Quiet those end caps

[Nicolinux 288]

Hi,

I have printed these end caps from Thingster to minimize the play on the x/y rods.

It works very nice but these things are loud. The tip of the M3x20 screw scratches against the top of the rod. It produces a very high pitched screeching sound. Any idea how to get rid of it? Lubrication won't work because it would wear out too fast. Maybe put something in between - but what?

if you put too much tension on it, they will make plenty noise, plus add to the friction of the system.

have you tried a liberal amount of grease? have you considered sharpening the screws a little bit to give them a point?

Yeah, endcaps are a real PITA regarding noise and assembly. I want to rebuild my axes to use printed internal spacers, like the UM2 does. It also uses flanged bearings so there's no risk of bearings coming loose once the internal spacers are installed.
