Hi Guys, I am stuck trying to get my TB 6560 controller board working with my 3x Nema 23's

When starting up the TB6560 Without the computer turned on, they were nice, quiet and ready to go.

But when powered the Controller board with my computer on and plugged in via LPT, the motors would make a bad buzzing/grinding sound.

It took a while with my limited knowledge, but I found out the motors were moving and checked voltage across the + - to find out they were getting between 0.5 and 3-ish volts, on both the turn and step phases at the same time (on all 3 motors at the same time) :-s.

I haven't had the motors moving properly yet.
Could it be the LPT printer cable?


Anyone else had the same problem?

Cheers.
-James.


(Edit: It might be that the PSU sends power to the motors and the LPT sends signal usually, maybe.
But the LPT is sending power too)
