Airbus E-Fan | Fully Charged
It was a great privilege to witness the takeoff of the amazing little Airbus E-Fan.
This diminutive electric plane marks the start of something much bigger, Airbus' plans to build full size hybrid electric passenger planes.

That also applies to jihadis suicide bombers spashed on the front page of the BBC, with ISIS flag in the background doing a 'V' for victory. WTF are they thinking?!?!

3DBenchy testprint with Woodfill and 0.5mm nozzle. Thanks to woodfill the printtime was three hours instead of the usual 1h. Since this is the first Woodfill print on this machine the calibration isn't good, still the first wooden benchy i have seen :)

Since it has only 30% infill, yes, but swimming? No!

Quality is okayish now, mostly the flowrate is still a bit off.

Another testprint with the new printhead. Quality is ok this time, though the flowrate is not yet what it should be.
Sliced with Slic3r 1.2.6 Beta at a speed of 120mm/s for perimeters (external @50%), 120mm/s for infill and 50mm/s for bridges. 0.3mm layerheight,

Printing elastic filament
I just want to share what i tried so far and get your input on what worked for you and what not.
I think everyone who ever tried printing elastic material came to the point where you realize that the most important part is the guidance of the filament after the bolt. There are a couple of solutions for this and i tried a few of them.
At first i tried to modify a wade extruder, but the idler / bolt diameter mismatch made it difficult. Inserting a PTFE tube in the lower part of the wade made things better, but was still not really reliable enough for me.
From 10 points i would give it a 4

Then i tried my hand at creating a bowden extruder for elastic filament and to my surprise it worked rather well. The  final design i ended up with was my Compacto extruder. The PTFE bowden tube went through the complete extruder and had a hole on each side for the bolt and the idler. 
http://www.thingiverse.com/thing:336444
The extruder worked totally reliable but was a PITA to load and unload. Also it was impossible to create a direct drive version of it.
For that it gets 8/10 from me.
Here are some earlier versions

After that i came over a friends design, the TinyFlex
http://www.thingiverse.com/thing:615465
While i liked it a lot and it simply works, i did not like the mounting though. So again 8/10.
Thomas and i created a NEMA 14 variation
http://www.thingiverse.com/thing:643582
Of course it will only do 1.75mm filament, but it will easily cope with high print speeds (>100mm/s).
From that i derived  the TinyFlex V, which offers a V Mount and can be mounted left or right sided (for dual or dual X carriage use).

That one is not fully finished yet so the design files are not online.
So far i give it 9/10

So what did you try? What did work, what did not?

After a bit of calibration things look much better (middle and left)m but now i'm out of woodfill.

Seit vielen Jahren sind wir Firmenkunde bei CU und als IT Verantwortlicher kaufe ich dort gerne weil die Preise ok sind, die Lieferfristen stimmen und im Bedarfsfall auch die Beratung sehr gut ist. Seit einiger Zeit ist aber die Rechnungsstellung und Abwicklung durch CU nicht mehr als mangelhaft zu beschreiben. Es vergeht keine Woche in der unsere Buchhaltung nicht nachfragen muss um ungerechtfertigte Mahnungen zu klären, nicht zugesandte Rechnungen anzufordern etc. Persönliche Beschwerden in dieser Sache sind immer wieder nett nickend zu Kentniss genommen worden, geändert hat sich leider nichts. Die schlimmste Erfahrung war als CU einfach und ohne Benachrichtigung die Kundennummer und damit die Rechnungsbedingungen geändert hat. Dringende Bestellungen wurden nicht ausgeliefert sondern zurückgehalten da wir als langjähriger Kunde (>10 Jahre) plötzlich als Neukunde eingestuft wurden. Es wird für mich immer schwerer meinen Chefs gegenüber zu begründen warum wir noch bei CU einkaufen.
