Review on WANHAO FlashForge Builder Hotend Nozzle by Steve Cooper

It was easy to install if you take your time. I learned the hard way that this doesn't work with stock injectors. After installation, everything needs to be recalibrated, especially temperatures. The instructions state that PLA requires a much higher temperature. I've found that temperatures between 10 and 40 degrees Celsius give excellent results, even with poor quality yarns. I also found that my firmware does not allow operation at higher temperatures. A quick update solved this problem. The pictures show the temperature calibration rod made of high quality ABS plastic. Prior to the installation of this all-metal hot end, this thread had a habit of separating layers. I also turned my slicing engine into an idea generator to use different temperatures and fan settings depending on the build height. Highly recommended.
