on the gcode side of things.
comment out the lines you want to remove and see what happens.
to commen out - just put a ';' at the start of the line and s3d will ignore it.
This way you keep the gcode in case it's needed and just ignore the bits you want to check. :-)

so:
G1 X100 Y-68 F180 ; Wait for ooze
G1 X110 Y-68 F5000 ; Fast wipe
G1 Z1 F100 ; Lift

becomes:
; G1 X100 Y-68 F180 ; Wait for ooze
; G1 X110 Y-68 F5000 ; Fast wipe
; G1 Z1 F100 ; Lift
