I checked out the JR Kerr web site. Interesting product. I couldn't quite
understand though, does the pic board handle the input from the encoders

or

is that handled by the computer it is attached to?

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.

I was looking at the Grizzly G1004 in the catalog the other day. How long
have you had it? How do you like it? What don't you like about it?

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.

Have you started to convert your machine to NC yet? What are you planning

to

use for your servo motors?

I have to go.

I am very interested in the EMC information here as well as the other
threads ( encoders, vacuum forming etc. ) and would prefer it remain all
mashed together.

I have a small Grizzly knee mill (G1004?), and some pic based servo

boards

from www.jrkerr.com that I am intending to use to move my table.
