Axis Tensioner - Y axis

prusaprinters

<p>Getting the Y axis belt tight enough can be a real pain. That's why I've designed this printable upgrade to allow increasing the tension on the Y axis belt / pulley by turning a screw.</p> <p>You can find my X axis belt tensioner here <a href="https://www.thingiverse.com/thing:1673">http://www.thingiverse.com/thing:1673</a></p> <p>V1 - Based upon a single captive nut.<br/> V2 - Fixing an alignment issue.<br/> V3 - First printable version. The smaller piece that holds the captive nut was too long.</p> <p>2010-01-23<br/> V6 - Same concept, but a different design using two captive nuts on each side of the Y axis pulley. My test print is suffering from some X stage problem, so the prints aren\'t coming out right yet. However, I wanted to post this in case I could get feedback from others.<br/> 2010-01-25<br/> V7 - Same concept with a few improvements.</p> <p>I created the screenshot from Unrepentantgeek\'s Sketchup version of the Cupcake CNC. <a href="https://www.thingiverse.com/thing:1449">http://www.thingiverse.com/thing:1449</a></p> <h3>Print instructions</h3><p>Unassociated tags: y axis, Makerbot upgrade part</p> <h3>Instructions</h3> <p>There are two pieces in this one STL / Sketchup file.<br/> The smaller piece should fit around the hex nut under the Y axis pulley. The second piece should fit around the edge of the Y axis.<br/> Drop two M3 nut into the slots in the smaller piece that fits around the Y axis pulley.<br/> Insert two M3x16 bolts.<br/> Tigthen.</p>
