The picservo board reads the encoders (750000 Khz?) with a dedicated pic
chip sends it to the controller chip then closes the loop all on the board.
He sells a chip set for 32 bucks if you want to build your own board. I had
a small servo running in a couple of hours with the included test software.

It is a nice machine, good fit and paint, adjustable bearings on all the
lead screws, seems tight. I am an ME not a machinist and don't have enough
experience to know what it is lacking. I wanted a machine with a knee and
this was the least expensive new machine.
