If your print head is 5 mm above the bed that is really too high depending on the machine setup.

The "zero" spot for the z axis should be about a paper width thickness from the bed. I am not familiar with that machine, but all the ones I work with start with 0 right by the bed.

Check in slic3r is pretty basic in these setting, so there should not be much initial "preprocessing" movements.

In pronterface go to your slicing settings under the settings menu.

on the start / end gcode what are you seeing in the start section?

Is it just a G28 (home all axis) command?

Thanks!
