@CodeBuster,
Sorry if I appeared to ignore your question, I didn't intend to. Have I talked with you about this issue on another platform? It can be hard matching up email addresses and forum names so forgive me if we've already covered some of this.
Unfortunately I have no experience with Repetier firmware so I'm afraid all I can do is run through verifying with you that the output of the Piezo board is as expected. Hopefully, other people with more experience of Repetier will be able to help you with the firmware setup.
With the pullup enabled, measure the voltage of the pin on the RAMBo, without the piezo PCB plugged in, should be 5v
Plug in the Piezo PCB, red LED on, measure the voltage of the SIG pin on the piezo PCB, should be 5v
Turn VR2 to illuminate the blue LED, measure the voltage of the SIG pin, should be 0v (or very close)
Turn VR2 back to illuminate the red LED, tap the piezo and check for blue LED flash.
If you can, measure the voltage of the SIG pin while tapping the piezo, you should see some reaction but it may not reach 0v as multimeters typically measure quite slowly and the output pulse is quite brief.
If all these things are responding as expected then you have a configuration/firmware issue, I wish I could help more with that but I've never used Repetier.#

I see in the Arduino documents that what you say is true. On a 5v atmega2560 anything above 3V on a pin is registered as the pin being high.

Although 3.5v is theoretically marginal it hasn't caused issues in the past and it's unlikely that a level shifter would help. Later versions don't have this issue.

I have rechecked Printer::runZProbe and saw 3 places where a delay might be needed for safe signals. Will update the dev version later today along with an other addition I'm testing.
