• What should I do if my FLSUN printer detects a filament clog?

  If the filament clog detection feature is triggered, follow the troubleshooting steps in your user manual. This typically involves clearing the nozzle using recommended heating techniques or tools provided in the accessory box.

• How do I switch the input voltage on my FLSUN printer?

  Before powering on the printer, ensure the voltage switch on the power supply matches your local voltage (e.g., switch to 115V for US or 230V for EU). Failure to do so may damage the device.

• Where can I find firmware updates and user guides?

  Firmware, Slicer software, and detailed tutorials can be found on the official FLSUN website support page or the FLSUN Wiki at wiki.flsun3d.com.

• How do I calibrate the bed leveling on FLSUN printers?

  Most FLSUN models feature auto-leveling. Navigate to the 'Calibration' menu on the touchscreen, select 'Bed Leveling' (and 'Motor Calibration' or 'Vibration Compensation' if available), and follow the on-screen prompts to complete the process.
