Manual CoreXY Mechanism

prusaprinters

<p>This is a small, inexpensive (&lt;$10) CoreXY mechanism which illustrates how CoreXY works. When the user turns the two knobs in the same direction, the X axis moves. When in opposite directions, the Y axis moves. This is purely for illustration purposes, there is currently no attachment for a pen or pencil (nor laser nor extruder). However, the concepts learned from this can lead to scaling up and improvements and the addition of stepper motors.</p> <p>Required:<br/> 4 x 3mm by 100mm aluminum rods (or other material may work)<br/> 1m GT2 timing belt 6mm (this is overkill, a thinner belt should work)<br/> 6 x 3mm x 25mm (or longer) screws<br/> To print:<br/> 1 x Inner bearing<br/> 2 x Outer Bearing<br/> 1 x Frame<br/> 4 x Spacers<br/> 8 x Spindles<br/> 2 x Control knobs<br/> Optional:<br/> 2x Belt Connectors</p> <p>I used PETG but any material should work.<br/> I used 20% infill but use 65% to be sure, it doesn't take much longer to print.</p> <p>Here is a video of it working: <a href="https://youtu.be/tElMsCfxDCs">https://youtu.be/tElMsCfxDCs</a></p>
