@topenga If you are in SBC mode (attached RPi), use apt update/upgrade. In standalone mode just upload the web interface ZIP file from here or here.

@zapta the example I linked to is for use where Z hasn't been homed.
and the docks typically have a little lip to stop the probe dropping out although its still a possibility if held upside down at the right angle.
STLs for the V2.4 can be found here

@creamofpantssoup It would be best to start a new thread and provide as much detail as possible including your config files and firmware versions and details of wiring.

@phaedrux
Thanks so much.

Your suggestions of course!, worked well.

Thanks Once again.

@jay_s_uk Thanks a lot

@phil333 this sounds similar to https://forum.duet3d.com/topic/25291/genuine-bltouch-v3-0-weirdness-with-rff-3-3?_=1635272591563 except that you are using a Duet WiFi instead of a Duet Maestro. I will take the fix that I implemented in RRF for the Maestro and port it to the Duet WiFi/Ethernet build.

@brewchester I’m have same problem after updating from RRF 2.2 to 3.3
Can’t hame z.

What solve your problem?

@cosmowave for the moment PETG...

Thx

@jay_s_uk thanking you! Will try that remotely next chance I get.

@paulhew Thanks dude and yeah, I've seen that link and have all those configured. I'll keep sussing around with it

@arhi I understand completely 👍

BTT quality is a nightmare, don't ask me how I know. I wish I had started with RepRap and Duet board two years ago when I picked up the hobby, but then again, I've gotten an extensive education on what doesn't work and a bigger appreciation for what does.

@jens55 on a whim I touched up the solder on the 5v and ground pins on the fan board. Have it running on another pi that's running 2 web cams + a small display and hasn't had an issue yet. I'll test for a couple days. Maybe it was just bad manufacturing.

@leadinglights Thanks for the remark with the Chladni plates! I never heard of these before (not common part of school physics when I was a pupil at least), but this fits perfectly to what I observed with my oscilloscope.

Since my Neo print head would need complete redesign to include a piezo up there, I stuck with reading out the sensors that got crosstalk separately and am quite happy with the result. I see some repeatable measurement errors due to the varying flexibility of the print bed, but that is fine for me for now.

Hm... now that I think of it, it might be worth a feature request to be able to substract a given height map from a newly measured one... by doing this you could remove such measurement errors...

@snt if the Duet3 has an heater3 on gpio, you can use:

M950 S1 C"exp.heater3" ; assign GPIO port 1 to heater3 on expansion connector, servo mode

@engikeneer You are right that could be a good opportunity. I'd have to check clearance really well but if people are interested it can be done 🙂

@fma said in Texture mapping with feltpen carousel?:

I plan to make tests with pens, as Make Anything did; it is a very easy setup...

I already figured out, only 'permanent markers' stick to PLA.
I think, I've seen the video and their process is not able to produce real textures.
You'd have to dye the filament with a timed process. I'd better like to steal the mapping algorhythm from "velocity printing" and rewrite it to add ink layer by layer.
I don't expect perfect results, but a powder printer with inkjet is a bit above my budget..Let's see how bad it is..

@lui2004 Ah, sorry, I misunderstood. Contact Precision Piezo. According to this page https://www.precisionpiezo.co.uk/product-page/precision-piezo-orion-kit

I guess, it's not speed but acceleration one has to think about - then It is clearer, at least for me 🙂

Yesterday, I tried how a piezo speaker I had lying around might react by gluing one onto the frame holding my printbed, roughly where the Andromeda would be mounted if I followed my initial idea. It turned out my spings are too stiff: the bed spring would rather bend the frame if I pressed onto the bed instead of giving in - and the piezo would barely detect anything.

After some attempts on how to fit everything into the available space (my printer has just 32mm beneath the printing surface with the z-axis being at its lower limit and the printer housing, meaning 13mm for the Andromeda and the adjustment screw), as far away as possible from the heating element and still keeping the adjustment screws accessible, the whole design - with the piezos nicely covered with a housing - looks like this now:

(the thin aluminum plate is L-shaped to give it more stiffness; that is cut away in the view. So it not quite as flimsy as it might look)

While this means I will have to drill some more holes into the z-axis frame, I definitely will see a signal now whenever I tap onto the bed with something. Now It's up to finding the correct settings for sensitivity - as soon as the sensors have arrived and I have assembled all this. Some miniature coaxial cable is also ordered 🙂

When this is running, I want to find a way if I can use the Piezos as "second" z-endstop (i.e. z-endstop controlled by the piezo elements - but in case these fail for some reason, the exisiting less precise endstop detection should kick a bit above that and force the Duet to retry...) but I will open a new thread for that topic unless I find something here in the forum.
