I've just dusted off a Suregrave Excalibur /cnc machine that has been languishing in the corner of a classroom for several years.
The controlling software it came with (EngraveLab, MiniCam, MillWizzard) is all out of date or out of licence.

What recommendations would you give for software, to use it to its best potential?

We have Techsoft 2D Design, which is adequate for basic engraving at different depths, but we'd like to use it for 3D milling if possible.

Any suggestions?
