Taz 6 V 3.1 Dual buy or not to buy is the question?🤔

1

Thoughts? In general

Bed Leveling, Purging, and Swiping using multi-materials please discuss Extruder, firmware and CuraLE issues. I see nothing when I research this topic. I want to be able to print PVA with other materials to build casting models. In addition, the use of Flexy and other materials. Should I wait? Is Mosaic Palette going to be the future? Why are there no discussion about it? Is it not working well?

When I search this forum for “Dual Extruder V3” I get 50+ results. “Dual Extruder V3.1” returns 5 results. The difference between V3 and V3.1 is the mounting of the hotend, always on, fan.

I would suggest reading those 55+ topics and if you still have specific questions, you can ask them here.

I have read many of the V3 but that is why I have my question as is thx! I want to know specifically if these issues have been addressed in the V3.1. If you read my question more carefully I try to make this clear about firmware, CuraLE, and hotends. In addition, I clarified even further into which isses swiping, purging, leveling, etc.

Thanks!

BTW, I’m looking for answers about the dual extrusion future with Lulzbot TAZ 6 in general?

V3.1 was released to address the issue of larger than acceptable heat creep issues. IMO, it is not as successful as the solution discussed in https://forum.lulzbot.com/t/dual-v3-a-review-wait-for-v4-heat-creep-still-a-problem/6017/5.

There are no firmware changes, CuraLE changes, or hotend changes. There are no changes regarding swiping, purging, or leveling.

IMO, the LulzBot TAZ 6 is end-of-life. Its replacement is the LulzBot TAZ Workhorse. The “future” of dual extrusion is the LulzBot TAZ Pro. Some new products being created by FAME (Fargo Additive Manufacturing Equipment 3D) are backwards compatible with the TAZ 6. Again IMO, a replacement for the Dual Extruder V3.1 has a very low probability of being created.

I am just an owner of a LulzBot TAZ 6 with more tool heads than I care to list. I do have a Dual Extruder V2 and a Dual Extruder V3 which I have upgraded with a fan mount as documented in the above topic.

I am happy with my Dual Extruder V3 and have done lots of dual color prints. I haven’t had as much success with PLA / PVA prints but I believe I need to do more fine-tuning of the PVA parameters.

Thank you for your input…sad this not going to be developed further using the TAZ 6. I see what you are saying from the post and I’ve been watching since V2. The demand is there from the user end but the company wants to sell more printers not heads and software, I guess. Also understanding the Pro is a better way in theory of mutli-printing. If they are going to abandon their efforts then why not open source it and let the users take over?.. So basically, if I’m not going to be able to get multi-material capability from and only get color changes. I should spend my money on a Mosaic Palette Pro 2s or just stick with painting. But as far as multi-material I guess I have to wait. Maybe a competitor will develop something or 3rd party.

It is “open source”.

I did not know that, so users can take the base program and start modifying it? I did not realize that. I use OctiPi and I have seen the other Drunken Octopus but I did not know source code was available and how to access the the processor and language. I need to research that. Thx.

Also, to be clear were you saying the V3.1 fan upgrade from Lulzbot still needed to have a new fan?

I had read your link and this thread and confused what you were saying about the new fan mount with a new fan even on the the new V3.1. I see where you like the shroud and believe that is a bigger fix, thx

The Dual Extruder V3 suffers from an abnormal amount of heat creep issues. This can be solved in multiple ways.

  1. Purchase and apply LulzBot’s Dual Extruder V3.1 upgrade kit.
  2. Print and install the fan duct described in this thread.
  3. Search the internet for other fan duct solutions.

Option 1 will reduce the amount of heat creep issues but, IMO, not as much as option 2 or option 3. You do not need option 1 if you go with option 2 or option 3.

I am happy with option 2 but I remember seeing other options when I was researching option 2.

I bought a more capable fan and was happy with that solution. It has been a while, but if I remember it required soldering.
