    Adding A Tool Touch Off to my Centroid Acorn CNC System

    This article describes how I connected a Tool Touch Off to my Centroid Acorn CNC System.

    If none of this statement makes sense to you, let me explain a little. A Tool Touch Off is a fancy electrical switch. In its "normal" state, the switch is closed. When a disk on the top of the device is depressed a tiny amount, the switch opens. This switch is connected to my Centroid Acorn brand Computer Numerical Control system.

    As configured, I install my various cutters one at a time in the mill and push a few buttons. The system lowers each cutter down on my Tool Touch Off and can sense touch down. This lets it measure the length of each cutter. It can then compensates for the variation in cutter length as machining automatically proceeds.

    Thanks for this Rick. I'm about to start investigating and building a CNC so will look at this with interest.
