Orbiter V2.5 Extruder - LDO Motors - Dual Gear Extrusion for Voron

Orbiter Extruder V2.5

The latest version of the Orbiter improves performance, control, and durability compared to previous models, offering more precise extrusion even under high-speed and high-acceleration printing conditions.

Features

• Shorter drive gears: 11 mm vs. 15 mm on previous versions, improving mechanical response.
• Hardened filament gears: Increased durability when printing abrasive materials.
• Lightweight design: Approximately 135 g, ideal for lightweight motion systems.
• Compact size: About 11.6% shorter, improving integration and usability.
• Increased pushing force: The redesigned motor provides roughly 40% more extrusion force under real-printing conditions.

Mechanical and Design Improvements

• Inverted drive gears: Filament path is more centered, creating a balanced and optimized structure.
• Stainless steel filament guide with a clearance of 0.2–0.3 mm for better TPU handling.
• High-temperature resistant injection-molded housing for better thermal stability.
• Machined PEEK secondary drive gear sleeve for precision and durability.
• Captive grab screw tension mechanism for consistent filament grip.
• Mounting screws aligned with the filament path, improving rigidity and simplifying installation.
• Improved smaller PTFE inlet coupler for a straighter and smoother filament path.
• Motor rotated an additional 10 degrees to improve access and maintenance.
• Integrated filament sensor with automatic load/unload functionality.

Flexible Filament Handling

Designed to significantly improve TPU and flexible material printing through:

• Hardened dual gears
