[BUG] octoprint keeps loosing serial connection to new experimental build

[otkaz]

Did you test with a precompiled firmware?

Yes, and the problem still exists.

Bug Description

I just upgraded to the new experimental build from 20240122 on my stock ender3s1 f4. Used this file
https://github.com/mriscoc/Ender3V2S1/releases/download/20250106/Experimental-Ender3S1-F4-UBL-20250106.bin
I have it connected to octopi and I keep getting comm issues and have to reconnect after about 5 mins or so. I tried switching the 115k baud but the issue persists. Switched back to the old build and issue went away. I didn't see anything in the octoprint logs except for a comm error that it lost connection.

I'm still having this issue any time I try the experimental firmware with octoprint. Is anyone else running into this or is it a problem with just my setup? I don't have this issue on the sable build.

No response from printer after 3 consecutive communication timeouts, considering it dead. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves.
