Driver wiring help...

[mike]

Hi
i have upgraded my drivers to Zapps 752 5.2A drivers in the control box (Gary has been amazing & the service is FAST) as with anything i do i do every thing over the top instead of gradually do things bit by bit i find myself getting ahead of myself but i am currently stuck with the new drivers as i dint under stand where the -5v signals i know from the diagram on page 7 http://www.slidesandballscrews.com/p...uals/PM752.pdf

the pulse+ & dir + take the 5v+ but i don't know where the 5v- goes to, i am currently using a routout cnc break out board http://www.routoutcnc.com/25WayD.pdf from my old system i was told it goes to this but this doesn't
make sense i was hoping there was someone on this forum could point me in the right direction
thanks guys
