I made a simple spline in creo and exported it as a dxf using these settings:

I then imported it to robodk using dxf2gcode but for some reason small circles appears along the spline:

This does not happen if I make a simple circle:

Does anybody know what causes these small circle and how to avoid it?

Can you provide the DXF file?

The issue was happening because I had set the machine type to "draft knife". Setting it to "milling" and the circles were gone.
