USB Print

This tutorial is only applicable to FLY host computer

Notes

• You need to install it by yourself
• FAST system does not need this step
• This tutorial will replace the klipper/klippy/extras/virtual_sdcard.py file of Klipper.
• It can automatically copy the files in the USB drive to the system's /tmp directory after selecting a print file from the USB drive.
• After the copy is completed, the web command line will prompt File selected
• This file will detect the sdaX folder, and if it does not exist, it will not be executed (where X in sda represents A-Z and 0-9)
• Currently, it has only been tested with the FLY host computer, and other host computers have not been tested.

Usage Method

• Connect to the host computer using SSH software and execute the following command

• Please note that this command will restart the host computer!!!

• This step enables the USB printing function

  sudo rm -rf /etc/udev/rules.d/fly_devices.rules && sudo wget https://cnb.cool/3dmellow/public/static-files/-/git/raw/main/klipper/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 Print Operation Method
