Common questions about manuals, registration, and support for this brand.
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.
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.
Firmware, Slicer software, and detailed tutorials can be found on the official FLSUN website support page or the FLSUN Wiki at wiki.flsun3d.com.
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.
