Odious

The model you linked seems to have a backup battery and supports scheduled feeding, so I wouldn’t worry about a HomeAssistant failure too much.

By setting the plans or schedules, the pet will be fed in a regular pattern. Compared to the competition, the function will work even when no internet connection or when the Zigbee hubs goes down!

Regarding other tips about PETG: make sure the filament is dry. Wet PETG will pull lots of strings, no matter how “good” you’re tuning your retractions.

I’m not using anything specific for PETG clean up. IPA to get rid of oily residue and soapy water from time to time.
