I'm trying to get back into 3d pruning after a long hiatus.
I found my old Anycubic Chiron, and thought I'd give it a go. Smaller prints seem fine. But anything longer than an hour. Come off like this. I say that what I mean is I excitedly take the multi hour print off the bed in excitement and for get to look at how it is.
The two longer prints definitely were at least in part still adhered to the print bed despite it being cold.
My next plan is to set a print away and check on it every hour or so and see if one side of the print has warped mid print (so far I've been printing before I go to bed, and only watching the initial couple of layers).
My guess it that the (pla+) filament is warping mid print... Its old I'll admit. But was stored in an airtight container with silica packs, and I dried it out before using. But any of your thoughts would be greatly appreciated!
Have you cleaned the bed with alcohol or a similar solvent before printing?
I do usually give it a quick scrub, maybe not the best technique.... But I blightly scrub the surface with a sponge.. admittedly using some mild soap and water, then wiping it down with plain water. And finally drying with paper towel. I also make sure the bed preheats beforehand to drive off any remaining moisture.
As other comments of suggested I will try using some IPA 99. If it continues this way I likely use some glue as well.
Yeah so I've struggled with warping too and for me by far the best bang for the buck was alcohol. I've never tried glue or hairspray or any actual adhesives.
You might try hairspray over glue as it's super easy to get even coverage and is significantly cheaper that glue especially with all these expensive "specialized" printing glues that have come out recently.
