Yet Another Core XY

thingiverse

DESCRIPTION: My own version of the Core XY printer is a DIY project that showcases my creative take on 3D printing technology. The hotend is a low-cost J-head with a bowden configuration, modified to allow the Teflon tube to pass through the heatsink and reach the heater block. This design provides superior heat dissipation and minimizes thermal stress on the components. The heater block itself is covered in a layer of high-temperature-resistant silicone, commonly used in engine applications, to ensure optimal performance and longevity. The Z-axis features a simple yet effective threaded rod with a wobble and backlash suppression system in place. The Z motor is mounted upside down, which stretches the rod rather than compressing it, and an additional axial bearing is integrated between the coupling and the Z-bearing holder to absorb the weight of the Z carriage. USE HIGH-QUALITY BEARINGS AND RODS! For the extruder, RAMPS case, and LCD frame, please refer to my other projects for detailed information. The complete 3D model of the extruder is available for download in STL and STEP file formats. If you require the original Creo Parametric files, I can provide them; however, please note that I use the Academic version of Creo 3.0, which may not be compatible with commercial versions.
