Hello mate!

I make auto bed leveling and there was a problem after firmware change, can see it on the photos. What it can be?

if it is a dual head this is the other nozzle who is creating this!

Sorry, i don`t describe, i have Prusa I3 printer.

is this a printer with two nozzles? (hotends)

no, just one

try a random startingpoint if thats possible and see what happens then?
