Underbed sensing is really only suitable for stationary beds (think Delta's). You can always put a piezo between the carriage and hotend assembly.
Works flawlessly on my P3 steel :
Suitable ? How ?.
For Delta, DC42 has a neat solution, a Wheastone bridge of strain gauges integrated in the effector.

Hi MKSA,
I don't understand your comment?
I was only saying that underbed piezo sensing is very difficult on a moving bed. (And it seems leadinglights might have a solution for that )
I know the smart effector but that was not my point...

I really, really love the idea of being able to use the piezo since it essentially uses the nozzle tip as a probe. This technique seems to be praised as being the 'best' solution so far on many different blogs. There is one thing I'm mainly interested in, and that is: are there good effectors for Delta printers available that make use of this piezo technique? I am interested in the latest Orion module but I'm having difficulty with the implementation of the part.
Honestly, I think a custom effector carriage would be better than designing a carriage that would allow to fit the Orion probe being sold 'as is'. Are there any files available from which I can pull the sizes for such a carriage so I can design my own and is the warranty void when I put the piezo module into my custom designed effector?

I have two deltas with Piezos as under bed sensors. Work perfectly since more than two years

There were area's that would spike up and move around with multiple probe attempts. I have been tweaking and getting those reduced. I finally finished designing new fan guides that will also hold the BL Touch so I can compare probing system's map results.
I too see odd bumps and stuff. Not only that but there are odd patterns to the bumps. In any case, please be sure to post your results of the BlTouch comparison. I am very much looking forward to those comparisons.
I have attached a screen shot of my height map.

I see so many solutions. Right now I have ordered a piezoelectric disc that you can mount temporarily under the tip of the hotend. My idea is to do a really good bed leveling program and then save the mesh because the delta shouldn't really change much in between prints. When it's done I can take off the disc and just print without it. I'll probably have to level it every once in a while but for me this feels like the best solution.

Can you elaborate how this mount would look like ?

The amount of movement of the nozzle should be very very small, less than one microstep. If your nozzle has more movement than than then something is wrong.
Any mechanical nozzle probe technology is going to require dome degree of movement of the nozzle, the Orion PCB and mounting parts are designed to minimise this, I have not seen any system that uses the nozzle as the probe that has less movement than piezos.

@Ohmarinus,
That's not actually a piezo sensor at all, it's an FSR, a force sensitive resistor, they are much more delicate than piezo disks and not as accurate.
