There was a lot of discussion about alternatives for 4 axis, take a look at this topic:

Alternative to Fusion for CNC and CAM

Does FreeCAD fit the bill for you? It’s free, Open Source, multi platform, supported and does parametric modelling. Fourth axis is available: https://forum.freecadweb.org/viewtopic.php?t=36773 It also does output processing, which is what I’m investigating for use with SnapMaker.
