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: (affiliate link) Aliexpress: or here for Hiwin: For black oxydized linear rails check the ones from RobotDigg I used them om my DIY Voron Switchwire 3d printer shown here , and they were quite cheap for the quality. Other parts and printed parts: Y axis: 2x460mm 2020 extrusion (buy 1m and cut it) Gates-LL-2GT 9mm belt 100cm (I bought 110cm to have some extra) 2020 aluminum profile triangle connectors 9 or 10 mm timing belt pulley (5mm bore) 20 teeth 9 or 10 mm idler 20 teeth Printed spacers 7mm (link soon) Printed Y endstop&stepper holder :4263402/files Drilling template :4263379 Y tensioner for 9mm belt: :3478466 Check also this alternative solution for the Y axis if you want to avoid drilling the hotbed support (comes with Hiwin rails at good price): X-axis: 2xM3 idlers 16 teeth 1xM5 idler 20 teeth Modified X tensioner, Carriage for MGN12 and MGN9 and modified “Tank” print head, Modified front X motor plate: :4257905 This direct drive is for BMG or Trianglelab dual drive extruder: // Check also my adaptation of the Voron Afterburner direct drive for CR10 if you want different print head: :4304916 - see it in action here // Z-axis: Mounting elements for the right side of the gantry: :2974225 :3742027 (CR-10 only, alows to implement dual Z with one stepper) Mounting element for the left side: :4258451 Frame braces: :3119088 modified top right part (for CR-10 and dual Z with 1 stepper) – :4263398 You will need also some M3 bolts and nuts with various sizes, M3 T-nuts (buy at least 50) and M5 T-nuts (buy set of 20)
