Multicolors 2D plotter adapter

prusaprinters

<p>Features:</p> <ul> <li>Easy to calibrate pen alignment and depth.</li> <li>Multicolors.</li> <li>Can be added/removed to the existing extruder easily.</li> <li>Uses magnets (8x2mm) instead of an elastic to push the pen onto the bed.</li> <li>Uses M4 screws and hexagon nuts.</li> <li>Should be relatively easy to use the same 'magnetized pen carriage' design for other printers (see 2D<em>Plotter</em>-_Anchor_Template.step file that could be included in other design).</li> </ul> <p>Video that shows the different part of the design 'in action': <a href="https://youtu.be/gprN2s9aOII">https://youtu.be/gprN2s9aOII</a><br/> Video of a "little prusa" drawing timelapse: <a href="https://youtu.be/bu7SffQJ6y0">https://youtu.be/bu7SffQJ6y0</a></p> <p>I included profiles for "Slic3r Prusa Edition" (that can be imported with "File\Load Config Bundle"):</p> <ul> <li>A new printer: "2D Plotter with Pens" that support multiple extruders. If needed, the number of colors can be increased by changing the value of "General\Capabilities\Extruders". Object needs to be 0.10mm tall (i.e. Max Print Height = 0.11mm).</li> <li>2 new "print settings": "0.2mm Pen Tip" and "1.0mm Pen Tip". It's usually better to use 0.2mm.</li> <li>2 new "filaments": "Pen" and "Pen with Calibration".<br/> [Note: I don't seem to be able to upload .ini file. It's available on <a href="https://www.thingiverse.com/thing:3573724">https://www.thingiverse.com/thing:3573724</a>)</li> </ul> <p><em>Tested with Prusa MK2.5 and MK3. Not sure yet if it fits the new MK3S extruder, I'll test it when I receive my upgrade.</em></p> <h3>Print instructions</h3><p>Only "2D Plotter for Prusa Printers (MK2.5, MK3)" need support, and I suggest to use "support blocker" to remove the supports where the screws nuts are placed, it's not needed. I included g-code for that piece that includes this 'partial support' baked in.</p>
