I have noticed this as well, but am not sure oozing is part of the problem (I am also not quite sure it isn’t). Basically, if QR code fails and you resume, nozzle ends up too high. But if QR code is disabled, everything works fine. Feel free to add to this issue: Failing to read QR code is unrecoverable: Bed ends up too low (nozzle too high) · Issue #3329 · bambulab/BambuStudio · GitHub
