In the case of only the Z-axis of your Ender 3 failing to home, we can immediately tell that the Z-axis endstop is the culprit, meaning that either there are problems with its wiring (especially likely if you have been working on your Ender 3 lately) or the endstop switch is not functional anymore. 18K views 1 year ago. Ran into a problem on my Ender 3 V2 with the Z axis not moving down when doing an Auto Home. After some research and testing found that a wire had broken in the ribbon cable The reasons that Ender 3 Z-Axis is not moving could be printing scale issues, motherboard failure, or eccentric nuts problem. To fix the eccentric nut issue, loosen them and do tightening them. For avoiding the printing scale issue, loosen the screws on the lead screw bracket. Z axis not homing Ender 3 V2 with new 3DTouch Solved Hello I just installed a Triangle labs 3D touch on my ender 3 v2. I wired it to the BLTouch port on the board. I flashed a UBL 10x10 BLTouch version of Jyers Marlin specifically this version (E3V2-UBL-BLTouch-10x10-v4.2.2-v2..1.bin). Creality Ender 3 X axis homing issue Ask Question Asked 3 years, 8 months ago Modified 3 years, 8 months ago Viewed 16k times 1 I bought an Ender 3 recently. Auto-home is on the right front moving away from the end stop. I did reverse the wiring of the X axis motor, it did not work. I had Marlin 2.x uploaded, it didn't work too. Marlin 2.x: If the stepper is driving the printer head away from the endstop on a particular axis on homing (in your case the X direction), there might be a few possible problems at hand: The stepper cables are plugged in reversed; The wires in the stepper cable are switched Plurrie Ender 3 V2 Z-axis homing VERY inconsistent Help Hi all, First time posting here, so hopefully I'm doing this right. My new stock Ender 3 V2 is having extreme deviations in Z-axis homing. When I auto-home, The nozzle will end up anywhere between perfect print height to a full millimeter off the bed, seemingly randomly. Written by: David Taylor Last Updated: June 20, 2023 Homing the axes is essential for your Ender 3 to know and calculate the X, Y, and Z positions, meaning that the failure of the homing process due to any reason will naturally halt the printer due to a lack of positional data and make it impossible to print until the issue is resolved. I've managed to loosen the wires from the terminal and place them in a correct way using a flat screwdriver that came with the other Ender 3 tools. After switching wires to correct position the z axis started to autohome correctly and z stop switch started working correctly. iXRHi.
