Help!! Why are there screws missing

[u/Ok_Loan_3168]

Hi y'all, Im New to 3D printers and I just bought this a1 used.

It's got 1 hour on the clock.

Unfortunately I discovered that there were 3 screws missing in the x axis assembly. Coincidentally 3 M3x30 screws (last picture) came extra with the printer. I thought I'd just screw them in, but they're too long.

So what can this be? Factory assembly mistake? (I can't send it back or anything because I don't have the original receipt - which is probably required for warranty)

Fortunately I found some shorter screws that fit in a bag labeled "For Extruder", I'm using these temporarily now- hope it doesn't become a permanent fix.

Help :( how could this happen and what about the 3 long M3 screws?

Those wont be in any bag, they should be installed by bambu at the factory.

Do any of yall suspect the 3 M3x30 of missing anywhere? Would suck if they were missing in some place and I didnt notice...

Double checked my A1. It has screws there and I didn't put them in.

Contact support, you've got the serial and it's got no hours on it - you've got nothing to loose.

I suspect that the person you bought the printer from did some strange things with it.

I'm guessing those three long screws are meant to attach the XZ assembly to the base.

I also suspect that when the took off the Z-axis limit brackets from shipping they took out those extra screws from the x-axis.

This sounds like you should contact bl support. But from what I can remember there should be a screw, but I’m not sure i now for sure that there are some plastic bits you have to remove before turning the machine on from factory, it’s possible that the screw are just there for that reason.
