Vince did away with the encoder chip and wired eight Hall sensors and output wires to a PLC. The only down side is that four more wires need to be routed. I used HAL components to decode my 4 bit turret position so you would save on the decoder with the four extra wires. You could save a bunch of wires with a PIC and SPI link mounted in the carriage to handle the turret and limit functions. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
