Upgrade recommendations for Taz 6 Dual Extruder v2

General LulzBot TAZ
1

Hello. I have a Taz 6 with a Dual Extruder v2 and I never use the second extruder. The cooling performance is very poor and I don’t like the extra weight on the tool head. I would also prefer to use 1.75mm filament (read this is possible with the 2.85mm tool head, just need to tighten the bolts holding down on the filament and change slicer settings and extrusion speed). Is there any recommended upgrades or guides for converting my dual extruder into a single extruder with better cooling performance? I don’t mind taking the dual extruder apart and reusing the parts, printing new parts, and maybe spending a little but definitely do not want to spend on a new tool head, I’d rather put my money towards a Bambu P1S. Thanks for any suggestions.

Theoretically, the 2.85mm head can do 1.75 with some tweaks, but in practice? You’ll waste more time and filament trying it than just doing a real 1.75mm toolhead.

The cheapest to most expensive things that work:

  1. Cloned Titan v6 toolhead: Lulzbot Taz 6 E3D Titan/V6/Volcano Mount - Stock mounting method by Zorrobyte - Thingiverse
    You can take the wiring and harnesses off an old Taz toolhead and save some parts doing this, but in the end, I don’t think it’s worth the trouble. After buying the stepper, 5v heatbreak fan, titan extruder clone, v6 hotend, you’re in about $40-50, and it works, but isn’t great.
  2. Biqu H2 toolhead: https://www.printables.com/model/242120-lulzbot-taz-biqu-h2-toolhead-mount
    You’re looking at $60 for the toolhead Amazon.com
    You can take the wiring and harnesses off an old Taz toolhead and save some parts doing this, but you still need to buy a 5v fan, 24v 5015 blower fan. So about $80 all in if you re-use the wiring harness, and about $90 if you buy the harness and pins.
  3. M175v2: Fantastic toolhead, but it’s pricey. Get it from lulzbot. Costs more than a lot of faster, newer 1.75mm coreXY machines (I trust Auroratech’s recommendations), so… probably not great if you’re paying for it.
  4. P1S.

There’s other toolheads you can build, but if you can’t design and build those yourself, I wouldn’t consider those an option.

As for the v2 dual? You might be best off trying to sell it, or use it when you want to do ABS + HIPS or PETG+TPU prints. It’s still ok at those. It just sucks at PLA.
