🌑 Ender 3 Z Axis Not Homing

It does not move at all on the Z-axis and remains 3 - 4" above the bed during and after Auto Homing. Here's the detail : I installed a Creality Ender 3 Pro New Upgrade Motherboard Silent Mainboard V4.2.7 with TMC2225 Driver Marlin 2.0.1 & bootloader pre-installed & then a Creality BLTouch 3D Printer Upgraded Auto Bed Leveling Sensor Kit (the Z axis not homing correctly : r/ender3 r/ender3 r/ender3 • 5 min. ago Icy-Nerve3615 Join Z axis not homing correctly Help My x and y home just fine, but when it tries to home the y axis instead of going down to meet the limit switch it goes up and then everything resets to the position it was in before Vote Add a Comment Be the first to comment If the Z-axis does not move at all after the XY-axis finishes homing, it indicates that the Z-axis motor is not rotating. 2. Cause analysis Motor wires are not connected properly. 3. Troubleshooting and solution 3.1 Reconnect the motor cable of the malfunctioning axis. (The motherboard end also needs to be reconnected.) Specifically, the Z-Axis no longer moves down (the X and Y axis seems to be fine). Not only will it not Auto-home, but going to "Move axis" in the Prepare menu will also not move the Z-Axis down. I have attached a video I found on YouTube that showcases basically the exact same problem I am having. 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. A faulty microswitch stopped my brand new ender 3d printer from working properly. I could have got a new switch, but the fix was quick and easy. The z axis My problem is, that the z axis is not homing correctly at the begin of the print. It goes down and triggers the micro switch, goes up and stays at the incorrect height during the print. This results in non sticking of the first layer. This problem only accoures one or two times in a day. 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. The z-axis motor is not bound and is moving in both directions, just not after homing. I am also assuming the z-axis is supposed to be able to move down after homing, as the instruction for setting up the CRTouch specifically says to home the head, then to find the z-offset by lowering the z-axis. z4lIrbT.
