I am running Mach4 connected via USB to my CNC machine which has a WiXhc USB Motion Card interface. I am getting an annoying buffer full error at times which I do not know the reason for, apart from the obvious meaning of "Buffer Full". Can anyone enlighten me as to what the error "USB Buffer Full Error" means and what generates it? What buffer is it referring to and what do I have to configure to stop the error occurring. I have read a lot of posts referring to this type of error but nothing that is very specific.

Thanks in advance for your help. Jim.

Why USB? Ethernet very easy to use ,no any problem and best it's add PCI Ethernet card this will close all cominication problem
