When you say "pin (04)" do you mean parallel port pin 4 or BoB pin 4? BoB Pin 4 is a limit input, connected to parport pin 13, and is an input not an output. Parallel port pin 4 is connected to the STEPY output, and I suspect you need that for moving your Y axis? (If not, then it probably should work) It looks like the relay board probably needs a 5V supply in addition to the logic and gnd connections. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
