Do linear rails improve print quality? On paper, yes. In this video we find out about actual results with before and after test prints.
In summary, linear rails offer little in improvement for a really well set up machine. They still have a purpose and if you are going this way, these are quite good kits. The quality is nice and the modular nature means you can switch over a little each time or all in one go. You also have a choice of how much to spend on linear rails and blocks.
Linear rails might have more of a benefit when switching to a heavier direct extruder, or perhaps when pushing high prints speeds.
These kits and rails supplied free of charge for the purposes of conducting this test. All opinions expressed are my own.
Purchase these kits from www.printermods.com :
