What is the problem?
My Ender 3 has been running fine for two years until last week and now this.
I get the message: State: Offline after error
No more candidates to test, and no working port/baudrate combination detected.
I also have the blue screen of death which I have added the firmware:
Ender-3 Pro_4.2.2_Firmware_Marlin2.0.1 - V1.0.1.bin
and still nothing. Its a mess!
What did you already try to solve it?
I have switched USB's per past similar instances and even change the power supply too.
Logs (syslog, dmesg, ... no logs, no support)
I hope this is the correct log, I'm novice when it comes to this stuff.
