[chbot] building CNC router - was Free stepper motors

[Chris Hellyar]

Hi-ho,

I've done a bit of work on CNC control systems in the past, and have 
been interested in a hobby sense since about 2005 when I retro-fitted by 
Lathe.  (Which I sold... I regret that now, long story)

Back in '08 built the 'junk box' cnc router, and I'm currently planning 
a much larger router buy/build project.  (buy vs build depending on how 
much money the bank will lend me!)

The build thread for my junker is on cnczone here which has a lot of the 
gruesome details:

I've done some PCB drilling with the small router, but never got around 
to trying routing a board.  The main output from it has been dolls 
furniture and dinosaur skeletons :-).

Cheers, Me.
