How to print from the left extruder only

Greetings!

New to all of this and after doing a search of many FlashForge, MakerBot, and 3D forums I have not located an answer. I have a new FF Creator Pro and am using MakerBot to print from. I would like to be able to choose to print from just the left extruder if possible. I have two different colors loaded in the printer and it would be convenient if I could choose which color for the print. I have "clicked" on everything I can think of in MB and it might just be my ignorance but can not see anything that would seem to designate one extruder over the other. I have ReplicatorG but can not get it to connect to my printer.

Any help is greatly appreciated!

Select the model and click on the "i" on the bottom left. It should come up and say which extruder, left or right. In device you will need to have Replicator (Dual) selected. In settings set the right extruder to 0c.

If you have the device type of Replicator (Single) you wont get the option to switch extruders since the right is default.

Thanks! I really appreciate the help.
