I hope this is the right place to ask for this kind of help.
I will add links to the parts I am using. Stepper motors 4 of these. : Stepper Motor :BOB :Driver Board
I am trying to use the 8 wire stepper in Bi-Polar parallel. I tie the wires as seen in the diagram Red and Blue = A , Yellow and Black = A- , White and Brown = B and Orange and Green = B-. When I hook A+ and A- and B+ and B- on the Driver board and have the 36V power hooked up I get a red light and blow a fuse. I am sure and have used a meter to confirm that
I have red and blue going to a single wire and that wire going to A on the Driver Board. Yellow and Black to a single wire going to A- , and the same for B and B-.
Please any advice as to what I have wrong.
Thank You
Don
