Calibration fail

Hello Prusa-community,
I have a problem with my mk3. I need to calibrate them but he makes little jumps between each calibration point. So I replaced my pinda with a new and set it in the right hight. But I not works, I uploaded 2 video to YouTube. So u can see my problem.

I hope anyone can help me.

Best wishes

RE: Calibration fail

is normal.  It is seeking the magnets under the printed circles.  Aren't you supposed to have a sheet of paper between the head and the metal?  that could make a diff since it is seeking the point where it barely drags the paper.

Yip, thats the normal adjustment, remember how long it took, was a long 12 minutes. 

And yes Dan, you are correct  needs a sheet of paper under the head on all 4 points, says if it catches the paper at any point to switch off immediately (And it will restart the adjustment I assume)

Tank you very much!...

Can also confirm that this is correct behaviour, just done a recalibration on mine (MK3S+) and that's exactly how it works.  Takes ages and is very noisy!  As Dan says it is important to have a sheet of paper (just ordinary A4 photocopier paper will do) between the nozzle and the bed at each point.  It will protect the bed if there are any problems!
