I believe you just specify the T parameter for the M104/M109 command, T0 being extruder nr1 and T1 being extruder nr2...
M104 S200 T0 ; set 1st extruder temp to 200, don't wait for preheat
M109 S200 T1 ; set 2nd extruder temp to 200 deg, wait wait for preheating
But you may need to send tool change first with M6, or change gcode to address extruder via A/B axis. I am not sure which one Ultimaker / Marlin supports.
M6 T1 ; change to 2nd extruder
G1 E10 ; extrude 10mm from 2nd extruder
M6 T0 ; change to 1st extruder
G1 E10 ; extrude 10mm from 1st extruder
- or -
G1 A10 ; extrude 10mm from 1st extruder
G1 B10 ; extrude 10mm from 2nd extruder
I don't know which is correct, it shouldn't hurt anything to test via console, but I can't be responsible if you break your Ultimaker.
Either way you would likely need slicer support for dual extrusion, or handroll your gcode. I believe the development version of Cura has some support coming for this, hopefully Daid can provide some more info.
Cura already has dual-extrusion support for 2 versions now.
The "G1 A10" won't work, only the E and switching with T are implemented. Which is a bit of a shame, as the A/B method could control extruders at the same time.
