I moved this message from CAD CAM EDM DRO to emc-at-nist.gov
to give the non EMC'ers a break.

How hard would it be to change the motion modules to watch a
kluga/mauch encoder board for an encoder input. Now that would
nice, to select an axis and spin a panel encoder wheel while in
manual mode to move the axis's. And possibly put a command in
to switch from 1X, 10X, 100X. so using a 1000 line encoder in
1X you can get very fine movements and in 100X you can get
some speed out of it. I think jon elson was thinking of that for
his boards.
