So I have spent hours trying to get my sensor tuned with no luck. I had initial success when I first set it up but the sensor will either false trigger or push too hard into my bed, I cannot find any middle ground and I am making the most minute adjustments on the pots. I don't know if it's the actual mechanical setup that I have (pics below) or if it's operator error or if it's just the sensor.
Whatever it is, I'm pulling my hair out as I've read and re-read the tuning instructions umpteen times.
I have tried moving the location of the circuit board further away from the motor and that did not help so I am at a loss for what to try next.
I was really wanting to use the Titan Aero which requires the Piezo mount as in the pics below but I'm afraid this setup may not work (it is a beta setup after all).
I may have to go back to the regular E3d V6 hotend, a different carriage mount and the Piezo Orion or abandon it all together and go back to the BLTouch.
Any help would be appreciated as I'm out of things to try:

Do you realize that by having this heavy mass (Titan, hot end ...) hooked up on the piezo, you have just reinvented the piezo vibration/seismic... detector ?
Add to that all the wiring and may be other things that is pulled when Z homing, force that is transmitted to the piezo too !

You could engineer your own mount that reduces the amount of cantilevered mass or you could try underbed sensing which is ideally suited to beds that don't move in Z.

I am not familiar with your machine, but with the hotend fan and the whole gantry moving for a Z home, I see why you have problems. If the HE fan is running, try stopping it when homing - though I have no problem with mine, but my gantry is stopped since the bed moves. Initially, the movement of my gantry during XY home triggered mine even though it didn't start until XY was finished. That is why I needed the delay.
Your gantry is running during homing. It may be possible to play with the pivot tension, trigger sensitivity, and offset. But anything you do there may be self defeating. If the pivot tension is too loose your print will suffer, if it is too tight your homing will suffer. I am totally amazed that mine works where I initially set it. Total SWAG.
Other than that, a bed mounted arrangement seems to be in your future. But that also seems very complicated. If your bed is very flat, I would go with 3 point probing and only execute a home at one of those points.

Currently on that printer, I've got 4 of the Andromeda piezos in the corners. I don't have to adjust the bed screws often, so it's pretty much a "set it and forget it" type thing. It's more trouble to set when it does need to be done, but aside from that, it works great.

Hey guys, I just published my mostly complete electrical design that incorporates an onboard microcontroller for auto-calibration, and an optional version that converts the extruder cablechain into an FFC.
