Ok, the change suggested above (thanks JoeJ) for handling the Build Platform worked great. Extending the logic of this change I added "M135 T1" to "Advanced", "Scripts" "Tool Change G-Code". I can now change the temperature of the extruder as well. Note that I am using only the left extruder in this scenario. My machine is loaded with ABS on the left and PLA on the right. Am not sure what the solution is for doing a dual material print but I am not there yet anyway.
