You're ok for reprap flavor.

And as expected, these lines are causing the speeds to be slow.

Delete them from your start gcode.

I removed the starting gcode info and the print was much faster.
Thanks for that!

Regarding the probe calibration.
I had run that previously.
But, I ran it again anyway.
Even after running it again, I had to babystep +0.6mm to get filament to flow.

Is there someway to make the baby steps permanent?
I have to adjust for every print.

If you constantly need to baby step up 0.6mm then you can simply modify your G31 Z value to take that into account. That's how you make it permanent.

It could also be that you are homing Z at a different location than where you are measuring the offset. Ideally they should be the same location at the center of the bed.

I have the config.g file G31 Z value set, but I still have to adjust each print.

I'm still printing the test "DUET" text. Same gcode, just rerunning it.

I understand, but if you're consistently needing to babystep, then you can modify your measured G31 Z with that baby stepping amount to make it permanent. Consider it a fine tuning of your G31 Z offset.

If you have G31 Z2 and you have to add +0.6mm to get a good first layer because your nozzle is too close after homing with the probe you can take 2mm - 0.6mm = 1.4mm and change to G31 Z1.4

@phaedrux

That seems to have done the trick.
Thanks again.

One more thing I'm having trouble finding info on.
When the print is done, the X/Y carriage moves.
In my case towards the front of the printer.
I would like to move it towards the back of the printer.

That would all be controlled by your slicer end gcode.
