1st layer great, next ones not sticking...
Hello all,
For a few prints now, I have a strange problem.
My first layer is printing perfectly but the next ones are not sticking, resulting in an awful structure (see pictures).
How should I troubleshoot this ?
I have a MK3S + MMU2S, printing with PLA and PETG with the same results. Even with brand new spools.

Hello Joan, do you see them now ?

How does the first layer look, you have a picture? Are the walls of the cutouts at 90 degrees in relation to the print bed?

Check if you are printing hot enough, or try 10 degrees higher.
Slow speed down.
Check if your nozzle is not clogged, move extruder higher, and extrude, check if you see bubbles or that the extruded material is to thin, if you are not sure, change nozzle, is only 10 minutes work, and then you now this part is good.
Do a cold pull to clean nozzle.
