Updating MCU Definitions

Your machine should be powered up, with the controllers disconnected from the Raspberry Pi.

Connect the X/Y/E to the Raspberry Pi

Open an SSH terminal, and issue the following command ls /dev/serial/by-id/

Copy this line to notepad on your PC. Make sure to note somewhere that this is the X/Y/E MCU.

Plug in the Z controller to the Raspbery Pi.

Issue a command in your SSH terminal, ls /dev/serial/by-id/

Note the new ID that shows up. You will also see your X/Y/E controller show up.

Copy this new ID to your notepad, and note that it is the Z controller.

Open your printer.cfg file in whatever editor you feel comfortable with. My preference is to use nano via a SSH terminal, but if you prefer to use WinSCP you're welcome to do so.

In the section [mcu] on the line starting "serial:", copy the path you copied to your notepad for the X/Y/E controller.

Be sure you have the whole path as outputted by the terminal. It requires /dev/serial/by-id/ at the start.

In the section [mcu z] on the line starting "serial:", copy the path you copied to your notepad for the X/Y/E controller.

Be sure you have the whole path as outputted by the terminal. It requires /dev/serial/by-id/ at the start.
