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.

Worked perfectly. This hot end needed a lot of tuning to get fully functional with my Ender 3 Pro. I had some very poor layer quality and after changing first layer settings, adjusting rollers, removing and remounting hotend, and adjusting many many other settings i was able to get the hot end working perfectly. I went into this knowing i was going to have to tune things heavily. I have printed PLA, ABS, and PA6-CF with no issues. Everything is working perfectly and I am very very satisfied with the purchase. Even with the troubleshooting and adjustments i had to do over 3-4 days, this still gets 5 stars from me.

Works great and is well made. Installation was simple following MS instructions. One suggestion if I may. If its possible to put some sort of index mark on the face of the brass adjustment screw. I think it would be help when backing off the pressure when printing flexibles.
