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!
Very normal when printing long straight lines. Nothing to do with the age of the filament. There’s already good advice in the comments. You can also slow down your print, especially the first 4-10 layers to help avoid this. The longer the layers have to cool before you drop more molten plastic on top of them the less they will contract.
