I want to tell QGIS where to start with a marker, like: use 3 markers, start at positions 0, 2, 4, and apply an interval of 12 to each marker.
However, after searching for hours, I haven't found a way to deal with this issue.
Regardings Nathan's answer:
This happens if x-offset for markers is used:
Use Geometry Generator for label placement with Offset from point and use this expression (see below for variants A)if the solution should fit different map scales and B) if the labels itself should also be rotated):
project (
make_point ($x,$y),
2500, -- change the distance to fit your needs
-radians(180 - "rotation") -- rotation is the name of the attribute containing rotation values
)
The red dot indicates the actual point geometry; the value of 2500 in the above expression is the distance from this point:
If you zoom in and out, a fixed distance is not ideal as the label moves too far away from or comes too close to the arrow. To fit different scales, use a small distance value and multiply it with the variable @map_scale:
project (
make_point ($x,$y),
0.016 * @map_scale,
-radians(180-rotation)
)
If you want to rotate the labels as well, go down to Data defined and set a data driven override for Rotation, where you just set the attribute that contains the rotation angle (the same you used for the arrows).

You sure can.
First you need to add a Marker symbol to your line symbol and stack the symbols like so:
Click on the Marker Line symbol layer and set the with interval value to what ever looks good
