Despite my flippant earlier post, I do have respect for the Mosquito design, which AFAIK was innovative. They even have a liquid cooled version which allows a hotend of up to 500C. Who else can do that? Unfortunately, those high-end hotends aren’t a supported option for the existing Bambu printers.
Slice Engineering sells a plastic repellent paint for nozzles, and I wonder whether it might help the existing Bambu nozzles with respect to PETG:
Anyone here tried it?
