NOTES

  1. Do not use the printer any way other than described here in order to avoid personal injury or property damage.
  2. Do not place the printer near any heat source or flammable or explosive objects. We suggest placing it in a well-ventilated, low-dust environment.
  3. Do not expose the printer to violent vibration or any unstable environment, as this may cause poor print quality.
  4. Before using experimental or exotic filaments, we suggest using standard filaments such as ABS or PLA to calibrate and test the machine.
  5. Do not use any other power cable except the one supplied. Always use a grounded three-prong power outlet.
  6. Do not touch the nozzle, hotbed or motor while the printer is in operation, otherwise you may get burned.
  7. Do not wear gloves or loose clothing when operating the printer. Such cloths may become tangled in the printers moving parts leading to burns, possible bodily injury, or printer damage.
  8. When cleaning debris from the printer hotend, always use the provided tools. Do not touch the nozzle directly when heated. This can cause personal injury.
  9. Clean the printer frequently. Always turn the power off when cleaning, and wipe with a dry cloth to remove dust, adhered printing plastics or any other material off the frame, guide rails, or wheels. Use glass cleaner or isopropyl alcohol to clean the print surface.
  10. Children under 10 years old should not use the printer without supervision.
  11. This machine is equipped with a security protection mechanism. Do not manually move the nozzle or printing platform mechanism manually while booting up, otherwise the device will automatically power off for safety.

Filament Infill

Preheating Method

  1. Preheating mode 1: Click "Prepare" and select "Manual " to input corresponding values in the column of nozzle temperature and hot bed temperature respectively.
    Preheating mode 1
  2. Preheating mode 2: Click "Prepare" to select "Manual", select "PLA Preheat" or "ABS Preheat" according to the type of consumables, and click "More Preheat" for other types of consumables.
    Preheating mode 2

Note: The printing preheating parameter standard has been adjusted at the factory. PLA preheating standard: nozzle temperature 200°, hot bed temperature 60°; ABS preheating standard: nozzle temperature 250°, hot bed temperature 100°. If adjustment is required due to printing materials or other reasons, you can select "Preheat PLA" or "Preheat ABS" in "Tune - ADV.SET" to adjust the corresponding temperature. Click "More preheat set" for the preheating temperature adjustment of other consumables.

Filament Infill

Filament Infill

  1. When you wait for the temperature to rise, hang the filament over the material rack.
  2. Pass through the Filament Sensor, then press the extruder handle and insert the filament along the extruder hole to the nozzle position. If the filament flows out of the nozzle when the temperature reaches the target value, the filament is properly loaded.

Replacement of filaments:

  1. When the machine has just started printing, cut filaments near the extruder and slowly feed filaments until they are fed into the material barrel.
  2. When printing has finished and the machine has cooled down, heat the nozzle to 185℃+, then draw the filaments out and replace them by referring to step 1.
  3. To change the filaments during printing, adjust the printing speed to 10% and refer to step 2 for replacement.

Routine Maintenance

Lubrication and maintenance

Tip: Please lubricate the guideways, sliders and screw rods in the blue area regularly (as shown in the figure). It is recommended to do it once every 500 hours of printing.

Lubrication and maintenance

Use and maintenance of the magnetic adhesive sticker

Tips: This hotbed can be heated up to 100°C. It is strictly forbidden to remove the printing platform when the temperature of the hotbed is higher than 70°C. Since the printing platform is a wearing part, it is recommended to clean it regularly to ensure that the first layer of the model is adhered. Please replace it in time if it is damaged.

  1. Remove the printed model from the machine together with the platform and partially bend the platform slightly to separate the model from the platform.
  2. Filaments can be scraped off with a blade included in the tool box. Be cautious of safety when using the blade.
  3. When printing large models, it is recommended to apply solid glue evenly on the surface of the platform; if the platform is over-glued, it can be cleaned with tap water and wipe the surface dry afterwards.

Extruder kit maintenance

Tips:
Extruders are vulnerable parts. It is recommended to do the periodic inspection of extruder if it is used for more than three months to check whether the fan has foreign objects on it or whether it is damaged, which will affect the heat dissipation and cooling. If the extrusion is uneven, intermittent and the printed model has no extrusion or has false layer, it is recommended to do the heat break cleaning or replace the nozzle kit with a new one as a priority. Refer to the nozzle kit.
