Tevo Tarantula Dual Stepper Inverted Z

Made specifically for the TEVO Tarantula but can be easily adapted to any T-Slot/V-Slot extrusions. The platform height is precisely 5mm and works seamlessly with parts such as these: https://www.thingiverse.com/thing:2039503. I utilize this carriage (https://www.thingiverse.com/thing:1839201) for the original or other horizontal arrangements, and below are listed several remixes that can be used instead. Designed to work in conjunction with 48mm Nema 17 steppers. If you decide to use a different size motor, it's recommended that you adjust the posts on the base sections accordingly. The small holes located on top of the oldham couplers provide an easy way to apply lubrication. The Oldham middle sections require additional support, while the rest can be printed as is. It's essential to sand the oldham sliding sections using 600 grit water paper for optimal results. Additionally, take note of the way the lead screw nuts are mounted in the rendering, which prevents them from coming into contact with the flexible couplers at their lowest point. To ensure smooth movement, place 608zz bearings in the brackets that guide the Z screw. For firmware settings (Marlin), you'll need to make the following adjustments: configuration.h: Set this parameter true #define INVERT_Z_DIR true configuration_adv.h: Uncomment these lines #define Z_DUAL_STEPPER_DRIVERS You can also use these other brackets for added support: https://www.thingiverse.com/thing:2377413.
