Simplify3D Print Bed Calibration Issues

Hello,
I just bought the Simplify3D after seeing so many people rave about it. However after downloading the latest version and selected Robo3D R1+ profile, the first print ended in disaster. It did it's calibration and stuff, however it was printing way to high, like 2mm high and you can see the filament just drops to the bed.

I did copy the script from MC to S3D, but now it seems to heat my extruder and then it rests my extruder back to 0C without printing. Can anyone help me decode my issues?

S3D default script (Extrude the filament way too high):
G28 ; home all axes
G29 ; probe the bed
G1 Z5 F5000 ; lift nozzle
M109 S[extruder0_temperature] ; set the extruder temp and wait
G28 X0 Y0 ; home again to start wipe
G1 X20 Z0 F4800 ; wipe

MC default script on S3D (Will heat up to printing temp, but printer rest itself back to 0)
G28 X0 Y0 Z0 ; home all axes
G1 Z5 F5000 ; lift nozzle
M109 S[temperature] ; set the extruder temp and wait
G28 X0 Y0 Z0 ; Home Z again in case there was filament on nozzle
G29 ; probe the bed

Re: Simplify3D Print Bed Calibration Issues

Many times each software program will have a separate Z offset that determines the position of all other coordinates in the gcode file. So the auto-leveling just makes sure things are level, but the Z offset in the slicer basically moves the print up or down to either squish it into the bed more, or move it further away. So even if you have the same starting script, you may still need to configure that offset.

The steps for changing the offset are explained here (see the "Nozzle starts too far away from bed" section):
