I have been rebuilding my Ender 3 for a couple of years now so I decided to go ahead and get "the ultimate upgrade" and pull the trigger on the Microswiss NG Direct Drive Extruder. In all honesty, it was a breeze to install, however, the filament keeps getting stuck between the heat brake and the heat block/nozzle. It is a nightmare! I can print for 4 hours very smoothly and out of the sudden, this thing gets clogged. I have tried too many options (bed leveling, retraction settings, temperature, etc) and wasted too many hours printing and trying to get this figured out. Definitely not worth it.

For the life of me, I can't get this thing to work right. Nothing prints well with it. No PLA, not PETG, not ASA, not PA6.

Not to mention, the CR/BL touch mount that is provided is CLEARLY printed in PLA. While I attempted to run some ASA test prints, the sensor mount drooped and was dragging my BL touch all over the poorly printed parts.

Complete horseshiite.

Years ago I built several Reprap printers that had geared extruders. They worked ok but as anyone knows they had a lot of issues. So tweaking print settings and hardware isn't a new rodeo for me. As my old printers became obsolete, I acquired two Ender 3 Pro's and have always been frustrated with a variety of print issues, particularly with the bowden extruder stepper missing steps, fooling around with retraction settings, etc. Having friends now enjoying their Bambu trouble-free printing, I thought it was worth a try to upgrade to the direct-drive NG extruder as a last-ditch effort before moving on. Glad I did. The NG upgrade completely transformed the first Ender I upgraded. Finally have gotten my first upgraded Ender to be hassle-free. Will be upgrading my other bed-slingers.

Product was well-packaged with everything I needed. Instructions were clear, and I was back to printing in no time!

Everything has been working great, I had some problems because I didn't get the neo version, but they sent me the extra pieces I need for free, so It all worked out.
