Carbide Create doesn’t have a feature for this.
It might work to use the new Circular Array feature:
to rotate a single letter around the circle six times, then manually edit each to be the correct letter — it will be uniform spacing, but the alternative would be to either drag and rotate each letter individually or to export to an SVG, then re-set the text and use a 3rd party tool such as Inkscape:

you’d then need to convert the text to geometry using Path | Object to Path.
