I recently purchased the Kingroon KP3S Pro V2 – I am working on a YouTube review of GPL OPEN SOURCE LICENSE legal compliance from 3D Printer vendors. The review will also discuss how well vendors provide general firmware update support.

1. Where can I get a firmware download for the KP3S Pro V2?

2. According to the GPL Licenses for Klipper and Armbian, the SOURCE CODE for modifications must be made freely available to the public on request.

There don’t seem to be any USA accessible repositories such as GitHub or Google Docs for Kingroon source code.

Please provide a link to the source code for the KPS3 Pro V2 firmware or information on how it can be obtained. This is needed so I can say on YouTube whether Kingroon is legally using the Open Source.

I have a Kingroon KP3S Pro V2 printer.
Inside the printer there is a KINGROON KP Cheetah V1.0 board, I want to backup my firmware, how can I do this?
I also want to update the firmware of my MCU GD32 F303, where can I get the new firmware and how to update?
Do you have instructions somewhere on how to do this?
Why is there no instruction anywhere specifically for this board: KINGROON KP Cheetah V1.0 for updating the MCU GD32 F303 firmware?

I noticed a comment below from a user saying that they were concerned that the page says to be careful to use the right firmware for your board, but then two of the download links point to the same file. From the facebook Kingroon group, several users say this is ok and that the F303 and F103 do indeed use the same firmware. I have the F303 and I downloaded the file (this is the file you get when you click DOWNLOAD in the F303 section), unzipped the files, placed them in the root directory of a FAT32 formatted sd card, inserted the card in my printer while it was powered off, powered the printer on.. and everything seemed to work. The screen gave a series of status updates about what the printer was doing, and then it seemed to work fine.

Добрый день дайте правильную прошивку для Kingroon KP3S Kingroon KP3 v1.3. и еще бы правильную прошивку для лазера для этой платы с контроллером GD32 F303

Добрый день, после прошивки на лазерную головку перемещение по оси Х стало наоборот. Вернул прошивку на простую но голова по отношению оси Х ведет так как будто на двигателе поменяны провода местами. Даешь команду влево а она едет на оборот. при команде домой упирается до упора в право. Что делать подскажите.

fui instalar o firmware do Laser da kp3 e agora esta tendo mal funcionamento no software original de impressão como faco pra deixar apenas o sofware de impressao

Does this version support changing color per layer?

Андрей - September 19, 2023

Здравствуйте. После прошивки стоковой прошивкой отсутствуют иконки меню. Что нужно сделать для восстановления?

Why Kingroon does not answer my question?
You suggested the firmware update because of the display problem but it doesn’t work.
By the type of the MCU, the firmware is different.
But when you click the firmware link, the destination is same and same file.
Maybe it is the matter but Kingroon does not answer.
What should I do?

I think BLtouch firmware must update. It doesn’t work at all.
