Flexion Extruders, inspired by the maker of Ninjaflex, are a robust solution for printing flexible 3D filament. The Lulzbot Taz 6 reputation has been earned by building on the success of several prior generations of Lulzbot printers.
The design offered here has these advantages.
- The head will mount into the Taz 6 with no modifications on the Taz 6 printer mechanically or electrically and uses the same mechanical mounting system as standard Lulzbot FlexyDually heads: one 3mm screw plus two 16pin connector.
- The head will have all the cooling of a stock Lulzbot V2+ current head.
- The Taz 6 limit switches and automatic bed leveling will work identically as a Lulzbot head.
- The Lulzbot FlexiDually firmware is used for this head.
- The only changes required from a standard Flexidually set-up are different e-steps for the direct drive extruders and a different spacing of the nozzles(closer)
This project assumes that no prior extruder head is used as a surrogate for parts. Therefore the parts necessary to be purchased and printed are listed in the BOM pdf. It is assumed that most screws and wire are available locally.
It also assumes that the necessary procedures and wiring diagram for a standard V2 Taz 6 Hexagon hot end be referenced for wiring the plug and matching the pin positions. This excellent Lulzbot provided document is located here: https://ohai.lulzbot.com/project/taz-6-extruder-assembly/taz-6/
The following tools are necessary:
1.Soldering Iron and electrical solder(recommended) for pins and heat set inserts
2.Set of ball-end metric Allen keys including 1.5, 2, 2.5
3.Wire strippers and/or razor blade
4.Wire connector crimp
5.Drill with capability of 11.5mm drill bit
The ducts are printed with the fan attachment down and supports for the rest.
Heat Set Inserts
As Lulzbot uses, heat set inserts are used for robust and long-wearing attachment points. They are easily inserted with a soldering Iron
