<p>If your printer has a motion system based on V-roller wheels riding on V-slot extrusions, check they are properly tensioned. Each location will have one eccentric nut. This can be twisted to either add or remove tension on the wheels.</p>
<p><b>If the wheels are too loose:</b> Wobble will be present in the assembly, which will show in the print as surface artefacts.</p>
<p><b>If the wheels are too tight:</b> The assembly will be too tense, which will wear the V-rollers prematurely.</p>
<p>In some rare instances poorly adjusted rollers may affect first layer accuracy across the bed.</p>
<h4>Lubrication</h4>
<p>Lubrication is an important maintenance task to perform regularly. Components that are not adequately lubricated may bind and affect print quality. Use <a href="https://amzn.to/3aqLT0a" target="_blank">SuperLube Synthetic Grease</a>. Lubrication needs to be performed regularly on any hardened rods, <a href="https://www.youtube.com/watch?v=loBHYcifzRM" target="_blank">linear rails</a> and lead screws.</p>
