Browsing a different forum I came across a link that gives information that may be useful to people who are using a dual extruder and Slic3r regarding the custom start g-code:
"
Note the use of the “[first_layer_temperature_0]” variable. I couldn’t find this documented or addressed anywhere, but I tried something and got lucky. The variable seen in all the documentation and the Slic3r .ini files is “[first_layer_temperature]”, but on my dual extruder printer, that was returning two numbers separated by a comma. So the resulting g-code would be M104 S225, 225 T0 (which doesn’t compute). On a whim, I decided to try “[first_layer_temperature_0]” and found that yes, this will return just the value for the first extruder (and “[first_layer_temperature_1]” is for the second extruder).

Link was about a different printer, but the above info is relevant for us. Link is [
