Heatbed and hotend are not working/heating

Hello Smoothies,

I have setup my Smoothieboard with my 3D printer, and so far I have been able to jog my motors on all axes, as well as turn on/off my fan. I am using Simplify 3D as my host. When I try to bring my hotend or heatbed up to temperature they stay cool. I have them connected to the default mofsets. What am I doing wrong? Any help is appreciated. Thank you.

Can you describe how you have everything wired up ?
