I am totally lazy-webbing
this for you, its the first hit on google for SCAL2:
Considering it supports US Cutter machines and imports SVG that might be a good alternative to the USCutter provided software offerings. I dont much care for the design capabilities in any of these packages, I just want a cutter driver that doesn't cost $500. Inkscape can emit the SVG files so there is no need for an expensive package unless you have a business.
