Nothing happened except for ok, right?

bobc commented 7 years ago

Are you sure that is an invalid command ? With Marlins' G code spec, it is interpreted as

G1 D{d} D{d} R{r} E{e}

where {x} is current value of parameter x. This is effectively G1 to current position (the other parameters have no effect).

Edit: oops

That's valid G-code.

Marlin doesn't return an error for unrecognized G-codes. They are all treated as no-op.
