Problem with arpstepper, green led is ok, not run nema 17

[adrian.laurel]

hello!

How good that this community has been created! I hope to be part of it! Maybe you can help me, I have experience with electronics and programming now I'm a bit lost with this problem ...

I have purchased my first arpschuino, with a card for steper motors. Arpschuino receives dmx and flashes green, great !, but the nema 17 motors are not moving ... they are blocked, so it receives load ...
I rule out possible problems, electronics ok, I have experience soldering cpb and fritzing, the 4988 driver is new, and I have tried several, correctly fed everything with 12v, the programming is ok, with the new nut (May 2021) in arpschuino and arpstepper example, where I edit address to include in programming, I attach code. I am using dmx enttec open usb to dmx, and VSA software that commands dmx

Hello Adrian, welcome in the arpschuino community !
Looking at your code, I realize that you have defined 0 as DMX address:

Code : Tout sélectionner

address=0;

The address must be set between 1 and 512 (more exactly, 512-the number of addresses used), it is true that in programming we are used to starting from zero but here it is the logic of the DMX which is used.
