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.
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:
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.
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.
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.
Stealthburner. I can't seem to figure out where I've gone wrong. My z axis won't go up, but only while printing. It homes as expected, I can manually (via web/front panel) move it up and down, and there seems to be no rubbing anywhere. It's like it's stuck on the same layer but only when printing.
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 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.
