Hi,
I ordered some of the 381oz stepper motors from Keling along with a G540.
The motor sheet says A+, A-, B+, and B- which I am assuming goes with the G540's A, /A, B, /B respectively. Their docs say that you can swap A and A/ if you don't get the correct direction which makes sense, but couldn't you also swap the A set and B set to do the same thing as long as the swap was A-B and A/-B/?
Second question has to do with the trim adjustment for motor smoothness? What exactly does this tweak? What does it sound like when adjusted and not adjusted properly?
Thanks,
Alan
