I upgraded my Sidewinder X1 MB to BTT SKR1.4 Turbo and can no longer connect my Octopi to the printer

What is the problem?

After upgrading my mboard on my Artillery Sidewinder X1 to BTT SKR 1.4 turbo, all is working great but I can't connect to my printer.

What did you already try to solve it?

I reinstalled Octopi on a fresh sd card to try a virgin install. I tried another cable, although the old one worked fine between the pi and the old mboard. Terminal shows various attempts to connect. N0 M110 N0*125 Handshake attempt #3 with timeout 2.0s.

Have you tried running in safe mode?

Yes, before I tried a new install

Did running in safe mode solve the problem?

No

You may try manually with other baud rates.

You may also try other USB cables.
