Review on 🖨️ Enhance Your Printing Efficiency with the OUYANG MGN12H Carriage Printer Machine by Richard Summerall

I bought these for one of my new 3D printers. I wanted to try the cheaper linear rails as the HevORT design requires 9 rails and the cost is increasing and was very surprised at the quality. I measured the error between the carriage and the rail to be no more than 20 microns, which is way more than a 3D printer needs, so I'll keep using them for my other builds. They move very smoothly out of the box so I added some super lube and installed it just in case. It comes with slide stops and is well packaged.
