No printer attached. Marlin not working. No idea how this started. I’ve read around a lot and tried multiple firmware updates; I even took the bottom panel off to see if anything internally was loose. Any idea what to do?

For skr 2 you need to look at the numbers on the chip. There is a STM32f407 and STM32F429. These are the current official BIQU B1 firmware. https://github.com/bigtreetech/BIQU-B1/tree/master/Firmware/2022-03-27 select the one that matches the chip number. I recommend doing the screen too. Look at the screen chip too since there is a chance of it being a GD version instead of the STM. The chip shortage problem has made it so they need to use equivalent alternatives so it's important to choose the correct firmware.
