Do you need to solve your filament guide problems?? Try this!
After trying this filament guide https://www.thingiverse.com/thing:2917932, my original extruder drive was still being eaten by the filament pression... I then added this one https://www.thingiverse.com/thing:3190254 but I could not say I was happy with the result... the filament did not flow smooth as it should...
Then when I saw my friend's new printer with the extruders on top it was my eureka moment!
After some research I did not find too much information about the subject but I found the two Things marked as remixed. Based on their design and because I like to develop my skills on Fusion 360, I designed my own nema 17 extruder motor mount for the 2020 extrusion rail with one back hole for a Drop-in T-Nut if needed.
I have two versions :
- 90º ( vertical )
- 60º (diagonal) - better to reduce the tube curve
In my case (Ender 3), I could use the original cables and extruder tube without any problems.
But now I want to do some better cable management, for that I will be ordering this longer cable https://www.ebay.com/itm/XH2-54-4pin-6pin-Stepper-Motor-Connector-Cables-Extension-Line-For-3D-Printer/183568661084.
My original cable is around 75cm, I will buy the 150cm one just to be safe and will post future updates.
UPDATE 07 Aug 2019
- second hole for drop-in T-nut in the front added
Enjoy and post your makes!
If you found my Things useful, treat me to a cup of coffee :)
