Adjustable Extruder Tension Bar for AnyCubic Kossel Linear Plus

Last crawled date: 4 years, 2 months ago

This is a replacement extruder bar for AnyCubic Kossel Linear Plus (and any of the rest of the AnyCubic lines that use the same extruder setup) that allows for adjustable spring tension. The part uses the stock hardware, plus an M3 nut in the spring seat.
After loading this TronXY Orange PETG into my AnyCubic Kossel Linear Plus, I quickly found out that the non-adjustable extruder tension is way too high for this softer filament. I had to limit retraction count to 2 per 5mm in order to avoid flattening and grinding the filament!
I initially added rubber bands to the handles to reduce the pressure on the filament, but needed a more permanent solution with a more repeatable setting for switching between filaments.
Tolerances are set for my printer, so please let me know if it works out for you!
