The dimensions are correct though, so we can eliminate one issue?
Any other filament you can try? When I worked at robo we got in a batch of ABS marked as PLA, similar issues. or could that be really old PLA exposed to the humidity for a long time?
Extrusion test, match 100mm on the filament, lift the nozzle off the bed and extrude 100mm and make sure it matches? I hope they didn’t change the drive gear size on me that will be a pain to figure out.
