Hi Billy,
once you've got your machine to the point that it will faithfully follow the G code it is given, and it sounds like you are close, the 'real'
work of CNC begins.
If there is anything like 'creative' work of genuine skill and experience its crafting the G code for your machine to 'digest'. You may get away buying a cheap Chinese
router but if you expect poor CAD/CAM software to produce acceptable results you're dreaming. Amongst the skills that you'll need to acquire is to be able to read
small sections of G code and understand what the machine will do when it encounters it.
