I would like to know which should be powered on first (raspberry pi or 3d printer) and how long should I wait to power the second device?
The reason for this question is because I noticed that the rpi would not always connect to the 3d printer (via USB) so I think the order that the devices are powered on has something to do with it and also the wait time before connecting to the 3d printer.
I would randomly get this error
Error: Failed to autodetect serial port, please set it manually.
Currently it is set as
Serial Port = AUTO
Baudrate = 115200
