    Hi! I'm completely new to the topic and I apologize for asking dummy questions,
    but it would be great if you could help me anyway: I have a nema23- motor with a smooth captive shaft and I would need to transform it into a non-captive motor, so that I can insert a leadscrew in the inside... Is there a way I could do it without needing to buy a new motor? What pieces do I need ?

    Thank you very much for the help!

    There are various designs of shaft couplers with a different diameter going in & out. Do you know the size of both shafts?

    The internal diameter of the rotor (as the outer diameter of the shaft that I have now) is 0,8 cm, and I'd like to insert a leadscrew with approximately the same diameter

    Thank you, but I was actually looking for a screw, that goes through the motor, like this one in the picture.
    If I understand it right, the coupler you showed me is for external linear actuators.

    That's a threaded rod.

    You can do this with a new motor and integrated leadscrew of course, but ... on the Robo this is not a smart idea for X axis motors since the amount of space under the bed (the motors mount just above the bed) is not enough to allow you to move the rod full length. Y axis is under the bed (horizontal) and it could work there with some modifications.

    This is the correct way on the Robo.
