Re: Digital Caliper as a Digital Readout on Small Mill
Our machinist was talking about doing this on his z-axis of his home machine. So, it must be a pretty good idea.

You should be able to do a google search and find a "home machinist" list that gives detailed instructions on how to do this.

Some things to watch out for...
1. the caliper will have some backlash. You are not getting an absolute signal. Even though you don't have to worry about the sloppiness in your machine, you do have to worry about the slop in your caliper.

2. get the axes of the caliper and the machine axis aligned as closely as humanly possible. This will probably involve machining the holes on your milling machine and the caliper using someone else's milling machine.
