I’ve gotten a dual board setup working relatively well using a SAMD51 Thing Plus. I’ve run into an issue where the whole setup will hang-up after longer motion commands. The Thing Plus and both AutoDriver boards will need a hard reset in order to start working again. If I just reset the Thing Plus, I can communicate with it over USB until I send another motion command at which point the Thing Plus will hang up again.
Does the same behavior happen with just one board hooked up?
