Simplify3D setup for a Printrbot Metal Plus

I cannot for the life of me figure out how to program the nozzle to end up a "paper's thickness" away from the printbed when the print is starting.

Hardware:

Printrbot Metals Plus
Glass print bed
E3D Hotend
Capacitive Z Probe PNP
Firmware: Reprap (Marlin/Repetier/Sprinter)

I just don't know what settings to program. I have tried the following:
--adjusting the sensitivity of my probe
--adjusting the probe elevation relative to the nozzle
--a script with G1 Z-(a value)
--a script with the M206 command
--Z-Axis Origin offset on the FFF Setting's G-Code tab
--Global G-Code Offset on the FFF Setting's G-Code tab
--Changing the homing direction between min, max, center

I think that is it. I have experimented with many combinations of these and always kept at least a few control variables but never had any success.
My starting script is the following:

G28 X Y;
G1 Y100 F3000;
G1 X100 F3000;
G1 E10; Prime
G4 P3000; Time to clean off the extruder tip
G28 Z;
G1 Z-5;
G4 P8000; 8 seconds during this troubleshooting

The G28 Z will position the probe roughly 5mm away from the printbed, which is why I have the "G1 Z-5". It doesn't perform the "G1 Z-5" command, then when it starts printing it will raise up to about 15mm off the print bed.

Any help is much appreciated. Happy Turkey Day !

Re: Simplify3D setup for a Printrbot Metal Plus

If you have a probe, shouldn't you be using G29 auto-leveling?

Re: Simplify3D setup for a Printrbot Metal Plus

I have tried the G29 and no difference.

Right after my last command the Z-axis raises about 4mm and the print starts. I have no idea where this 4mm comes from.

Below is my FFF file. I have no offsets set on this one because I have tried each on and nothing keeps the nozzle at the elevation that my scripted G30 command does; it always raises up about 4mm.

Offsetting the Z-axis origin, changing min/center/max, Global G-Code offsets, origin offsets, NOTHING WORKS !

Re: Simplify3D setup for a Printrbot Metal Plus

Open up your gcode file in a text editor and just use Ctrl-F to look for and "Z" commands. You can also search for "; layer" since that will get you to the start of each layer. That way you can see exactly what Z-values are in the gcode. If those look normal (for example, starting at 0.1 or 0.2mm and not 4.0mm), then you know the problem has to due with the firmware calibration. Most likely the probe offset or something like that. But this is an easy test to rule out any issues with the instructions S3D creates.
