Piezo sensors have been around for a long time. (pretty sure Creality uses them in the K1 series under the bed, for instance) They have problems just like any other solution. The main problem with Piezo systems is that fundamentally you are using an analog signal and converting it to a digital on/off switch. Piezo signals are very noisy, like, motor vibration can read as 'triggering' them, noisy. The challenge is determining what is the exact signal from the piezo system that you want to trigger your 'switch'. So you use lots of filtering of the analog signal to limit the noise. This heavy filtering makes false positives and failures to detect the real signal, really common.
How well this works will depend on how good their electronics are and if their recommended homing practices like changing motor current work well enough.
What we really need is for the system to be integrated into klipper instead of a standalone board that has no clue what the rest of the system is doing and just emulates a switch.

Finally back in stock so have one now. This has the potential of being a better Revo solution than klicky, beacon or tap because it is simple, lightweight and uses the actual nozzle. Piezo sensors have been around a long time, we used them for measuring scientific data many decades ago, they are very sensitive and accurate but require good filtering and signal processing which is what the PCB is for. One thing to note is this is a 5V board, 24V will destroy it so take care and be certain that the voltage is correct.

Easy answer. Install it like a drop in replacement into your Voron (2.4) like E3d intended, and compare it to tap and klicky. That's all anyone wants to see. You CAN connect it to one of your toolhead board endstop goio headers. The long-ass wire is only for configuration. Doesn't need a usb cable like beacon contact, nor a uart/spi header on your tool board. That's why its an exciting offering. The promise here is: lightweight, affordable, simple, reliable, perfect 1st layers.

As far as I know, the first use of piezoelectric elements for bed leveling was by Njål Brekke in February 2015. I copied his idea and put it on the RepRap forum in March 2016 and Moriquendi and DjDemonD picked this up and ran with it as Precision Piezo. Underbed piezo sensors are used in Bambu printers, in the toolhead of BCN3d printers and in several other makes.

Piezos on the hotend to use the nozzle as a probe has been a thing since at least 2016, I remember back then on the reprap forum people messing around with trying to drill holes into piezos and eventually getting it working like that and turning it into a product (precisionpiezo)

Of course it was never as slick as this e3d one because the precision piezo was designed to be somewhat universal for the typical groovemount interface that was the standard back then.

There was also a variant of it to move the sensing to the bed, to replace FSRs which was a popular setup on delta printers.

So both nozzle mounted and bed mounted probing with piezos has been a thing long before bambu and co.

😩 i need to see the result, when is it comming? :D is it going to be better then the cnc tap?

[jameslee]

I say whichever one is ready to go with hotend set up . Don't touch #8 Happy Spouse is a HAPPY HOUSE!!

FYI it's LAYERINGITUP from the discord didn't want to be cryptic, HAPPY ANNIVERSARY!! You 2 love BIRDS!!

There was a guy talking about using pz a while back at one of the digital reprap festivals. I think the idea has been around for a while. There sure is alot of abl choice now adays. Seems to be a vast area. Personally i think theres not a one size fits all aproch so the choice is good

[oOWaschBaerOo]

btw klicky also exists as a nozzle probe, its called Klicky-00 and Klicky-00 Buckshot

[joescalon]

If I’m not mistaken, similar device is used on the A1 and it’s sensitive enough to adjust flow ratio. I really should change my printer over to revo.

I vote watermelon. Happy third anniversary.

US20140117575A1 patent says basically, dont put force detection in the extruder...

[xXPZZAxDMONXx]

now i have zero experience with DJI mics. but they do NOT sound like that. idk whats going on but it sounds worse than an xbox mic. idk. something is wrong with it i think.

[AronsTube]

With a 60C limit I would say no. I'll stick with Beacon.

[Mrs.LeeMerieD]

Just not on my baby lol It works too good 😂 Put it on the watermelon Voron #8
