I am setting up my Taz 4 for the flexydually version 2 and was curious about the extruder fan plug in. Can I follow the instructions for installing the second extruder wiring from the Taz 5 assembly here: [https://ohai.lulzbot.com/project/c8d1632e-5df4-4844-8f4f-e653379a8fc3/a16b1f2d-5c1f-47fe-a83d-9d68cca5d62c/](https://ohai.lulzbot.com/project/c8d1632e-5df4-4844-8f4f-e653379a8fc3/a16b1f2d-5c1f-47fe-a83d-9d68cca5d62c/) Then when I update the firmware tell cura I am using a Taz 5 flexydually with the hexagon hot ends? -Joe ---

Does this help? [https://www.lulzbot.com/tool-head-adapters](https://www.lulzbot.com/tool-head-adapters) ---

Somewhat, that is where I started at least. I am curious about the second hot end (E1) fan connection to the Rambo. There are a couple really good of guides for setting up the primary extruder (E0) for a hexagon hot end, ([ohai.lulzbot.com](http://ohai.lulzbot.com), and [xrobots.co.uk](http://xrobots.co.uk)), but sadly my searches showed nothing for the second. From the Taz 5 instructions it looks like the second blower fan plugs into the 2 pins on the bottom row furthest to the right. I am just not 100% certain that is correct. Thanks -Joe ---

It looks like this is the pinout for the extruder on production Taz 5: [http://devel.lulzbot.com/TAZ/Juniperbush/production\_parts/Electronics/Extruder%20Connections/](http://devel.lulzbot.com/TAZ/Juniperbush/production_parts/Electronics/Extruder%20Connections/) ![Taz5-ExtruderPinout.png](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/4/431e6c58690090ea62f8bb92f8d5d3c0210b7686.png) ---

I believe that is for the extruder connection on the x-carriage. What I am looking for is where the plug labeled “new” in this document: [http://devel.lulzbot.com/TAZ/Juniperbush/production\_parts/Electronics/Internal\_Harnesses/CB-Extruder%20harness\_Build%20Process%203.0.odg](http://devel.lulzbot.com/TAZ/Juniperbush/production_parts/Electronics/Internal_Harnesses/CB-Extruder%20harness_Build%20Process%203.0.odg) plugs into on the Rambo board for the second extruder. Thanks -Joe ---

The plug marked “NEW” is for the second heatsink blower. The assembly of the TAZ5 control box has the wiring instructions for the second extruder: [https://ohai.lulzbot.com/project/c8d1632e-5df4-4844-8f4f-e653379a8fc3/a16b1f2d-5c1f-47fe-a83d-9d68cca5d62c/](https://ohai.lulzbot.com/project/c8d1632e-5df4-4844-8f4f-e653379a8fc3/a16b1f2d-5c1f-47fe-a83d-9d68cca5d62c/) ---

Thank you for your help, all of you, it is most appreciated. I thought that was where it plugged in, but wanted to make sure before I accidentally broke something. Maybe after I get my new extruder I will make a write up or video about the installation. **Edit** After browsing around on [ohai.lulzbot.com](http://ohai.lulzbot.com) on a full computer and not my phone I found the solution. [https://ohai.lulzbot.com/project/prep-taz-4-second-extruder/accessories/](https://ohai.lulzbot.com/project/prep-taz-4-second-extruder/accessories/). The E1 blower wires take the place of E0 blower wires on the Rambo board. They do not plug into the pins that i previously thought. -Joe
