SPECIFICATIONS
Model Number: Orbiter Extruder V2.0
Item Type: Extruder
Brand Name: BIQU

  Features:
  1.Shorter drive gears 11mm vs 15mm
  2.Hardened filament drive gears manufactured by Bondtech
  3.Weight reduced to ~135 grams
  4.Smaller more compact dimensions (11.6% shorter)
  5.New motor design offers ~40% increase in pushing force in real printing conditions and much improved          acceleration performance
  6.Flipped drive gears – filament path closer to the extruder center for a more balanced design and perfect fit on      delta printers as well
  7.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.
  8.High temperature resistant injected housings, GPA12
  9.Machined PEEK secondary drive gear sleeve
  10.Tension mechanism with grab screw design (Captive Grab Screw)
  11.Mounting screws in line with filament exit path – improving housing stiffness and easier mounting
  12.Perfectly aligned filament path
  13.New smaller and better PTFE input coupler
  14.Motor position rotated by additional 10 degrees for easier maintenance and assembly
  15.Filament sensor add on with auto load and unload button add on feature
  16.And many more small changes to improve mechanical accuracy and design look

  Basic Configuration:
Steps: 690 steps/mm @ 16 micro-stepping
Max. instantaneous speed change (jerk): 600mm/min(RRF), 10mm/s (Marlin) (recommended 300/5)
Pressure advance: 0.02~0.03s - to be calibrated
Retraction: 1~1.5mm - to be calibrated
Retraction speed: 120mm/s, reduce it to 30mm/s when printing TPU
Motor current: 1.2A Peak or 0.85A RMS (LDO-36STH20-1004AHG)
Max. acceleration: 10000 mm/s2 *
Normal motor operating temperature: 65-75°C
Drive motor with stealth chop disabled!

Extrusion performance:
Optimized the motor
design to maximize its
torque in the speed range
the extruder needs it.
The result is ~40% increase
of the pushing force in real
printing conditions.
Retraction speed up to
120mm/s
Acceleration up to
3000mm/s2
The main re-design targets for the Orbiter v2.0 where:
More compact and less weight
Better fit to printers – lightweight extruder for printers without limiting print space
Metal filament exit guide – for perfect flexible and abrasive filament printing experience
Increase extrusion force and maximum acceleration.
