Any ideas what could be causing this ? ( image attached )
Graphic LCD on Ramps & Mega 2560 with Marlin.
The SD card that is part of the LCD unit is still working as the print is still running.
Happens every few weeks. Sometimes hours in to a print, sometimes within minutes. No set pattern for timing.
Have changed cable from LCD to Ramps to metal shielded cable.
Is there a Marlin routine or function that I can call with a button press to a specific pin number that will reinitialize the LCD display, without affecting the SD card operation ?
