ReliaBot Linear Carriage Printer Machine: Advanced Power Transmission Solutions for Optimal Performance Review

Updated my 3D printer to use these linear rails. Arrived clean and smooth. Initially 2 of them were not flush or fully linear in terms of extrusion but went flat immediately after installation. I bought some "Super Grease" to apply after installation. I can recommend these.

This is the fourth linear rail I have purchased from Revain. All were on the lower end of the price scale, and the other three definitely showed it. But this rail, this rail is surprisingly good. The packaging is decent, the rail is very straight, the block slides easily and doesn't stick. I will still clean and re-grease the block to make sure it is properly lubricated but I am very happy with my purchase. My Hypercube Evo will soon be happy too!

My splint arrived on time and well protected, but the splint itself is crooked in the middle. I'm sure it bolts well to the aluminum profile, but in my application the rail isn't supported and so the rise in the middle when measuring the bed rail is quite noticeable. I thought it was a mistake but I attached a ruler to my glass bed which was straight and smooth. When I applied the same straightedge to the linear guide, the deflection I found corresponded exactly to the mesh size.
