Bed leveling failed. Sensor didn’t trigger. We can't even calibrate Z
The other day, the message of the topic title"Bed leveling failed. Sensor didn’t trigger. Debris on nozzle? Waiting for reset."
suddenly appeared. And, I can no longer print.I still get the same error message, so I tried doing Z calibration.
We cleaned the nozzle according to the instructions. Now the material comes out cleanly from the nozzle.
I still get the same error message, so I tried doing Z calibration,
but the same error message was displayed and even the calibration could not be completed.
Is there another way around this?

Could the Pinda have moved?
Is the Pinda responding to metal, ?
Check that the sensor status changes with the presence of metal near the pinda tip.
Is it possible that the pinda wire has metal fatigue, which can cause intermittent functionality?
Mine failed after a lot of use 
this was on a mk3S which uses a four wire cable, the Mk2 and Mk3S+ use three wire cables.
If I recall correctly, I sacrificed an old USB Cable, to source flexible wire. and I used heat shrink cable to insulate the joints.

Thanks to you, the calibration worked!
When I checked the height of the pinda, it was higher than the manual,
so I adjusted the height.
Then the error message disappeared.
It looks like the pins were simply misaligned.
Thank you for your help.
Sincerely, Shinya

Thank you for letting me know.
I will use it for the next maintenance.
