 Prepare 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.

Здравствуйте у меня KLP1 с экраном выходит вот такая ошибка :
Pin ‘PE11’ is not a valid pin name on mcu ‘mcu’

Once the underlying issue is corrected, use the “RESTART”
command to reload the config and restart the host software.
Printer is halted
Перезагрузка не помогает, ошибка остается.

Replacing the fan led to an error. Firmware KINGROON-KP 3S Pro V2 V2.4-20230818 no result.
mcu ‘MKS_THR’: Unable to connect
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.

“I also need a board replacement. I’ve tried applying all the firmware, but only the text saying ‘loading’ appears on the screen

I purchased kps3spro-v2 in May 2023 and have not been able to use it due to a breakdown.
failure symptoms
1. When you turn on the printer, the screen displays only Loading.

What to do
1. I tried to update the firmware, but the screen only shows loading.
> Firmware used armbian-KP3S Pro V2-20230322 (beta) (no screen):
https://1drv.ms/f/s!AmGcVrncIH3ZjBYprzZurjFIEcmr?e=c5gmTx
→ FYI
armbian-KP3S Pro V2-20230606 (latest) (with screen):
https://drive.google.com/file/d/1Bs7II2rqlCsdqx6EUUGfDOED4BwqQK0y/view?usp=sharing -- I can’t download this…

2. Ali Express sent me a motherboard and replaced it.
→ The menu screen is displayed normally on the screen.
→ The z-axis, automatic leveling, and shaper were performed normally.
→ If you select an output file during test printing, you should return to the main menu and operate it, but there is no change on the screen.
→ If you come out of the usb folder and enter again, a file called start printer is created. If you click this, there is no change on the screen. But no output…
→ So I installed the firmware 20230322 again, but the screen only shows loading.
Please tell me what action to take.
