Prusa i3 MK3S+ Kit - XYZ calibration failed. Please consult the manual. - solved

I was completely desperate. This error message does not tell anything, only to check if all is assembled correctly.

I found out, in LCD -> Support -> "XYZ cal. details" you can find the skew value. Mine was 0.28°, which means "severely skewed" (more than 0.25°).

OK, I tried everything.

  • Adjusting the tension of the x and y belts
  • loosening and tightening every screw
  • flipping back and front plate of the assembly
  • slightly trying to rotate the heated bed

Nothing. The best value I ever got was 0.26° up to bad value 0.42° without any clue what correction would make it better.

My last calibration was at 0.39° with firmware prusa3d_fw_MK3S_3_9_2_3524

Luckily, 10 hours ago firmware 3.9.3 RC1 was released. The release notes tell something about new XYZ calibration algorithm and increased accuracy from 0.6mm to now only 0.1mm.
I flashed this firmware and I came from 0.39° down to 0.07°. The LCD congratulated me for my perpendicular assembled printer 😀 🥂 🍾

I hope this information may help you too.

Hi, I feel like I am in the exact same boat. Completely desperate and have checked every belt, screw, etc.  How do I know which Zip file to download?

Thx to erdega! Your tip helped me to pass the XYZ calibration successfully 😎 

Also the skew is awesome right now - only 11°
