    The Best Extruder Ever!

    I know my title is a big claim and its true. I've been researching which metal hotend extruder to get for a while and when I saw this and they offered a linear rail edition on this new design, I was excited.

    The instructions that come with this product provide all the necessary information to get this installed quickly and easily. I was upgrading from a stock extruder on an Ender 3 V2 with a linear rail kit and installation was a breeze. You'll need to check to make sure your existing kit can be used.

    One suggestions which might help future users to know. The aluminum plate which attaches to the linear rail has an extra two holes on the left side of the plate and I believe that is for a BL Touch mounting kit specifically. I have an Creality CL touch and the mounting kit is not compatible. Maybe there's an opportunity to select the plate based on the user equipment. I just designed and printed the part I needed, works perfectly.

    Thanks for providing the gcode to get the esteps correct. I'm using Jyers firmware 2.0.1 which allows you to enter the esteps without needing to run the gcode on the micro USB.

    This product works so well I'll be buying more for my fleet of printers soon.

    Thanks for making a fantastic product!

    The box made for a quick dog chew toy as well.

    Well Made

    This is my second NG.
    No problems. Solid machinery.
