Hello All,
I have looked high and low for guides to upgrade the TAZ 6 hotend but have not managed to find one that exists within the current webspace. This has led me to create a custom solution to fitting a E3D V6 with the original extruder and fans. My current issue is powering the heatsink fan with 24v continuously. I have looked at the schematics but have not been able to locate a place where I can power the 24v fan that comes with the hotend. Any help would be appreciated or if anyone has those guides from 10 years ago, that’d be sweet.
The heatsink fan source used in the Taz machines should be 5v, constantly powered. I would recommend buying a 5v fan.
If not, a constant 24v source can be found by going straight from the power supply. I would recommend throwing a fuse in there though, otherwise a fan failure could have dire consequences.
Or just spend a few dollars on a 5v fan.
Get the 5v fan.

My only worry with the 5V fan is that it will not be sufficient to cool the heatsink and cause problems down the line.
The voltage of the fan doesn’t provide cooling, the CFM of the fan does. As long as the 5V fan has the same or higher CFM, it will do the job.

Right. That part I got, but the fan on the original E3D is documented having a range 10 - 15 CFM. The 5V fans are on average documented at for 3 - 5 CFM. I read the on the E3D v6 datasheet that 4-5 CFM is sufficient to cool the heat sink so I order a couple of 5v fans and hope for the best. Thanks for those for contributing.
Good news, I managed to create some decent parts for the conversion process. I have a custom hotend mount, heatsink fan duct for the E3D V6 hot-end and I managed to create some fan ducts (not thrilled with the design) for the 24v dual fans on the sides. I have wired everything together and now in the process of fine-tuning the firmware. Everything I am doing is meant to be plugin and play with the TAZ 6. If anyone is interest on the some documentation, let me know and I’ll continue writing my progress as I go. If not, I’ll shut up and keep trucking.
It never hurts to have good designs available. If you’re up on github, that’s good place to post everything involved with it, or you can just post models on printables, thingiverse and such.

Hello All,
I can confirm that my retrofit is working. I printed some prototype pieces and a benchy with it. Right now I am testing PETG material and trying to tackle some issues. Mostly I am wondering if having dual fans is causing a bed adhesion issue but that could my settings during the test prints.
I have not written a tutorial on the process, but I have managed to document my materials and my sources in case anyone wants to try it on their own. Feel free to check out, I’m always up for answering questions.
