Z-lead nut doesn't fit

Posted · Z-lead nut doesn't fit

So when I opened my UMO+ kit the Z-lead nut was already on the Z-lead screw rod (z-axis). It was really stuck on there (almost like it was seized in place) but I managed to get it off so I could attach it to the heated bed plate.

However, even after greasing the Z axis screw the nut just won't move up and down it smoothly, making the aligning of the linear bearings on the heated bed impossible (and, I imagine making it very difficult for the machine to move the bed up and down).

Is there anything I can do other than ask Ultimaker for a new Z-lead nut? I've raised a ticket but I have no idea how long it's going to take, this printer has already caused me enough problems, I just want to get it working.

    I have been in a similar situation. Eventually it will work itself out.

    I might not do anything until UM decides what they think needs to be done. Anything drastic might complicate the trouble shooting process.

    If I were going to try something, it might be soaking the nut in some PB Blaster and wiping down the rod as well. Then clean em off and put more grease on. The nut should turn very easily. Mine turns so easily that the bed will sometimes slide down on its own when the motor powers off.

    I don't use the grease UM is providing with the UM2. I prefer a slightly thinner fluid (actually a high-quality oil for bicycle chains) and it runs very smoothly. Maybe you have to oil or grease it, clean it and oil/grease it again?
