Extruder not working-Ender 3

[bfpa40]

I have an Ender 3 with the original Extruder motor. I am using a DUET 2 Maestro with RepRap Firmware. On my Panel Due 5i i go to Extruder>Extrude>5mm or Retract>5mm and the motor doesnt move at all, there are no sounds from it. The GCode Console reflects the following:

7:47:24 PM: : Error: Attempting to extrude with no tool selected.

Where should I look for problems, or where do I "Select the Tool" for the Extruder. I have the Extruder cabled in to E0 on the Maestro. Is there somewhere or some setting in one of the system files that might possibly need to be tweaked?

Try adding 'T0' to the end of your config.g

Or on the panel due touch the little button above the tool temp to select that tool.

I got it working..I DID NOT have my hot end up to temp. All is good!
