in mid august I got most of the parts printed from a friend on an commercial 3D-printer ... two weeks later I nearly finished my first darwin.

but still some problems need to be solved before I am able to print. first of all I couldn't find capa in austria for the toothed wheels.
the small ones I could make with the lathe, but the bigger ones have 62 teeth, which goes beyond the possibilities of the lathe, which can only handle 60 ... one way out was to order "friendly plastic" from germany (www.quiltzauberei.de). In the online-shop they tell you its colored, but what you get is almost black. only one side of the surface is colored. anyhow, after melting it the color appears to be mixed with black. well, the question of esthetics beside, the wheels seem to be good.

The second problem is the firmware. I have been getting strange messages during heating up the extruder, so I try to improve the firmware as a next step.

the sync of the steppermotors also causes problems.

Just thought I'd say that the number of teeth for the Z axix is arbitrarily big. As long as the contact surface with the belt is big enough to provide the grip... 60 teeth should easily suffice.

Nice to see another Darwin kicking around!
