Nozzle diameter: 0.6 mm
Maximum set temperature of nozzle: 260℃
Printing speed: 50-120mm/s
Maximum set temperature of the platform: 60℃
Leveling mode: Automatic leveling
Supporting material: PLA/PEGT
Print size: 60060080mm 80080080mm
Layer accuracy: 0.1-0.4 mm
Printing accuracy: ± 0.1mm -
Placement conditions
The equipment should be placed in a clean, dust-free and dry environment, and away from fire sources, dangerous sources and high-power electrical equipment.
The equipment must be equipped with random supporting feet to enable the equipment to run stably.
The environmental temperature should not exceed 35℃, otherwise it will easily lead to blockage, and it is easy to warp the shell when it is used in low temperature (below 10℃). -
Printing Temperature and Speed
The maximum printing temperature of the equipment is 260℃, so the printing temperature should be adjusted according to the speed. If the temperature is too high, bubbles will be generated on the surface, and the printing quality will decline. If the temperature is too low, regular dot nodes will appear on the surface, which should be adjusted according to the actual printing situation.
The following are common speed and temperature matching:
Printing speed: 60mm/s Printing temperature: 210℃
Printing speed: 80mm/s Printing temperature: 230℃
Printing speed: 100mm/s Printing temperature: 250℃ -
Hot Bed Temperature
The maximum temperature of hot bed should not exceed 60℃, otherwise the material will soften. The recommended temperature for PLA materials is 40-50℃, and the recommended temperature for PETG materials is 50-60℃ -
Shutdown Precautions
When turning off the printer, the nozzle temperature should be reduced to below 100℃ to prevent the nozzle from blocking. -
Loading and Unloading Precautions
When printing materials are loaded, all materials on both sides should be loaded one by one, and the extrusion of materials should be controlled. Printing can only be carried out if both materials are extruded, otherwise there will be a risk of blockage.
When replacing or discharging consumables, the nozzle temperature should be heated to above 180℃, and the two materials should be extruded first, and then the material return operation should be carried out after no blockage is confirmed. -
Precautions for 3D Touch Automatic Leveling
Under normal conditions, the red and blue indicators of 3D Touch are always light up. When there is a fault, the red lights up. At this time, it should be checked whether the probe is bent, resulting in error in return. When the 3D Touch is leveled or working back to zero, the blue lights up.
Be careful not to hit the 3D Touch probe with external force. -
Precautions
The highest temperature of the nozzle can reach 260℃. It is forbidden to touch the heated nozzle directly by hand to prevent scalding.
The maximum temperature of the hot bed can reach 60℃ and above. Avoid touching the hot bed directly by hand for a long time to prevent scalding. In addition, it is forbidden to place flammable materials, such as high-pressure gas and flammable substances, on and around the hot bed to prevent accidents.
It is forbidden to touch the motor by hand when working, and the surface temperature can reach up to 70℃ to prevent scalding; In addition, it is forbidden to touch gears, transmission belts, etc. to prevent mechanical injury, and it is also forbidden to use other articles to touch gears, transmission belts, etc. to prevent danger. -
