Product Usage Instructions

1. Cooling System

The printer is equipped with a powerful cooling system to
dissipate heat during printing. It includes:

Heat dissipation module and smart fan control for comprehensive
heat dissipation.
Two fans on the sides for model cooling with a maximum turning
rate of 10000r/min.
A powerful auxiliary heat dissipation module with four 4020
ball fans with a maximum turning rate of 11000r/min.

2. Auto Leveling

The printer supports one-click auto leveling along with manual
leveling. Follow the steps below:

Ensure the printer is powered on and the bed is empty.
Select the auto leveling option on the printer’s touch
screen.
Follow the on-screen instructions for the auto leveling
process.
If needed, use the manual leveling option to further adjust the
bed level.

3. Belt Tensioner

The printer features X/Y-Axis belt tensioners for adjusting belt
tightness. Follow the steps below:

Locate the tensioner nut near the belt.
Tighten or loosen the nut to adjust the belt tension.
Ensure the belt is neither too loose nor too tight for improved
printing accuracy.

4. LED Light

The printer is equipped with an LED light beside the nozzle for
better observation of the printed model. It can be turned on and
off freely on the screen when there is insufficient light.

FAQ

Q: What file formats does the printer support?

A: The printer supports Gcode and STLOBJ file formats.

Q: What filaments are compatible with the printer?

A: The printer supports PLA, ABS, TPU, Nylon, and other
filaments.

Q: How can I connect to the printer?

A: You can connect to the printer via WLAN or USB.

Born for FAST Printing
Max 500mm/s 64-bit processor computing power & excellent motion control algorithm Accurate calculation of step time to achieve higher motion accuracy

· Klipper High-Speed Silent Mainboard
Effectively lower printing noise, realize low-decibel running, creating a more comfortable printing space. Equipped with a 64-bit 1.5G quad-core high- performance processor, provide sufficient computing power for printing; 8G storage memory, support 400+ model storage, convenient and fast storage, bringing a better printing experience.

Print Volume225225265mm
Popular size in the market, meets the need of a large majority of users

· All Metal Double-Axis Guide Rails
· The X & Y axes adopt all-metal dual-axis guide rails with U-shaped steel wheels
· Less resistance, more precisive motion · Pretty durable and require less maintenance

· Two Intelligent Independent Heating Areas
· The hotbed is parted into 100 & 150W two heating areas. You can turn on the intelligent mode on the slicer to have it recognize the model size automatically and heat up only one or both two areas when printing different sizes of models, or you can control it on the screen by yourself.
· This is to effectively reduce power consumption, to heat up the bed for different sizes of models in a more efficient way.

· PEI Magnectic Platform+High Temp Hotbed
No need for a spatula. The model will be automatically off the platform after the bed cools down. Better user experience.
The 250W hotbed can quickly heat up to 110°C, meeting the temperature requirements of many kinds of filaments.

· Direct Drive Dual-Gear Extruder
New upgraded self-developed direct drive dual gear extruder, 5.2 times the extrusion ratio, greater extrusion force, the printing accuracy is higher;
Supports PLA, ABS, TPU, Nylon and other filaments;
Much lighter, only 75% of the weight of Neptune 3 Pro.

300°C High Temp Hotend
Copper-titanium all-metal high-temperature throat pipe + unique air duct design, effectively improve the heat dissipation of the throat and reduce the risk of blogging; The hot end of the nozzle is extended, the filaments can be fully melted and extruded more evenly during high-speed printing; Max 300°C, supports printing more kinds of filaments like nylon.

Powerful Cooling System
The heat dissipation module + smart fan control make the heat dissipation more comprehensive during printing;
The powerful auxiliary heat dissipation module is equipped with 4×4020 powerful ball fans to dissipate heat rapidly during fast printing;
The smart fan control will stop all fan work after the print is finished, to save energy, lower noise, and prolong the life span of the fans.

Two fans on the sides for model cooling 2×4015 ball fan Max turning rate 10000r/min
Powerful auxiliary heat dissipation module 4×4020 ball fan Max turning rate 11000r/min

One-click Auto Leveling
Manual + 2.0 Auto leveling
A non-contact high-precision sensor will automatically collect data of 121 points (11×11) on the platform, improving the printing success rate.

· Filament Detection Sensor
· Smart Resume Printing
· Breakage/shortage of filaments will trigger an alarm automatically and the printing will be suspended, avoiding filament waste and printing failure.
· If an accidental power off happened, the printing can continue after power is on, reducing printing failure.

· Magnetic 4.3-inch Capacitive Screen
· Can be operated by hand or fixed on the base, more convenient and free to use
· Support multiple languages: Simplified Chinese, English, Spanish, French, Italian, Russian, German, and Japanese.

· LAN Printing
· Support LAN network · After connection, you can
remotely control and monitor the printing through the WEB terminal.

X/Y-Axis Belt Tensioner
The tightness of the belt can be adjusted by tightening the nut, easy to adjust tension after the belt is loose, improving the printing accuracy; At the same time, the Y-axis profile is widened, making the motion more stable.

X-axis tensioner Y-axis tensioner
Widened

· Z-Axis Double Screw + Double Motor
· Compared with the single-screw motor, the double screw runs more smoothly and has more accurate leveling.
· Better print quality and higher precision.

· Integrated Design
· Unique profile design, gantry structure, the whole machine is more portable and good-looking
· Quick assembly and maintenance, easy to start printing.

· LED Light
Beside the nozzle, there is an LED light, which can be turned on and off freely on the screen. Convenient to observe the printed model.

· LED Light Panel on the top
· Ultra-bright LED light · Can be turned on and off on the screen · Convenient to observe the printing model
when there is no sufficient light.
