One of the (several) CNC craftsmen I follow on Youtube said something in passing…that he didn’t use his probe to set Z with his sharpest tapered vbits because “the tip is just too delicate for a metal probe.”
Although I’ve only used a 60 deg vbit as of yet, I am planning some tiny text carvings that will use a 22.5 or sharper angle. I would have thought carbide bit vs aluminum probe would not be an issue…anyone here ever damaged a bit while probing (when the controller is running the probe, I know people manually run bits into probes all the time)??
I’m using the paper method for sharper bits. I’m having issues with the probe anyway but I’ve found so far that the v bits don’t seem to register as well. About 30 percent of the time it will “see” it when i do the initial test then when it is moving it self down to do the calibration it doesn’t register and keeps driving into the probe until I stop it. Makes me nervous so I just do the paper method.
In terms of which is stronger, it’s most likely the bit. Aluminum is pretty soft metal. But I’d rather not damage a $60-$100 bit testing that out.
