Welcome to RawCNC

 

Raw is a DIY CNC machine that anyone can build with parts from us or others. There is many similar machines and they are all good, but if you want to use your machine professionally you need to make it stronger and that’s the whole purpose with the Raw project. For our Swedish visitors you can visit www.cncmaskiner.org if you like.
