Re: yet another powder coated steel sheet
It seems like more experienced users who may have come from other 3d printers or have experience with other beds are the ones with issues on the PC sheet. Probably because they are already used to other procedures for those other sheets - just my observations.
I'd class myself as experienced and I love the PC sheet over every other surface I've printed on in the last 9 years. I've been all the way from aluminium, glass, rubber, PCB material, Blue tape, ABS juice, Glue stick, hair spray to PEI sheets and finally PEI PC and I'd never switch back.
I looked at the stats for my Mk3 this morning, in 29 days and 9 hours of print time I've had 2 failures where a part detached from the bed mid print, both were tall parts with a small surface area in contact with the build plate. I really can not fault the orignal PC build plate for adhesion and the surface finish is very satisfying to me.
I've ordered another sheet from theking to go on my mk2 self build as I've found a mk52 style bed (with magenets) in the correct configuration to fit the mk2 frog (4 corner holes, 2 central holes) that runs on 12 volts.

Hopefully, Prusa continues to make them. I have V1-V4 (V4 in route), matter hackers, and one I had painted at an auto body shop.
I prefer Prusa. But the difference in print results is not huge with V3 and V4
