As a total beginner to mill cnc conversion I have been doing a lot of research and whilst looking at the Mach 3 web page, http://www.machsupport.com/

I was a bit surprised to read the following under the "Mach 3 minimum requirements" heading:

"Laptops are not supported because the power saving features of the chipsets disrupt the pulse stream"

I was hoping to use a laptop with mach 3, is this possible?

I'm also looking at the Vectric software packages http://www.vectric.com/ as I'm interested in engraving,sign writing and photo machining. Does anyone use them and can you tell me if they are any good?
