Print from SDcard on boot

Is it possible to print from the SD card on boot using these boards? For example, once connecting a 12V power supply, the board should power on, and the firmware should read a file from the SD card and begin printing that.

Normally, marlin firmware uses a file called autostart.g from the SD card and prints from that on boot. But when I include that file in the root of my SDcard, the SGEN_L doesn't start printing from it when power is supplied.

Is the SD card only used for firmware flashing?

Is there any way to print from this board without using a USB connection?

  1. It is very certain to tell you that SD is supported for automatic printing;
    2.gocde file name must be auto0.g instead of autostart.g
  2. You re-edit the gcode file name to try, good luck!

Thanks. In my own custom firmware, I did not have #define SDSUPPORT. But this firmware does have sd support enabled by default. I thought it was a problem with the board.
