USB Drive Printing

This tutorial is only applicable to the FLY host machine.

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

Usage Method​

  • Use SSH software to connect to the host machine and then execute the following command.
  • Please note that this command will cause the host machine to restart!
  • This step is to enable USB drive printing functionality. 
    sudo rm -rf /etc/udev/rules.d/fly_devices.rules && sudo wget https://cdn.mellow.klipper.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

USB Drive Printing Operation Method​

Backup and Download File​

  • Please note that this command will stop Klipper.
  • This step is to enable the automatic copying of USB drive files to the system's /tmp directory when selecting a USB drive file. 
    sudo systemctl stop klipper && mv ~/klipper/klippy/extras/virtual_sdcard.py ~/virtual_sdcard.py && curl -kfsSL https://cdn.mellow.klipper.cn/firmware/virtual_sdcard.py -o ~/klipper/klippy/extras/virtual_sdcard.py && sudo systemctl restart klipper

This step is to restore the original file​

  • Please note that this command is to restore the original Klipper. 
    sudo systemctl stop klipper && mv ~/virtual_sdcard.py ~/klipper/klippy/extras/virtual_sdcard.py && sudo systemctl restart klipper
