RE: [CAD_CAM_EDM_DRO] Tapping into the group knowledge - DRO

Dan Mauch of Camtronics has sent me some pictures of a mounting system he
put together. I put them on my website at
http://www.ktmarketing.com/CNC.html then select "Pictures of Dan Mauch's
Linear Encoder mount system". It is the 12th link down from the top.

Dan also sells a nice kit to handle the electronics part of a DRO and it
includes the software. It is also the card that would be used if you wanted
to use EMC as a closed loop stepper system.
