I tried to do a 2 color print, a pause and spool swap, but I get the error message on screen:
// Unknown command:“M0”
and the printer just kept on printing. Does anyone have a work around? Command M600 doesn’t work either.

instead of m600 command just use pause, for me worked, when the printer was working. 😂

I did use pause. That’s command M0 in Marlin.

I mean literally use pause, not M0.
