We have new printer and I have to say awesome one. ShaperCube. It’s completly made of Aluminium. You can see few pictures of printer at his creators flickr. Joachim Glauche’s flickr.
Machine is using Arduino Mega as main board controlling Stepper Boards 1.2 and DC board which is controlling extruder etc.
Btw. we are first who ever build ShaperCube :-)
