This is the header/footer Gcode that I was able to get working.  It does look a bit different than yours, but I'm not sure how different the 2.0 is compared to my 1.0.  You can try this Gcode template and see how it works.

Header Gcode:
; filename = composition.3w
; machine = daVinciF10
; material = abs
; extruder = 1
M140 S90 ; Bed (no wait)
M106 S210 ; Start fan
G90 ; set absolute coordinates
G28 ; home all axis
M190 S90 ; Bed (wait)
M104 S210 ; Extruder (no wait)
M109 S210 ; Extruder (wait)
M117 Start
M117 Cleaning
M100 ; Cleaning
M117 Printing

Footer Gcode:
M117 Done
G92 E0 ; reset extrusion distance
G1 E-3 F600 ; Retract
M104 S0 ; turn off extruder
M140 S0 ; turn off Bed
G90 ; Absolute
G28 X-33 Y-12 ; home x & y
G1 Z100 ; Lower bed
M117 Down Bed
