Complete linear rails conversion of CR-10 3d printer

Full conversion of a CR-10 3d printer to linear rails. On each axis I have 2 linear rails, including the X-axis. This is not needed, however I decided to do it for more rigidity and to be able to attach heavier direct drives. Here are the linear rails I used: Y-axis: 2x500mm MGN12 w. 2 H carriages Z axis: 2x 500mm MGN12 w. 1 H carriage X axis : 1x400mm MGN12H + 1x400mm MGN9H I bought the rails from RobotDigg and Hiwin (MGN12 on the X axis) and I am very happy with their quality. There are cheaper rails and maybe they are OK for a 3d printer, but I didn’t want to risk with noname brands. Check the linear rails prices: Amazon: https://amzn.to/2WYLP3p (affiliate link) Aliexpress: https://s.click.aliexpress.com/e/_d8x... or here for Hiwin: https://s.click.aliexpress.com/e/_d6a... For black oxydized linear rails check the ones from RobotDigg https://s.click.aliexpress.com/e/_9yOk2s. I used them om my DIY Voron Switchwire 3d printer shown here    • Voron Switchwire - 3d printer review and test  , and they were quite cheap for the quality.
