helixscreen (prestonbrown)FirmwareConfidence: Medium

The pre-print fit check on a Snapmaker U1 reads nozzle sizes from the config file, which says 0.4 on all four heads, while the firmware's real status says 0.2/0.4/0.4/0.6, two of them high flow. It also judges heads the job does not use and never checks flow type, which the firmware refuses at print start.
