Is it save to print without a PEI-Sheet on the mk42 heatbed

#1

I have got a mk42 heatbed without a pei sheet and i dont want to order one. I wanted to know if i can print on it without damaging it.

Thx :smiley:

#2

put a glas on it

#3

Can i print without any second layer like pei glass…

#4

no because it is a pcb heater and not like a mk3 heatbed with aluminium as main material.

How high is the pei sheet on the mk2s (0.5?)
