Adjustable Extruder Tension Bar for AnyCubic Kossel Linear Plus

thingiverse

This is an adjustable extruder bar designed specifically for AnyCubic Kossel Linear Plus printers and similar models that utilize the same extrusion system. The part relies on stock hardware along with an M3 nut situated in the spring seat to provide adjustable spring tension. After loading TronXY Orange PETG into my AnyCubic Kossel Linear Plus, I discovered that the non-adjustable extruder tension was excessively high for this softer filament type. In order to prevent damage, I had to limit retraction count to two per 5mm of movement. Initially, I attempted to resolve the issue by adding rubber bands to the handles in an effort to decrease pressure on the filament. However, a more permanent solution with consistent settings was necessary for effortless switching between filaments. Please note that tolerances are set according to my printer specifications; kindly let me know if this adaptation works out well for you!
