BIQU Orbiter V1.5/V2.0 Extruder Dual Driver Gear Extrusion 3D Printer Parts For CR10/10S,Ender3/3 pro,Ender5

Great extruder that works very well. Has plenty of torque and great grip strength. Also EXTREMELY small and lightweight. I knew it was small when I bought it, but I didn’t realize how small. To put it in perspective, the entire assembly with the extruder and stepper is about the size of a BMG extruder without a stepper and weighs about the same as a pancake stepper without an extruder. There’s really only 2 concerns you might have with this. #1, the motor can’t run in stealthchop mode, so if running high speeds and extrusion rates, sometimes it makes a slight buzz, but if you’re standing more than 3-4 feet away, you can’t hear it, and unless you have a crazy quiet printer (like I do) you aren’t even gonna notice it. Only other concern is you definitely don’t want to be conservative with the spring tightness, as too little tension will not grip the filament properly and will shred it. Now as for the gears, I would HIGHLY recommend the 2.0 over the 1.5. The 1.5 if I’m not mistaken uses bmg gears compared to the custom made gears in the 2.0 which are nearly double the size. My last thing to note is that it has a VERY tightly constrained metal filament path. This means if you don’t melt the end of the filament perfectly, I have had some trouble getting filament out. Pretty much, I would just use a gcode command to slightly push the filament in and rapidly pull it out while the hotend is hot, or just manually do it. Otherwise, great extruder though.

werry nice

After replacing the extruder, the printing improved significantly. Complete satisfaction.

Consistent and accurate extrusion. My print quality got better instantly.

After purchasing the Orbiter v1.5 and looking at it poor construction and then finding out it was not one of Dr. Lorincz's designs I looked for the V2.0 which I found on your site.
This Extruder is designed correctly and regarding the filament path it is perfect. This extruder should be on every printer gantry for unmatched filament feed. I could not be more pleased.
