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. 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.) 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 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. 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. 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. uHpe.
