Root 3 Lite X conversion

thingiverse

UPDATE: 18-08-2020 I've added new and significantly improved Y-axis legs. The Legs are sturdier, and the belt is now secured with two M5 screws instead of three M3 screws. It can be screwed down from above rather than through the plate from underneath. Added a robust X-axis belt tensioner and X-axis rod enforcer in one unit. A belt tensioner was required because I wanted to make it more rigid and use 9mm belts instead of six millimeter ones, as well as a finer method of tensioning. Ever since I saw the design of the Root 3 Lite, I've wanted to create it and customize it with linear rails for the Z-axis. So, I did! Ive customized some other features in the process and thought maybe others would like these customizations, so I'm sharing them. First, I created a board plate for the Z-axis linear rails MGN12. I combined measurements from the R3 Lite and the design of the R3 into a Root 3 Lite X design. The board is made from multiplex, but I'm considering upgrading it to Trespa for added rigidity. I'm using a 1.5-kilowatt watercooled spindle. Since the Root 3 has a lower Z-height, I also adjusted the bearing holders to make room for an extra twenty millimeters of Z-height. I removed the double bearing and made a single one; it should be sufficient. This design works with the original spindle holders from the Root 3, so I didn't have to redesign them from scratch. Since I've made my Root 3 Lite eighty by eighty centimeters, I wanted to reinforce the leadscrew with an extra bearing to prevent it from bending. It's a pretty simple solution but effective in preventing the leadscrew from bending under load. I added a drag chain holder to use with a larger dragchain. Mine was sagging on the original attachment, so I used a Dremel to remove that and attached this one to the backplate using M3 screws. I hope you enjoy these modifications! To-Do List: Make a backplate like the Root 3 for the Lite for added rigidity on the Z-axis.
