Yep, I normally make my bodies 1/32 oversize in thickness and run both sides through the drum sander to clean up the pencil, any snipe, and stray mill marks. I don't think the shapeoko2 has a tool setting input on the arduino, but that would be nice to make the whole depth setting easier. One of the guys at TDPRI is putting together an Openbuilds Ox...and that looks pretty nice too.

Unless I'm misunderstanding what you mean by depth setting, it is possible (I have done this, though it does require updating the grbl firmware on the Arduino) to zero the Z-axis with a touch probe (drive the Z down, until the probe 5V is drawn down to the (grounded) bit). I use an 0.030" feeler gauge and set the Z position to 0.030", after running the probe routine.

Here is an inlay workflow, on a ShapeOko. He does the drum sanding at about 10:25...

I have a dedicated touch probe for Mach on my other router. I didn't think I saw an input on the Gshield for one...... Maybe I'll take another look at them, since it is incredibly useful.
