@uint8_t yeah I think the first layer z needs adjusting. Yesterday it finished a seven hour print mostly perfectly with this white filament so I'm not sure what's changed.
@th check the nozzle, and clean its underside with a wire brush (careful around the heater block cables) and an IPA-soaked paper towel. if it's too dirty, I usually remove it and burn it out with a propane torch.
the problem is when the nozzle accumulates too much gunk on its underside and that causes it to stick to the printed plastic.
But besides, I do think your first layer z height is too much.
@uint8_t i recalibrated the first layer Z to be much closer and it's doing well so far with this platter full of clockwork.
@th looks like z height offset is a bit too much, I would reduce it by 50-100 um
