I'm having some trouble with my JGAurora printer, when the extruder moves to the center of the bed it also tries to move it down. The left z-axis stepper motor has the stop and can't move but the right motor moves making it not parallel to the bed anymore. Here's a video https://drive.google.com/open?id=0B8...Fo2NVNLS1VRRTA
Does anyone know how to fix this?
