Many printing issues are actually caused by the extruder itself rather than all these other factors that you are coming across. It’s easy to underestimate the ability of your extruder settings and calibration to have a negative effect on prints. Additionally, Creality have added a new tensioner to the timing belt to make printing much smoother and fix the reported stability issues. Keep in mind that your leveling procedure varies whether your print bed is hot or cool, but a hot bed is most preferred. For the first print, I attempted one of the test prints included on the memory card. I used a third-party PLA filament; the print came out brittle and poorly cohesive. I tried again, this time using Ender filament, but try as I could, I couldn't get it to extrude. I expected that the extruder might be clogged, so I preheated the extruder to PLA melting temperature and took the long, very thin needle that Creality includes with the printer and poked it into the nozzle a few times. This cleared out the problem, and from then on the V2 extruded normally. In retrospect, I suspect the problem wasn't with the filament, but that the nozzle was set a little too close to the print bed, touching it in places so that filament wouldn't come out and causing the clog. I am activating those two features in the Configuration.h file of marlin firmware alongside with the LCD_BED_LEVELING setting.

Look towards adding a raft or a brim to your model if your supports are printed from the bed since the support itself doesn’t always have a good foundation.Even at higher speeds it mostly maintains high precision and quality, and honestly we pushed it way beyond the settings you should be using it at on a day-to-day, so a couple of the models that have small imperfects and gaps would have come out perfect if we’d ran the print on calmer settings. I also like to try a test print with a few skirts so I can actually see how well material is being extruded from the nozzle. Ender 3, Prusa, Anet & Other 3D Printer Nozzles Hitting Prints

An LCD set in portrait orientation is fastened to the printer's base. You control its non-touch screen with a knob below the screen. Please submit Feature Requests and Bug Reports to the Issue Queue. Support resources are also listed there. The goal is to be able to slide a piece of ordinary paper beneath the printer’s nozzle and the glass print bed. You want a little bit of resistance when you pull the paper: not a lot of resistance, or too little. You will be aiming to adjust the screws beneath the print bed plate until you are just barely able to feel some drag when you push/pull the sheet of paper through. Level the print bed on the Ender 3 v2 In any 3D printer over time belts tend to stretch slightly, making them a bit lose. Then, in sudden movements, they can slip and cause errors in the print. the new tightener knobs from Creality make this incredibly easy. Just twist them!There are some cases where rather than hit your actual model, your nozzle decides to only hit the supports. This can be a frustrating issue, but there are definitely ways to fix this problem. We started by assembling the 3D printer. One of the things you’ll notice off the bat is that the Ender-3 V2 Neo comes pre-installed. All you have to do is: This branch is for fixing bugs and integrating any new features for the duration of the Marlin 2.0.x life-cycle. With such nuanced similarities and differences between each Ender 3 model, it can be difficult to deduce which is the best Ender 3 printer for you. Manually leveling your bed is tedious. So if your print bed remains in one flat position for long, you won’t have to do it all the time. Full Metal Bowden Extruder

So we did part 1 of the upgrade, the display firmware. Let's finish part 2, the printer mainboard firmware. A heated printer bed helps with allowing the material to adhere to the baseplate and provides a stable platform for construction. Turning it lets you cycle through the panel's four main functions—Print, Prepare, Control, and Info—and pressing it takes you to a submenu, from which you can enter a command. From the Prepare menu, you can preheat filament (there are menu items for heating PLA and ABS) and disable the stepper motors, which allows you to manually move the extruder and build platform. Whenever you add new features, be sure to add tests to buildroot/tests and then run your tests locally, if possible. But of course you can also just open visual studio code and then use the open folder menu from the side bar to open that folder by locating it on your computer.I would go around your 3D printer and tighten up the screws as it can easily translate to better print quality. I’ll explain all the differences to help you decide which Ender 3 is best for you.
