Some of the benefits of jyers firmware are:
It has a much-improved, customizable on-screen user interface that lets you control various settings and options.
It supports automatic bed leveling with different types of probes, such as BL Touch, CR Touch, or manual mesh bed leveling.
It enables advanced features such as PID tuning, linear advance, filament runout sensor, power loss recovery, filament change, baby stepping, and more.
It allows you to use different mainboard versions, such as Creality V4.2.2 or Creality V4.2.7, which are common upgrades for Ender 3 V2.
Jyers firmware is easy to install and update, thanks to its pre-compiled configurations that cover various needs and preferences. You can choose from different versions depending on your mainboard, probe type, mesh size, etc.
What is CR Touch and how it can improve the printing quality and convenience
CR Touch is an automatic bed leveling sensor developed by Creality, which is similar to the popular BL Touch. It is a small device that attaches to the print head and measures the distance between the nozzle and the bed at different points. It then adjusts the Z offset during printing to compensate for any variations in bed height.
Some of the benefits of CR Touch are:
It eliminates the need for manual bed leveling, which can be tedious and inaccurate.
It improves the printing quality by ensuring a consistent first layer adhesion and avoiding nozzle crashes or air prints.
It saves time and filament by reducing the need for test prints or adjustments.
It works with any type of bed surface, such as glass, metal, or magnetic.
CR Touch is compatible with jyers firmware, which makes the firmware.bin file that you downloaded and renamed. Then, click Upload and wait for the firmware to be flashed to the mainboard.
After the firmware is flashed, you should see a confirmation message on the screen or in the console window. You can then remove the microSD card or disconnect the USB cable.

Step 6: Verify the installation was successful
To verify that the firmware installation was successful, you can do the following:
Check the firmware version on the screen by going to Info > About Printer. You should see the jyers firmware version and configuration name.
Check the firmware settings on the screen by going to Configuration > Advanced Settings. You should see the options for auto bed leveling, filament runout sensor, power loss recovery, etc.
Check the firmware functionality by performing a test print with auto bed leveling enabled. You should see the CR Touch probe moving and probing the bed before printing.
If everything works as expected, congratulations! You have successfully installed jyers firmware on your Ender 3 V2.
How to install CR Touch on Ender 3 V2
Installing CR Touch on Ender 3 V2 is not very difficult either, but it does require some steps and precautions. Here is a step-by-step guide on how to do it:
Step 1: Assemble the CR Touch kit and mount it on the printer
The first thing you need to do is to assemble the CR Touch kit and mount it on the printer. The kit consists of a CR Touch sensor, a metal bracket, a plastic cover, a cable, and some screws and nuts. You can follow for detailed instructions on how to do it.
The basic steps are:
Remove the Z endstop switch from the printer by unscrewing two screws and disconnecting the cable.
Attach the metal bracket to the X gantry using two screws and nuts.
Attach the CR Touch sensor to the metal bracket using two screws and nuts.
Attach the plastic cover to the metal bracket using two screws.
Connect the cable to the CR Touch sensor and route it along the X gantry cable.
Step 2: Connect the CR Touch wires to the mainboard
The next thing you need to do is to connect the CR Touch wires to the mainboard. The cable has two connectors: one with three wires (black, red, and yellow) and one with two wires (black and white). You need to connect them to the following:
Disconnect the Z endstop cable from the mainboard. You don't need it anymore since the CR Touch will act as the Z endstop.
Connect the three-wire connector (black, red, and yellow) to the dedicated 5-pin header on the mainboard. Make sure the black wire is on the left and the yellow wire is on the right.
Connect the two-wire connector (black and white) to the Z endstop port on the mainboard. Make sure the black wire is on the left and the white wire is on the right.
If you have a different mainboard version or a different probe type, you may need to connect the wires differently. You can refer to for more information.
Step 3: Adjust the Z offset and enable auto bed leveling in the firmware settings
The last thing you need to do is to adjust the Z offset and enable auto bed leveling in the firmware settings. The Z offset is the distance between the nozzle and the bed when the CR Touch triggers. You need to set it correctly to ensure a good first layer adhesion and avoid nozzle crashes or air prints.
To adjust the Z offset, you can follow these steps:
Go to Configuration > Probe Z Offset on the screen.
Use a piece of paper or a feeler gauge to measure the gap between the nozzle and the bed.
Use the knob to adjust the Z offset value until you feel a slight resistance when moving the paper or gauge.
Save the settings by going to Configuration > Store Settings.
To enable auto bed leveling, you can follow these steps:
Go to Configuration > Advanced Settings > ABL Settings on the screen.
Select Enable ABL and choose your preferred mesh size (3x3, 4x4, or 5x5).
Select Probe Bed and wait for the CR Touch to probe the bed at different points.
Select Save Mesh and wait for the mesh data to be saved.
Save the settings by going to Configuration > Store Settings.
