What happened? 

During XY probing, part of the Tool Offset calibration, if the same probes are not repeatable after multiple attempts, the printer will show the message "XY probing failed due to the low measurement stability". 

Error name: XY probe unstable

Error code: #17105

How to fix it? 

Calibration pin 

Ensure that the calibration pin is not loose and that it is free of any debris. 

Collision with the calibration pin key

If the nozzle crashes onto the calibration pin key, it can trigger the error. Ensure that the dock is not loose and that it is not between the locked and unlocked positions. 

Nozzle 

Ensure that the nozzle is correctly positioned in the Nextruder, tightened against the Nube if you are using a Prusa Adapter and that it is as clean as possible from any residue. 

Loose bed frame 

Ensure that the bed frame screws shown in the picture below are tight. 

If you notice a loose screw, loosen all the screws, and retighten them in a cross pattern:

• First, tighten the front right and rear left screws (purple arrows).
• Then, tighten the front left and rear right screws (green arrows).
