Hi,
Sorry I didn't keep it clear from the beginning. When I first tested I just plugged in all the motors and tried to move them one by one with pronterface. Some of them just didn't move (Z axis) and others did but erratically. In subsequent tests I just focused in two of the motors (X and extrusor) to keep it simple debugging the problems. Both of them behaves similarly so I deducted the problem wasn't in the motors. I can still play around with the others.
I understand the proper steps per mm was 80, I just couldn't make it work while playing with the VRef, the motor was just (what I think it was) skipping too many steps and either changing directions non stop or not moving at all.
I tried what you suggested, moving two motors at the same time (X and Y) but I'm having some problems because they won't move at the same time, the motor X will try to move and when that's finished then the Y motor will try the same (with no luck for both).
I also swapped the stepper drivers a bunch of times with the same results.
The extruder is working just a bad as the others, sorry if I didn't make it clear, let me explain myself. I'm just trying basic axes movements, I didn't start playing with the extruder yet and what I'm trying to say when I mention the extruder motor is just that I replaced the motors for the one I was originally using for the extruding part.
In the beginning I tested several movements but in the end I'm just asking the motors to go home, I didn't know about sending them direct orders and my only tool for this has been pronterface. I tried sending G1 X5 F3 to both motors with different steppers and they do the same, I included a video of the results. I didn't try but I highly doubt they will be able to move the belt.
I know, I'm a bit frustrated with all of this and I already broke some A4988 by doing exactly what you said, maybe in the process I also damaged the whole Arduino or Ramps and that's why I'm having all these problems.
I'll do some more tests as the ones you suggested and if nothing works I'll think seriously about replacing the whole board.
Thank you very much for your time.
