    • If the Z-axis is no longer working.

    • disconnect the power cable to the printer and open the bottom and on the mother board switch the cable to Z-step motor with the one to the extruder step-motor.

    • close the bottom and start the printer in setting mode.

    • request the extruder to move forward a little, and if the Z-motor move, you can confirm the Z-motor is working as expected.

    • You can order a new driver online.

    • I choose a DM556, because it is cheaper than the DM542.

  2. How to Repair the Creality3D Ender 7 Z-axis Control, Mechanical mounting of the driver: passo 2, immagine 1 di 1

    • Disconnect the power cable again and open the bottom of the printer

    • There is enough space to place the driver as on the picture.

    • You need to drill two hole in the frame on the back for the two screws to hold the driver.

    • Take you time to mark where you need to drill as it will be visible from the outside later.

  4. How to Repair the Creality3D Ender 7 Z-axis Control, Connect the power: passo 3, immagine 1 di 1

    • Connect the power directly to the 12V power supply.

    • Cut the cable to the Z-axis at approx 15cm from the plug of the motherboard.

    • Save the 15cm left!

    • Connect the A-, A+, B- and B+ to the right place.

    • Use as much as possible the X and Y connection as a reference to connect the Z!

  5. How to Repair the Creality3D Ender 7 Z-axis Control, reconnect the control signals: passo 4, immagine 1 di 1

    • Use new wires to connect the control signals from the mother board to the external driver.

    • Carry over the way is is connected on X and Y.

    • use later zip-tie to prevent all the cable you add to move and vibrate when the printer will be running.

  6. How to Repair the Creality3D Ender 7 Z-axis Control, Move the control plug: passo 5, immagine 1 di 1

    • The whole idea is to bypass the original onboard driver (which is under dimension, I think).

    • You can remove the mounting screws of the motherboard to remove the connector and reuse it on the similar position as X and Y.

    • OR you can simply solder the each wire, one by one.

  7. How to Repair the Creality3D Ender 7 Z-axis Control, adjusting settings: passo 6, immagine 1 di 1

    • I selected 2,1A: SW1=off SW2=on SW3=on.

    • I selected 3200pulses/rotation: SW5=on SW6=on SW7=off SW8=on to match the the movement of the printing surface.

    • You can close the bottom of the frame and connect back the power cable to give a try!
