Why this going wrong?
I am printing 6 similar pieces, but two case me problems. They don’t stick w bed plate anymore. I heat it on 85 degrees. Can be that problem?
not enough hot. Print take 5 hours.
Start by thoroughly cleaning the print-sheet.
Cheerio,

I did it, before I print what is on pics 😉

It may not solve the problem but 3DLAC spray works exceptionally well - sticky when hot, comes off easily after cooling. I found getting consistency with cleaning alone tricky - especially if the printsheet is used with multiple materials.
The light smudges on the build-sheet are filament residues, some filaments are more prone to these than others, they are probably related to the pigment; they can largely be ignored. The dark ones are probably fingerprints and the oils in them do cause poor adhesion. Look up threads about sheet-cleaning.

will try with 3DLAC spray...i was use this in pics...

i we cleaned it with this "alcohol". More supprised is that only two pices was afected...rest was fine printed 😉

That's a "polymerization accelerator" for polyurethane, completely different world than thermoplastic materials (talking entry-level 3D-printing - if you have a "wizard" in the shop that's different but then he should be able to fix the adhesion problem...)
Recommendation: Switch to a standard work flow: clean the sheet thoroughly (isopropyl alcohol aka "IPA" would be considered "standard"). Either go for "clean surface" (in this case clean really thoroughly after using the Cotol-240 stuff) or standard adhesive / release agent (just get the 3DLac or something that is proven, not a generic glue stick. Some brands do not work)
It's worth a remedial clean with dishwashing detergent (dawn/fairy) and very HOT water. There are lots of threads here about the method.

i am trying now also that way....get ideas....for future, which is important, and test them too 😉
