@jay_s_uk what are my options? Keeping mounting holes the same would be ideal. Any performance difference to be expected from upgrading DuetWifi to duet3?

@jay_s_uk yes, ordered from Duet in 2018. No issues until yesterday.

@jay_s_uk yes, I’ve tried many micro usb cables. Nothing appears to be hot on the board. Would disconnecting all components rule out a short in cabling?

@jay_s_uk any ideas what could have caused it? Looks like board failed mid print with many successful prints prior to that. It’s connected to power surge protector too.

@Phaedrux thanks for the suggestion but I’ve already worked through that guide getting to the end where all methods failed. Hoping for any other ideas before board declared dead

@T3P3Tony I've tried that. Board not recognized and red diag led solid. Thank you for suggestion

Earlier today printer stopped mid print and since, I have been unable to connect to the board using bossa. Red diagnostic LED lit at all times. Board not recognized once plugged in via usb under device manager. Tried MacOS as well with same result. Is the board dead? What could have happened?
