Manual CoreXY Mechanism

thingiverse

This is a small-scale, budget-friendly ($10 or less) CoreXY mechanism that demonstrates how CoreXY functions. When the user turns both knobs in the same direction, the X-axis moves into action. Conversely, when turned in opposite directions, the Y-axis takes center stage. Keep in mind that this setup is purely illustrative, as there are no current attachments for a pen or pencil (or laser or extruder). Nonetheless, the concepts learned from this project can be scaled up and improved upon, paving the way for the addition of stepper motors. To build this mechanism, you will need: * 4 x 3mm by 100mm aluminum rods (other materials may also work) * A 1m GT2 timing belt measuring 6mm in width (a thinner belt would suffice) * 6 x 3mm x 25mm (or longer) screws To print the parts required for this mechanism, you will need: * 1 x Inner bearing * 2 x Outer Bearing * 1 x Frame * 4 x Spacers * 8 x Spindles * 2 x Control knobs * Optional: 2x Belt Connectors In my build, I used PETG material, but any suitable material should work. I opted for a 20% infill, but recommending 65% would be wiser, as it doesn't significantly extend printing time. Check out this video showcasing the mechanism in action: https://youtu.be/tElMsCfxDCs
