I have big problem with PETG adhesion - mostly I have to use huge power for removing my printouts and twice I even damaged PEI sheet covering the heat bed. Is it possible to reduce the adhesion - e.g. using some kind of separation?
Prusa states in the manual that PETG will fuse to the PEI and requires a separator.
I use Windex (blue window cleaner) as my final clean before the print. It leaves a small film that is just enough to let PETG release but still stick well.
Others us glue stick.
Thanks a lot.
