@l3ds I realise this is not the firmst Duet you have used so I agree its unlikely to be a configuration issue however it may be fixable by a firmware reload. This is why we want to see what happens when you connect to it over USB and then attempt to connect using a terminal like YAT.

Thanks for sharing! It's common to need to take EMC precautions with stepper motor cables when the machine as a whole is not shielded.

On the Duet 3 MB6HC, EXP3HC and Duet 3 Mini we added additional components on the board to reduce EMI from stepper cables, so in some cases no additional precautions will be required.
