Z axis get askew during calibration (right Z motor goes up)

Hello,

 

My printer has been successfully printing about 1km of filament since 2016 (so not a huge usage).

After a failed print last week, I decided to run a Calibration XYZ.

During the calibration of the point 2, the right Z motor goes up making very small abrupt moves.

The left Z motor seems to be working ok and slowly goes down.

After few seconds, the Z axis is not horizontal and gets askew.

 

My issue looks very similar to https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-assembly-and-first-prints-troubleshooting/calibartion-issue-only-the-right-z-axis-motor-is-spinning-when-calibrating/

 

FIXING ATTEMPTS:

  • I measured the resistance between the red/blue and black/green of both left and right Z motors and got the same value 1.1MOhm.
  • I swapped the left and right Z motor connectors on the motherboard: same behaviour with the right motor only.
  • I configured to Hi-Power mode: same behaviour with the right motor only.

 

Is there any thing else I could try to debug this issue ?

 

Thank you,

I ended up buying and replacing the right Z motor and it works like a charm now 🙂

 

However, still can find what was wrong with the previous one 🙄
