I've now started the second version of my 2.5D CNC milling machine (many thanks to Gary's advice on parts) - I've got 10 days to build it (holiday from work). The basics are designed, but there's a lot of flexible design involved (i.e. "make it up as I go along" :) ).

I'll be (hopefully) updating my website every evening with the activities of the day.
