what is the Gcode to run 2 extruder motors in the same time?

Is there any gcode to run 2 extruder-motors in the same time for Repetier firmware?

What I am trying to do is: sometime running both extruder-motors in the
same speed in the same time, sometime for extruding, sometime for
retraction.

That is not possible.

If you have a mixing extruder you can set weight ratio 50/50 and both will move the same - but then they should share the same heater. This is not really parallel but switching one step A one step B extruder.

Yes... it is single heater, good to know about the mixing extruder.

I just wonder what is the Gcode so I can send the command manually. Please let me know.

Mixing extruder only send E and depending on weights the move is split on several motors. See description for mixing extruder.

I am confused which description you are referring to. Please elaborate.

And can you show me a line of Gcode to command the mixing extruder please?
