Can I cancel the key function of SD grbl?

[viewsat]

Hello:
Can I cancel the key function of SD grbl? Or can you tell me where to modify the program.
Or it can be modified to read the grbl sd card period, if it exceeds the set time, it will end the read and return.

When I connect to grbl (arduino uno) without sd card, it will stay waiting and not work

In file SetupTxt.cpp, there is curently a line
fillMPage (_P_PRINT , 8 , _SD_GRBL , _JUST_PRESSED , fGoToPage , _P_SD_GRBL_WAIT) ;

You can comment it adding "//" in front of it so like
//fillMPage (_P_PRINT , 8 , _SD_GRBL , _JUST_PRESSED , fGoToPage , _P_SD_GRBL_WAIT) ;

The button will not be displayed anymore.

Thank you!
I used your instructions to modify, the SD grbl button has been cancelled.
