I’ve got a Lab A1 with a couple thousand hours on it. Have printed plenty of bambu and sunlu PLA and PETG without issue.

Recently got some Anycubic basic PLA and have been experiencing absolutely wild shrinking and warping. For example, I’m currently trying to print some small round discs- the smallest being around 2cm across and 5mm thick, and the largest being 5cm across and 5-6mm thick.

Using a 0.2mm nozzle, textured plate.

The first ten layers or so are fine, but by layer 20ish, only the very middle of the discs is still in contact with the bed, and the edges are curling up to the point that in some places the first layer is literally above the top layer and the extruder is just scraping away material.

Bed adhesion is apparently good because the discs are not being knocked off the plate despite the aggressive scraping. 

I was using the standard bambu pla profile because it worked for sunlu and a few people online claimed sunlu and anycubic were similar. I just switched to the generic profile and then lowered the bed temp to 60 and extruder temp to 200. 

Digging around online I’ve found maybe one or two other people struggling with anycubic pla but I can’t tell if it’s the same issue or the same filament (as opposed to high speed or plus or whatever).

Is there a better profile out there somewhere or settings i can try?
