HyperCube Evolution: Ultra-Compact optical endstop for Z axis

<h1>Project Files and Photos</h1> <p>I've encountered an issue with the Thingiverse service not displaying previews for photos attached to projects. After trying different formats for three days, I was unable to resolve the problem.</p> <h2>Project Overview</h2> <p>This project involves creating a custom optical sensor bracket for my 3D printer's table frame. The goal is to achieve precise positioning and reliable operation of the optical sensor.</p> <h1>Bill of Materials</h1> <ul> <li>M3x8mm screw, DIN7991 - 1 piece (for endstop PCB)</li> <li>M3x6mm screw, DIN7991 - 2 pieces (for breaker and guide)</li> <li>M3 washer, DIN125A - 1 piece (for breaker)</li> <li>M3 nut, DIN555 - 3 pieces</li> </ul> <h1>Installation Tips</h1> <ul> <li>Lower the table frame below the beam 3030 into which the optical sensor will be installed. Install the optical sensor in the slot on the 3030 beam, but do not tighten its mount tightly. You should be able to move the sensor along the line of the slot.</li> <li>Assemble the breaker and guide plate onto the double T-nut without tightening the screws. Insert the assembled assembly into the groove on the 2020 profile. Tighten the screws, but do not tighten the mount. You should be able to move the double nut, guide plate, and breaker along the slot line. Temporarily move them closer to the middle of the table so that the breaker is guaranteed not to touch the sensor when lifting the table.</li> <li>Carefully raise the table a little. Make sure the table frame does not touch the sensor housing. If necessary, further reduce the thickness of the sensor mount using a file. Make sure that the table frame never touches the sensor body when moving.</li> <li>Move the table so that the top edge of the breaker is opposite the gap in the sensor. Move the sensor and breaker to the operating position. Tighten the screws of the sensor and the breaker (but do not yet tighten the screw that secures the guide plate!), making sure that there is minimal clearance between the sensor and the breaker, and that the breaker does not touch the sensor. Make sure the switch is upright.</li> <li>Move the table and make sure that the breaker reliably covers the sensor gap and does not touch the sensor when moving the table.</li> <li>Pressing the guide firmly against the breaker, tighten the guide screw.</li> <li>If necessary, loosen the breaker screw (only the breaker, but NOT the screw of the guide plate!) and adjust the vertical position of the breaker, making sure that the sensor works in the correct position of the table.</li> <li>Once again check the operation of the table and the correct positioning of all the parts, and then finally tighten all the screws.</li> </ul> <h3>Additional Photo</h3> <p>The full photo album of my printer is available at:<br><a href="https://photos.app.goo.gl/VJPtnTUTJLTdHh8EA">https://photos.app.goo.gl/VJPtnTUTJLTdHh8EA</a></p>
