I am a newbie and enjoying Mach3 so far, I am wanting to import black and white image designs  of work ive designed in Ai and basically looking for the best software to cut the required shapes out of MDF any suggestions on the best software for this please?

Check out the Vectric range of software (Cut2D perhaps ?) https://release.vectric.com/

Tweakie.

Vectric for sure
