flashcut cnc problem/question

Hello all,

I have just started using flashcut CNC and its interface box with by
dell latitude cpx p3 750 running w2000. The software seems to be
losing communications with the signal generator box intermitently
during a cut. Anyone had this problem or have suggestions? I am not
sure I will keep this unless it has a real fix and it reliable, kind
of expensive to be a nuisance.

I am using geck 201's running 180 oz vexta motors on a sherline 5400
mill.

Thanks for the help.

John
