A nice demonstration, but for my peace of mind that it is truly consistent, can you try the following.
- Get a map of the surface using at least a 5 by 5 grid and save the readings.
- Move the sensor to two other positions fairly far from, and not symmetrically the same as the first position
- Repeat the mapping of the surface for each new position.
- Compare the grids, subtracting each from the original. Obviously there will be a travel time difference but dynamic (Chladni Plate type) errors should be obvious, often being in the opposite direction to what you would expect.
If it passes this test it should be good to go - there still could be problems in other circumstances (see Boeing 737 Max Angle of Attack sensor) but due diligence will have been done.

Very interested, where can I find the files?

PM with address sent.
I agree about automation having unpleasant surprises for the unwary. My own favorite aircraft was a Piper J3 "VP-YEM" without so much as a starter - the only electrics were the mag switches

I have ordered an AXE027 cable and will download the software and drivers. I will run some tests and report back with results.

I have just received the sensors and hope to work on them early next week.
The plan is to set up some dummy beds - 220 mm square in 2mm and 4mm aluminium on my Cartesian Printer. I will initially try them in the manner that you designed them for and then look for areas where the signal might be compromised. To do this I will take the signal straight from the piezo to one of my own conditioners so that I can extract the data in the time immediately before your conditioner trips. On another channel, I will monitor the contact point using a gold flashed nozzle and contact plate to get the time for the contact event signal to reach the piezo through the bed.
Hopefully, I will be able to find that your method is robust and repeatable, or if not, that some simple "do this" or "don't do that" instructions can be found to guide potential builders.

I am very interested in this sensor. Do you have the STL and Gerber files available for the under bed version?

Certainly:

I've been using it for over a year now, and it's still reliable and consistent. Have fun, and let us know what you think.

Thanks for the quick reply, but I only find the 35mm_Nema17_Inserts.stl at the link you provided. Is the 41mm_Knock_Gerber.zip file for the underbed version?

rq3,
Thanks for making your design available. I have built one and installed it on my Anet A8 printer. I am very satisfied with the performance so far. I don’t think I am getting the performance that you get, but I think it is because of the lack of rigidity of the A8. It is much better than the other probes I have tried.
