I’ve just fitted an SKR Mini MZ v1.0 control boards in my AnyCubic Mega Zero, it is able to print successfully from SD but I cannot connect connect to it by USB, I tried initially with a Raspberry Pi running Octoprint & then using a Windows 10 laptop, in both instances they didn’t detect anything connected. The laptop did not attempt to install drivers, nothing is showing in device manager. I’ve tried rebooting the printer, laptop and Raspberry Pi, different cables etc.
Can anyone suggest anything? my impression is that it’s probably a hardware fault requiring replacement but I don’t want to go through the hassel of swapping it out & returning it just to have the same issue again.
