It appears that using a touch plate for the z-axis on a Shapeoko 3 requires entering a command-line in CarbideMotion, at least based on a video I've found on youtube. Is that the best method? I could always program a macro on a key of the keyboard, just want to make sure I'm not making this more difficult than need be.
Also, in reading through the FAQ section I found a "Working with Homing" doc which says (a couple of times) to touch-off the material for the Z-axis. What are they actually suggesting here? Do users lower the bit until it touches the material and won't go any further?
I'll tell you what I do now: I have some brass setup bars. I'll use a 1/2" (12.7-MM) bar and I will lower the Z-axis until the bit is about 8 or 10-MM from the workpiece. With my setup bar on my material and pressed against the bit, I slowly start raising the bit until my setup bar is able to slip under the bit.
How do you guys set your Z?
