BIQU Panda Revo MK8 Dual Gear Extruder, Double Gear MK8 Extruder 3D Printer Dual Driver Stock Feeder All Metal 1.75mm Filament Extruder Kit for CR-10S Pro/CR-10/ Ender 3 V2/Ender 3/Ender 3 Pro

If you own a Bambu Lab X1C, you know the "Bambu struggle": dealing with those tiny, proprietary heater/thermistor clips and the chore of swapping out entire assemblies just to change a nozzle size. After cycling through several stock replacements and fiddling with finicky off-brand alternatives, I finally bit the bullet on the BIQU Panda Revo. Here is why it’s worth every penny. Installation: As Easy as it Gets One of my biggest concerns was a complicated teardown, but the installation was a total breeze. BIQU provides detailed, step-by-step instructions that are actually easy to follow. It’s a direct fit for the X1C carriage, and because it utilizes the Revo ecosystem, you aren’t dealing with those microscopic wires that seem designed to break the moment you look at them. The "Revo" Advantage The real magic here is the Toolless Nozzle Swap. No more: Unplugging delicate JST connectors. Thermal paste messes. Wrangling the ceramic heater spring. You simply unscrew the nozzle with your fingers (once cold!) and pop a new one in. Whether you’re switching from a 0.4mm for a detail print to a 0.6mm for abrasive filaments, it takes seconds, not minutes. Is the Price Justified? I’ll be honest: I delayed this purchase for months because of the "sticker shock." However, looking back at my order history, I realized I had spent nearly the same amount on multiple replacement stock hotends and various "all-metal" clones that never quite performed right. Learn from my mistake: Don't let the upfront cost scare you. When you factor in the time saved and the durability of the Revo heater core, it pays for itself. Pros True Plug-and-Play: Designed specifically for the X1C ecosystem. Cold Swaps: Change nozzles by hand without tools. Reliability: Excellent thermal consistency and significantly fewer clogs than stock. Build Quality: It feels like a premium, professional-grade component. Cons Initial Cost: Higher entry price than standard replacements. Ecosystem Lock-in: You must use E3D Revo nozzles (though their quality is top-tier). Final Verdict The BIQU Panda Revo is a noteworthy upgrade that transforms the X1C from a great printer into a seamless production powerhouse. If you find yourself frequently switching between materials or just hate the maintenance of the stock assembly, stop buying replacements and just get this. It should have been my first purchase.

With the latest Ender 3 v2 the motor has changed. The shaft is no longer keyed and the factory feed roller is pressed onto the shaft. As a result the new set screw is too high to catch the shaft. Also you need to get the old pressed roller off before you can even see this issue. The result is that this will NOT work on the newer Ender 3. If you look down at your extruder and the motor shaft does not stick up above the roller gear then this will not work. I always wondered how you connect the finger wheel filament feeders you find on Thingiverse for the Ender 3. Now I know with their latest model none of those will work either. Hmm...I guess I can kind of blame Creality for this but the vendor of this extruder needs to be current as well. If they made the lower part of the gear longer and put the set screw down there then it would work but you still have to get the pressed roller off the motor. Now that sounds all negative and if you have that model I guess it is - however, their customer service is absolutely great. They reached out to me immediately to clarify and resolve the issue. Although in the end it has been turned over to their engineers for a permanent solution, they gave me options and refunded super quick. I will definitely buy from them again.

This nozzle just clogs constantly and so badly I have to disassemble the whole extruder to get it working again. I tried upgrading the nozzle to a $60 obxidian nozzle...same thing. This product is a waste of $140 and I can't return it because the box is gone. I exchanged it for a new one and guess what...same issue. On top of the $140 I wasted, I wasted an additional $60 on the new nozzle, $40 on another replacement nozzle trying to see if the nozzle was the problem, $100 on a new all metal extruder gear box and assembly, and no matter how much new upgraded tech I throw at this POS, it simply refuses to work. I run a business and this thing has wasted countless hours with failed prints where the nozzle just prints in mid air once the nozzle becomes hard clogged, rolls of filament, and hours of disassembling and reassembling the extruder to remove the clogs. In short, this company needs to go out of business. The product is awful and I am stuck with metal paperweight because I have no way to return it.

Has been working great for a few prints now using PLA on a Bambu X1C set at 30mm3/s max. So far only a couple hundred grams through it. Make sure to look up install and use instructions. It will 'work' plug n play, but you wont be getting any highflow out of it without setup. There is some weird wire routing behind the fan to do. Also, make sure to run printer calibration after install. I look forward to the quick change nozzle because swapping the stock system was a pain. I havent tested changing the nozzle since the install, but have some new nozzles coming in soon.

Ordered this for my Ender 3 pro as the teeth were worn and no longer feeding the filament consistently. I have installed similar hardware on other printers, so this one wasn't a big deal, but for someone new to this, the lack of decent instructions may be a bit frustrating. The only other con for me is the inability to add an extruder knob due to the design. Not a deal breaker, but maybe future versions could allow for this. Now for the good: This thing is well built and works like a dream! Anyone that has dealt with the old style single gear extruders know how aggravating feeding new filament can be! Sometimes it seems almost impossible to get it aligned and feeding properly. No such issue with this one. Feeds right through, and no slipping or jumping. I'm also not seeing the filament dust accumulate around the drive gears like in others. Would definitely purchase again!

This thing is amazing I had the micro Swiss flow tech and it was good but after making the upgrade my prints are flawless easy install great fit durability seems way better also

First let me say this hot end is one of the best on the market for its price range. It’s every actual meaningful upgrade you can do to a hot end packaged into a ready to install product, no searching around for parts trying to peace things together with random Chinese products and waiting months for things to come from Ali express. But sadly I cannot recommend this product to MOST of the ender 3 market. Pros. Best hot end under 100 bucks imo, no mods to the hot end are needed. Think of it as a “fully upgraded” e3d bi metal heat break, copper block, cart thermistor etc. Btw the built in Bowden tube connector is a feature not a con like some reviews said, it shortens the distance from the extruder to the hot end on direct drive. Beautiful construction, like stunning finish for a product in this price range it looks like it came from a custom CNC shop. Cons It is NOT bolt on compatible with most* ender 3 (and ender 3 compatibles) printers. This hot end is SIGNIFICANTLY shorter than the stock ones used in all the ender 3 off the shelf printers, as well as most aftermarket ones (it’s to date the shortest one I have ever used on an ender) the problem is this causes it to create severe clearance issues with bl touch, fan shrouds, fans, part cooler fans etc being too long for the print head to reach the bed. This can easily be worked around for people who are “makers” modifying the entire assembly around it (shortening abl sensor mounts, lifting fans, custom fan mounts, custom fan shrouds etc) max so to speak of course BUT this product is sold as a direct replacement, it is Not. Adding to this the heat block itself is quite long front to back, meaning I’m almost all applications it interferes with the x carriage back plate and the sock is almost impossible to install without removing the hot end. Meaning a nozzle change requires you to 1 remove the whole fan shroud, 2 remove the hot end, 3 remove the sock and the nozzle, 5 reinstall the new nozzle and the sock, 6 reinstall the hot end, 7 reinstall the fan shroud. 7 step nozzle change on any ender printer if you use the sock. How convenient. Add onto this that the heat sink is not bolted to the heater block making it a huge risk of snapping the (proprietary) heat break. The fix for this is a set of longer screws and some washers to add clearance to the hot end from the carriage. Likely less than a cent worth of parts for the manufacture to include in the product DESIGNED to be compatible with the ender series printers. Now you have a new problem Your hot end fan will now have clearance issues. Again can be worked around but is just simply annoying for a upper end product in this industry being sold as compatible. Overall the problems with this product is that it does work and works amazingly, but it’s being sold as a compatible product for the ender 3 yet requires a complete overhaul of the x carriage accessories to make it work. This is fine if the product is sold this way but this is sold as a compatible product, a huge portion of the ender market is entry level users without any skill or knowledge about the printers, this advertising is just targeting them to sell them a product the do not need, and in many cases will not be able to use without spending significantly more money and time than is needed.

I originally bought the Creality Spider for my E3V2 and quickly realized it was not a direct replacement. Returned the spider and order this instead. Be warned, this does not include the appropriate thermistor. You will need the cartridge style thermistors for this to work properly. The adapter it includes does not work very well. After running the Auto PID tuning and confirming esteps were still good, it’s been printing perfectly for several weeks. It’s annoying that you have to almost remove the hotend to get the silicone sock off to change nozzles. I’m not interested in adding spacers for clearance when my printer is running well. All in all, it’s a perfect upgrade!
