Taz 6 New Toolhead Carriage Conversion Mod - Use Toolheads from Taz Mini 2, Taz WE, and Taz Pro on your Taz 6 natively!

thingiverse

Ahoi'hoi! Lulzbot has upgraded their toolhead design to a smaller and more efficient package, thanks to the Titan Aero design. If you want to use these new toolheads on your Taz 6, you'll need to either A) Buy an overpriced carriage adapter or B) strip the parts off and mount them onto your own custom design that fits the 6. I've been working on engineering improvements for the Taz 6 and Pro designs. I'll be adopting the new toolhead style, as I don't want to keep two different types of toolheads on hand - ones that work only on the 6, vs ones that will work on the Pro or with a crummy adapter. So, I designed new carriage mounts (X Motor & X Idler). These are those! Please note the Idler assembly uses dual 625RS bearings and a different screw. It follows the Taz Pro design but with a lead screw mount. You'll also need to change the E1 harness connector to the new MicroFit 3 connector, and you may need to slide your bed mount 1mm to the right. IMPORTANT NOTE: The new toolheads don't have an "X Max" switch connected on the toolhead, and the Taz Pro doesn't have one either. The Taz 6 expects it on the toolhead. If you use this design, you'll need to jumper the "X-MAX" plug or mod the firmware; in the Marlin configuration.h file, comment out "#define USE_XMAX_PLUG". This is 100% required or the homing sequence will abort and start dropping the head into the 4th levelling pad instead of sliding forward to the home button. You'll also need to slightly offset the table position by adjusting the table mount. For example, on the Taz 6, the rear assembly spacer is 110mm. For this assembly, it needs to be 116mm (6mm moved towards the rear over default). Alternatively, you can mod the firmware to change the home button position. You're getting into heavy-duty printer mod territory by taking this on. This will completely void your warranty. If you want a 100% conversion, you'll need to change the electrical connector that terminates the end of the harness as well. All of this is something that you should only undertake if you know what you're doing. Also note, this mod will make it so that you cannot use any of the 'old' design toolheads - the toolheads that are compatible with this are the Titan Aero designs only. The single extruder v2.1 design won't work, but you may be able to use the Dual Extruder v3 on the "new" carriage design. Use this at your own risk. I've included a version with a mount space for the Z-Max (per the original Taz 6 design), and a version without the Z-Max switch mount (in case you want to use my other Thingiverse mod that adds Z-Max switches to the Z-Upper, like the Taz Pro). If you chose the version with the Z-Max switch mounted on the motor mount, the switch mounts opposite to the way it did on the Taz 6 - instead of mounting on the back, it mounts on the front - and you run the connecting wires through the pass-thru hole. I won't be using that design, so how it fairs overall is unknown. For the balance of the carriage parts required to complete this (eg, everything in this bundle not prefixed "Taz 6 Slim"), these are not my design - I've simply included the Carriage design files from Lulzbot's Workhorse Edition repository. These Are provided for convenience, and given the scope of license from Lulzbot, I am able to redistribute - but I am not taking credit for any of Lulzbot's design parts.

That should hopefully translate to more accurate, cleaner prints, with cooler running motors. Cheers!
