How to Falsh the EMMC Chip on Kingroon KP3S Pro V2 and KLP1

The Kingroon KP3S Pro V2 and KLP1 3D printers actually give you full SSH access to the system, some of you have already find that out. If any system failure happens and you are not able to fix it, or you are just doing some test, this article will show you how to flash the EMMC to fix it.Before start, we must warn you, messing up with the system or flashing EMMC have some risks that may cause system failure or warranty loss.

What is EMMC?

eMMC stands for "embedded MultiMediaCard." It's a type of flash storage. In the context of 3D printers, eMMC typically refers to a type of onboard storage used for storing firmware, settings, and other essential data required for the operation of the printer. Many 3D printers utilize eMMC or similar embedded storage solutions to store the firmware that controls the printer's functions, such as motion control, heating, and extrusion.

Having eMMC onboard allows 3D printers to boot quickly and store firmware updates or configurations without relying on external storage devices. It also helps ensure the reliability and stability of the printer's operation by securely storing critical data.eMMC storage in 3D printers may vary in capacity depending on the specific model and manufacturer's design choices. It's typically soldered onto the printer's main control board and accessed directly by the printer's microcontroller.Overall, eMMC storage plays a crucial role in the functionality and performance of 3D printers by providing a reliable and efficient means of storing essential firmware and data.

Prepare

1. Tools you need
Before starting, you need to get a SD card reader. Try get a good one with high performance, or it may not able to white the EMMC moudle.

3. Software you need
Go to https://etcher.balena.io/ and download balenaEtcher. If you are Windows user who’s already get used to Win32DiskImager, it is also fine.

Prepare the EMMC Module

1. Get the EMMC module
Remove the bottom cover of the KINGROON KP3S Pro V2 printer, then you are able to see the EMMC module. Loose the screws on it, remove the module carefully.

2. Get everything connected
Connect the module to the EMMC adapter and SD card reader, as the photo shows. Be careful with the directions. Then you are ready for the next step.

Flash the EMMC Module

1.Setup balenaEtcher
Connect the SD card reader to your PC or Mac, you should be able to see a disk named “boot”, that’s the EMMC module. If not, please check the connection and make sure the direction is correct.

Open the balenaEtcher, choose the image file you just downloaded, and click flash. Please double check the disk you choose, in case you lost any data.

If the disk disconnected in the middle or the flash failed, please use a different SD card reader.

Once the flashing finished, you are all set. Just put everything back, reboot your printer, and enjoy the 3D printing.
