Safely Powering Off your Printer

Save any config changes within the Fluidd interface to avoid losing them.
To safely Power-off your printer, use the Fluidd interface:
Navigate to the top-right menu, select Host, then Shutdown.
Wait until the Green LEDs (visible under the printer) turn off
Then you can power off the machine at the mains power switch.
This ensures that changes stored in RAM are correctly written to the eMMC, preventing data loss.
