    Hi everybody!

    I'm struggeling with my first 3D-printer right now. I bought a E3D BigBox and oh my god it took for ever to assamble it. But now I'm pretty much done with putting it together.

    This problem I have right now is that I can't get it to calibrate correctly. All axis move very smooth and easy but when I hit "Auto home" its moving the nozzle to X = 215mm and Y = arround 80mm. Which is way of the center.

    I zeroed the both axis already and alos checked the stepper drivers for the right voltage. Belts are also under tension and steps/mm are also on the default values.

    Would be nice if anyone could help me out.
    Thanks!

    Auto-Home with the standard firmware is 150x100 for the IR SENSOR.
    don't get confused with this.
    Also, it's the right nozzle which should be able to hit the 0x0 mark, also a common mistake.

    Take a picture, it says way more then a thousand words

    Well I have the single extruder version.
    Here is a picture of where it stops. Y is more like 50mm and I can't move it all the way up manually. Also moving it 10mm won't move the head by 10mm its way less than that.

    Did you use the correct pulleys on the Y and X motors?
    To get all the way to X0 even manually you might have to adjust you endstop screw or use a shorter one...

    X0 an Y0 are working fine and the stop screws are set too. I think I use the right pulleys. More pix are needed I guess ;-)

    Can you count the number of teeth on pulley of the 1st picture?

    It think there are like 24 teeth. Its a bigger one. All of the ones at x axis and the y axis look the same. the only one that looks different is the one at the stepper motor of the Y axis.

    Ok it's got to be 20 teeth then. Because the ones from the Y axis are 8mm ID and wont fit to the stepper. But anyway the stepper motor you mentioned is the one for the X axis. But the X axis is working fine. It's the Y axis I'm having issues with.

    Still, your pulley is mounted upside down.
    Can you move your carriage all the way up Y axis when you remove the left side ribbon?
    Idem ditto for the right side?
    Perhaps also measure the distance in the front and the back, are those simular or different (+1cm something)
