What is the problem?
I upgraded the mainboard in my E3P to a Creality 4.2.7 silent board 32 bit. My Octopi does not connect to my printer now.
My terminal in Octoprint states:
Changing monitoring state from "Offline" to "Detecting serial connection"
Performing autodetection with 0 port/baudrate candidates:
Changing monitoring state from "Detecting serial connection" to "Error: No more candidates to test, and no working port/baudrate combination detected."
Changing monitoring state from "Error: No more candidates to test, and no working port/baudrate combination detected." to "Offline (Error: No more candidates to test, and no working port/baudrate combination detected.)"
What did you already try to solve it?
I have reflashed the firmware with Marlin 2.0.X.
I have tried setting the Baud rate to 115200.
I have reset my Octopi.
I have tried different USB cables.
I have covered the 5V pin on the USB connector.
Have you tried running in safe mode and if so did it solve the issue?
Yes and no it did not resolve the problem.
