If prints are not sticking to the print surface properly that might be a sign that the bed is dirty. Time to clean it! Bad adhesion comes from oil, dirt or stuck filament particles.
Before you start:
- Make sure the bed is cooled down, not heated.
1. Remove chunks of filament with scraper #
Grab the scraper that comes with the printer and remove any remaining filament from the print surface.
2. Clean the bed with a solvent #
70% Isoproponal alcohol works fine. Grab a microfiber, put some solvent on it and wipe down the bed.
