USB Drive Printing

This tutorial is only applicable to the FLY host machine.

Notice
  • You need to install it yourself.
  • This tutorial will replace the klipper/klippy/extras/virtual_sdcard.py file in Klipper.
  • It allows automatic copying of files selected from a USB drive to the system’s /tmp directory.
  • After the copy is completed, it will prompt File selected in the web command line.
  • This file will detect the sdaX folder; if not found, it will not execute (where X in sda represents A-Z and 0-9).
  • Currently, only the FLY host machine has been tested; other host machines have not been tested.

Usage Instructions​

  • Use an SSH software to connect to the host machine and execute the following command.
  • Please note that this command will restart the host machine!
  • This step is to enable USB drive printing functionality. 
    sudo rm -rf /etc/udev/rules.d/fly_devices.rules && sudo wget https://upyun.pan.zxkxz.cn/Utils/fly_devices.rules -O /etc/udev/rules.d/fly_devices.rules > /dev/null 2>&1 && sudo chmod +x /etc/udev/rules.d/fly_devices.rules && sudo service udev restart && sudo reboot
