the left and rear Z-axis remains stationary
I've had the CoreOne for a few days now. At the beginning everything worked fine, but since today the left and rear Z-axis have failed. They no longer move. The right side runs.
What can I do?
RE: the left and rear Z-axis remains stationary
Make sure the lead screws are lubricated. Several users have reported that they were dry in the Core Ones they received, and that lubricating them fixed sporadic blockage of the Z drive.
To get the bed (roughly) levelled and unstuck again, you can turn the lead screws manually after turning off power to the motors.

Many thanks for your help. It has worked. Everything is running again. Many thanks again 👍 👍 👍 😀

Had exactly the same issue, right and back lead screws stuck. While they looked shiny they were definitely dry. Manually put a bit of lube around where it was stuck and manually rotated the screws over the lube and that was it!
