Redrex Upgraded Aluminum Bowden Extruder with 40 Teeth MK8 Drive Gear for Creality CR-10 Series Ender 3 and Other Reprap Prusa 3D Printers [Right Hand]

I have one on an Ender 3 Pro and another on a Monoprice Mini Delta, and they're both fantastic. Extrusion is more dependable, and I never have to worry about filament rubbing against the plastic feed parts, ruining a multi-part assembly. a print for the day The installation was simple and the replacement was a direct bolt-on. I kept using the stock gear in both cases to keep my stepper calibrations the same. After assembly, I discovered that the spring was too loose on the retaining screws, so I replaced the button head screws with socket head screws and screwed them in from the inside, ensuring that the spring sits over the screw head and has no room to shift. br>br>However, I did notice that the included spring has a lot of force, and with too many retractions over the same spot, my filament was smashed too much to travel down a capricorn bowden tube. If your prints require a lot of retraction, I recommend using a slightly weaker spring, such as the stock one. Within Cura, I was able to solve the smashing problem by restricting retractions to the same filament.

Several months ago, while moving, I broke the extruder on a custom 3D printer. Because there was no way to print a new one, this was a cheap and effective solution. This extruder will most likely be used again. Because I wouldn't be able to move the extruder after assembly if I used the included bracket, I used one from OpenBuilds that I already had on hand. br>br>If you're wondering how many steps per mm there are, I discovered that there are 98. When using a RAMPS 1, 8 performs exceptionally well. The Marlin firmware is running on four boards with 1/16th stepping.

Flex filaments are a breeze to work with.

This was purchased to use with my Monoprice Mini Delta 3D Printer. A jammed feed tube caused the original part to break. There has never been a time when I have regretted upgrading or repairing my home. Installing it was a breeze, and it gave me a more secure feeling. Overall, this is a must-have upgrade for some 3D printers, though my second printer does not use one.

br>br>1. This product has two flaws. br>br>2. It doesn't feed filament in a consistent manner. It makes a popping noise but doesn't move the filament at all. It's possible that the cause is a misalignment of the roller and filament. In addition, the equipment appears to be of low quality. 2. br>br>1. br>br>br>br>br>br When threading the filament through the extruder, it gets hung up after the roller and then where it goes into the bowden tube, which is incorrect. Getting the extruder threaded requires a lot of fiddling around. Is this the root of the first problem? br>br>In any case, this product did not perform as expected. I'm going to experiment with a dual gear extruder to see how much better it is.

it appears to be excellent For a few weeks, everything was fine, but then I noticed some layers weren't printing. The extruder was turning and the gear was turning, but the filament was not feeding. This was only happening on occasion. I discovered that the'release' lever was stuck, and that the feedstock was not being properly pressed. I'm used to working with mechanical devices and know how to adjust them. br>After a few hours of fiddling with it, I replaced it with the old one. There will be no further tying. br>I suppose not everyone can be a winner. We're all relying on you, so good luck.

The Ender-branded plastic housing is included with the Ender-branded Ender-branded Ender-branded Ender-branded 3 is a bad design, especially considering how the filament should be mounted. The plastic-making process is aided by the filament's sharp 90-degree turn before entering the extruder. Plastic friction carved a groove in the tension arm, causing filament alignment issues. This anodized aluminum helped me get my printer back up and running again; it's a fantastic product.

For my ender 3, it's perfect. The only issue I had was that I couldn't fully tighten the hinge screw, but it seemed to hold. The counter bore should, in my opinion, be deeper, and the spacer small OD should be longer. I've been using it for about a month now and have had no issues.
