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?
Nop…just fibrillating…
Usually that’s a wiring issue. One of the pins in the stepper cables isn’t making contact.
Thanks, I managed to figure out the proper wiring!
The machine is now alive, will post video soon!
Thanks everyone for your help!
Hi.
So the wiring in the pic you posted is correct?
I’m troubleshooting too for yor same wiring doubt.
