I have an Ender 3 and I'm experiencing an issue where it won't print on the edges. Near the outside of the bed plastic just peels away. Bed is level - verified multiple times.
The nozzle appears to be dragging the freshly extruded filament away before it has a chance to cool. Straight lines and wide curves print well about 30 % of the time, and sharp corners and curves won't print at all.
The printer works fine in the center, but the outer 3 cm or so are unusable. Not sure what could cause this. I leveled the bed multiple times - even told the printer to move without touching it, just to eliminate incorrect leveling by slight play in the rollers. Head is the same distance from the plate in the center as it is along the edges. No irregular high or low areas - bed is perfectly flat.
Is this a known issue with the Ender 3? How can it be fixed?
I am using the stock fiberglass bed with the BuildTak surface.
