Be sure to re-oil the rail after assembly. I know it seems obvious, but I honestly thought that there was still enough left on them to protect against moisture. I followed the guide as stated. I spread out some paper towels, and used paper towels to wipe down each rail. I didn’t thoroughly scrub them clean, or use any solvents, or anything like that. I just wiped off enough so that I wouldn’t get oil all over my gloves after picking up a rail.
About a month later I noticed that there was a light amount of rust starting to form on the tops of all my rails. The printer was not exposed to any water or hardly any moisture at all really. In fact, it sat in a very well air conditioned room, very dry. I used some 000 steel wool lightly on the top of the rails to remove the rust. I then rubbed in a decent coating of Super Lube 52004 to all of the rails. If anybody has a better oil to suggest please let me know. The 52004 is dielectric, non-PTFE, and an ISO of 68.
As Daniel noted, be careful screwing this piece down as it is very thin. On top of that, check for a lip between the XY joiner and the linear rail. In my case, the joiner was too short. I didn’t notice until screwing down the piece and it cracked under almost no force. The linear rail stuck up above the joiner by about 2mm. That lip combined with the very thin piece almost guaranteed that the endstop wasn’t ever going to be secured very well.
I would recommend not attaching the Y endstop at this point. This piece tends to stick out a bit and is just too easy to bump into during the rest of the assembly process. Twice, in my case, I accidentally elbowed the switch. And one time my shirt sleeve caught the metal lever and almost broke it off. I was able to pop it out and bend it back into place thankfully.
If you wait until the very end, after everything else is assembled, that would be a better point to attach the Y endstop to the frame. Nothing will be in your way, nothing will make it any more difficult to attach later as opposed to at any other point during assembly.
