I bought these several years ago for a project that never got off the ground. Trying to get the stepper going now for another project. I have some micro processor code that works with smaller driver/motor combos but will not work with the HSC86H driver. I think I may have something wrong with the wiring and have attached a picture of the HSC86H wiring. I do have a 24v 20a power supply for this setup. With my code the enable control is working as I can trigger the ENA port and the motor will lock. However, none of the movement commands are working. I am using this color coding of the wiring Red=A+, Blue=A-, Black=B+, Green=B-, Yellow=+5v, Brown=GND.

Any help/pointers would be greatly appreciated. Thanks in advance.
