I dont know if the problem with the “blob” is solved but I post anyway.
Simplify3D is exelent software for me. But I had the same “blob” with my Wanhao 4 when I did my first print. It was Simplify3D that had those actions in the start-gcode. It is a feature that you can write your own g-code for specific actions, like the start off a print.
In Simplify3D:
When you add/edit your active process(your settings for the print) You klick the Scripts-tab
There you have tabs for g-code for the actions Starting, Layer change, Tool change and Ending
The Starting G-code will be added in the machine-program before the code generated by Simplify3D(the movements you see in the simulation after klicking “prepare to print”
The code there is for heating the nozzle and the buildplate and also for extruding a bit filament so the nozzle is ready and primed when it starts printing
You can add whatever code you like there to get the machine to do what you want in the start
If you can not make your own starting code, you can take mine if you want. I dont leave any garantuee on that it will work, it is makerware-code that I have changed a bit so the nozzle is wiping against the glass a bit in the end.

Copy it and replace the code under your “Staritng G-goce” tab, but backup the original code first if something goes wrong
