Hello all, first post after searching for answers regarding my issue with either this driver or my whole setup altogether. I’ve tried numerous sketches, from youtube clips to examples on sites like dfrobot.com but I can’t get my stepper to turn…
here’s what I have:
-Arduino Uno with latest IDE and GRBL installed (also tried older grbl)
both are 1.8 degrees, 4 wire bi-polar steppers.
Power supplies I tested with are 12V 1.5A (tested on the Nema 17 since it doesn’t ask for a lot of amps), 19V 5A laptop adapter and a 36V 16.7A power supply.
Tried wiring common anode, common cathode, tried wiring and sketch according to this instructables page, tried this and this and some other youtube clips and I’m going crazy. Tried switching the steppers wiring just to see if that would make a difference but all I could hear is a very faint buzz which becomes louder the lower you configure microstep dipswitch setting.
I did also open up the driver and I could see something very disturbing…motor wiring on the printed circuitboard doesn’t correspond to the labels on the unit. But I did try switching over the motor wires in all possible configurations, to no avail
I hope someone can walk me through this setup. I can confirm that my drivers and Nema 17 steppers DID work somewhere beginning this year and I haven’t touched them since.
I just received my Nema 23 units and thought to try them out but disappointing results up to now.
I will try inserting some pictures and code I used, but it was all copy-paste from the sites and videos I checked…
