First of all, it is not advisable to use a laptop to control Mach3. Mach3 takes over the printer port and needs full control. Laptops have power saving features that interfere with this. You may find this out later, but for now, it'll do to get you up and running.

Have a look at this ftp://ftp.machsupport.com/Docs/Mach3...20Tutorial.pdf It is worth going thru the steps to get your steppers stepping. Do you know what pins your machine uses - useful info to have this written down.

Cheers,

Rob

PS I have never figured out what those green thingies mean on the diagnostics screen.
