I have an A30T Smartto_MB_V1.0 Control Board in my 3D printer with a Smartto_LCD 3.2" Ver2.1
touch screen monitor. When I upgraded the firmware A30_APP_M_V1.39.62.bin and the A30_APP_S_V1.39.62.bin to the
installed the board and restarted the printer, the touchscreen monitor suddenly stopped working.
What could be the mistake? Have x different bin. Files are played on it, nothing works anymore.
