbled street.
They components are pretty standard stuff, so hoping someone will be able to point me in the direction of a solution:-
Longs steppers 23HS 9442`s, Longs drivers DM542A (dippers 1 thro 4 off, 5 thro 8 on)
Standard Chinese 5 axis bob.
Mach3 P&P drives are Enabled. Dir.low active ticked and Step low active ticked.
Mach3 Motor tuning :- Steps 400 Vel. 3000 Acc. 600 - 0 step pulse & 0 dir pulse.

I hope it is something fundamental, but having lost two days experimenting. I really would appreciate some help if poss.
