@bearer Thanks for your reply! I saw it after the post and sent a message to duet. They got back to me within two hours and said they are working on quality checking the rest of the 6HC boards before shipping out replacements.

I recently got a Duet 6HC Mainboard. It connects fine through the web interface, but the motor drivers report error: short to ground every time I try to write to them. The serial number starts with WD41.

Cheers, Noah
