Slicing recommendations
The current version of Cura supports relative extrusion under the "Special Modes" section.
For best accuracy we recommend slicing with relative extruder coordinates. This avoids the accumulation of rounding errors that firmwares suffer from when using absolute extruder coordinates. All popular slicers support relative extruder coordinates.
In your slicer start gcode, include command M82 if you are using absolute extrusion, or M83 if you are using relative extrusion. Some slicers insert these commands automatically, others do not.
RepRapFirmware supports multiple tools (i.e. print heads). You must always define which tool you want to use at the start of a print. If you are slicing for a single-tool machine, include T0 followed by M116 in your slicer start gcode.

Cura now supports Relative extrusion via a checkbox in the settings menu. Might be under experiential (They moved it once).
It works perfectly fine, even without M83 in the startup Gcode. Need M83 in config.g though. Of course.

Cura 3.3.1 has it in the “Special Modes“ tab

What about Simplify 3D slicer software

I know this is a late response but for others. For Simplify3d slicer, Settings>G-Code (tab) > G -Code options> Relative extrusion distances
