This place to start might be the software workflow and the graphic in the first post of this topic.
If you have a DXF that you want to use (unaltered), you are looking for a CAM solution. CAM solutions will import a DXF directly. The most popular CAM solutions used by members of this forum are Estlcam, and, as a distant second, Fusion 360, and there are a few others in use. The one gotcha in importing DXF files into CAM software is that they don’t contain the unit measurements used when the file was authored. When importing the file, you need to specify if the units are millimeters or inches or feet.
Fusion 360 seems like a good program but I wonder if paying that license is worth it for what I’m about to do.
There is a free (personal version) of Fusion 360. You may have to dig a bit to find it, and there are a few limits on that version. It is the version I use. Note that the Fusion 360 (Imo) is a more capable CAM solution, but has a substantially higher learning curve.
