Features:

   1.Shorter drive gears 11mm vs 15mm

   2.Hardened filament drive gears manufactured by Bonditech

   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             de1ta 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.
