    So, here we go, machine almost assembled, wiring done, now need to connect all properly to the ramps…

    As I do not want to blow it all at first attempt, here is the wiring according to my understanding, please tell me if I am right (or wrong!).

    For my steppers, the pairs Black/Green and Red/Blue are the ones with the biggest resistance.

    Looks good to me, I use RAMPs as well  (but added a Z probe) – remember to apply small steps (1mm) to test proper stepper direction (if you already attached the belts).

    Finalized assembly….Apart of noise, the steppers are going nowhere…
    My setup : dual end stop, mega2560-ramps-drv8825-1/32steps-LCD screen
    I doubled checked my wiring, when trying to move using 1mm steps from the controller, steppers just make noise but don’t move at all…
    Now, i have doubt about the wiring to the board….

    Motor wire pairs are Blue/Green & Red/Black I connected there on ramps as 2A/2B & 1A/1B

    Can’t see any other problems, as I followed all steps by the books?
    Any ideas?

    Can we get a picture of the ramps as you have it wired right now?  Also, try hitting the home x button in repetier first.  The steppers won’t move backwards until you home it.  You can home x and y, just don’t touch the home z button.

    Does it make a buzzing/chugging sound when you try to move them?

    Usually that’s a wiring issue.  One of the pins in the stepper cables isn’t making contact.
