I'm amazed at how well these things work. Â They're a little stiff at first, but they loosen up with use. Â Also, I find that TPFE lubricant like Labelle #134 works wonders. Â I have a chain ready with end mounts to install on my y carriage, and I'm trying to figure out a way to handle the x axis.Â
I am also thinking of using them for my Z axis - not because there is any particular need - I just think it looks cool.
