Root 3 Heavy Duty Ball Screw Mod

Note: It would be awesome if you could share your make pictures if you use this design. Would motivate me to continue working on it. Thanks. Root 3 Mod: This mod increases the Z-axis height and converts the root 3 from belt drive to SFU 2005 Ball Screw drive. The Y mounts are self-aligning when using an accurate cut base plate, making parallel assembly much easier. The Y mounts self-align by using a lip on the bottom corner of the print, allowing the print to easily be mounted parallel to the other mount in the pair. To use the new Y mounts, you must follow this method when building your machine: [CNC Base Length] = [Ball Screw Length] [25mm box section length] = [CNC Base Length] - 200mm For example, if my build is: [CNC Base Length 1000mm] = [Ball Screw Length 1000mm] [25mm box section length 800mm] = [CNC Base Length 1000mm] - 200mm This mod is a work in progress as there are other parts that need to be shared for it to work. Be aware that these mounts are very heavy-duty and require a lot of filament. I printed mine using a 1.2mm nozzle, resulting in each print being around 1.2kg of PETG. I used cheap eBay filament to save costs and was pleasantly surprised with the strength and quality once dialed in. However, do not start this project if you cannot commit to using a lot of filament and print time. If you choose to upgrade to a steel base plate as I have, it's essential to ground the base to avoid electrical noise issues.
