How to Fix Z-Wobble in 3D Printing? 1. Clean Rust from the Z-Axis Rail A rusty guide rail can cause unsmooth Z-axis movement and contribute to Z-wobble. To resolve this, you can use a rust remover and a dust-free cloth to clean the Z-axis rail. First, move the Z-axis to the highest point for easier cleaning. The problem is the Z axis does not move up after the printing starts. It DOES however move during homing and in manual control. This results in the everything getting printed on first layer I am using firmware Repetier 0.92 btw. And the driver currents are adjusted correctly. (0.12 mA, they are small steppers!) However during printing of some test squares, its pretty clear the bed isn't printing level (some are clearly too close, some too far away), and watching the Z-Axis like a hawk, it doesn't move at all, which I am assuming it is supposed to? Using cura to print. Here is my start code: Firmware-related problems Malfunctioning Z-axis stepper driver or motor In the upcoming sections, we will take a deeper look at the reasons behind your Ender 3's Z-axis not moving, go through the potential solutions, and find out the most optimal lubricant choice for the Z-rod that is responsible for the Z-axis movement. Table of Contents If you find that your Z-axis leadscrew is properly installed and is not binding, then you should try lubricating your 3D printer, especially around the Z-axis. This can be as simple as using a lubricant PTFE spray or using a popular lubricant like Super Lube Synthetic Oil with PTFE from Amazon. I would test to see if your Z is moving backwards - with Z=0.3 I could see it was printing about half way up - if you move to z=10 it should move the bed down. Does it? I'm hoping it moves the bed up. If so then you can simply swap Z direction (several ways to do that) and swap the end stops. .
