i found this topic, and downloaded the xml file attached their and in Diagonisitc Tab i got 5 pins Green .
i tried to figure the same pins and dir inside it, but the motor with no action ,
i tried to re-install Xp sp3 again , but no change ...
i use Dell Latitude E5400 laptop and bought " legacy Extender " to get parallel port and it worked before good with Mach3 with previous board .
i will try later with PC and see what the problem ,
it make me angry it works well with kcam till now ...
so it's not port problem ...
