i’m eager to learn how to play a file from sd card by pressing only on button without any software,HMI or PC-connetion.
by the way i don’t want to play a file as “on_boot_gcode”.
so here is the deal. i put a gcode file with a specific name in the sd card and define some input control keys to play a file without HMI or PC.
is there any way to reach this purpose?
