My P3Steel Raffaello finished and printing.
I am grateful to Irobri for his awesome design of this Prusa i3 variant which allowed me to get started in the 3D printing universe.
I have been printing parts in red PLA for a couple of months on it now (including all the red parts for the printer itself that one can see in the first picture above) until my first 1kg spool was finished, and I just got started on the blue PLA spool.
I am using an ATX power supply which I modified specifically for this application and an OctoPrint host based on an Android TV set top box running Ubuntu 14.04 armhf.
A video of the P3Steel printing a PLA part can be found here: http://youtu.be/ck8YIkFWEYg
I am documenting my P3Steel build in the reprap.org wiki.
