I highly recommend starting it up before you start the mainline process. You will need to know your serial numbers from the MCU of the Main Board and the MCU from the toolhead board. you can get them one of 2 ways.
Open your printer.cfg file and look for the lines as is pic.
SSH into your printer with putty and enter this command to pull out your serial numbers.
ls -la /dev/serial/by-id/
