This is my version for the extruder filament driver for my QU-DB
extruder (1.75mm filament), where I wanted to have more force applied to
I guess this set will also work on MK7 extruder too, but may be there is room problems.
I have added an extra 8mm spring to apply more force to the filament.
Also I have change the bearing to hold a 624 bearing.
Parts that you will need:
- These two STL prints
- x2 Spring 8mm diameter.
- x1 M3 screw to hold the bearing
I used the original qu-db drive gear but I wasn't very happy with it, so
finally I changed to the MK7 drive gear which gave me better grip and
results. Also with the MK7 i could decrease the stepper current so the
motor runs cooler now ;)
