<p>This is a simple penholder for your Prusa i3 mk2s printer.<br/> It will convert it into a fully functional Pen plotter without disassembling anything.</p> <p>The Slic3r settings are given. (See the PenPloter_Slic3r_Config.ini and config_Bundle files)<br/> Use it :</p> <ul> <li>launch the gcode</li> <li>when first beep, position the pen and the rubber band</li> <li><p>30s later a second beep tells that printing will start That's it !</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=3mklWhb0VZg"></oembed> </figure> </p> <p>and details</p> <p> <figure class="media"> <oembed url="https://youtu.be/acarCoNSVMY"></oembed> </figure> </p> <h3>Post-Printing</h3> </li> </ul> <p><strong>final setting</strong></p> <p><div><p>add 4mm screw which will "auto tap" into the pre drilled holes on the pen holder<br/> add 2 nuts+screw to fix the holder on the extruder stepper motor</p> <p>add a rubber band, one end on the filament spring screw, the other on the pen holder</p> <p>position the pen and put the cap so that the tip touches the paper when z = 13.5mm (or modify the parameters into the slicer program...)</p> <p><strong>convert image or svg to stl</strong></p> <p><div><p>use on line tools such as :<br/> svg : <a href="http://svg2stl.com/"></a><a href="http://svg2stl.com/">http://svg2stl.com/</a></p> <p>svg : <a href="http://3dp.rocks/lithophane/"></a><a href="http://3dp.rocks/lithophane/">http://3dp.rocks/lithophane/</a> (flat model, positive image)</p> <p>bitmap : 2D image to STL : <a href="https://www.thingiverse.com/thing:66115"></a><a href="https://www.thingiverse.com/thing:66115">https://www.thingiverse.com/thing:66115</a></p> <p>Now you have a stl file</p> <p><strong>Slic3r configuration and settings</strong></p> <p>see images into the "thing files".<br/> You will need :</p> <ul> <li>cut the stl to only keep one layer</li> <li>set the PrintSettings with only 0.1mm layer, one single layer, no bottom/top layer, one perimeter</li> <li>set the filament to cut all temperature (bed and extruder to 0°C)</li> <li><p>set the Printer Settings into the Start G-Code section --&gt; IMPORTANT TO DO IT<br/> and add these lines : M115 U3.1.0 ; tell printer latest fw version</p> <p>G28 W ; home all without mesh bed level<br/> M104 S0 ; turn off temperature<br/> M140 S0 ; turn off heatbed</p> <p>G1 F600 Z+13.5 ; Raise the print nozzle out of the way<br/> G1 X00 Y10 F1000.0 ;position the pen so that it touches the bed<br/> M300 S1567 P240 ; Play a Beep<br/> G4 P20000 ; pause for 30s<br/> M300 S1567 P240 ; Play a Beep<br/> M117 5s remaining ; One minute remaining warning<br/> G4 P5000 ; pause 5s more<br/> G1 Z13.2 ; goes down 0.3mm pen can write now<br/> G92 Z0.2 ; Set absolute positioning for remaining print<br/> G92 E0.0<br/> G1 Z5 ; pen up before moving</p> <p>In this example, the pen is positonned so that the tip touches the paper when Z is 13.5mm.<br/> Move the top cover to achieve this<br/> then this gcode goes down 0.3mm and fixes the first layer absolute position<br/> When the printer will print it it will go to 0.1 (or 0.2) mm height, the pen will touch sligthly the paper and he ruber band will press it down gently.</p> <p>Now another important parameter is to tell the printer to retract 2mm in Z for "pen up". This is done into the Extruder Setting tab.</p> </li> </ul> </div></p></div></p> Category: 3D Printer Parts
