Good morning all. Have a problem that someone may be able to solve. I'm running a very long rastering program with a Taig mill and Mach3. My computer is connected to Comcast High Speed Internet. When running the Mach3 program on the mill all other programs are closed. Only Mach3 is running. After about an hour or so, X-axis stops as though it ran out of travel. I have to restart the program near where it stopped using "run from here" feature. All runs well again. Question is, should I unplug internet cable when running Mach3? I'm wondering if McAfee (my security suite) is interfering or should I look elsewhere? I have another processor I plan to dedicate to Mach3 exclusively, but as yet haven't hooked it up yet. Any thoughts? Thank you very much.
