From Object menu, choose Objects to Marker.
Draw a path.
Select path, from effects menu, choose Modify Path - Add Nodes,
choose Division method: By max. segment length.
Choose distance between nodes (where your markers will appear). Apply. Close the Add Nodes window.
With path selected, choose Fill and Stroke menu (ctrl-shift-f).
Choose no fill (unless you want it).
Choose stroke transparent (a=0).
Choose Stroke Style - Marker and choose the marker you defined before. The width parameter in unit px will be a multiplier for the size you gave the circle before.
You can adjust the distance between markers/nodes individually, if you need to.
