Testing Various Snapping Connectors
Lasercutters are nice but they are essentially 2D. Using OpenSCAD I'm exploring the world of snapping polymers of printed objects.

Also note the matching warning sign that I found at: lifeboat.com/ex/warning.signs.for.tomorrow

New RepRap Extruder Design
Although we used our RepRaps a lot in recent times we have not done too much reprap research recently. This is about to change!

Because I want to try out the PLA Adrian sent us (thanks!) I need a new extruder which I want to build with parts I have available here. We use RB-35 motors because they are cheaply available here but they have a different mount than the steppers which are used in the ingenious Mendel extruder design which I used as inspiration. But I changed the way the insulator part is mounted since I like our T-slot mount very much. It is very stable and I don't want to glue the insulator like in the Mendel design since I'd like to be able to take it apart.

As you can see in the screenshot I model the extruder in OpenSCAD openscad.org. OpenSCAD is a very cool parametric solid 3D CAD modeller. If you like programming and 3D printing you should have a look at OpenSCAD since it is more like writing code than juggling triangles and vertices like in Blender.

This cover protects the power button which gets easily pressed by accident. It was modelled for the LED Lenser P7 but it can be adapted by changing the parameters.

This was modeled and printed at HAR 2009 at the Metalab Leiwandville with our Giraffe-Makerbot.

New Makerbot: "The Giraffe" printing
Today with the great help of Steffi and Antifuchs I finished Makerbot Nr. 42 aka "The Giraffe"!

Here it prints its first object.

It already printed a first test object and it works!

Temporarily attached CPU fan
Since the Makerbot prints significantly faster than our old CNC-based reprap setup and the firmware already has a command for turning cooling on and off (on=M106, off=M107), I taped on an old CPU fan to see if build quality improved.

Nophead's utility meter key with and without cooling
Build quality improvement by adding cooling.
The left object was printed with the default Makerbot setup (i.e. default layer size, feedrates, filament feed etc.) with no cooling.
The right one uses the exact same parameters, but with the cooling fan running during the entire print.
I was really amazed by the difference - I guess this setup will be permanent from now on :)

Kali - second print
Parameters tuned and our first test object came out quite nicely. Had to switch to black ABS for the occasion.

Something went wrong with Skeinforge combined with wrong machines.xml settings for the V2.3 stepper motor drivers.

Reprap Action Car @ Noisebridge
We donated our reprapped action car to C-Base for their fund raising auction during 25c3. We had no idea who actually bought it until we stumbled across it sitting in a showcase at Noisebridge when Philipp and I visited them in SF.

Nice :)

New Makerbot X-Y carriage with old McWire carriage #2
The young are so bright and shiny, but the old one built from stainless steel and aluminum just chuckles at how brittle the young ones are today.

First extrusion!
After hours of debugging, culminating in finding an invisible solder bridge on the avr chip, we finally reached extrusion on our first extruder. The second one is being built as we speak.
