Descrition:
1: For the Stepper Motor Mounting Bracket, it is not guaranteed that all customers can use it.
If your printer has its own motor mounting bracket, you only need to use your own.
2: The internal filament feeding hole is small and precise. To ensure that the filament can be inserted smoothly,
you can screw the spring to the loosest position firstly and then tighten it when the filament is inserted.
3:The reference value of E-step is 385. Do an Estep calibration to get exact estep that fits your printer
4: Note:For Mega/Vyper users,Please make sure to：
Invert the stepper motor in firmware or by swapping stepper cables to changing the direction of rotation.

Got this to replace my Geeetech Mizar S dual extruder. Worked great for the limited time I used it.

This doesn’t last very long. Stops feeding the filament after a few ( less than 4 day long ) printsI changed plastic manufacturers. It’s the extruder

These work as required. Seems to be a good extruder. Easy to install. Time will tell how long they last.

I have an Ender 3 max Neo printer which it said right in the description that it was compatible with. I was frustrated when the motor shaft was too short even though it said it would work with the Ender 3 max Neo. I had to buy a new stepper motor and got that set up. I then realized my filament sensor was no longer level with the extruded and so I had to raise the filament sensor up a few more inches to make it work again. Bottom line, make sure everything will fit and work before going down a rabbit hole or more things you have to do to get it to work.Now that I have everything setup the dual extruded works great, just a pain to get it going.

Works perfectly with no modification at all. I bought one about 2 years ago from another vendor and had to modify it. This one just worked out of the box and feels great!

Perfect fit and an improvement over the OEM part. Would have given 5 stars if instructions were included. I had to refer to pictures on Amazon listing. In the end it is a good part.

The stock extruder motor can't be used with this product for the Ender 3 Pro V2. The shaft is too short.

I have had my ender 3 pro for several years and heard of the need for a metal extruder, seeing some worn plastic on my old one I started looking and found this one.it was fufilled by amazon so it was here the next day which is impressive in COVID-19 spring 2020, it came nicely packaged except no instructions and the pictures currently available in the product page also do not list where all the parts go, I finally through some google searching has found that this is a clone of a bondtech extruder, and was able to locate where the parts I had not put in during my first assembly go.the biggest con so far is finish, the drilled holes for the filament path could be chamfered so it does not scrape and cause plastic dust during the prints, I may disassemble at some point and see if I can round them out myself, otherwise, once I reset esteps, the prints seem to come out very well.
