Describe your issue:

For the life of my I can not get the mcu to be recognized. I’ve done the steps to fix the serial/by-id/* issue but that didn’t solve the problem. I’ve tried 4 different USB cables but that doesn’t seem to work. It worked once and i tried to home the machine and it jolted a little bit then stopped. changed the current on the steppers saved and restarted and it never came back up. Have tried the original printer.cfg i had before i modified the current values. I’m at a loss at the moment. Any help would be appreciated

What do you think what <your-mcu-id> means?
