Screen Wiring

Power Off Before Operation

Before starting, completely turn off the printer and disconnect the power supply. Do not plug or unplug cable harnesses, organize interface wiring, or touch terminals while the printer is powered on.

When connecting a TFT or HDMI screen, carefully confirm the direction of the FPC cable to avoid reverse insertion which may cause equipment failure.

• TFT resistive touchscreen configuration method
• HDMI screen configuration method

• You need to change the part after screen= to fly-tft-v1
• If you want to use FLY Screen, you need to set klipper_screen=0; if both klipper_screen=1 and fly_screen=1 are enabled, KlipperScreen is enabled by default
• You need to change fly_screen=0 to fly_screen=1
• Below is a reference after modification
