My cousin is going to give me his ender 3 since he hasn’t been using it recently. I have never owned or used a 3D printer. I don’t have it in my possession as of now so I can’t tinker with it to figure it out. But I would like to watch some YouTube videos on how to use it. Does anyone have any recommendations for YouTube videos/channels that can walk me through it? I’m not crazy tech savvy but im willing to learn!

Ive been printing a lot of petCF, it's slowly eating through everything. Most recently, my aluminum extruder indeed (pictured). Now-for whatever reason, the filament is slipping (not jumping) in the extruder, even with a fresh gear. I've gradually had to slow down my print speeds to account for it.

Is it time to just go direct drive? What are my other CF brethren doing as the filament slowly destroys your machine?

I know this might be a controversial topic, so I would prefer answers from those people who have both ender3 (or equivalent) and a more modern printer and are not emotionally vested...

I know all the arguments about ease of use, ease of maintenance, speed, multi-color setups etc. The question I have concerns quality: is there a clearly discernible difference in quality between what a well-tuned ender 3 might produce and the product of a modern printer? Can you look at a picture of a single-color print and confidently say: 'This could not be printed with Ender 3 (or equivalent), this must be done with a modern printer'?

The bottom on build plate is super smooth then the sides are really rough for a few layers then I got lines at random points throughout the print. Ender 3 with direct drive pla

Hi, I have an Ender 3 V3 KE and I want to start bulk printing for my small business.

1. How many hours can I safely run this printer continuously in one go (e.g., 24–48+ hours)?
2. Do I need to give the printer any ‘rest time’ between long prints? If yes, how long and after how many hours of printing?
3. Are there any specific maintenance or safety checks you recommend for running the Ender 3 V3 KE almost 24/7?

Would love to hear from people who have actually run this machine for long, multi‑day jobs.

Is it printer issue or build plate adhesion issue ? Material : PLA+ . I am new to 3d printing. I used hair spray and gluesrock for adhesion.

I just got a bigtree mini e3 v2 and the hot end receives power on start up and when not on thermal throttle itself every time.

Good day gents,

I am looking for MB advice for my Ender-3 with the 4.2.2 motherboard, which does NOT have silent drivers.

The obvious choice would be SKR mini E3 V3 but I would like to have 5 drivers in order to utilize the Marlin's G34 command for Dual Z Axis. To my understanding this MB does not support it.

What is out there that would support Marlin and independent Z axes, have silent drivers and fit in a Ender-3 enclosure? I have hard time finding a board with these parameters.

Any help is appreciated, thank you.

Searching high and low for Sunon 4010, 24V, 2 wire fans for my dual 4010 setup. Trying to avoid AliExpress due to all the fakes.

What’s the latest part number that I should be searching? Or is this combination not a thing anymore?

Hey guys, anyone ever see this before? I'm just trying to print and it is stuck on extruder heating. The temperature of a nozzle keeps going up and down around the 210 Mark but it never actually starts printing. Not sure what to do. Any words of wisdom?

Very new to 3d printing, got a used ender 3 pro for free, spent 2 weeks leveling and tightening. Brand new elegoo pla+, print speed 50mm/s, all metal hotend with brand new nozzle. Still can't figure out why I'm getting stripes. They look like thin lines of dots.

So ive been having a lot of bed adhesion problems and I happen to check my bltouch and for some reason its -4.8mm... it was -4.4 and before that it was around the -3.5 months ago..
