Clint Branham Video, Acorn Surface Touch Off with Tool Touch off

[cnckeith]

Clint Branham Acorn User video shows how he is using a material surface height detector in conjunction with a tool height detector with his Acorn CNC controller. he says... This is my first CNC video. It is a video of an M6 macro for setting the Z0 to either the top of the part or the top of the spoil board and reference a fixed tool touch off and set subsequent tool changes to that height. It is soooo nice to have macros that just work. Unlike Mach3.
