Yesterday morning I came down to a printer vat with no resin left and my z-axis motor no longer moving. I cancelled the print but the build plate did not move. I was able to get the build plate and VAT out and when I tried to move the plate head up, just a loud cranking noise.
I turned the printer off and I can manually move the screw up and down and the plate head moves freely with no issues, but when I try to move it with the settings, it just sounds like it’s skipping.
Here’s a short video of the sound: https://youtu.be/cyuRtepsRPk
I’ve checked the cable connections to the motor and board, both are snug.
I’m wondering if the screw or motor are broken due the resin running out and maybe it sticking to the FEP?
Is there instructions on how to remove the motor and screw and how to check each for damage?
