Is there a simple way to write a magic file to set these parameters just by inserting a flashdrive? It would help streamline each new machine setup. If I could put a default installation (where the IO is already named, TCP taught, etc) along with our CAP on the same flashdrive as this magic f… Take a look at my post here. I used magic files to modify some of the system files. ---

That’s…what the post details how to do. Polyscope is reading the contents of those files. If you change them in the linux backend, you change what Polyscope reads/boots with. If you can find the file you’re interested in changing via the terminal, then you can use the process outlined in that post to do so. Just replace one of the file paths I had used with the one you want. In fact, I was already modifying the .urcontrol file in that example > I made these mostly by either copying it from my simulator, or else copying it from the actual robot controller. Then I changed what I needed and wrote the cp command to write it back. So copy the .urcontrol.conf, edit it with whatever text editor you want, save it to your flashdrive, and add/modify a line of the magic file to cp/path/on/URcontroller your/saved/path ---
