Hey there, first post – hope it’s okay to put out a request for some advice. I just started 3D printing a few weeks ago (got an Ender 3 S1) and contrary to seemingly everyone else online, I’ve had no issues whatsoever with bed adhesion, rather the opposite.
Mostly to this point, I’ve been using ‘EconoFil’ PLA from filaments.ca (which was tricky to remove until I bought a better bed spatula-thing). Yesterday I got a roll of Overture ‘Eco-PLA’, which I’ve printed with a couple of times using organic supports, and both times has left a really stuck-on, almost chalky layer of filament on the bed. This isn’t so bad if I’m printing with the same filament afterward, but the Eco-PLA is ‘Midnight Black’ and I want to switch back to the Econofil for another model, which is ‘Bone White’ and I don’t want the bottom to get stained with the leftover Eco-PLA.
Has anyone had any similar issues? Any foolproof technique for removing stubborn, very thin layers?
Chances are you are squishing too much first layer, so adjust that first. Then print over residue with slow speed and 5-10° hotter than usual settings. Residue should come off with print.
