BMG Dual Drive Extruder Upgrade Kit For Creality CR 10S PRO With Slick Gear Housing And Zero Filament Jamming For Hella Smooth Printing And Knockout Print Quality

Single Pack BMG Dual Drive Extruder Upgrade Kit For Printers
✔️ Bondtech gears, zero jams, upgraded feeder tensioning

This single unit swaps out dated bowden feeders on popular enthusiast machines for a reliable twin gear setup. Users mount it directly to the stock stepper to pull filament through longer heat breaks without skipping layers.

✅ Direct swap replacement for stock feeder assemblies
✅ Tight gear mesh reduces filament slipping during rapid retractions
✅ Mounts to existing motor bracket using four countersunk fasteners
✅ Includes sensor spacer and cable routing clip for clean runs

💡 How does a dual drive extrusion train increase torque transmission for semi-flexible materials?
This handy mod resolves feed stalling near the melt zone by distributing shear pressure across two interlocking gear sets. Techies return to predictable layer bonding and reduced retraction failures because the drivetrain handles viscous polymers way smoother now.
- Dual helical teeth multiply push force without overheating bearings
- Reduced inertial load preserves acceleration curves on steep angles
- Modular spacer kit adapts to varying hotend shank diameters
