i have a problems whith the motors. Z axis move when i move x and y, for example i put g1 x100 y100 and the bed start to up and down quickly, stops, and then the x and y moves. is the same thing when i was printing. Other thing is the motors dont move fluidly, stop and start rapidly like vibrating specially when it move fast.
Other thing is i cant calibrate the z axis.i follow the flowchart but when i used M371, the bed up, but when i tried to move to the top i cant, is not moving, i can move only 20 mm to the top, if i use M371 again the bed downs to home and up to the original position.
How can i move X and Y without the z?
Thanks for the time
