I got tired of listening to the fan run on high for 15 minutes after a print finished so I reduced the setting.
I had a print running, and the filament ran out. Bambu studio was running in the background so that I could check on the print periodically. It really should use notifications to tell the user about events such as print complete, filament run out, etc.
I finished what I was doing and when in to get the print, because I assumed it would be done. I was surprised to see it half printed and the print head parked and the printer silent. After a bit I realized the the filament had run out. There was no prompt to load filament, there was no way to resume.
I assume that the idle timeout which turned of the fans, etc. also just cancelled the print in progress. I don’t understand why. If a printer can recover from a power loss, it should be able to recover from going to sleep while waiting for filament to be replaced.
Can you imagine printing a multi-day print and running out of filament in the middle of the night and wasting 14 hours of print time and filament?
