cheetah_v3.0's Issues
Marlin firmware support
In description it says that this board support marlin 2.0 but neither marlin repository nor this one contains configuration for this board. Is there any instructions on building marlin firmware for this board?
Random lost communication via usb
When I setup connection via USB->Rpi 4 it can disconnect random midprint. But when I use UART, everything is working ok. I have tried different usb cables, does not help. It also disconnects until I press reset button on the board. After I press reset it connects normal. So I don't think it is cable issue.
Unable to setup CAN network
Attempted to setup the CAN network, but I am unable to establish communication. The Pi doesn't recognize a can0 network. The BigTreeTech Octopus requires the MCU be flashed to set the board into CANbridge mode, at which point that network is visible. I don't see any documentation or firmware to do the same for the Cheetah. I need some guidance on setting that up.
Coil noise
I hear very annoying and weird high pitch noise while the board is not under load (while printer is idle). Is there any way to suppress it?
Configs do not accommodate for extra 1k ohm resistor on thermistor
You need to include inline_resistor: 1000 on all of the thermistors on your config. You have it in the schematic but not in the config.
The thermistor will read incorrectly unless this is fixed.
No usb device found after flashing klipper firmware
After flashing klipper firmware the device is unable to apear in /dev/serial/by-id/
