Received wrong motors

Dear all,

I have a question relating the X, and Y - motor. I think I received two wrong motors with my Ultimaker Original kit. All the motors with the long wires have a flattened axis (see the attached pictures).

Does anyone of you know if I can still use them as X, and Y- motors or should I really have the round axis instead?

If the latter is the case does anyone have a suggestion with which step I can continue my build?

That would be really helpful!

    You can use those motors, if the wires are long enough. Just make sure you do NOT fasten the pulleys on the flat part. So the grub-screws in the pulleys should hold the axis on the round part, else you will get print quality problems.

    Daid, I would have thought the opposite and have the grub screws pulling the pulley to the round part of the shaft ensuring it is concentric. Plus it would be impossible to have the pulleys slip.

    Could you explain a little more why not using the flat is better for print quality?

    Because if you put the grub screws on the flat parts, you will never get it 100% aligned with the flat part, so there will always be a tiny bit of play.

    We had 1 machine 1.5 year ago which had motors with flat axis, took us forever to find the cause of the problem.

    Thanks for the reply's!

    I also submitted a ticket and it all will be arranged, I will receive new X, and Y - motors from Ultimaker.

    Cheers!
