- Master data of CC2 Control's copies follows Spoolman (name, brand, colour, diameter, density, net, tare, price; not the material, which was fitted to the tray). - A loaded spool's rest in CC2 Control is set to Spoolman's via /api/spools/adjust once everything is booked (old copy after the roll printed in the other printer, weigh-in in Spoolman); the resulting correction is not booked back. - Copies of spools archived or deleted in Spoolman are deleted from CC2 Control when no tray holds them (library limit 128); an outage never counts as deleted. - A roll that ran out is archived in Spoolman (setting, default on); a scan of an archived spool maps nothing. - A roll scanned again with unchanged tag data and put back into its old slot (after printing in the other printer) is recognised. - Tag generator: "Neue Spule" creates spools in Spoolman from an existing or a new filament (and vendor), labelled vendor + id, then opens the tag.
