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!

Item arrived quickly, was well packaged in a padded box, and was fully assembled. Even came with a tool kit. Installation was simple, but understand the installation instructions are for wire hookup only. There are plenty of online tutorials on how to install. This is a plug and play item. No fancy coding skills necessary. The only issue I had (as others have had and reviewed) was the temp sensor was over tightened and shorted the thermistor. This shows an “over-temp” when you first go to use it. Back the screw off slightly and good to go. Manually leveled my bed and have been printing for 3 days now with zero issue. Printed nylon at 260°c with no issues. As for the other reviews stating the rollers were too tight, mine weren’t. I literally removed the old end and installed this one without any adjustments necessary. Rollers were correctly set. For the price of a new hot end that is nylon capable, this was well worth the money I spent. Couldn’t buy a decent all metal hotend for this price. It even uses standard nozzles (which I have a ton of). And it’s a direct bolt on. 5 stars from me, even with the thermistor screw issue. Will be buying more for my other Ender 3’s.

Tengo la ender 3 normal, llevo una semana que cambie a este estrusor, la instalacion es facil aunque de un inicio las ruedas quedaron algo flojas y el estrusor no quedaba bien ajustado al riel, despues de investigar un poco vi que era cosa de ajustar la tuerca excentrica de los rodamientos y esto soluciono el problema, he estado imprimiendo piezas diario durante una semana cambiando distintas marcas de filamentos, todos en PETG y hasta ahora no ha habido ningun atasco ni understruding, incluso la calidad de las impresiones con mejores que con el estrusor anterior, sin duda una magnifica mejora, ahora voy a intentar con TPU a ver que tal se comporta.Despues de unas semanas empezo a dar problemas de atasco como el estrusor original
