Get USB Serial from Motherboard

• Connect your printer to one of the Speeder Pad's USB ports.

• Connect in SSH then enter the following command to retrieve the motherboard USB serial:

  cd ~ && ls /dev/serial/by-id/*
  

• You should see the USB serial appear like this (serial is different depending on the motherboard):

  

• In case you use same multiple printers connected on the Speeder Pad and you only see one serial when running this command, enter this one instead:

  ls /dev/serial/by-path/*
  

• If the second command shows multiple results, adjust the path of the serial accordingly, so all instances of /by-id/ should be replaced with /by-path/.

• Go to your Mainsail Web interface then click on Machine tab.

• Open printer.cfg file and find [mcu] section.

• Edit the following existing line with serial you have just obtained like this:

  serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
  

• Click on SAVE & RESTART at the top right to save the file.

• Your printer should connect to your Speeder Pad.
