AXBBE runnig perfect but lost connection once

[Cruiser1]

My AXBB-e ist running really good but once it lost ethernet connection to the PC?
Are there any settings in UCCNC like Buffer etc that should be changed ? Settings in win7 ?
Also working on the PC ( pressing buttons on UCCNC changing view or so ) makes the running program stutter. You can hear a interuption of the cutting sound.
This was one of the reasons not to use parallel port....
Thanks for some ideas.

Yes, there is the communication buffer length parameter in the settings.
Usually 50-100msec works fine on a computer with proper power (CPU/GPU/RAM etc.) to run the UCCNC.
