Since this is my project feed, I get to digress a bit. This little machine has a lot of potential to fill several maker needs. A future project will look at making this machine either mill PCBs or at least apply etch resist. The Portrait and Cameo both have an optical sensor which can see registration marks on the material to ensure precise location of the pattern on the material. This would be very useful for doing double-sided boards.
If anybody has any future ideas for upgrades, let me know and perhaps I will take it up as another project since I would like to get the max use out of this machine.
At some point in the future, I will likely delve into reverse engineering some of it and possibly writing some custom software to control it. For now, it can be controlled through Inkscape. And of course it comes with software from the manufacturer that is also pretty decent, but more directed at crafts.
