Marlin end code - relative distance

[dustmann]

Which slicing software are you using? slic3r sets a G90 command at the beginning of a print to use absolute coordinates. Your G91 command set at the end of the G-code can remedy this as you have noted.

edit:

I have noticed that after completing a print and homing X/Y, it appears that when a new print begins without resetting the printer, the motors try to home even further (from the home position) resulting in a lot of skipped steps or mechanical crashes. Therefore as Mjolinor mentions below this is definitely not the recommended solution.
