BIQU Orbiter V2.0 Extruder, with Double Gear Direct Drive

Product Information

We are pleased to be carrying the LDO Oribiter 2.0 by Dr. Lorincz Rober, and produced by LDO Motors.

Install the strain_relief or cable_chain_mount with two M3x6/8 screws and the cable_door with a M3x10/12 screw. Close the cable door with a M3x6 BHCS and screw in the extruder tensioning thumb screw.generated by RepRapFirmware Configuration Tool v3.1.4 on Tue Oct 13 2020 12:04:59 GMT-0400 (Eastern Daylight Time)

This makes the gcode independent of the filament diameter, potentially allowing the same gcode to run on different printers.The included Blender file shows the entire assembly complete with screws and should answer most basic questions. P - Sensor type - 1=simple sensor (high signal when filament present), 5= Duet Laser v2.0, 6= Duet Laser v2.0 with microswitch 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 G0 E-70 F300 ; continue extraction slow allow filament to be cooled enough before reaches the gears

RRF3 Pin Names: https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet M106 P7 T35:55 H10 C"Elec.Cab.1" ; Electronics cooling fan that starts to turn on when the MCU temperature (virtual heater 100) reaches 45C The Orbiter V2.0 features Bondtech-quality hardened dual drive gears, shortened to 11mm, that grip filament from both sides. The gears have been reversed, which means the filament path is now closer to the extrusion center. Changes to the motor design contribute to the Orbiter V2.0's approximately 40% higher extrusion force and better acceleration performance compared to the previous V1.5 version. New motor design offers ~40% increase in pushing force in real printing conditions and much improvedFlipped drive gears – filament path closer to the extruder center for a more balanced design and perfect The PEEK gear sleeve has been revised and is now made of a hard and more mechanically resistant material M307 H1 R2.176 K0.417:0.000 D4.28 E1.35 S1.00 B0 V24.1 ; Mosquito magnum, orbiter 2.0 with 40W E3D heater green It's strange as I'm getting the same huge amount of over extrusion as @noghost23 - I would say by a factor of 10 - the rate at which the filament extrudes is so fast - at first I thought I had my gear ratio's wrong but they are 7.5:1 and the rotation distance is 4.637 as recommended. https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Fine_tuning_the_trigger_height
