dear KINGROON Office
your firmware for MCU GD32 F303 dont work it stuck on blac screen and after restart it stuck on booting screen is there any way to make my printer working?
@Juan Tomas
Which model is the main control chip of your motherboard? Brush the corresponding firmware will be able to, the program inside or different.
@Luke
Is there something wrong with the machine? The machine does not replace the motherboard, do not replace the extrusion motor, is not necessary to update the firmware!!!
Kingroon KP3S 3.0 with MCU GD32 F303 firmware goes to the wrong link (Kingroon KP3S 3.0 with MCU STM32 F407), I did not notice and now my printer’s board may be potentially bricked.
Hi, I have tested the firmware for my kp3s v3.0 and it stays on tft updating 100%. It does not pass and the firm ok does not remain. I have the board with the gd32f303 and as I see the link is the same firmware as that of the STM32 F407 board
