Z axis movement not exact as dictated first time


Recommended Posts

Posted · Z axis movement not exact as dictated first time

I am facing two problem in my printer:

1) Firstly when I give a movement of like 1 mm to z axis, it doesn't move 1 mm but almost 0.5 mm and then in the next step given it moves completely 1 mm. (I have tightened motor shaft screw but could't solve this issue)

2) My print layer is shifting in X axis direction continuously , like each subsequent layer has a different starting point thus prolonging print along only X axis and only in one direction (+ve X axis). X axis and Y axis motors also become hot (I should say extremely hot) (My printer

Please guide me in both issue.

    I'm on phone. So short answer. Hot servos are okay. X slip is pulley set screw

    Probably motor. Tighten all 6 pulleys on x axis. Very very tight. Should hurt fingers. Z axis sounds more difficult. Is it umo?
