it'sr eally good. I'd have no trouble printing PETG on it on my i3 Mega.

Update on my PETG on Cr-10, still not working, i've tried from 60 to 80 C bed temp, still warps even with magigoo. However here's the interesting thing I've noticed, the one on the back is perfectly fine from 60-80 C, it's the one in the middle that warps, and it's just the front corners. So I'm really confused now, is that more of a nozzle issue or something?
