A quick question. Can anyone clarify the wiring between the Optoport V3 breakout board and the DQ860MA stepper drive.
I ask because the breakout board has DIR, STEP, GND & ENA while the drive has ENBL-, ENBL+, DIR-, DIR+, PLS- & PLS+.

Is breakout board open-collector outputs? do you have manual or online link.
General arrangement would be one of:
BOB output connects to + input of drive through suitable resistor, all - inputs connect to BOB GND (active high outputs)
or
BOB output connects to - input of drive through suitable resistor, all + inputs connect to voltage source on BOB (open collector outputs)
See attached file, well if this worked.

Hi Jim, Just take the negs (-) to any Gnd's on the Opto V3 you won't need any Resistors the drives will work fine.

In this case STEP = PLS if that helps further. ..Clive
Thanks for all your advise.
Many more to come. Lol

OT, many many moons ago I used to have an identical colour Clubman 1275GT, bored out 1340cc, blueprinted, 731 cam and twin downdraft webers with a small bonnet scoop. Was fun on and off the track!
