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. G31 X-3.5 Y36 Z2.927 S0.02 ; Customize your offsets appropriately - do a paper test, and put the probed value in the Z value here Pre-assemble the extruder pieces before installing into the shroud. Use two M3x8 BHCS to install the Orbiter 2.0 extruder. It helps to have both screws in the Orbiter before putting it in place. Start the screw by the latch and then the blind screw should be easier to align.

G0 E-70 F300 ; continue extraction slow allow filament to be cooled enough before reaches the gears New motor design offers ~40% increase in pushing force in real printing conditions and much improved Volumetric extrusion is an option you can set in some slicers whereby all extrusion amounts are specified in mm3 (cubic millimetres) of filament instead of mm of filament. I have added new stretched versions that should fit the Rapido UHF, Dragon UHF and the VolcoMosq hotends. The Dragon UHF and Rapido UHF hotends can fit in the same shroud. The UHF hotends will reduce Z travel by 8.5mm and the VolcoMosq by 3mm. I cannot verify the fitment so if there are any issues please leave a comment.New motor design offers 40% increase in pushing force in real printing conditions and much improvedin acceleration performance M906 X1150 Y1150 Z900 E560 I60 ; Motor currents (mA) - WARNING: Conservative - May trigger stallguard (and prematurely during homing) if sensorless. 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 One of the most expected project of 2021, the Orbiter v2.0. A high precision direct drive extruder custom manufactured by LDO Motors. This is LDO’s finest direct drive extruder system in which they have integrated all what they learned about extruders in the past years.

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. Use two M3x40 BHCS to secure the toolhead to the x-carriage in a V0.1/V0.2. For installation in a Trident or V2.4 use two M3x50 BHCS.
