> As for baud rate, this is a setting specific to this ender board. I ran into this problem when I set up klipper initially and changing it from 250000 to 115200 fixed the issue entirely. For sake of argument, I just tried it at 250000 again and returned the same result.

@huhen uses #baud: 500000 and the same printerboard.  
I would give it a try…
