Well, 7′ total.. 6′ cutting length. If I can get tolerances similar to a dovetail jig I’ll be happy. I’m hoping to do hidden finger tendons and other fancy stuff on here: http://mkmra2.blogspot.com/2014/08/cnc-cut-wood-joinery.html

Z travel is 4″ right now.. Thinking of dropping it to 2″ or even 1″ and getting some carbon fiber tubes to help with the weight.

That’s kinda what I was afraid of regarding the bit load.. I’ve never used a CNC before, so a bit of this is me finding out how the cutting aspect works. My hope is that having the other axis be shorter (4′ total, 3′ cutting area) would mitigate some of the flex issues.
