I've been completely blown away by the community that's been created by this project, and listening to all the comments and suggestions made - R3 was created. R3 keeps the same design goals as before, but since then a lot has been learned and areas for improvement have been highlighted. There have been many changes implemented on this revision, some radical and some minor, though all the changes have been implemented to increase configurability, rigidity, flexibility, accuracy, and also reduce the amount of different parts required. R3 supports the use of the largest NEMA23 motors and also the NEMA17 motors depending on the user's configuration. Its accuracy has also been increased by removing the second loop of belt on the Y-Axis while still keeping the two sides of the gantry connected together. The second loop of belt introduced a position error when a load was applied to the gantry, now there is only single belt length to increase its positional accuracy. By doing this made it difficult to keep the two sides of the gantry relatives to one another (something another 3D printed CNCs suffer with). Though R3's gantry sides are connected together, so no matter if the machine loses power or is disconnected the machine still stays relevant to one another to keep its running true and square. Belt or Lead screw? This has been an interesting topic but no matter what your preference is, R3 has provisions for a Lead screws as drive mechanism for both the X and Y Axis. This does require some of your own design work to fit the type of Lead screw the individual is running though the core R3 shouldn't need any modification and will work with Belt or Lead screws. Linear Guilds for the Z axis?! I know these aren't considered cheap but once all the variables and benefits have been factored in, they become a compelling option to use. Especially for the short lengths the Z axis requires. With the original design there was sufficient play in the carriage due to its minimalist design though R3 has attempted to remove or possibly of play with the wood panel and the use of Linear Guilds. But don't think this is the only limited to linear guilds, R3 keeps legacy support implementing the same linear bearing style design and also legacy Z carriages. Build one Please if you build one post some photos! I would love to see them!
