I thought my Z axis must be off so I set it to auto home, then told it to go up 50mm and measured it with calipers. It was up exactly 50mm. So seems like it's going up the right amount. However, when I print it's like it's only going up 0.001mm and just drags. I can literally hear it grinding against the infill.

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:

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.

Problem: Z-Axis doesn't work during a print. It attempts to work, maybe climbs on the Z-Axis, but screws back down. It whines, too. But, Z-Axis DOES work while not printing. It doesn't matter if the bed and nozzle heating or not, if it's not printing, it works as it should.

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.

1) over extrusion. Too much filament so the previous layer too thick (at least in spots) If the Z steps/mm is incorrect for your printer arrangement then that will (obviously) cause issue since the Z is not going 'up' enough. First few layers might clear, but eventually it will fail. ^{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.

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.

Z axis not moving during print. hi everyone, so I recently have set up my new 3d printer. I have set up my printer and it works, but whenever i print the print just piles filament until it begins to stick to the nozzle. i'm just hoping someone may have had this problem before and is offering a solution.

I will check that out. When I auto home, it will move down just fine and will all be at 0 , 0 , 0. However when I try to manually bring up the Z axis on the screen, it doesn't move up, but the motor will run as if it is trying to. If I remove that z switch wire (I think it's called? The motor wire.) ^{During prints, the Z axis does not move and this causes the layers to print on top of one another. The nozzle ends up digging into previous layers.} Turn off and unplug the printer again. Remove the cable from your X-axis and swap it with the Z-axis cable. Connect both wires and turn on the printer. Send a command to move both axes. If the Z now moves but the X-axis doesn't, the cable is damaged. If both axes move, the cable and connections are good, and the problem is elsewhere. A 3D printer's Z, Y, or X-axis may stop moving due to loose nuts, inadequate lubrication, binding with the lead screw, a loose Z coupler, or faulty wiring. It can also occur due to a worn-out drive belt, a broken stepper motor, or a short circuit in the motherboard. 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. .
