Get USB Serial from Motherboard - Guilouz/Klipper-Flsun-Speeder-Pad GitHub Wiki

  • 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.
