Flsun speederpad & btt manta m8p v2 installation

General Discussion
1

Basic Information: I have a flsun v400 device and its card burned out recently. I also have a BTT Manta M8P v2 card. I installed it in my device, but I couldn’t install the MCU card with the speederpad. The speederpad has a clipper installed. I just want to connect it to the card and check it. I use the USB port on the speederpad. I connect the other end of the cable to the Type-C card. pi@speeder-pad:~$ ls /dev/serial/by-id/
usb-1a86_USB_Serial-if00-port0
It comes up like this, but it doesn’t work. How can I do this? Please help.

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed

Btw: Creality Sonic Pad and Alternatives

Generally, if you don’t know how to install a clean system and Klipper on your pad, I’m not sure it is usable or that we can help you with it.

That only means there is a USB2UART chip in between. I’m not sure where or what this means.

Generally, on old boards, there is no real USB 2 MCU connection.
Instead, there is CH341 USB2SERIAL converter.
So, if you try to connect to this type of motherboard, under the hood, it would connect like
Klippy host → USB → CH341 → UART → MCU.
Where on normal motherboards, it is:
Klippy host → USB → MCU.
Or
Klippy host → UART → MCU.

So, to flash that motherboard, the SD card is used, and mcu should be configured for UART connection.

Hope that explains something.
