Hi Marwellca,
I have seen others use laptops without any problem but in my case all sorts of troubles were caused when I tried using a Dell Inspiron laptop. I tried an old PC and it all was cured. So, I think you will have to try it for yourself and see the results (obviously the make of laptop has something to do with it also the type of power supply used for the CNC).
