Dsp control vs mach3 software help

[Rya]

Hello, I'm trying to understand the difference between dsp based control systems and mach 3 based motion *control boards. ( this being for laser engravers marketed online). *Most of the Chinese laser engravers provide dsp control but this does not say a lot, and i,m not sure if it is compatable to the mach3 software. I,m familiar with the Mach 3 software but need an explanation regarding Mach based control hardware and other 'dsp,' control boards.

Please advise,

Regards.
