Weak mechanics, TAZ6, Dually heads.

I have a problem with the cleaning procedure if the autoleveling failes. The first cleaning I can change the Z-value from 1 to 2.5 in the startgcode but the other sequence I cant find.

I have serious problems with the head loosing alignment to the bed, after a wipe the head is out of level between the nozzels and either drag the econd nozle in the already layed down filament OR the distance for next layer is too much and it doesn’t bond.
