Anycubic Mega Zero 2

Posted on  by admin

I have my first 3D printer on the way and just researching how to go about upgrading the firmware when it arrives. On the AnyCubic site, I don't see the Zero 2.0 listed and after doing some research found a Marlin firmware that supports the Zero 2.0. My questions are:. Should I stick with the default firmware for now and upgrade later? If I do decide to upgrade, is there a way to backup the current firmware in case I have to revert?

About Anycubic

Does anyone have experience with the Marlin family of firmware? Are there any issues or caveats that I should be aware of? I've found several different instructions on how to update the firmware but is there a standard method that I should be following? How easy is it to brick the 3D printer by updating the firmware? Is there a roll back function of any sort or recovery? Sorry if these questions were asked in the past. I couldn't find much on the Mega Zero 2.0 in regards to this topic. Thanks for any support you can provide! This printer makes my 6th 3d printer that I own. I have had the pleasure of using many different brands of printers over the past two and a half years that I have been loving this hobby.

Anycubic Mega Zero 2.0 Overview

When I first started, I wish this printer would have been on the market.Assembly: Quick..easy..and took like 10 minutes. Great experience there. Also nice that it has a magnetically held in place drawer on the front for the allen wrenches, the nippers and other tools.Leveling: This is my first printer that has automatic bed leveling. I ran the leveling once and then went off and printed my first model.

I had enough confidence in this printer that I didn't do a benchy or a calibration cube.

I went and printed off something that I actually wanted to have. It came off the printer perfectly. The need to not have a scraper is fantastic. The flex plate (also my first printer with one) works flawlessly and it just makes me happy.Usage: I love how the textured build plate looks with this nice golden color and the texture it leaves on the bottom of the print is fantastic. See the attached photos.Lastly, the touch screen. This is the most responsive touch screen out of any of my printers. You don't have to press hard, you don't have to wait for any input delay, it It does exactly what you want it to do the moment you press it.I 100% recommend this printer to anyone who has either been in the hobby for a while or is new and just getting started.

Do you have an AnyCubic Mega Zero printer and want a stable firmware with the latest features?

Both V1 and V2 are supported. If you have added a heated bed to your V1 then flash it as a V2. Maybe you’re adding our EZABL kit to the machine. This is the download for you. Directions are below. We also recommend you download the Unified 2 STL pack as well. This contains EZABL mounts, Gantry leveling Blocks, Solid bed mounts, and Bed Level test files. Click here to go to the Unified 2 STL Pack download page. 1 –Printer Board Firmware Update. NOTE: These printers update over the USB cable from your PC to the printer.

Make sure to have a USB cable ready.

1.a – Download the firmware. 1.b – Extract the files to a folder on your computer. 1.c – Open the folder labeled “Firmware” in VSCode. 1.d – Open the Configuration.h file that is located under the “Marlin” folder on the left side of the VSCode screen. 1.e – In the Configuration.h file, uncomment (remove the 2 / in front of #define) the line for your printer version and any other options you are going to use in the firmware.

1.f – Click the ✓ at the bottom of VSCode to compile the firmware.

The firmware will compile. This may take 1-5 minutes depending on the speed of your computer and internet connection. 1.g – If the build succeeds plug in your printer to your computer with the USB cable. 1.h – Now click the arrow (right pointing) to upload to the printer board. Make sure ALL slicers or other programs that connect to your printer board are CLOSED before trying to upload to your printer.

Please note that on machines with multiple COM ports you may have to select the COM port manually.

Please see our VSCode COM port selection article to see how to do that. 1.i – The firmware will upload to the printer board over USB. DO NOT UNPLUG THE PRINTER OR RESET YOUR COMPUTER.Interrupting the flashing can “brick” your board and if this happens you will need to reflash the bootloader with a programmer (like an Arduino UNO) before you can flash again.

1.j – When the printer boots you will see the TH3D logo on your LCD. Make sure to reset your EEPROM on your printer after flashing any firmware. You can do this from your printer LCD or by sending a M502 followed by M500 with your favorite Gcode sender application.
