New idea for Z probing?

I see one of the newer trends is to use a piezo sensor mounted to the hot end mount. Why not mount a piezo under each of the build plate corner mounts? Their pretty inexpensive so using 3 or 4 vs 1 is not going to break the bank. Wouldnt that be easier and sort of universal rather than having to engineer a way to mount a piezo into the hot end mount? Dont know, just an idea. Maybe somebody already tried it.

Good idea otherwise though

If you look at the page selling the piezo sensors you will find they started out with that idea. Then they found it much easier to mount a single sensor on the hot end. So your idea is not new and different.

There are advantages and disadvantages to both methods depending on how your printer is set up. We have a dedicated hot end module that has the advantage of requiring little or no modification of the printer, it's designed to be plug and play. We also have kits and parts available for people who want to do something different, whether that's an integrated carriage with piezo sensing or underbed sensing. The primary disadvantage of underbed sensing is that you will almost certainly have to do some reengineering.

There are more polite ways of saying this if you want to avoid the risk of people thinking you're being deliberately rude
