I've just replaced the motherboard in my 3D printer (Anycubic Mega Zero v1) with a BigTreeTech SKR Mini MZ board, mainly to add a heated bed. In every other respect it seems to work perfectly but I can't connect to it by USB. I tried first with Octoprint which seems to have known issues (which I suspect would have been resolved with an upgrade to custom firmware) but worryingly I can't connect from my laptop either. It's not attempting to recognise the device, install drivers, etc & no unknown devices show in device manager.
My thinking is that it's a hardware fault (everything's gone wrong on this build) but I'd love to be wrong and get it working rather than have to do another swap out. Any ideas anyone?
