Advice for nylon/PA warped prints not sticking?
Anyone have any advice with nylon aka polyamide and sticking to the bed plate? I've got an h2d (enclosed, heated) and printing without part cooling. The bed is pei with glue stick. The part is a rectangle that's 2x as long as it is wide. It warps no matter the bed adhesion tricks I use.

Assuming you already cleaned with soap, checked Z-height, perhaps tried a different adhesive (I can strongly recommend 3DLac spray) etc:
Check if there are beds for PA for your printer. I think Prusa had a specially coated one specifically to fix this issue, perhaps there's also one for yours. Nylon just hates to stick except to itself.
Some people print things at an angle I've heard. Uses more support material though
I've had solid luck with a garolite sheet (place I buy from has fr4 on steel sheets), pretty much what I've been using for most prints as it's durable and just works. I use a few drops of a Nano polymer adhesive that I spread thinly over the surface, found it helps with release. I'd actually really recommend something like that over gluestick, less messy, easier to get even and it'll hold, good for a bunch of other materials as well.

Back when I was doing nylon I used kapton tape and glue stick with pretty good success. Iirc ~285c hotend and 90c bed.
