@ Nallath,
could you give a little mor info abount the nozzle lift?

@ Anders,
did you made pictures while disassamble the core?

Small objects work pretty well, but it's quite easy to slice a model that takes about 8-12 gig of ram (as we haven't tried optimising this). The ollimex definitely does not have the resources to handle that.
I suppose for this one could install a HD on the Sata plug and create a virtual memory of it so it can slice on a SSD drive at a very slow speed? Just thinking outloud
That should be possible. Our tests also indicated that slicing speed is about 25% of a "normal" CPU.

Of course! It's actually a pretty cool system. There is a "switching bay" on the right back corner of the machine. If the machine wants to switch nozzles, it moves over there, wedges the lever into the bay and moves the head forward (effectively switching the switch). This lifts the nozzle 4 mm, so the difference between the two is always ~2mm.

THAT would be interesting to see in concept/detail... :-)

I did, but I will keep that picture for myself for now since I promised those who sent me the UM3 not to take it apart :-) I will send you a PM.

Could you tell us something about the feeder? It looks different from the UM2+ feeder (much thicker), but what has changed?

Edit:
I'd also like to see some video that was taken using the built in camera. The timelapses that are shown don't appear to be made by it, the camera angle doesn't match.

As far as I know it is the same feeder as on the UM2+
The built in camera was rather slow when I tested the UM3, it was more like a series of photos than a video stream and the resolution is rather low.
Still though it is very useful feature if your printer does not live in the same room as your computer.

I am even considering putting an UM3 in a separate building which is connected to the same wifi network as my house.
Being able to see what happens on the build plate and even abort or pause it remotely will save me a lot of trouble then :-)

We will most likely see new software taking advantage of all the new hardware in the UM3 in the future, I have seen some cool things that I unfortunately can not talk about yet..

It is the same feeder as on the UM2+, just that there is also a mirrored version of it now.

Picture of a UM3 next to a (very early) UM2+

The camera is fast. Cura just limits it. It's pretty easy to make it faster.

You can see it in action in one of the videos ;)
It is a simple mechanical lever (I don't says this negatively, this is well done and not over-engineered)

I already recognized it, I love the simplicity, but I´d like to know how it works (in detail) ;-)

Watch the beginning of this video closely, it becomes quite clear how the lifting works there I think:

About the Camera fps in Cura goes slow because it makes 'snapshoots' from the mmpeg stream. Increasing the milliseconds on cura files you can make Cura to show a faster cam but also it raises the cpu use to almost 20-30%.

Fastest way to check the camera is by just accessing the mmpeg stream address (and it only uses a 5% cpu extra). Is so cool. Also since Cura uses snapshots it could be quite easy to make a series of captures every minute or leas to make cool videos of the prints.

What I lov most is that almost anything is easy to edit and mod.

Ha... so it´s not a nozzle switch, it's just lowering the support nozzle?
The AA stays in place, the BB is (I read somewhere 2mm) lowered so it'S lower than the AA, when switching back to AA it's moved up by some mm...
Maybe similar to a pen mechanism..
This is probably compensated by the Z-movement ?
Nice...
So the question is, what are the differences of the AA and BB core...?
