Did you modified the original Hypercube carriage? I'm interested in moving my piezo from the groovemount to the carriage, but I didn't have time yet to do the modifications to make room for the piezo...
Cheers

Looks right to me. If you can set low motor current - do so for safety. Then get the bed way down low, send a G30 and tap, make sure the bed stops moving when you tap. If that works, then send G30 and leave the nozzle to contact the bed. If that works - you're done - probe away!
#define Z_MIN_ENDSTOP_INVERTING false #define Z_MIN_PROBE_ENDSTOP_INVERTING false
Probe failed.

What type of printer is it? It might be too sensitive yes. Show us a photo of your machine and a closeup of the piezo sensor.

Okay so when the machine is at rest and you send m119 you get - open?

What happens if you send m119 whilst repeatedly tapping the nozzle upwards?

For tuning turn VR2 to the point where the LED just goes out. Thats the most sensitive. If you want a bit less turn VR2 slightly further and just test by tapping by hand to see what effect it has.
If its way too sensitive, when the bed lowers the vibrations through the frame trigger it.

Please excuse my lack of punctuation I'm dictating this I think the problem is with end stop pull-ups being enabled if possible change your firmware configuration so that you disable end stop pull up for the Z min
//#define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors #if DISABLED(ENDSTOPPULLUPS) // fine endstop settings: Individual pullups. will be ignored if ENDSTOPPULLUPS is defined //#define ENDSTOPPULLUP_XMAX //#define ENDSTOPPULLUP_YMAX //#define ENDSTOPPULLUP_ZMAX #define ENDSTOPPULLUP_XMIN #define ENDSTOPPULLUP_YMIN //#define ENDSTOPPULLUP_ZMIN //#define ENDSTOPPULLUP_ZMIN_PROBE #endif

I'm a bit stumped here can you verify the signal wire between piezo pcb and your controller is unbroken? I can't think of what else is going on.
