Pen lifter for CNC Plotter

prusaprinters

<p>This is the front part of the CNC pen plotter shown in the pictures.<br/> Please refer to the YouTube video for seeing the design in action.</p> <p>It uses a 9g Servo to move a pen up and down.<br/> Pen is fixed with two cable ties.<br/> In the middle I used aluminium tubing (OD 6mm, ID 4mm).<br/> All the parts are aligned with one piece M3 threaded rod, components hold on positions with a couple of M3 nuts. The spring keeps the pen pushed to the paper in idle mode.<br/> Attachment of Servo and of the assembly itself to the CNC plotter is done with some hot glue.</p> <p>Designed in Onshape;<br/> public link to CAD - source files attached:<br/> <a href="https://cad.onshape.com/document-redirect.html?d=/documents/9158d083cabd84b78d2e0afb/w/46fec7ef818f30d1c785996b">https://cad.onshape.com/document-redirect.html?d=/documents/9158d083cabd84b78d2e0afb/w/46fec7ef818f30d1c785996b</a></p> <p>See fully assembled CNC - Plotter in action:<br/> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=xJS5MQ620vE"></oembed> </figure> </p> <p>Goes together with this design:<br/> <a href="https://www.thingiverse.com/thing:2746214">https://www.thingiverse.com/thing:2746214</a></p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anet A8</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>26</p> </p></p> Category: DIY
