SDHC card not readable?

Is there a secret to getting the LCD controller to display the files stored on a SDHC card? I have 2 new sd cards one formatted FAT32 and one not formatted with a xxx.nc file on them and both will indicate being inserted but will not list the files in the menu. I can manually move the axes via the controller.
I’m using all vicious equipment and have flashed with this file.
rc7_mpcnc_lcd_9916

Rename it to .gcode. I don’t think the LCD sees .nc.

Mine has to be .gco or .nco on a FAT32 card. not sure if theres a size limit to the card. Mine are 2gig. (recycled old camera cards)

Thanks Bryan.

Did that work for you to make it .gco vs .Gcode? Im trying to resolve this same issue with mine!
