Prusament PLA wont stick to Pei-Sheet
i Have printed with succes Prusament PTEG on a Pei sheet flex bed. i switched over to Prusament PLA and it will not stick to the bed it comes loose after the second layer.
cleaned the sheet with alcohol which did not yield an improvement
any advice is welcome
"PEI sheet" does not identify which sheet you are using. Both smooth and textured are PEI.
Bottom line - scrub your sheet with an unscented detergent like Dawn and copious amounts of water.
Dry it with a fresh paper towel. Finish drying on the heat bed. Never touch the print surface.
I second the "My prints don't stick!" suggestion to "Use soap and water to clean the sheet."
But after washing in soap and water, do NOT use alcohol after the wash. Soap and water works best as the last step in the cleaning process. And using fresh new paper towels as the scrubber and for drying then handling by the edges is mandatory. Short cuts will just cause you more grief.
These days, keeping the bed clean is the most difficult part of my printing.
