Hi all,
I am getting ready to give my bridgeport clone the DROs it deserves.
it is a fully manual Mill, (NO Powerfeeds)
I am wondering what might be the best setup for hardware if I was only interested in DRO functionality.
what considerations are there when choosing between Rotary Encoders and say Glass Scales or other?
also what are people using to monitor there spindle speeds?

I would think linear scales are the only thing that makes sense with ACME threads and their large backlash
A single proximity switch should be adequate to measure spindle speed if there's a convenient place to mount it

Probably glass scales and an Arduino. LinuxCNC seems overkill.
It might make more sense just to get a commercial DRO kit.

hey guys, thanks for the replys
this is just a prof of concept for me, I have much bigger plans of standardizing the interface of all the machines in my shop.
this would just be a stepping off point.
I am currently building a plasma table that I plan to run LinuxCNC on.
you guys are totally correct about the scales I'm just being cheep.
as for spindle monitoring, I guess just an optical sensor is all people are using?
Thanks

That will depend on the application. Some use a single opto or a proximity sensor watching a gear. My machines both use resolvers on the spindle. Some people end up using super-high precision encoders (like the Heidenhain ROD). It rather depends on the application.
