Refer to the pdf file. IMPROVEMENT ON THE FILAMENT SENSOR FEEDING The original design for the filament sensor holding mechanism was not effective. The filament bends during feeding and when filament is retracting during no extrusion print, it pushes back about 10mm drop. The filament needs space to move downward. At that point, the magnet holder will be bent even more, creating a sound as it's limited in its available movement. To better secure the position, I have designed a bracket/holder for holding the filament sensors. It is an easy fix with one screw. Remove the round magnet from the filament sensor. Keep it. Remove the magnet holder (keep it) from the printer frame using an Allen key. Keep the screw for the new bracket. 3. Position the bracket to align the sensor as well as the mounting hole. Use an Allen key to go through the hole and tighten. 4. Once tightened, reposition the sensor so that it will align with the extractor base. It should be exactly in line. After this, do a test print to see if it moves correctly. If necessary, smooth the groove by sandpaper...
