I've followed the klipper install guide here with a few minor changes.
The "make" command was returning "make: arm-none-eabi-gcc: Command not found" so I ran "apt install gcc-arm-none-eabi".
This seemed to almost work then I got a "dpkg: warning: files list file for package 'nodejs' missing". I ran the "sudo mv /var/lib/dpkg/info/nodejs.list ." command in the root and reran my make command in the klipper directory. this completed my make command.
I then flashed the micro-controller using the "http://your_raspberryPI_IP:8181" and got a "Transfer complete" and "closed!" return.
Now in Octoprint, the “/tmp/printer” refuses to show up in my Serial Port section even after adding it to "Additional serial ports".
I've restarted the PandaPIv2.9 several times and no dice. I also cant seem to locate the "/tmp/printer" directory on my Pi 3B+.
