Strange moves on Z axis dual motors
Hello, I have problem with my printer. I have two motors on Z axis. I tried parallel conection and even mirrored connection to another driver, but i got same results. When I moving with Z axis with LCD controller, on of my Z motor moving wrong way sometime. Moving Z up for 10mm and my left motor go up all 10mm but right motor e.g. 3mm than go 1mm down, than few mm up, than down... anyone know, that I am doing wrong?
