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.
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. I have my steps calculated, and squirting some plastic!! Problem is, the Z axis does not move up while printing! stays at the same level during the entire print. I have to cancel everything. I have full manual control of all axis moving up/down/homing ect, all with manual control.You could write a small gcode with z moves and some xy moves in between for testing. That should work. Then add more and more of the print gcode making problems in the beginning until the problem reapears, then you know which commands cause the problem which should help finding the reason.
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 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?
