Re: SD card doesn't work

Hi im tryin to use SD ramps, im enabled it in marlin. the software pronterface can pick up the sd card and read the file. when i click on the file it loads the file and starts printing. however when i press the disconnect or pull out the cable from the pc it stops printing. the led is on on the arduino when i plug out the usb and the D1 and D2 is installed on the ramps.

Does anyone know where im going wrong.
Im naming the files test.gco this is ok isnt it?
thanks
