Dear @bydripz Ender 5 plus, Z-axis drive voltage is 0.82-0.85, we suggest you test the electric board directly.

@kybelvody The printer only recognizes sd cards with a memory of less than 16g, and only recognizes gcode files. The file name is within 16 characters, and the file name consists of letters or numbers. It is recommended that the SD card only stores the models that need to be printed. 2, Please download the firmware on our website and update: https://www.creality.com/download
