    110V or 220V, you can switch the input voltage.
  • Whether Alfawise U20 3D printer has filament run out detection funtion?

    It has filament run out detection funtion.
  • Can i change the nozzle to 0.2 mm or 0.3 mm?

    Yes, you can.
  • Does Alfawise U20 support auto leveling?

    No, it doesn't, you need to adjust it by manual.You can refer to this post: How to debug 3D printer’s heating platform
  • Will it come with filament?

    It comes with 200g PLA filament.
  • Why the filament can't stick on the heat bed?

    1. Paste high temperature adhesive tape on the heat bed or using 3D print heat bed glue.

    2. The distance between the nozzle to heat bed is very important, please keep the distance is about 0.2 - 0.3mm.

    3. Some types of filament need higher temperature of heat bed, usually PLA is 50 - 60 degree, HIPS/ABS/PC is about 80 - 105 degree.

  • Extruder cannot heat up to setting temperature, what can i do?

    1. Check the blowing fan is on off or not when extruding, if on please turn off it first.

    2. Check whether the heater wire connected well or not.

    3. Disconnect the heater from the control board. test two ends of heater by a multimeter(using resistance grade), if resistance is over 10 OHM, it means the heater is broken.

  • How do I know the links to update the firmware? If SD card data is lost, how can we find it?

  • What should I do if I cannot resume printing after power shutdown?

    If you suddenly lose power when you start printing parts, the machine will not save the print data. Unless we print more than 0.5mm in height, we will support the power outage recovery. If the height is less than 0.5mm, we suggest printing again.
  • Is the firmware used by U20 an open source Marlin firmware?

    No, it is not.
