Hi all,as a beginner to the world of cnc I was all set a few weeks back to buy a Chinese 3040 cnc,I opted to wait and gain more knowledge on here and through a few books etc,now I see the denford on eBay and was wondering is it better than the 3040? I might like to cut some aluminum as well and thought it might be more capable? Its going for 750 complete with computer and software.
