Saturn Ultra 4 Z axis sudden humming and no longer moving.
Hello all, looking for some assistance in diagnosing an issue that suddenly arose. The printer was going just fine, printed 6 plates over the last 2 days, then mid-print on a plate, the Z axis just froze. Turned off the printer when I heard the sound of humming like the motor was trying to turn but couldn't. I'm not sure what could have caused this mid-print, and cannot find the solution myself easily.
- The build plate is not stuck to the tank, as you can see.
- I've checked the cables on the back, and they are all untangled and undamaged
- The Z-axis lead screw seems to be able to turn and move the build plate a bit, only by spinning the screw
- No debris in the Z-axis motor area
Just really confused. Maybe the motor just went, and I need a new one? Any insights are super helpful!
