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 Arduino 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 LCD display:
Enclosure with display:
I tested with an arduino UNO but as soon as a nano arrives that will be controller that mounts on the pc board
