Not losing specifying Port for specific printer when power cycling the printer

3degos

I am currently running a few ender 3 with a raspberry pi 3 but when I power cycle my printers the serial ports between the printers get mixed up. Is there a way for the raspberry pi to remember which USB port goes with which serial port?

Sure. The real ports in /dev are ordered by detection so may change. If you use /dev/serial/by-path they are determined by the usb port plugged in.
