BIQU Nebula Extruder, Dual Gear Extruder Compatible with Voron 2.4 StealthBurner/EVA3 Print Head, Lightweight and POM High-Temperature Resistant, 6KG

The BIQU Nebula Extruder is positioned as a lightweight and efficient solution for users looking to enhance their 3D printing experience, particularly with compatibility for setups like the Voron 2.4 StealthBurner. Customers have generally appreciated its compact design and ease of installation, allowing for a smoother integration into various projects. Users have noted the straightforward installation process facilitated by included mounting files. Most importantly, for those printing with TPU, the extruder has proven reliable, achieving Consistent results without jams—a significant advantage for filament types often prone to issues. However, the extruder is not without its limitations. Some users have reported challenges when it comes to high-speed printing, stating that the Nebula struggles beyond 100mm/s with larger, high-flow nozzles, leading to slippage and grinding. Feedback regarding the adjustment of tension has also raised concerns over the design, as accessing a set screw requires precision and can be a cumbersome task. Additionally, the extruder's temperature monitoring features seem to pose certain challenges, primarily due to rising temperatures of the stepper motor when tested at increased flow rates. In summary, the BIQU Nebula Extruder has received a mostly positive reception among users who appreciate its performance with specific filament types and easy installation but caution should be taken regarding speed capabilities and tension adjustments. **
