What is the problem?
I took a break from printing and before then everything was working good. I decided to compile my own Marlin 2.1.2 firmware myself. Octoprint worked for a bit and now will not connect to my printer and says "No Serial Port Found"
What did you already try to solve it?
I used 2 different pi 4s with a fresh install of Octoprint. The new board was working for a little and then stopped. As well I flashed my previous firmware on my board which did not fix the issue. My printer connects to my mac just fine when using Pronterface
Have you tried running in safe mode?
Did running in safe mode solve the problem?
Briefly. It was working but then stopped after a few minutes.
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
