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. 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.) 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: 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. 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!) 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. Bmid.
