Just upgraded my beloved MK2 with a kit from Prusa, however when doing the first calib it gets stuck in an endless loop on:
"Searching bed calibration point 1 of 4".

The printer makes small movements but does not proceed.

How long have you been waiting? 

I had a similar issue after upgrading my Mk3S -> Mk3S+ earlier today, but I let the calibration run.  It finally completed #1 after ~6 minutes, then moved onto point #2.  Each point took about 6 minutes to complete, but in the end it finished and the calibration succeeded.  After readjusting my z-level, my Mk3S(+!) is back in action.

 

I noticed that with the Super Pinda, the bed calibration seems to take longer due to slower z-axis movements during calibration/pre-print. Not sure if this is normal or not, but the self-tests are OK and it prints at the same speed it always has, so I'm not concerned.

I have the same issue - just finished my upgrad to the 2.5s kit ( from a 2) . I runs through the XYZ 4 point calibration, then says failed. Did you ever solve it ? 

- Self tests passes.

- I check the PINDA probe with a screw driver (detects) 

I have also tried with both - pinda and superPinda settings, It does the same. ( I'm prettysure I have a super PINDA - 3 wires - kit was ordered in the last batch ever - dec 2020)

Did you have any detail about the fail message? 

Parlo italiano...but I'm not an expert....

It says "XYZ calibration failed. Please consult the manual" - I now realize this is different then the original problem from this thread. 

I followed : https://help.prusa3d.com/en/article/xyz-calibration-mk3-mk3s-mk3s_112351/#troubleshooting-the-xyz-calibration ( linked to from  https://help.prusa3d.com/en/article/calibration-failed_2033/ )

Did a full reset, it failed again, twice. I then powered down, placed the PINDA in the right spot, powered up, and checked the sensor - I got odd readings ( it would flip at the midpoint on the X-Axis) , but when placing metal under it, it would flip to 1 (detecting). 

The right hand was lower than the left ( by approximately 2 mm ). 

I changed nothing after this, and retried the calibration - and it worked. 

I hope future revisions would give more information on failures ( like stats on the screen ? I know there is not much there.)

Anyway. Thank you for replying. I am not sure what I have will help others, but its another place to find the links.
