Ortur 4 V2 FDM Industrial Grade Dual-axis GRS Linear High Speed Open Source 3D Printer

Main Features:
- Ortur 4 is a stable, heavy-duty 3D printer
It adopts the design of many industrial-grade 3D printers. For example, the chassis (1.0mm sheet metal, other structural parts 3.0mm sheet metal) is especially emphasized. It ensures the stability of the center of gravity when printing at high speed.

- Higher printing speed and precision
Use the GRS built-in dual-axis linear guide for CNC machines as the XYZ axis, which can support faster printing speed (It can set the i3 machine than the ordinary aluminum profile.) 2 times faster than the normal printing speed, and higher printing accuracy. Moreover, the service life of linear guides is much longer than that of ordinary aluminum profiles. Although it is expensive, it is more precise and durable.

- Independent design for easy maintenance
The print head adopts the separate design of the terminal block + bracket + outer casing, which is easy to maintain and repair. Moreover, the print head has been designed to reduce the weight and weighs only about 400 grams. The thermistor and the heating rod are locked in the heating block to prevent the fire from falling off.

- Long running time, safe and reliable
Specially optimized the motherboard MOS tube redundancy design to prevent fire hazards, for example, the hotbed MOS tube supports up to 80A current (normal motherboards are generally designed only 15-20A current ). Moreover, the large fan is actively cooled to ensure that the motherboard runs stably for a long time.

- Industrial-grade flexible cable and full-chain storage line
Industrial-grade flexible cable for high-power hotbed (repeated bending up to 10 million times) to prevent short-circuit fire hazards caused by current overload and line aging.
Full-chain storage line, beautiful, to prevent the safety hazard caused by messy lines.

- Powerful latest Marlin2.0 operating system
Ortur 4 uses the latest Marlin2.0 operating system and is more powerful. And comply with the firmware open source agreement, so that the majority of enthusiasts to deep debug the machine.

- Auto level + Z offset = True auto leveling
Through the sensor to detect the surface warpage of the hotbed, Ortur 4 automatically raises or lowers the Z-axis, and then the distance from the nozzle to each point of the hotbed is always controlled at about 0.1MM, realizing the automatic leveling of the hotbed.

- Safety protection
There is "temperature abnormal protection / Thermal Runaway Protection" function.
There is "breaking detection" function.
There is a "power off and continue to play" function.

Notes:
- Platform board: aluminum hotbed + glossy sticker (aluminum + light film)
- Frame material: sheet metal + GRS built-in dual-axis linear guide
- Platform temperature: MAX 100 Deg.C
