"...for a particular PLA that may just be garbage..."
That appears to be a big part of this. Every printer will be at least slightly different, but 220 as a print temperature for PLA is pretty high. A 90° build plate temperature for PLA is well above the "Glass Temperature" of the material and would normally be considered a "Bad Thing". It isn't shrinking at that temperature because it isn't hardening.
The only roll of filament I ever simply threw away happened a couple of years ago and was an Amazon purchase of Sunlu silky. It was just really bad and near impossible to print. A lot of people use Sunlu without any problems so I just chalked it up to a bad roll.
Once burned and twice shy - I've never bought any more Sunlu.

I think I've solved this. No cooling for the first layer and set the plate to 90! Anything lower than that and it just doesn't stick. So this may be more of a PSA about Sunlu PLA. I've used their PLA+ Silk and that printed fine at 210 / 60 but these two standard PLAs were ridiculous to get adhesion.
Edited by BumbletoonIf there's any better way to do it bar glue, tape or spray I'd still love to know how.
