  1. 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.

Do you have the KLP1 230 files?? How can we update the klipper firmware? Any Help will be deeply appreciate

Tygo - May 27, 2024

This page has been an absolute lifesaver for me, having sent my printer into a bootloop on the weekend.
This guide should be referenced in the user manual imo, cause I suspect I won’t be the only one with this issue ealy on.

Thanks for sending a well thought out printer and toolkit.

Haber tengo varios problemas he comprado la impresora de segunda mano y me da error con la autocarga de filamento como que no reconoce que hay cable y varios problemas más como algunos gcode que no reconoce la maquina. Puede ser que el antiguo usuario borrará algo y por esos estos fallos? Tendría que hacer un flaseo de estos?

Hi, I have updated the memory to KINGROON-KP3S Pro V2 V2.4-20230818.

I have the same message on start Pin ‘PE11’ is not a valid pin name on mcu ‘mcu’ and the screen shows Loading…

Give me any solution please…

Marzio - December 6, 2023

Hi, I’m using KINGROON-KP 3S Pro V2 V2.4-20230818 and performing a print it seems retraction is not enable at firmware level: for all G10 and G11 commands are marked as unknown.
Is it something intentional because of construction problems or is it an oversight/you are plan to release soon?
