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

Product Information

N.B. If a fan is configured to trigger on a virtual heater whose sensor represents TMC2660 driver over-temperature The Mini Stealth uses a pair of 4010 blowers which produce more airflow than a 5015 blower while being notably less noisy and drawing less current. The depth of these fans do limit Y travel by 3mm on a V0.1 while the door is closed and tophat is on. The width of the main body at its base is also a very tight fit at the extremes of X travel. I have raised my tophat by 20mm which gives the cabling and filament tube plenty of room to breathe. The shroud fits a 3010 hotend fan or a 3007 fan by using a clip-in adapter. 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.

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. 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. So let’s come from the beefy boys to the super lightweight extruders and start with the Orbiter 2.0 manufactured by LDO. The most obvious difference is that it uses an even smaller stepper motor, which has been becoming very popular even on other designs. The housing of the Orbiter is injection molded Glass Reinforced Nylon which makes it very stiff and feels super nice. It uses a planetary gearbox with a 7.5:1 reduction to drive the dual Bondech extrusion gears. The 690 steps per mm allow very precise dosing of material yet will need the motor to spin faster. Due to the popularity of the Orbiter, there is a huge ecosystem around it with tons of mounts for different printers and hotends. The extruder costs 69€ locally and weighs in at 152g yet requires a hotend with a heatsink which brings the system weight to 212g. But let’s see how much this small form factor extruder can push! The Orbiter had a very consistent extrusion force and was able to push 7.2 kilos at normal speeds and 6.8 kilos at 20 mm³/s. Both times the motor skipped showing how well the system is tuned. Just on a side note here - if you’re a tech geek and interested in extruder design, I highly recommend reading the story of the Orbiter 2, which details every design decision they made and is just pure gold!flags, then when the fan turns on it will delay the reporting of an over-temperature warning for the corresponding drivers

Features filament runout detection and push button filament load/unload, designed by Robert Lorincz. Orbiter Extruder V2.0 is a direct drive extruder for 1.75 mm filaments that has been optimised in many ways compared to its predecessor, as well as being lighter, more compact and shorter. The extruder is made of qualitative components such as an injection-moulded housing (GPA12) resistant to high temperatures up to 200 °C and hardened gears from Bondtech, which help it to achieve more mechanical performance and a higher success rate. 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.

The Omniadrop also uses a pancake stepper which connects to a 5:1 planetary gearbox and feeds into a dual-drive extrusion system. The body of the extruder is FDM printed and can therefore be adapted to a range of different mounts. It has a very short filament path and is cooled by a really interesting heat sink design. The Ominadrop 2.1 cost 149€ yet the new V3 only sells for 125€. The complete system weighs 330 g. At medium tension, it achieved 6.9 kg pushing force at 5 mm³/s and 6.2 kg at the faster speed. Both times the filament stripped. As a test, I increased the tension to its limit, which makes the teeth of the gears bite deeper into the filament and made me reach even more than 9 kg of pushing force until the extruder motor skipped, yet this felt very unhealthy for the tensioning lever and the 3D printed housing. 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. Maximum TPU printing speed - the filament can go only into the hotend, no space to be tangled around the gears

The unload button is connected to an input of the control board which is configured to trigger an event which starts the unload macro. This Orbiter 2.0 Mini Stealth is a better fit than the Orbiter 1.5 Mini Stealth in a V2.4 or Trident as the motor no longer interferes with the path of the cable chain. There is a separate 'strain_relief' stl for use in the V0.1. There are also x-frame pieces that allow this Mini Stealth to be installed on a Switchwire. The nozzle is moved up by 3mm compared to the official Switchwire due to the stepper motor being so low on the Orbiter extruder but this also allows a BL-Touch to fit into the x-frame pieces. Flipped drive gears - filament path closer to the extruder center for a more balanced design and perfect fit on delta printers as well M208 X0:250 Y0:250 Z-0.2:230 ; Conservative 300ZL/T settings (or 250ZL) ; These values are conservative to start with, adjust during commissioning.

I thought it was a good time for an upgrade so I installed a new Orbiter 2.0 with filament detector on my Voron 2.4 and the problems began......
