Couldn't get my Ender 3 Pro to work.

I ended up wasting my time. I knew I wasn't expecting instructions but the QR code video was just awful. No sound and bad quality. Most of the installation was blocked by human hands just getting in the way. It's not my big problem, it's not as bad going without instructions as I've done before on another printer. My problem is that the brass bowden tube fitting is not attached to this frame in any way. To begin with, this armature was not included in the kit so I had to use the one that came…

Pros
  • STRONG AND DURABLE: All-metal aluminum alloy kit for self-assembly. Our MK8 extruder hot end includes all necessary screws and parts needed to directly replace your old original flimsy plastic Creality extruder.
Cons
  • New competitors appeared

Pass it on to the best additive manufacturing products

Bought for a brand new Ender 3 Pro. I set up the printer, typed it up, and printed on it with a standard plastic extruder for over a week. After making sure everything was working as expected, it was time to "update my extruder". And it was GREAT. within 2 days. then it started to slip, stick, etc. now, extruders aren't rocket science. It's a combination of the right tension with the right "teeth" for the material you're using. Which brings me to issue #1: although it has a spring, screws…

Pros
  • ADVANTAGES: The advantage of our extruder drive is that you have more pressure to push the filament into the printer nozzle, which improves the performance of the printers. Our extruder kits have an adjustable screw so you can adjust the extruder gear pressure as you need.
Cons
  • You could choose a newer model

A metal extruder produces much better quality prints than OEM plastic. but the inlet is in the wrong position

I bought this for my Ender 3 (also bought from Comgrow's Revain). I had serious problems with under-extrusion and followed various how-to videos that eventually ended with "Moving to an All Metal Extruder". When I took the stock extruder apart I found that the lever arm was cracked, so yeah that was my problem. This product arrived on time and is 'complete' - the included 'instructions' are a small card with a QR code. which will take you to a YouTube video. There's no real complaint. I…

Pros
  • UPDATE: A small pneumatic connector is supplied for the upgraded version. It is recommended to cut the PTFE tube before installation. Ideal replacement for Creality Ender 3 / Ender 3 Pro / Ender 5 / CR-10 / CR-10S 3D printer.
Cons
  • unreliable
