1) Push fit

2) Bushings

3) No SAE version.

4) LM8UU

5) Less tools needed

6) One plate bed

7) Better belts

8) Better documentation (future)

When I have RepRap presentation I always say that I update my printer almost every week. If you watch my GitHub Repository, you must be puzzled now. It's a long time since my last commit there. But when you look closer you would find out that the printer lived in Felt branch last few months. It evolved into something much slicker, smoother and sexier. While keeping it's workhorse spirit.It was already build on many workshops and it speeds up the build by many hours! Forget glueing the bushings, that was soo 2010.Iteration 2 is the younger, cooler brother of Prusa. It has 111111 changes and it's 63 times better :-)I quickly pick some important changes of Iteration 2Where it is possible parts are just pushed in without any fastener needed :-)You have possibility to use Igus professional bushings, brass tube, felt, pla printed bushing or even printer lm8uu alternatives.All bushings are simply snap in mounted, you can easily maintain your printer!When you need your printer quick you can always find one of those at home :-)Are you sad?? You shouldn't be, parts will work with both metric and imperial fasteners.Get M3 for small fasteners (you need them for NEMA 17s anyway) or #4 imperial ones if you really need to.5/16 rods will work in place of M8 without any change!You asked for it, so you got it! :-)All M3 nuts have nut traps. I've done workshop where everyone had only one Philips screw driver and two wrenches fro M8 nuts!No jigs or measurement during print! Rods are exactly length you need from end to end.That's kinda hack. PCB heatbed actually works as second plate.But it needs no leveling at all and frees lots of space under Y axis for electronics or PSU to make tidy, cute printer!I use T2.5 belts instead of T5 for a long time, and it affects the quality more significantly then any lm8uu would ever do. Now it's official suggestion, get GT2 ot T2.5 belts and machined pulleys! Be professional!I get best team to help me manufacture the new documentation!Kliment and Garry Hodgson (you many know him form Prusa Mendel Visual instructions).Expect to see it pretty soon! And fully done in ThingDOC!Watch out my GitHub Flickr and Twitter to get latest updates!
