EZ-CAM looks great but way out of budget. Spent $60 for Estlcam, https://www.estlcam.de/. That was after a bit of a search through a list of software (but not all). It is an Alibre Drawing to DXF export like most, but gets what I need done for now.
Tried Dolphin CAD CAM and it makes you load its entire suite of software, and cannot import splines from the DXF (wasted $49.00 on Mill Basic).
