Check Minimum Requirements
Before you begin the installation process, it is important to make sure that your computer meets the minimum system requirements for Jyers.
These requirements include:
Windows 7 or later, macOS 10.8 or later, or Linux
A USB port
At least 1 GB of RAM
It is also important to ensure that your Ender 3 is properly set up and that the Marlin firmware is up-to-date.
The easiest way to check if your Marlin firmware is up-to-date is to connect your 3D printer to your computer and open the control software that you use to control the printer.
The version of the Marlin firmware that is installed on your printer will usually be displayed in the control software’s settings or “About” section.
You can then compare the version number of your Marlin firmware to the latest version number that is available on the Marlin website.
If your firmware is out of date, you can download the latest version from the Marlin website and follow the instructions for installing the firmware on your 3D printer.
This will ensure that the printer is functioning correctly and that Jyers will be able to communicate with the printer.
Check out the video below to see detailed information about how to check if your Marlin firmware is up-to-date.
Checking Your Motherboard
The next step before installing Jyers is checking the type of motherboard that you have in your Ender 3. This is because different versions of the Ender 3 may have different motherboards, and each motherboard will need a different version of the Jyers firmware.
You’ll need to tilt your printer to gain access to screws located on the motherboard cover. Then you’ll need to remove the screws with a 2.5mm Allen Key, which usually comes with the 3D printer but you can also get them on Amazon.

Download Jyers & Extract Files
The next step in installing Jyers is to download the software. You can download Jyers from the official website.
Download the version that corresponds to your motherboard, as checked in the previous section. For example, if your printer has a 4.2.7, then download the file “E3V2-Default-v4.2.7-v2.0.1.bin”.
Just click the file and it should download automatically. Once you have downloaded save it to a preferred location on your computer.
Copy the Jyers Files to the MicroSD Card
Next, insert the MicroSD card into your computer and copy the Jyers.bin file to the root folder of the card. You will need a MicroSD card that is at least 4GB in size, and it should be formatted in FAT32 format.
To format the MicroSD card, insert it into your computer, right-click on the card in the file explorer, and select “Format”.
In the format options, select “FAT32” as the file system and click “Start”. Make sure that the file is named “Jyers.bin” and that it is the only file in the root folder of the card.
Insert the MicroSD card into the Ender 3
With the Jyers files copied to the MicroSD card, you can insert the card into the Ender 3. Make sure that the printer is powered off before inserting the card.
The location of the MicroSD card slot may vary between the different models of Ender 3, including the Ender 3 V2, S1, and Pro. It is typically located near the mainboard, but the exact location can depend on the design of the printer.
Some printers may have the MicroSD card slot accessible from the front, while others may have it located on the side or the back of the printer. It is best to consult the manual for your specific printer model to locate the MicroSD card slot.
Once the card is inserted, you’re ready to enter bootloader mode.
Enter the Bootloader Mode
To install Jyers, you must enter the bootloader mode on the Ender 3. To enter the bootloader mode on the Ender 3, you’ll need to follow these steps:
Turn off the printer
Hold down the knob button on the Ender 3 while turning on the printer.
The printer will enter the bootloader mode, and the screen will display “Update Firmware”.
In bootloader mode, the printer is in a state that allows it to receive and install firmware updates. This is a necessary step in installing Jyers to your Ender 3.
By holding down the knob button while turning on the printer, you are telling the printer to enter this special mode. Once in bootloader mode, the printer is ready to receive and install the Jyers firmware update.
Select Jyers
With the printer in the bootloader mode, navigate to the “Update Firmware” option and select it.
The “Update Firmware” option can typically be found on the main menu or system settings of your Ender 3’s control interface.
Once you have entered the bootloader mode and navigated to this option, the printer will scan the connected MicroSD card for any available firmware updates. If the Jyers firmware is present on the card, it should be displayed as an option to select.
Upon selecting Jyers, the installation process will begin automatically. During this process, the firmware will be transferred from the MicroSD card to the printer’s internal memory.
This process can take several minutes, and you should not power off the printer or remove the MicroSD card until the installation is complete. Once the installation is complete, the printer will reboot and start up with the new firmware.
Complete the installation
The installation process may take several minutes to complete, depending on the speed of your printer. Once the installation is complete, the printer will restart, and Jyers will be installed and ready to use.
