Re: Homebrew DRO system

Matt,
A CNC retrofit and a DRO on the same machine is kind of redundant.
You can save several hundred bucks on the DRO and just put it into the
CNC up-fit. Once you have CNC, you have DRO.

Linear (glass scales) start at about 200 bucks (4 inch) and go up from
there. The cheap way to DRO is to use surplus quadrature (rotary)
encoders and either the Kaluga/Mauch DRO or the free Lindsay DRO.
Both are PC based. The 80$ kit from Camtronics does not include
encoders. It is a KIT to build a board (ISA, I think) which goes in
your PC. The Lindsay DRO uses the parallel port.

The only reason I can see to do both would be if you don't plan on
having the CNC in place for awhile, or you just want to learn, or
build your own DRO

Luck
