Reminder on PEI sheet usage

You should never have to use any adhesive(Glue Stick or hairspray) on the PEI sheet if you use PLA, ABS, ETC. Please try adjusting the z-offset before using an adhesive. You can find the steps on how to do this here First Layer Calibration (i3) | Prusa Knowledge Base

You can also find out how to properly use different filaments here Original Prusa i3 MK3S+ | Material guide | Prusa Knowledge Base. Hermes has a satin sheet, so print PETG there, as its adhesion may be too much for the typical smooth sheet.

Remember glue/hairspray serves as a release agent rather than forcing a stick. You don’t need a release agent for PLA or ABS, in fact it may make ABS adhere worse because ABS and ASA are prone to warping across the bed surfaces. PETG tends to adhere permanently to some surfaces so a release agent is needed to remove the part
