I came up with a device for finding the surface height of my material (when bit touches a 1" magnet, it turns on a light). I've been looking for a gcode which I can use to have the bit "SLOWLY"drop until it touches the magnet. I could then use the g00z-1.00 to place the bit on the material surface. What would the code be for ensuring the z goes slow enough to allow me to hit the stop button?
Thanks in advance for the help...
