3D printer to 2D sketcher for Ormerod

thingiverse

Turn your 3d printer in a beautiful 2d sketcher. With this support you can draw with pen or pencil (not recomended) on sheet in a very precise way! I hope you like Instructions What do you need: 2x M3 nut 1x M4x20 screw with flat head 1x M4 wing nut In order to do correct gcode to draw, instead print in 3d, I perform these steps: 1) Select the silhouette I'm interested in and import it in Illustrator 2) Auto tracing the edge and export in DWG ALTERNATIVE: could be to do this step manually, tracing the contours in autocad or in a vector software you like/have. 3) Import in solidworks DWG and set a very thin thickness (< 0.2mm) and export the STL ALTERNATIVE: you can do this directly in autocad 4) import STL in slic3r (i'm using slic3r but you can do in the software you like) taking care of the following settings: Set a Z lift of 1.5mm at least Set nozzle diameter to 0.2mm (this improve accuracy) Disable top/bottom solid layers Set the layer height to 0.2mm (equal to nozzle diam.) Set seam position to "nearest" Best and beautiful infill is IMHO rectilinear, the percentage is of your choice. Do some tests ;) Set at the end of Gcode a lift >2mm (G91 ; G1 Z3 ;) before any movement Speeds are the same for infill and perimeters (i'm using 40mm/s) Disable skirts Use low temperature (i'm using 40°C) just to deceive printer, because you cannot unplug the entire block of extrusion and its sensors, not worth the operation of the printer. 5) Place on the printing bed a thick sheet, latex or a dozen stacked sheets, and above the sheet you want to use to "draw" 6) Make sure to REMOVE filament from extruder and feeder 7) Set the Z zero point 0.8mm - 1mm below the shet level. More than this height will be high, more the trait will be pronounced 8) PRINT! I don't suggest to use pencil because because in some decimetre the tip is consumed. If the pen doesn't write, before printing it is best to rub a piece of paper under the tip to spin the ball and get out the ink. There're two STLs, one is for hexagonal staedler pen/pencil and the other one is for nibs or round pen. ENJOY!
