> - if applicable, swap the default, white Bowden tube by one that's heat resistant (Capricorn comes often as a recommendation), that's for your health Capricorn makes great bowden tubes, but even they're quite explicit about the risks of using any PTFE tubing--theirs included--inside a hot end at ABS temperatures.[0] The health risks come from toxic PTFE off-gassing above the normal temperatures for PLA (though it starts off-gassing in small amounts at around 200°C). It's nasty shit, and you don't want to be breathing it in. Heat resistant bowden tubing doesn't do anything about that off-gassing; it's just meant to help mitigate deformation of the tubing at higher temperatures. You're infinitely better off just tossing the PTFE-lined hot end and upgrading to an all-metal one. That anyone--cough, cough Creality and others in the inexpensive intro printer market--is shipping them on any of their printers in 2023 is just insane. 0. https://www.captubes.com/safety.html https://www.captubes.com/safety.html
