What is the problem?
I have an Ender 3 Pro and a Raspberry PI 3B+ running octoprint with logitech camera connected to one of the serial ports. Pi is connected to the printer over serial.
The problem is that PI is giving power to the printer and the outcome is that the board and the LCD screen is powered and parts of the printer UI are working. This is happening no matter if the printer is turned on or off.
What did you already try to solve it?
I have tried to disable the power going off the USB ports of the PI but unfortunately if I want to do it I need to turn the power of all the ports off (which means that I am loosing the connectivity to the camera). I would like also to avoid masking with electrical tape the pin.
Is there something I can potentially do?
