    In the guide it says "Tip: To get the nut through the round hole drop it in the hole, then use the end of an allen key to level it and use a fixing from the rear to pull it into place." However, when I do this I can't get the nut to stay in place; it just falls out again.

    I haven't got that far in the build yet - just working my way through the parts preparation, so I'm not sure how important it is to get those nuts to stay in place.

    Does anyone have any tips / advice, or should I just ignore it?

    Thanks!

    I dropped the nut in and got it as flat as I could. I then took a long M4 screw, longest I could find in the kit (M4x20 ?) and pushed the allen key end in as far as I could to hold the nut flat, at the same time i screwed an M4 bolt in the back, all the way, to pull the nut into its final place.

    I did that, and screwed it in to place, but they just didn't want to stay in place. I guess it's possible that I was just tightening the bold against the plastic, rather than pulling the nut back far enough - it's hard to tell.

    I'll try giving it another go.

    Thanks @PsyVision, you were right - I was just being too cautious to not overtighten / break the plastic. I just tried again, and pushed each of the nuts further back, and they're all wedged in nicely now!

    Good that you did that. When it came to tightening those screws at the commissioning stage, I figured out I didn't have them in quite as far as I thought I had. I wasn't all that excited about what followed, but was fortunate to get them sorted without dissassembling the whole XY setup.

    I did the same. It was awful if anything I think it'd be worth gluing these in like you do with the nut traps

    I would agree to glueing them. That said, I think the reason they fell out for me as that I hadn't seated them far enough. If I had put the screw through and pulled them back and back and back, eventually they would have been tight in. Accidentally glueing them in a position that wasn't all the way down, or that was not quite at the right angle, could cause more frustration. Imperfect situation. Warning people is maybe the best thing.

    After the second time they fell out, I pulled them into place with a long screw, and then with superglue on the end of a piece of nylon wire tie, pit a dot (VERY CAREFULLY) onto the side of the nut onto the side wall of the piece. Worked perfectly. (actually I left out the stream of very bad words between those steps)

    I fabricobbled a slip of credit card and double sided tape to hold the rear bottom one while I got it back in. It was a thing to behold. :D
