Printrbot Simple DDE, JL Style
thingiverse
After extensive experimentation, I have designed an extruder that meets my satisfaction. It features an open structure for easy cleaning and accessibility during loading/unloading. Compatible with my 300mm No Sag upgrade, this extruder has been running smoothly on my machine for several weeks. However, its compatibility with Ubis hot end is uncertain due to potential heat transfer issues. It works flawlessly with an E3d hot end. I reused components from my Printrbot wood DDE and added a filament guide that attaches to the 300mm No Sag bearing plate for convenient spool placement. Please ask any questions, as documentation is poor. On June 24th, I released a front-end version "JL-DDE-Simple-Double.stl" designed for Double Precision mod. On July 28th, I uploaded a revised extruder to eliminate cantilevered bearing post issues that could cause alignment problems due to warping from the extruder motor heat. The updated files are "JL-DDE-Simple-Double-2014-07-28.STL" and "JL-DDE-Simple-2014-07-28.STL".
