This proved to be simply too much of a hassle to do properly, so no further development will happen. Were it not so, it would probably be moved, along with all my other designs to youmagine, because of Makerbot's blatant disregard of intellectual rights and them stealing from the very same community they emerged from.
UPDATE 13.2.2014. I am thinking of changing this design to be completely printable, and working on that currently. Stay tuned.
This is an upgrade for the UM, which enables you to get rid of the short belts on your X and Y axis. The original concept was made and developed by snowygrouch, as presented on the Ultimaker forum, the difference being that his design uses printed mounts for the motors, while I am trying to make the thing with lasercut parts. You can find instructions and files for his version here: http://www.calumdouglas.ch so go take a look.
The reason behind this upgrade is to have one less source of potential backlash, and thus more precision.

Agreed! I won't post to Thingiverse. GrabCAD or YouMagine (offering perhaps somewhat less liberty to users than GrabCAD) all the way!

Hi, I was just thinking, is it possible to 3d print out the parts with 4mm thickness ABS and then we assemble them into the direct drive set?

Hi, does anybody know where to buy 5/8 couplings ? A link to a german webshop would be nice as i can't find these things anywhere via google...

There's tons of them on ebay and they're really cheap. Just search for "5mm 8mm coupling".

Oh and if anybody is wondering, the blurry greenish-yellow thing in the background is the current H4 extruder prototype :)

Wow! When do you plan to release it? :)

As soon as I manage to cut out the latest direct drive prototype, and publish that, so I can test the H4 properly. It will all be done this week I hope.


Is this out of beta stage yet?

It's 100% working, that I can say. Although, I an thinking of redesigning it all with 5mm thick wood/acrylic instead of 4, for extra stiffness. When that is done, it will be out of beta. Unfortunately I can't say when that'll happen, because I'm working on 2 different new extruders, which have priority, not to mention my day job :)
