During printing and after 10 or 15 minutes, the head shift (y axes) and the motor is very hot.
I’ve verified Belt --> seems OK
Pulley --> seems OK
Axes lubrification --> done with PTFE
Hot head and cable do not interfere with the frame.
I’m a little bit lost, the shift appear after 10 layers!
At the beginning (just after assembly) it was OK. Now, 1 month later, it fails.
Do you have ideas?
