|   CAK6140V CNC Lathe User: Hello CNCmakers, we have a CNC lathe machine from SMTCL, and the controller is GSK928TC-L, now the screen on the CNC system is too bright, we barely see the letters on it, how can we adjust the brightness? Thank you. 
 CNCmakers Support: The color screen is not supported to adjust brightness, it need to be repaired. |
