The stock extruder on my ender 5 pro started slipping... after tearing it down and rebuilding time and again I finally took the leap and bought this direct drive from Micro Swiss. It was fairly easy to install and has performed flawlessly from the first print. It has not had any issues whatsoever. NO FAILED PRINTS! I'm excited to try some different filaments, as I'm only using PETG and PLA. I plan to get a larger format printer in the future.. and the first thing I'm going to do with it is install a direct drive extruder from Micro Swiss. You can't go wrong with this purchase!

I have the Ender 5 Pro and found that I mostly print functional parts out of PETG that are more heat and weather tolerant. The stock Bowden setup doesn't print PETG well. The nozzle oozes so much and no amount of retraction eliminates it. This direct drive upgrade is a must have for anyone wanting to print high quality high temperature filaments. I'm absolutely blown away by how this upgrade improved my print quality. The stringing is very minimal or non-existent. The filament is very easy to load into the extruder as well.

The metal components and construction are fabulous. Using the entire mounting bracket as both a heat break and a heatsink for the stepper motor is genius and works flawlessly. What's disappointing is the choice of plastic for the fan shroud and BL touch bracket. I assumed that because this is a premium full metal hot end, the designers had higher-temperature materials in mind. I used the hot end to print PC max with a build plate temp of 110C(230F) in an enclosure that reached around 45C(113F). It did this very well until the included BL touch bracket melted plunging the sensor into the model bending it and ruining the print. The entire fan shroud also began to sag and drag across the top of the model. Ive never had trouble printing PC on my other printers with ABS components even with build plate temperatures exceeding 145C. I will have to jerry-rig a temporary cooling setup while I print a new shroud out of higher-quality material.

this is with out a doubt the best product I have added to my printer, please make sure you change the extention to the motor if you have one of the first DD all metal hot ends from micro swiss, or you could damage the board.

I loved it so much for my Ender 5 plus, I bought a second one for my other printer
