CuraEngine detects if your start gcode sets the temperatures. If it doesn't, it adds them before the start gcode in the final gcode file. That way it ensures the hotend and heated bed are at temperature before trying to prime and print.

Make sure you include

M190 S{material_bed_temperature}

and

M104 S{material_print_temperature}

in your start gcode (after the M80 line) and CuraEngine will not put them in the gcode before the start gcode. Note that CuraEngine actually looks for the {material_print_temperature} part, so if you have absolute values (eg M190 S200) it will still add those lines by itself before the start g-code.

Thanks, I'm running dual extruders and I want both extruders set to nozzle wiping temperatures (160C for PLA), not print temperatures, because I wipe the nozzles right before I run the auto bed leveling code.

It would be nice for Cura to have a checkbox to run Startcode before everything.

As is stands now, I have to go into the gcode and delete the nozzle printing temperatures that Cura sets (200) and use my startcode to set the nozzle wiping temps (160C) and the printing (200C ext0) / keep warm (150C ext1) temps.
