The nozzle will repeat the square motion several times, building up the layers and giving you a chance to test and recalibrate (by pausing the print and turning the adjustment knobs on the bottom) as you go. The nozzle will repeat the square motion several times That is because the Ender 3 v2's display has it's own firmware and needs to be in sync with the printer firmware. Note: the code will halt the printer head at each test location. Once you have tested and adjusted at a stopping point, press down the Ender’s control knob. That will tell the code that you’re done leveling that point, so it can move onto the next. Level the print bed on the Ender 3 v2

This file tests your Ender 3 V2’s Z-axis, X-axis, and Y-axis to ensure that there are no hangups, grinding issues, or binding when the extruder is moving. It will run your Ender 3 through its paces, but this only takes a few minutes to do its thing. 4 – Level the print bed on the Ender 3 V2 Level the print bed on the Ender 3 V2 New feature ideas are always welcome and a great way to improve the firmware. There are three ways you can suggest a feature. If you have a general idea, but would like some community input on the feature, open up a discussion where everyone can chime in. If you have a concrete idea you think would benefit the firmware, you can create a feature request in the issus tab on GitHub. If you have a solid idea and have the ability to implement it yourself, implement it in your own fork and create a pull request to the main branch. Marlin 3D Printer Firmware To prepare your PLA spool, carefully snip the end at an angle. This helps you feed it into the tube that leads to the nozzle head. If your PLA line is bent or kinked, I recommend just snipping off the bent section, as this can cause issues with the print. If it’s a mild bit of bending, you might be able to straighten it out, however. 7 – Hang your PLA on the Ender 3 V2 Hang your PLA on the Ender 3 V2 Similarly, the Ender 3 V2 outstrips its sister models in terms of its user interface. The introduction of the new 4.9-inch color screen makes operating the printer much easier. There is also something to be said for the more modern-looking casing for the screen as well. Value for MoneyA lot of people get this wrong and wonder why their firmware seems to build for the wrong printer and why they don't see the right environments showing up. An important thing to realize about the Ender-3 V2 is that it comes as a kit. Creality doesn't sell a pre-assembled version. During setup, you bolt together or otherwise connect the parts mentioned above. Building the V2 is more involved than constructing the Original Prusa Mini—for which you bolt the Y-axis assembly to the base, attach the LCD screen and spool holder, and connect some cables, and then you're good to go. Assembling the V2 was akin to the build process for the AnyCubic Vyper, taking several hours for the basic construction and a few more in troubleshooting.

If your extruder is too low, you’ll have to take your extruder apart, then reseat it properly. The case here is that the extruder might not be securely fitted inside how it should be. I would search a video tutorial on your specific 3D printer and follow how the extruder was put in. Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork. So, we printed the halloween mini-pumpkin on the left at 0.1 mm, and the one on the right at 0.2 mm. This is what they looked like. The original Ender 3 received complaints about the overall stability of the printer, with a wobbly baseplate and shuddering arms that compromised the quality of the part when produced.Although it gets the job done, we still feel like Creality can do better with this knob. Most 3D printers in this price range, like the Anycubic Kobra, now use touchscreens. Other Ender-3 V2 Neo Features Build Volume

This branch is for fixing bugs and integrating any new features for the duration of the Marlin 2.0.x life-cycle. 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. This allows you to very easily load, unload, push or pull filament manually. you can simply grab the knob and twist: a simple and elegant manual solution. The user interface has also been updated, with a new detachable color screen which makes controlling the device much easier and clearer. To build Marlin 2.0 you'll need Arduino IDE 1.8.8 or newer or PlatformIO. We've posted detailed instructions on Building Marlin with Arduino and Building Marlin with PlatformIO for ReArm (which applies well to other 32-bit boards). Hardware Abstraction Layer (HAL)I am activating those two features in the Configuration.h file of marlin firmware alongside with the LCD_BED_LEVELING setting. The Ender 3 is certainly the best value for money in the series, and maybe in the entire industry altogether. You can compare it to the premium version in our Ender 3 vs Ender 5 guide.
