🏅 Z Axis Not Moving During Print

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!) 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. 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. 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. For the life of me I could not get past the first few layers without the print turning to crap until I realized that the Z axis is not moving during print for layer change, it is printing the first 3-4 layers at the first layer height. 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. The Z axis works fine under the move axis option on the printer but doesn't move during a print. I have tried changing firmware to TH3D version and still the same issue no Z axis movement during print. 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 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. 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. The Z-Axis just seems to be completely disabled during prints. Here's what I tried (none of them solved the issue) Swapping the X an Z axis to see if the stepper motor is broken. Resetting all my settings. Inverting the Z-Axis. Trying new G-Code from Cura as well as the sample G-Code models included in the SD card. 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. drpc.
