Thanks for getting back to me so fast hood. I got it to work I changed the z to pins 8-9 and it works. this is all new to me. I bought the steppers (nema 23 287oz) BOB is ( DB25-1205) drivers are (DQ542ma). was not getting a signal from 2-3 just thought I would try and it worked. thanks I am sure I will have further questions.
