I just used the one that is in the shopbot files
Honestly I think that's what I did too, I just modded mine a bit.
Shoot for leaving a 1 to 1.5" border around all zones and 1" squares. If it's +/- 1/8"-1/4" one way or another, no big deal.
Use a down cut spiral to put the grooves in as it will reduce the chance of chipping out the squares. Lesser quality MDF with an upcut often chips out.
Extra points if you dance to the tune the machine plays while cutting the grid

thanks guys. The shopbot guide indicates a 1/2" diameter bit for cutting the grid, did I read that right?
