I have been tricking out my LMS mini mill. I knew the new servo drives had a port for a tachometer but the budget couldn't justify the cost. I did some research and found a guy at cnczone that had hacked the serial string and provided Ardiuno code to decode the string and drive an LCD.
I decided to copy his effort.

Prototype:

It works:

Circuit board for micro controller and cable to display:

Enclosure with display:

I tested with an auduino UNO but as soon as a nano arrives that will be controller that mounts on the pc board

Nice job. Are you going to machine an enclosure for it with the mill?

I envy you guys with the electrical and programming knowledge like this. I've just never been able to "get it". Wish I had a good and patient teacher, or even knew where to start to learn on my own.
