@Phaedrux Firt of all, thanks for the help!
I did not want to try instable version, just under the beta was not indicated it is an instable version. In most cases, the beta is just a fixed version.
After I realized, there is a stable release, I stick to that.
The documentation is very fragmented, and unprioritized. In point of setup unnecessary things come first, and important one are follows. A guideline is missing, even if I made the setup several times, after a year or so, is hard to to pick up the thread. Duet can act like an idustrial equipment setup guide to prioritising the setup process with one entry point.
The drawings has to be on one place for all the boards: schematics, connection diagrams, topology, and firmwares. The fw files has to have the version numbers in their names!
Just check the macros, they are very important and are hidden somewhere in the tree. And they are also not settled.
these are just thoughts...
Anyway, thanks for the hard work, it is a good hw sw.
