The pin from parallel port depends on your TYPE of BOB and where you pick up the connection

You still need to tell us which 'Break-out Board (BOB)' you are using WITH your stepper drivers (UIM240). You need a BOB to send the signals to the drives (UIM240).

window_s,
Break-out Board = 25 pin Interface board.
What type of board did you use?

This will be a difficult one :o

KenC	Sun 31 July 2011 23:50

Actually, IMHO, any 25pin parallel port BOB will do... You can even run without one...
I recon Window_s has a language problem more then anything else. Give him/her some time...
