What Free Software, Open Source Software or at least <150eur commercial software exists that does real 4 or 5 axis toolpathes?
Meaning actually moving more then 3 axis at the same time,
Not just doing a 3 axis milling with one axis being rotational.


(and usually not even caring about the specifics of rotational axis such as
0=360,
speeds near the center being different to speeds far from the center and machine control programs being too dump to care
and path distances near the center being different from path distances farther out)
