I’ve designed a little pen-plotter with the goal to create a plotter that consist mostly of 3d-printed parts, is cheap to build and foldable for storage. The plotsize is about 12cm x 12 cm See it in action! https://www.youtube.com/watch?v=5mOlq3Rv6C0 https://www.youtube.com/watch?v=_qfLxyJa-bA https://www.thingiverse.com/thing:4645955/files Print instructionsBill of materials; 1x arduino nano 1x expansion board 3x Motor 28byj48 3x Motor Drive Uln2003 Driver Board 1x 5V power supply (any phone charger) 10x 100mm AWG wire 6x M2.5 x 8mm Screws (from old dvd drive) 8x M3 x 6mm (to mount electronics) 4x M3 x 12mm (to mount electronic lid) 1x M3 x 16mm 4x M3 Nut 1x Glue 2x M4 Nut 2x M4 x 12mm crossheads 1x 608-2RS (skateboard bearing) Step 1; Print all the parts with a layer height of 0.2mm When printing the lockring, pause the print to insert the M4 nut Push M3 nuts into the slots of the electronic case lid Use the lock ring to pull an M4 x 12 crosshead through the Y-axis. Step 2; Extend the motor cables of two motors (Z and X-axis) by about 100mm and tape the wire to a small bundle. Step 3; Assemble the plotter like on the photos. Use grease or chain-oil when assembling the axis and the gears for a smoother result. Slide them up and down a few times until they slide smoothly. (check if none of the corners came loose while printing, This will result in a slightly curved rail and won't slide) Before tightening the motors, push the up towards the slides to minimize play. Step 4; Mount the electronics to the board using M3 x 6mm bolts and wire up as shown in the diagram. Step 5; Glue the electronic housing to the plotter. Step 6; Upload the Sketch to the Arduino https://github.com/TGit-Tech/GRBL-28byj-48 Step 7; Download universal g-code sender https://winder.github.io/ugs_website/download/ Step 8; Create some drawings - https://cncphilosophy.com/inkscape-g-code-tutorial/ Or download mine Have fun!!
