The best upgrade
This rail upgrade kit is the best thing I’ve ever done for my ender S1 pro. Since putting on the rail kit, I haven’t had any issues with my auto bed, leveling, causing a wavy mesh due to the poor roller design and uneven stock rail on my ender S1. It’s super easy to put together creates such a tight fit and eliminates so much play in the printhead that I consider this unnecessary upgrade for the ender s1 and s1 pro

Solid.
I got the X Y and Z linier rail kits for my ender 3 s1 pro. Instructions were clear and it is a well build kit. Mark improvement on the xy axis(didn't like the delrin wheels). Thank you GC for making a good kit.

Take care cleaning rail
Be careful when cleaning the linear rail. The stopper plug got knocked out of the end of the rail and the cartridge came off the rail. I lost one bearing and I'm now looking for a replacement cartridge.Otherwise I'm pleased.
