New firmware broke everything

Sinece the last update Slicer and Printers. All my 6 printer underextrude and string.

PETG and PLA are ugly. The only variable that change is the frimwares. I have orders and now I can print one single one with quality.

I add proof of before and after.

Can someone help. M Y alone?

RE:

If the new firmware broke things then revert to the previous one? Add it to the pendrive ( so that only single firmware file is present on the pendrive along the gcode/bgcode files, reboot and double press rotary knob when booting and it should ask for firmware force write, allowing downgrade)

See my GitHub and printables.com for some 3d stuff that you may like.
