I'm at the Z-Axis Bed Assembly step of the build and I'm wondering how to fix the brass nuts to the panel. Do I need to fix the screws with a nut? When i stick the M3 10 mm screws through the holes of the nut and panel they barely protrude through the nut and panel and just sit there. They don't screw in and as a result fall out when I flip the panel over.
You might be using m3x8 screws, there are some in the kit, also make sure you are using the m3 holes and not the m4 ones
The nuts go in to the two round holes on the short sides of the plate, right? There are four holes around the centre hole where the nut is put in. Those are all the same size. A m3 will not screw in and a m4 does not fit.
The brass nuts the lead screws run in have 8 holes round the circumference. 4 are threaded to accept the screws so no additional nuts are needed.
Building a v1.1 and running in to a problem where the M35 screws aren't log enough if I use the lock washers. With a lock washer the M35 barely extends past the bottom, without a lock washer it's just enough to take a few turns against a half-nut. I'm thinking about leaving the washers off then using Loctite medium or low on the nut. Edit: looks like the etching wasn't deep enough for the nuts by about a mm. I replaced the tooth washers with spring (Belleview) washers and it's close enough.
I believe I had that issue and you are supposed to use a longer screw... i thought they fixed that in the manual though...
