PETG on PEX Plates - How to Prevent Damage?

[MaverickNH 1]

I’m using a WhamBam PEX adhesion plate on my UL2+ to print Polymaker Polylite PETG. It didn’t adhere well at all at 70/80C, so I did an overspray of 3DLAC, which helps. Glue Stick didn’t help at all.

 

I ran a TempTower and the filament prints best at 260F. I’m finding damage to the PEX surface.

 

Can anyone suggest how to prevent such damage or alternative surfaces?

PEI plates are pretty popular these days. You could try that, they're not hard to find.

That's either a typo or you've got some pretty weird filament - 260°F = 126⅔°C - I've never seen anything that prints that low at all, let alone best. (It would also mean your bed really can't handle a hot day)

Ha! Yes, I got my Cs and Fs mixed up.
