Touch Probe and V-Bit

1

I had a dilemma the other day : My carve started out with a V-Bit and as I brought the spindle over to the Touch Probe I realized I did not know what value to use for the diameter. To avoid the issue I changed the carve tool path so 1/4 inch end mill was first. Am I missing something with the V-Bit, any other suggestions on what diameter to use for a V-Bit when measuring XYZ? TIA!!

Your solution was correct. Always use a straight bit to determine your XY origin.

Though, you can always find the origin with a straight endmill, then swap to a v-bit and probe Z, if you’re running a v-carve only toolpath.

I am learning slowly, I give myself credit this time though since something didn’t look right when I tried to do the xy with the v-bit. Thanks Dan for the details here !!!
