▉Product Name:Trianglelab Orbiter V2.0 Extruder LDO Orbiter Extruder V2 LDO MOTOR Double Gear Direct Drive Compatible ender3 CR10 PLA PEI TPU ABS filament Orbiter Extruder V2.0(1.75mm) Warning: Orbiter V2.0 has special gears. This is different from V1.5 gears. We will soon find a way to sell gears compatible with V2.0. Please don't buy the wrong gear. ▉Features: 1.Shorter drive gears 11mm vs 15mm 2.Hardened filament drive gears 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 • Motor current: 1.2A Peak or 0.85A RMS (LDO-36STH20-1004AHG) • Acceleration: 10000 mm/s2 * • Normal motor operating temperature: 60-75°C * The extruder itself without filament can handle acceleration up to 25000mm/s2. Adding weight of the filament it drags along its recommended to have acceleration limit set not above 10000mm/s2
