What extruder body did you use for the 0.75 version? The OEM or the 1013 moved motor version?

Heyo

I'm using standard greg's wade extruders as well as flyexystruders on the Version 0.75. It looks like there's room for 1013's moved motor version as well, and it should give you a teensy bit more X travel. We went with the std. extruder to keep assembly a bit easier, the m4 nuts used to mount the extruder are pretty inaccessible on the motor moved version when the motor is mounted.

The move motor body did not fit. With a dremel I took a few mm from the mount.
And the hobbed bolts are to long. My dremel took care if that too. :mrgreen:

Thanks for sharing the files.

Good news everyone!

We've got a fresh redesign of the Dual Extruder that's easier and just generally better. Take a look at Version 0.9 (we're getting super close to an official release!).

After a few weeks of testing, we found that version 0.75 of the dual extruder tended to drift out of calibration. The main culprit was the 2 point z-leveling system; even a small difference in the height of the 2 leveling screws will start to show up in the print after a few heat cycles.

The new version uses a single centered leveling screw (more like a dial now); and flexes both extruders together, rather than flexing between the extruders. We're super excited about the results, and hope you will be too.

All source and g-code can be found at http://devel.lulzbot.com/TAZ/Dual_Extru ... uder-V0.9/

Mmmm... up-down dial.

Pretty soon we'll be printing full size planets.

Looking good! I can't wait to buy an upgrade for my TAZ 3, so I can try printing ABS with HIPS or PVA support material.

If you start printing full-size planets, watch out for goons from Magrathea.

I've previously downloaded the parts for the dual extruder and printed them, but now the link above isn't working anymore and I need the details around instructions, etc. Any ideas what's up with the URL, or is there a new one?

Thanks!

Sorry about that, I changed things up a bit the other day and forgot to update the link.

Assembly instructions are currently in a document here: http://devel.lulzbot.com/TAZ_Accessorie ... tion_docs/

Look for it an an OHAI-KIT in the next week, It should make the assembly a lot clearer
