While attempting to debug a problematic ESP32 recently, I needed to connect to it via the COM port from my PC in order to get more logging from the unit. In attempting to do this, I ran into a very peculiar interaction. I couldn’t connect to the ESP COM port while CURA was open. I guess it was attempting to connect to a 3d printer on the port? Whatever the cause, it was a rather annoying encounter. Once I closed it out, I was able to connect and get the logging I needed.
Just another tech blag
