CNC Auto Tool Setting Mach3

Here it enables "Auto tool zero" switch of Mach3 using a macro for setting up the spindle to Edge or Center of the work piece . Work piece can be either rectangle, square, disc or tube etc.Usual touch probe is used as the edge and surface sensor. Circle center macro downloaded from internet is being modified for the shown 4 options by one of my friend software engineer Mr. Manoj. This works perfect ... and I am going to do automatic probe movement ( downward for probing and upward to home after probing) using a small stepper motor assembly on Z axis. ( similar to DATRON CNC) The fifth axis pins in Mach3 will be used for it. Thank You for watching
