Simplify3D won't heat up head before printing

hey guys, totally new to the printing scene but so far loving it, bought a "anycubic" Kossel and yeah it's pretty wicked at the minute, using a few programs and stuff to get the hang of it and which one I like etc. I have been trying to get "simplify3d" working, all the settings look good but when I start to print then after the bed heats up instead of it heating the print head up it just lowers down and starts to print...

I've double checked everything that I can see?

Any ideas??

Thanks
