I have an Ender 5 Pro and installed a replacement board v4.2.7. I found the correct firmware on the official Creality site and successfully installed the .bin file via SD Card. All boots normal and I have control of the bed and nozzle temperature. The problem is none of the motors will move. I checked voltage on each motor terminal as well as pins and they all read 22.8v+-. Also confirmed no loose connections.

Additional help or troubleshooting strategies would be appreciated.
