When loading PETG system will not allow you to select a PLA unless you change petg to PLA - my K2 plus is same exact way and it’s really really really annoying
What do you want to do? Mixed PLA and PETG prints work, I have used one as the support structure for the other already. I have set PLA in 3 and PETG in one of the 4 slots of the CFS Lite currently,
