Creality Ender 3 v2 with bltouch and duel z- Horrible noise when moving on z axis!

  • Help!!!!!! I ditched the Hemera and went back to the stock on my Ender 3 v2. I changed the Hot end and extruder from Hemera direct drive to the normal Bowden hot end and flashed with the current marlin. Now I am getting this noise. I am running a duel Z with 2 stepper motors on the one port. The voltage is 1.2v on the stepper driver. I am using the marlin from "" on both Hemera and Bowden setup. the prints come out perfect on the Bowden setup. I failed on 3 out of every 4 prints on the Hemera so I switched back. PLEASE Help!!!

  • @Cordero808 1. check the installation of z-axis pulleys on both sides, and adjust the installation tightening screws of pulleys
    2. Check the installation of the Z-axis coupling and screw rod, unlock the connecting screws of the coupling and screw rod, re-lock the screws, and re-vertically adjust the screw rod parallel to the Z-axis profile
    3. Unlock the connection of the coupling, control the operation of the Z-axis motor by using the Z-axis movement parameters, and check the working state of the Z-axis motor.
