I spent 3 months working with support, they replaced just about everything related, eventually sent me a whole new printer, and the new one had the exact same issue out of the box.

It starts too low consistently, so filament builds up constantly till it drops and ruins the print.

I can’t print anything bigger than 20cm² without it dropping a giant blob somewhere in the print and ruining it…

Always perfect first layer is not real, and my experience is that they are distancing themselves from the promise they made when the mk4 was announced.

FWIW, I’ve been a long time Prusa user, but I’m returning my Prusa mk4s and wouldn’t buy one ever again.
