i feel ppl are thinking "man this guy is demanding" hahaha.. sorry ppl just tryin to learn a new trend...

thanks all who have inputted.

hi thanks its a desktop pc now.. with onboard pp, i wasnt gonna use the lappy anyway.. but me being me had to play, and yes im just bench testing, (not even got motors yet) so testing what i can.. did a continuity test on the lead... mmmm trickery eh! well it came with the bob and 542 drivers. so who knows.. i think tomorrow ill test voltage through the lead would that help... how did you sort it...

yes the bob uses usb power...

so the 3.3v is converted by the bob.. to 5v is this right.

which terminal should i be getting my voltage change on the bob.. ie xs or xd...like i said xaxis is x-s and y is yd

think thats all

Ermm what bob is it.? you don't need 5v just a big enough difference between Hi and Low at 3.3v there's not a big enough differential and so unreliable signals.

Give me some details of what you have and I'll have a look.
