Powder-coated PEI users: How does your finished print come off the bed?

When you remove a print from your (cooled to room-temperature) powder-coated PEI sheet, how would you describe the part's adhesion to the surface?

At the end of a typical PLA print (once the surface has cooled) my parts slide right off the bed. You don't even need to touch the part, just flip the surface over and it will fall right off. This seems unusual to me because my experience with PEI is that parts will grip the surface even after it cools, typically requiring a gentle "snap" to remove the part from the bed (which typically suggests excellent first layer adhesion in my experience).

I ask because I've had bed adhesion issues from day one with the MK3 (corners lifting, and parts regularly detaching mid-print). I want to see if my experience with parts sliding off the bed at the end of the print was normal behavior or indicative of poor first-layer adhesion.

Thanks, everyone!

ABS and PLA slide off. PETG requires a little more work.

PETG just lifts off when the plate cooled to room temperature 17C

For me ABS sticks too well - so I use glue stick.
For PLA I wait to cool down then some bending (in and out) and it comes off.
For PETG I make sure I touch the surface of the sheet before printing, when the plate cools down parts just pop off.

Same for me, PLA\PETG has just released itself when cooled but ABS stuck properly last time I used it and I thought that the textured surface was going to rip off the plate trying to get it off.

I just tested soem new filaments. I have found soem PETG and ABD requires a little mroe effort.

I recently started reserving a bed sheet for each fimament type.
