Flashforge Dreamer with NF Crazy hotend 

It worked fine during the time it was installed, but I ultimately returned the hotend back to its factory configuration. I went through about 1/2 kg of filament trying to get print quality better that I could with the original setup, but the results were the same. The only real upside is the speed at which the hotend heats up, but I was unwilling to trade that for the increase in noise level due to the smaller cooling fan (linked below) I used. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AbIA4V4omek.html

@@aphex4000 the purpose of the hotend is to be able to print faster/at higher flow rates

@@williamluong7743 yep, I completely agree! However, I think a full Bowden extruder conversion would be needed on this particular printer to fully benefit from this hotend. There is just so much weight on the carriage that changing directions at high speeds (even with tuning of accel/decel settings) causes too much vibration. Because of this, the only other benefit I looked for was an improvement in quality, which just isn't going to happen. 😕
