Manual CoreXY Mechanism

youmagine

This is a compact, cost-effective (<$10) CoreXY mechanism that showcases how CoreXY operates. When the user turns the two knobs in the same direction, the X axis moves. Conversely, when turned in opposite directions, the Y axis moves. This setup serves as a demonstration, but it does not currently include an attachment for a pen or pencil (nor laser nor extruder). Nonetheless, understanding the principles behind this design can facilitate scaling up and making improvements, including adding stepper motors. Required materials: 4 x 3mm by 100mm aluminum rods (alternative materials may work) 1m GT2 timing belt 6mm (a thinner belt should suffice) 6 x 3mm x 25mm (or longer) screws To print the mechanism: 1 x Inner bearing 2 x Outer Bearing 1 x Frame 4 x Spacers 8 x Spindles 2 x Control knobs Optional components: 2x Belt Connectors I printed this model using PETG, but any material should be suitable. I used 20% infill, but a higher infill percentage of 65% is recommended to ensure stability, as it doesn't significantly increase printing time. Here is a video demonstrating its functionality:
