Would be very easy to add this. Because, for example, auto-home is:
So, adding:
MENU_ITEM(gcode, "Home X/Y", PSTR("G28 X0 Y0"));
Would add the command you want :-)


I still need to fix the "multiple GCode commands" option, as the cooldown option:
MENU_ITEM(gcode, MSG_COOLDOWN, PSTR("M104 S0\nM140 S0"));
Only cools down the hotend, and not the heated bed. So the M140 S0 doesn't get executed.

 Endstop Testing


No matter which type of endstop you use, it should be recognized by your electronics. Test procedure:


    Turn on your electronics/printer.
    Send M119 manually.
    Firmware should report back status "0" or "open".
    Engage the endstop by pressing the switch, putting cardboard into the light barrier, etc.
    Send M119 again.
    Firmware should report "1" or "triggered" or "closed".


Your endstop works if both reports are as expected.
