Hi!
I did find where the problem was, I changed the Y and X motors from 1.8 steppers to 0.9 steppers a while ago. It looks like the holding torque of the 0.9 steppers was too low. When I stepped back, and mounted the 1.8 steppers, the printer worked as it always have.
I'm glad you solved it. Typically, 0.9deg motors have a little less holding torque than 1.8deg motors from the same manufacturer with the same size and rated current. Example:
17HS19-2004S1 (1.8deg) 59Ncm
17HM19-2004S (0.9deg) 46Ncm
It gets more complicated if you change the motor length or rated current at the same time.
