Extruder Filament Replacement - Dual Spring
youmagine
I've modified my extruder filament driver for my QU-DB extruder (1.75mm filament) to apply more force to the filament. I believe this setup will also work on MK7 extruders, but you may encounter some issues with clearance. To achieve better grip and results, I replaced the original drive gear with an MK7 drive gear, which allowed me to decrease the stepper current and run my motor cooler. The design incorporates an additional 8mm spring to apply more force to the filament and a 624 bearing for enhanced stability. You'll need the following components: two STL prints, two 8mm diameter springs, and one M3 screw to secure the bearing.
