I have started hearing a "clicking" sound when I move my Y axis manually, it sounds like it is coming from one of the carriage blocks. I don't notice any difference in the ease of movement of the Y axis yet. The rails have been lubed. But I was wondering what linear rails are used on the FT-5, from my little bit of research it looks like I could use a MGN12 400mm linear rail guide, and a MGN12H carriage block. I was thinking about buying a new linear rail guide, and carriage block, and another carriage block to fix what I think is a bad carriage block on the current installed rail. Any advice would be appreciated. K
