Hey everyone!
After a few weeks of trial and error, and after frying two RAMPS boards, I finally seemed to have a working configuration... except that it doesn't work. So I went back to the beginning and try to do a complete system check up to see if I have faulty hardware somewhere that's frying my boards....
Every part works, but one. Z axis is the problem. When I need it to go up, it will only move down, a fraction of the distance it needed to travel upwards.
I've unhooked everything, and taken a single Pololu driver and the motor wires, and connected them to an Arduino UNO. Using a simple program, I'm making the motors turn 200 steps in one direction and 200 in the other. When connected to the x and y motors, there's no problem, but when connected to the z motors they still only work one way. I'm supplying them with 12 volts.
Anyway, the only thing I could figure out is different from other setups is that the two motors are connected in parallel but with ONLY ONE connector. I figured that this might be a problem (too much current drawn by a single connector?) and might make it not work (?), but then I can't understand why the motors would only go down and not up, instead of not moving at all...
Does anybody have a solution to this? Has anyone experienced the same problem?
Thanks for your help...
