Asterion easy and cheap 3D printed full screw CNC machine

!!!PLEASE NOTE!!! This is WIP... Altough it works perfectly fine it still hasn't completed its first milling operation, just some drawings. Homing couldn't be tested yet either due to a broken Uno. Altough I see no issue resulting in total failure, this machine is still in its testing phase. !!!PLEASE NOTE!!! Asterion is a cheap and easy to build CNC machine featuring lead screws on all axis. When I decided to build my own CNC machine I knew it had to be cheap which meant that the stepper motors I could afford, would be very weak. Altough there are many belt variants like the MPCNC or Root 2 around, I wasn't able to find a good full screw CNC machine design. Therefore I designed my own machine based on the Root 2 idea. The only part used from this machine was the linear guide for the 25x25 mm aluminium square tube. Its total cost without the spindle and the used filament is around 125€. If you want to rebuild this machine, please refer to the BOM (bill of materials) and assembly instructions in the attached .zip folder. If you want to use parts of the machine for your project, please refer to the parts description (PD.txt) in the attached .zip folder. You should find the specifications for the most important parts there. The parts with a larger footprint come in a brim and a brim free version. For printing on machines with warp problemes I can recommend to print the brim design directly on the glass surface.
