pause at 0.4sec

You can and should also set pause before probing

Hi yes its certainly possible. If you redesign those parts to allow space for a piezo to sit in the bracket, so that any downward force will squeeze it, then it should work. Its easy enough to experiment on the bench if you have our PCB, or have made your own amplifier circuit. Just tap the part with the piezo in it lightly and see if you get triggers. Generally with underbed its very sensitive as there are 3 or 4 piezos contributing to the signal.
For probing with a moving bed in y axis, youll need to use the "pause before probing" setting in your firmware, 0.4sec is usually enough just to allow the bed to come to rest, before each probing dive takes place, the lateral movement of the bed will trigger the z-probe, but so long as you pause briefly before each probe it doesnt matter.
Interested to see how you get on/help, since we don't currently have a solution for i3 style machines, especially the original prusa, maybe it can be adapted under the bed there too.

I have a wanhao i3, and (once I get my new printer working properly) I'm planning on experimenting with a mount that sits between the X rails and the z carriage. On mine (which might be unique or typical, really not sure) there is enough compliance in that joint to trigger a piezo.Quote

Took off the motor and the filament guide part and this is how it looks. I guess technically i may be able to put the sensor somewhere at the black backplate that holds the extruder setup to the x carriage but its quite sturdy setup so i am not sure what good that would do since i don't think the motor would press against the sensor at all when the nozzle touches the plate. I could be mistaken tough but that is my initial reaction looking at this.

We are working on a version that does not require manual tuning but it's not a small task.
I'm sorry the board isn't working as it should, can you just confirm that it's the v1.21 board that doesn't work?
My first suggestion would be to check that the wires are soldered onto the piezo properly and that the piezo has no cracks in it.
Are you testing by tapping the piezo directly or is it in a mount/printer?
If you have a spare piezo try that.
Try tuning VR2 as close as possible to the point where the led turns on.
Try turning VR1 gently left and right a little before putting it back in the middle.
