Anet A6 Bowden Extruder

thingiverse

This design draws inspiration from similar creations on Thingiverse, tailored specifically to the Anet A6. It enhances extruder resolution by 3.75 and requires a corresponding increase in extruder steps before fine-tuning. Upon printing and assembly, the guide arm part may require adjustments through filing or scraping to ensure proper pressure on the filament. After cleaning the holes and performing these adjustments, my unit functioned without any issues. The spring employed is the original A6 spring. A short length of plastic tube serves as a guide on the input side. Both this tube and the output tube necessitate cutting to a suitable shape around the hob. A thinned-down nut (M6) is used to clamp the bowden fitting. Updated STL files for the Body and Guide Arm were provided by Onshape on 26/7/2018, while a new Guide Arm with a 2mm hole was added on 31/8/2018. The Mount.stl file is designed to hold the extruder on the top/back left of the A6 frame.

In a separate matter, extensive experimentation with bed levelling led to the conclusion that bed springs should have minimal tension. Excessive tension causes distortion in the 'H' aluminium beneath the bed, complicating bed levelling and potentially causing Y bearing binding. This may necessitate adding Z end stop adjustments. Since adopting this approach, bed levelling issues have resolved. Search for NevG for other designs by this author.
