That is weird. I'm not getting great adhesion with mine. I wonder if we're all getting different results, or if we're all judging by different standards...
Did you sand or clean your sheet? I just peeled the liners off of both sides and started printing.
(It's going to be really funny if some of you are printing with the liners on and that's the difference.)

I do have access to one of those. Thankfully it's not needed now.

Yes I removed the protective sheet and I scuffed the sheet with scotchbrite.

I must admit I don't get the adhesion I would really like. I could up the bed temp, just not overly enthused to do that. over at the SeemeCNC forum where I was led by a google search, some folks had great adhesion, others not so much, Almost all used the 3m adhesive to attach the PEI to their glass. Like others here have said having your z height really locked down is supposed to make all the difference. I am not sure I am where I really would like to be in that sense. But when I get no lifting on the corners, (drafts?) I always have to wait until it is almost cool before I can pry the piece off. So I guess I am not struggling with adhesion, so much as lifting at the corners like ABS is prone to.

it's definitely all about the Z height...
printed this all at once on the 12" nothing lifted though i did have to remove the PEI so i could flex it to remove the parts...

Hey Sniffle, it looks like you are using a brim, what size a brim are you using?
