Feature Request: Send G-code (scripts) to printer like in the terminal

[Quas7]

Hi,

to adjust Z-distance during printing of the first layer remotly, I would like to be able to send M290 and G92 to the terminal (Z-babystepping).

http://marlinfw.org/docs/gcode/M290.html https://forum.duet3d.com/topic/209/babystepping-by-g-code-macro/10

see also my second "zoom in video" request for this purpose.

Best, Quas7
