Printer: S5 w/material station and air manager.
Software version: 8.3.1
Problem:
After finishing printing with white filament using a 0.8AA nozzle.
The next print-job was also assigned the same white filament, but I changed the nozzle to
a 0.4AA nozzle which previously had printed black filament.
The printer detected the nozzle change, but failed to understand that the changed nozzle had to be cleaned before starting a new job.
This resulted in a couple of black layers in the printed object before the content of the nozzle changed to white.
This should be easy to fix in the software.
