03. Adjust the Feeder Tension

JellyBOX features a spring-loaded feeder with adjustable tension - this means you can print a wide range of filaments without a hiccup.

For PLA, PETG, and similarly rigid plastics, keep the tension at maximum.

For flexible filaments (TPU, Ninjaflex...), you want to lower the tension down. You cannot force flexibles; they will just bend. You have to ease them gently into the hotend.

The indicator is designed to work with filament loaded!
