    well , following the red and black wires  are they  power supply for both sides ?
    in that case what´s the brown and black wire?
    are you shure you didn´t swap something?

    Red fuse:
    Red and black --> PSU

    Blue fuse side:
    Red and Black --> Heatbed
    Brown and black --> PSU

    Ok, unusual but if you are shure it´s ok
    did you check the red fuse?

    may be you can borrow one in your neighbours car ;-)

    Okay, I'm officially retarded.
    Checked again, unplugged the wires, followed them and...


  • RAyWBRAyWB
    thats what it should look like...
    and motors turning / heaters heating now?
  • unf0rg0tt3nunf0rg0tt3n
    Yes! the heaters are heating, the X, Y and Z steppers work but in the opposite direction :D So I have to swap the wiring again nothing special. the stepper is making a machine gun sound like it's choking on something, but I had that before, so easy to fix.
    So I guess all is up and running and maybe at the end of next week I will be able to print.
  • RAyWBRAyWB
    ok, so keep in mind never plug/unplug motors in powered system, that can / will fry your stepper drivers.

  • unf0rg0tt3nunf0rg0tt3n
    Thanks! I won't unplug anything from a running system :) that's how I am raised ;)

    Got the steppers going the right direction again.
    E1 still is stuck.
    another stepper, same port:

    By my guess my stepper got broke or the V-ref is not set properly because it's on 1.6V and stepper is rated at 1.8V

    did you enable cold extrusion?
    otherwise stepper will not move without heat

    M302 S<0 or 1> - allow cold extrusion. Without S parameter it will allow. S1 will allow, S0 will disallow.

  • unf0rg0tt3nunf0rg0tt3n
    Yes one of the steppers is working as seen in the video :)
  • RAyWBRAyWB
    did you try to measure wire and coil resistance?


  • unf0rg0tt3nunf0rg0tt3n
    Nope, but I did use the same wire on 2 other steppers those worked.
    I also tried the E0 and E1 pins; that didn't work
    I used 3 different wire sets also that didn't work.

    The only stepper not working is the second stepper in my video.
    The first stepper in the video did work but is from some old zebra printer and is rated at nearly 4 amps.

    How would you suggest checking the resistance in the wire and coils?
  • RAyWBRAyWB
    can you upload a pic of the not working motor?
    (connector and nameplate)

    Sure:



    and


    nothing modified, straight out of the box

    ok so there are two coils , the left two wires should be one and the right two wires the second.

    can you measure resistance with multimeter (lowest ohm range) of each coil and compare to the working stepper?

    (use same cableset for measurement)
  • unf0rg0tt3nunf0rg0tt3n
    Really strange...
    The working stepper has 1-2 as coil and 3-4 as coil.
    On the other hand the non working stepper has 1-3 as coil and 2-4 as coil.
    For the non working stepper it makes a lot of sense that it doesn't work since the coils are working against one another.

    so if you swap  2 and 3 in cable  on radds side this motor should also work

    Yes, All works now! really smooth and well :) thanks!
    Now I'll need to finish up with the touch screen and such and then I'll post a picture of the finished product:)

    Working!
