No but it appears to use standard positioning technology like CNCs use. I ran an SCM CNC beam saw for a little while once and it was accurate to 1mm while cutting up to 7 layers of 5/8" melamine at a time. Probably using similar technology.

I'm with David on the fact that my Unifence scale is accurate enough but one of the other things I didn't care for in this setup is the power cable going into the end of the fence. I can't figure out why he didn't go with a ribbon cable that folds and unfolds as the fence moves that would hang below the fence rail.
