Power supply for Nema 23 Stepper ?
philf:
Hi Buell,
Why does the +ve from your power supply go to GND on your driver? I'm sure it shouldn't.
(Just to clarify This is to enable the enable (excuse the pun) if the control board enable drops out whilst the motor is not turning.) I can't do a sketch at the moment but you'd want a single pole changeover switch with the common connected to the input of your driver, one other connection to the Enable connection on your control board and the other to the common ground on the 5v supply.
Phil.
Buell:
No reason other than I copied it from somewhere ! .. Clearly if you think its wrong i will change it !
Buell:
This is how I made a Start..but then realised that the controller thing was not the same ! but seemed a good place to start !

Any chance that you could supply us with the manufacturer and model number of the boards that you are using?
I'd hate to see you unintentionally let the magic smoke out of your boards, and with the part numbers we might be able to find the manuals on-line and help you decode their "Chinglish".
From what I can see it looks like your set-up should work, you've got it turning so it's sort of working. But the people that write the directions are not exactly consistent/knowledgeable regarding their subject. Sometimes it requires a healthy imagination and a secret decoder ring to make any sense of their manuals.
This could be something as simple as your stepper driver board is looking for a "HIGH" level pulse on its' inputs, while your pulse/direction board is supplying a "LOW" level pulse.

looking at the diagram in post22
it looks like they got the stepper drivers supply wires crossed !
fortunately you wired plus to plus and negative to negative even though you using black as positive & brown as negative looks odd
and should look like the original diagram with correction
if the direction & enable switches toggle between +5V and ground/0V
you can try the second version alternative wiring diagram with 0V connected to the step , direction & enable negative terminals
