Dual Extrusion

So ive been used to using Cura that has dual extrusion down pat however I loaded my Jg maker into Prusa and have been trying to set up dual extrusion and it feels like its impossible.

Im trying to change the extruder that prints the purge line and nothing I change will change it to E2. I've put int the T1 command and get nothing. There is no way to change the default extruder either, like cura. When I change the Extruders to 2 under multiple extruder tab it does nothing.

What do I need to change in the start code in order to get extruder 2 to purge line and not e1?

Try switching the order of the parts in the print tree - right hand pane - and as long as it fits the internal logic the printing order will change.
