Modbus RTU Communication Help

Don’t think, that is possible. Sorry.

RS485 for low-speed peripherals (reusing existing AMS feeders)

It’s technically possible, but it would require some coding work. The main issue I can think of is that the Klipper mcu is expecting to be able to transmit messages to the host at any time (and the host is also expecting it can send messages to the mcu at any time). So, some form of “line arbitration” is needed to handle cases where more than one chip wants to send data at the same time. The usb and canbus protocols handle this at the hardware level, but as far as I know, there is no standar…
