The RAMPS shield burned up because the $20 knockoff shields don't use sufficient connectors or copper weight on their boards. We see this quite often in #reprap and I always advise people not go cheap on the board. Ultimachine ramps cost a lot more for a reason...they don't catch fire...and if there was any issues johhnyr would make it right.

I like this. I'm buying an xcarve [1] this summer and have a few ideas in development to build large scale items from inter-locking parts. This kind of 3d imaginative thinking will be required for the first few years of hobby CAM.

Inspiring projects like this should help bring people into the fold.

How'd you make a software which turns a 3D object - with maybe some constraints on geometry - into a set of smaller, printable interlocked parts?
