I’ve seen the alcohol recommendation already (91% minimum) but have you tried washing the bed with hot water and dish soap? Sometimes when my bed adhesion just won’t take I find dish soap solves it instantly.
PLA does have a shelf life, if cleaning the bed isn’t working getting a fresh roll could definitely be worth a try. PLA+ in particular has always seemed extra finicky to me.
Yeah as soon as I realized I was enjoying myself, I ordered a few roles of different materials. I'll give them a try when they land.
Dish soap is my usual go to!
it has been a while since I've printed, but now you mention it yes I seem to recall never having good luck with pla+
FWIW I wouldn’t do dish soap like all the time, I only go to it when IPA isn’t doing the job. Come to think of it, since I switched to 99% IPA I haven’t needed to use dish soap at all; doesn’t seem to leave behind that residue.
As always, experimenting is the key. If you’ve eliminated wet filament, z-offset calibration, nozzle clogs, nozzle heat, bed heat, bed cleaning, model issues (e.g., low surface area needing brims), and filament feeding issues… that PLA may just hate you.
Dish soap is better than alcohol, especially if you're cleaning the bed in a sink with lots of water to rinse all the accumulated oils off.
My experience has been the exact opposite. Dish soap cleans lead to a lot of lifted prints on my Bambu smooth and textured sheets. Dish soap followed by IPA works better but seems pointless when IPA alone works best.
