LDO Orbiter extruder V2.0

Version 2.0 of the Orbiter extruder designed by Dr. Robert Lőrincz and manufactured by LDO. Updates from the previous version include:

• Shorter hardened drive gears 11mm vs 15mm manufactured by Bondtech
  
• Weight reduced to ~135 grams
• Smaller more compact dimensions (11.6% shorter)
• New motor design offers ~40% increase in extrusion force in real printing conditions and much improved acceleration performance
• Flipped drive gears – filament path closer to the extruder center for a more balanced design and perfect fit on delta printers as well
• Stainless steel filament exit guide with 0.2-0.3mm clearance to drive gears for best TPU printing experience and extreme wear resistance when using abrasive filaments.
• High temperature resistant housings, GPA12
• Machined PEEK secondary drive gear sleeve
• Tension mechanism with grab screw design
• Mounting screws in line with filament exit path – improving housing stiffness and easier mounting
• Perfectly aligned filament path
• New smaller and more stylish PTFE tube input coupler
• Motor position rotated by additional 10 degrees for easier maintenance and assembly
• Extremely low backlash ~0.06mm
• Filament sensor add on with auto load and unload button add on feature
• And many more small changes to improve mechanical accuracy and design look
