Official Creality Ender 3 Direct Drive Extruder Kit, Comes with 42-40 Stepper Motor Hotend Kit, Support Flexible TPU Filament, BL Touch, Compatible with Ender 3 Pro/Ender 3 V2

I've been trying to print a pretty large object (~19 hour print) on my Ender 3 Pro for a couple of weeks but it keeps failing. You can see in the first photo that there are defects at various levels before the print actually failed with filament failing to come out of the printer after about 3 hours. It turns out that this was due to under extrusion. I was planning to replace the extruder arm as it had a hairline crack, but for a little extra money I decided to upgrade to this direct drive extruder. The item printed *perfectly* the very first time as you can see in the second photo. Installation was pretty straightforward but the instructions that came with the device were severely lacking - all I received was the circuit board layout (visible in photo #3). Fortunately I ordered the product for myself and was aware that there was a good video on this product listing - I might have been a little lost had I received this as a gift. To complicate installation a little I, like many, have a non-Creality board in my Ender. I took photographs of what was currently plugged in where, and was able to attach the new hot end to the same ports on the motherboard. Everything else was smooth sailing and the video in this listing accurately depicts the installation process. The hot end worked first time and I am delighted to final complete this 19 hour print. If you're having any printing issues I highly recommend this upgrade!

It worked as promised and improved my 3d printing pleasure, once I figured out how to install it.

Muy fácil de instalar, solo sigue los pasos que vienen en la página de Amazon

Works perfectly for printing TPU, which was the main reason for the purchase. However, as stated by another reviewer, the screw for the thermistor was screwed on too tightly causing an error that won't allow you to print anything at all. Luckily I had seen that review before making the purchase so I knew it was a potential problem to be aware of - with an easy fix - I just had to loosen the screw a bit. This wouldn't be an issue at all if the product contained better instructions explaining this to the user - I'm sure this single issue has caused the product to be needlessly returned many times. Due to this, I'm rating the product only 4 stars. Please include better instructions to save people time and from any headaches/frustration and this product would be an EASY 5 out of 5 stars. Aside from that minor setback: considering the amazing price for what you get, plus the improvement in print quality (and most importantly frustration-free TPU printing,) I HIGHLY recommend this product!
