<h5>Attention: Your printer needs to be calibrated correctly in order to print accurate!</h5><p>Only 0.05mm offset to the components.</p><h5>31.01.2022 - Added Leadscrew jig, might need some more testing!</h5><p>&nbsp;</p><h3>RatRig V-Minion alignment tools</h3><p>In order to fit the rails perfectly for the printer I've designed some tools to help a lot with this. Designed with a lot of rounded corners to ensure fast print speeds (we don't want to waste time don't we?).</p><h4>2 Versions available - with holes and without</h4><p>The holes are there to tighten the rail without the need to move them away!</p><p>&nbsp;</p><h4>Z axis assembly</h4><ul><li>1x 3060MGN15_Alignment_Jig_top.stl</li><li>1x 3060MGN15_Alignment_Jig.stl</li></ul><p>The top part goes onto the side of the 3060 extrusion to secure the rail and ensure the needed 5mm offset as instructed in the build guide.</p><ol><li>Slide the printed top part onto the 3060 extrusion</li><li>push the rail into it (while holding the printed part).&nbsp;</li><li>This should ensure the 5mm offset from the top of the 3060 extrusion is correctly applied.</li><li>Use the other part to align on the other side</li></ol><p>&nbsp;</p><h4>Y axis assembly</h4><ul><li>1x 3030MGN15_alignment_jig_top.stl</li><li>1x 3030MGN15_alignment_jig.stl</li></ul><p>The top part goes onto the opposit side of the stepper motor. Then the same procedure then on Z axis.&nbsp;</p><ol><li>Slide the printed top part on the 3030 extrusion</li><li>push the rail into it (while holding the printed part).&nbsp;</li><li>This should ensure the 5mm offset from the top of the 3030 extrusion is correctly applied.</li><li>Use the other part to align on the other side</li></ol><p>&nbsp;</p><h4>X asis assembly</h4><ul><li>2x 2020MGN12_alignment_jig.stl</li></ul><p>This is a normal 2020MGN12 alignment tool. Print 2 to place on both sides of the rail. The other printed parts of the v-minion ensure the correct offset.</p><p>&nbsp;</p><h4>Leadscrew alignment</h4><ul><li>1x 3060MGN15_V-Minion_alignment_jig_leadscrew.stl</li></ul><p>This jig can be used to align your leadscrew accordingly. The best way is to slide it from the top onto the rail. <strong>The leadscrew should slightly touch the jig, a minimal distance between the leadscrew and jig is possible too.</strong></p><p>&nbsp;</p><h4>Print Tips:</h4><ul><li>Print everything without support<br><img class="image_resized" style="width:41.46%;" src="https://media.prusaprinters.org/media/prints/119022/rich_content/487ed4ca-20f9-4fe1-b2c1-0626a6751d41/image.png#%7B%22uuid%22%3A%220a57e899-2970-4a03-84e0-31f4f66e5ee8%22%2C%22w%22%3A513%2C%22h%22%3A423%7D"></li><li>Be sure to print it with a suitable nozzle size to ensure the corners and small parts are correctly in size</li><li>Line width for example: 0.4</li><li>Layer height: up to you, but needs to archive 5.0mm</li><li>Use some more infill then usual to ensure a durable printed part (30-50% is enough)</li></ul>
