Creality Upgraded Ender 3 v2 Ender 3 CR-10 3D Printer All Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Ender 3 Pro/Ender 5/ CR-10 Series

I would strongly advise double-checking whether the stepper motor has a pressed gear or one that is held in place by screws. I have an Ender 3 Pro (2021), which has a newer stepper motor with a pressed gear, according to the manual. You can tell if the rod is nearly flush with the gear or if it has passed the gear if the rod is almost flush with it. So, if you want to use an extruder knob, you're out of luck. Next, the seller failed to mention that removing the pressed gear would necessitate the use of additional tools, such as a pinion gear remover tool. I removed it with pliers and a spring nail punch, which was not the best method and may have caused damage, but you're stuck with either buying a remover tool or replacing the stepper motor. The center rod is shorter on this stepper motor because it is newer. If you want the filament to be centered between the gear and the bearing, the stepper gear must be raised higher than usual, as shown in the image. I'm also not sure if I got a used one or if there was a problem with the quality control because my spring handle was a little scuffed around the edges.

Extrusion issues: at first, lines in the prints appeared to be missing material. PETG's next problem was that he couldn't get the spool off the spool. Finally, PLA refused to pull without a lot of manual help. As a result, I placed an order for this kit and began working on it the same evening it arrived. br>br>The instructions were simple; the parts list was not in English, but the exploded diagram was extremely helpful; my only issue was removing the extruder gear from the motor shaft-- Vise Grips, as well as a C-, were required. To remove the press fit gear, I used a clamp, a hammer, a 10d nail, and a lot of hope. Everything else was simple. br>br>After about an hour of work, I was printing with PLA with no problems; I'll be testing PETG later in the day, but I expect similar results.

The printer feeder broke on Saturday night while printing a part that was 75% complete. During troubleshooting, it was discovered that the tension arm had broken. Although there were many similar products, another buyer used this one for Ender 3v2. I took a shot at it and failed miserably. I only had to replace the broken part, and the printer was back in hobby production mode in no time. The original part lasted for a few months of almost daily printing for a total of 9 hours. If you are a new owner, you should upgrade this when you purchase your printing because you do not want it to break while printing a large model. Later, I'll put in the remaining components. However, for the time being, only the arm required replacement. The arm was installed in under 5 minutes. Cyber Monday sale was used to make this purchase.

Because of the numerous failures in the stock plastic parts, I purchased this after the nut insert on my stock extruder for the Bowden tube came apart. This setup should come as stock. The new parts did cause me one minor issue. The new extruder's idler wheel was not properly centered on the filament, resulting in some skipping. I was able to use the original idler wheel to replace it, and it worked perfectly.

Take a photo of the OEM part before installing the new one so you have a reference. br>br>I believe this part allows for more uniform flow rates in general, based on my calibration of the e steps. br>br>Because my Ender 3 pro had a compression fit brass gear, I decided to leave it alone and keep the screw on variant as a backup in case I ever needed to replace the stepper.

My Ender 3 was having trouble moving the filament in a consistent manner. To keep up with the prints, I had to keep increasing the filament speed. It simply stopped feeding at a certain point. The plastic tensioner arm had been broken, as it turned out. This resolved the issue, and I should no longer have to worry about it breaking. I had to reduce the filament speed slightly from stock, but the prints are still very smooth and consistent.

On a V3 edition of the Ender 3, I could see them having this stock. This is so much better than the stock plastic assembly that it almost appears shabby when it arrives. for- It dropped on and has been working like a champ for me ever since. 1 on your extruder settings, no need to recalibrate for the hob gear, etc.

It's a fantastic product at a low price. The grey model is more of a dark gunmetal grey than the bright almost silver one in the pictures, not that I mind; in fact, I find it much more appealing; the lever is much smoother and, unlike the plastic ones, can be tightened while still moving freely. Because the bearing that came with mine was defective, I simply replaced it with the original. There's no reason to pass it up at this price.
