@arhi Thank you! I will take a look at that. I apologize if I didn't say it before, but I am using a Precision Piezo Universal, not an Orion.

Thank you all for replying! Okay, so I finally had some time to take a look at it today.
Unfortunately, the piezo is still requiring about the same amount of high force to trigger the Duet (while in digital mode).
I am starting to think that there may be an issue with the way that the hotend/extruder is connected to the piezo mount. When I insert the piezo into the mount, it feels like the solder joints are pressing out on the mount, making the hotend assembly have to use even more force to bend/press the piezo. Could this be the case?
On a somewhat different note, what is the typical resistance or voltage either across VR1 and VR2, or from VR1 or VR2 to ground? (I want to make sure that the pots are set correctly.)

Thanks again for all of your help!

Hi Everyone!
I have been using a BLTouch on my Folgertech FT-5 R2 for awhile now, and I have recently upgraded to a precision piezo universal kit. The piezo is mounted behind the extruder's stepper motor on precision piezo's NEMA 17 mount.
I am running into issues when I go to do a probing move (either issuing G30, or running mesh bed grid compensation). When the nozzle is pressed up (my finger barely touches the bottom of the cold nozzle) the red light on the amplifier board goes off, and the blue light lights up (blue stays lit for about .25 seconds, then goes off), then the red light comes back on. I have both VR1 and VR2 set as high as they can go without constantly triggering.
The trouble is that DWC doesn't register a change (either in analogue or digital mode) until I press up on the nozzle. Hard. (Enough to cause the bed stepper motor to loose steps when moving.) The piezo is connected to the amplifier by wires that are no longer than 100mm.
Any help you all could offer would be greatly appreciated!
