Quotewhosrdaddy Yes, is working like a charm. Z offset is -0.14 for my setup. The back of the bracket houses a bit space for the piezo. Cool, that's more or less what I've in my "traditional groovemount" setup, so the accuracy/pressure needed seems to be quite similar . Just curious, are you doing the probing with the nozzle cold or hot? I know is better (and recommended by the PrecisionPiezo guby okercho - General
Quotetekkydave okercho - not sure who your question is to, but I'm just using a standard PP20 groovemount at the moment in my D-Bot corexy. The only mod I have made to the electronics is to replace the VR2 pot with a 10-turn one. It's much easier to calibrate now. I wouldn't rcommend this mod unless your soldering skills are up to it. It would be very easy to damage the tracks if you're not veryby okercho - General
Quotewhosrdaddy Tekkydave, just put the piezo between the mount and xcarriage, this results in a more sturdy setup (and you gain some z-height in the process) Thingiverse link I will give it a try in the CoreXY I'm rebuilding, but probably with a Bondtech instead of a Titan, although that should make no difference. Are you getting good results with that setup? What Z Offset you've configured?by okercho - General
My two cents here With my Prusa clone, using a PP20 kit and the Duet, I'm probing at 150mm/min (so 2'5mm/s), as I've found the most reliable results. However, I don't know if it's because the way I tight the screws of the groovemount, my Z offset is bigger than before, I'm using now 0'23 as Offset (for a cold probing, so I'm assuming 0'15 for the piezo bending, taking 0'07 for the nozzle heat exby okercho - General
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 QuoteIsmangil Sanity check: is this configuration for Hypercube X carriage OK? I tapped the carriage and got the blue light.by okercho - General
I would like to volunteer if possible I have one coreXY (with Duet) and one prusa I3 (with ramps + Marlin) with the piezo installed. Cheers QuoteDjDemonD Can I ask for 2 volunteers who have used the Piezo20 module before to beta test a new idea? I'd also like 2 volunteers who have not tried it before. Any takers? I'll send the beta product to you for free. You are welcome to keep it as loby okercho - General
OMG Idris, that´s a lot of manual work! Honestly, I thought that you got from China an almost finished board, not just the PCB... impressive guys! Regards QuoteMoriquendi For anyone who might be interested I've made a video detailing how I make the PCBs, LINK Idrisby okercho - General

QuoteDjDemonD Okercho (and others with bowden issues) - there is a sure fire solution. Design a place above the piezo sensor unit, to screw your bowden coupler into, then run a PTFE tube from the bowden coupler down through the piezo sensor unit into the hotend. This decouples the bowden tube mechanically from the piezo disc. I accept it might not always be easy or neat to do this, but if the bowby okercho - General
QuoteCaptainHero So while i am still trying to Frankenstein my way to a somewhat working hotend mount on my Wanhao I3 i made some progress recently which made me hopefull that there is light at the end of the tunnel however there are a few issues which i can't seem to pinpoint why they keep happening seemingly randomly. So i have made a contraption to have a single piezo being triggered around mby okercho - General
Sorry, I promised this video couple of weeks ago, but I wasn't able to record it until now. As you can see, the 1.22 board is working fine, then I replace the board with the v1.21, and check the resistance (my multimeter fluctuates a lot, but it does the same with the good one, and the values is around 600 when it comes "steady"), then you can see that the led don't blink and that the VR1 is nby okercho - General
QuoteMoriquendi We are working on a version that does not require manual tuning but it's not a small task. I'm sorry the board isn't working as it should, can you just confirm that it's the v1.21 board that doesn't work? My first suggestion would be to check that the wires are soldered onto the piezo properly and that the piezo has no cracks in it. Are you testing by tapping the piezo directlyby okercho - General
I think the new design makes more sense, I had a bit of trouble to find a place to put mine and ensure is fixed and stable. Regarding suggestions, I think I read before that you were thinking about replacing the pots with some kind of digital version, so it will be easier to just "program" it instead of playing around with the pots... I think that would be a really amazing improvement... althougby okercho - General

Just let me know if you want some QA for this, I've a CoreXY with 300x300 bed, and I'm restoring a Prusa i3 with 200x200 bed. RS just sent my piezo disks, I should get them next week. Cheersby okercho - General
Yup, I got some 7BB-20-6L0 ones. Thanks!by okercho - General
No worries, I will get some from RS-Online in Spain, just curious about the frequency . Cheersby okercho - General
Interestingly I'm finding a lot of different piezo disks (different sizes, and frequencies)... I can see in the ones that RS-Online (currently doesn't) have that the frequency is 6'3Khz... How the frequency affects? Regardsby okercho - General
Looking forward to the final implementation for the piezo in the bed for a CoreXY... will this work with big beds? I'm using a 300x300 one, and I'm not sure if just with 3 disks this will work... BTW, I saw in BangGood that they're selling piezo disks, but I'm not sure about the quality... @DjDemond can you recommend a brand/place for buying additional piezo disks? Regardsby okercho - General
Don't worry, I was just curious about the design Cheersby okercho - General
