Cube 3D printer community

Well it appears this is going to be more of a journey rather than a quick hack.  I've now discovered why 3D Systems used a 24v power supply for this sucker...Because the hotend wont heat beyond 215 degrees with just 12v.  Sooo this means I now need to reconsider the system. Basically I could change to a more suitable hotend for the power, OR change to a more suitable Arduino for the power. The Mega 2560 Runs on up to 20v, so... while im confident more power will sort the problem, I'd rather not run this puppy at 20v due to the fact this is a limit, not recommendation.

I've got a feeling this unit will require the addition of a J-head, cartridge style hotend which runs well on 12v, unless I can figure out how to get the Cube hotend to do more with less. 

Sigh.
