I added lots of tests to the code (and found a bug), refactored some more and added more documentation.
I completely disassembled the rotating table and am trying a smaller stepper motor with the esp32duino. I will need to design and print some parts.
In the mean time I'm starting with a build description / bill of materials. It can be found here: https://github.com/TomKamphuys/NFS/blob/feature/arcs/Documents/BuildDescription.md
Still very rough though.

I'm slowly rebuilding the setup and taking a lot of pictures for a build description in the mean time.
I've been looking for a way to limit the amount of wires, especially to the rotating part. First I tried a powerbank with PowerDelivery that is capable of 20V over USB together with a small 'decoy' to negotiate 20V and power the servo's with it.
For some info, use these search terms: pdc004 pd 20v
I ordered some, but got some fake stuff as far as I can tell.
So I switched and ordered two small PCB's that have a 5V USB connection for the ESP32 boards and take 20V as the input, which I also need for the servo's.
Those who watch closely might notice that the small PCB is upside down, but luckily the voltage is 20.2V, so the only thing giving it away is the '.' .
I'll continue slowly 🙂
Over on audiosciencereview someone is looking into the fitting and reconstruction using python.

could you please put up a link to the audioscience forum? I cannot find the thread you mention. thx!
I played chess as a child and teenager. My interest in it waned when I beat my father for the first time.....
I think that could be one of my weaknesses in other areas too.
Tom I'm following carefully, here and on ASR. I will be building it if the math is solid. And the interface is useable by a reasonably intelligent ludite like me.
We have a few programs that allow us to see the graphs. REW, ARTA, Vituix all allow us to see FRD files. So, if the ability to see the results of our measurements is a difficult thing to ask for, then The ability to see a data file saved and named. If you stick to Octave, it allows an reasonable GUI interface from the little that I know about it.
Even Klippel is not that full featured.
Ideally to see the measurement as we do in REW would be awesome.
