It is always satisfying to find more uses for projects. I guess that's because so many of them just end up on a shelf collecting dust, not that that will likely happen to this tool.

I am working on a stargate for the sci-fi contest (shameless plug for our entry) and was faced with the task of carving lots of tiny details into thin, flat plastic. What an ideal task for this mill. I drew up some svg images of the stargate details and tried milling them into some 1.2mm polypropylene sheet. Here are some of the results.

It was a great success. It also led to several significant software changes listed below.

• Cut depth is adjustable on the fly via the processing sketch.
• All important parameters on the controller can be set via processing.
• The math was rewritten to solve some accuracy bugs and be more efficient.

The updated code is in the usual places:

• SVGMill.ino (arduino code)
• SVGReader2.pde (processing code)
