Plotter using CD ROM parts

thingiverse

Toy designed to plot with, built to fit on my DIY CNC but suitable for other designs as well. Using the shafts and steppers from 2 CD/DVD ROMs. Now using it for scribing on copper clad too! Not for those who are faint of heart and will require a little tweaking to set the current and voltage to run properly. The motors can get slightly hot in cases where more torque is required. Gotten many hours of fun from it so far. Apply some wheel bearing grease to the screws but not the shafts! For the pen, used a Retro NEON GEL 0.7mm. You will need to modify it to take the pens you can find. For the pen, removed the spring from the bottom, cut it and inserted it on the other end to give the spring action on the tip that is required. There's a picture for the scribe assembly and if you modify that for a pen, the tip can be rigid. After printing, drill the shaft holes to final size. If you make them too tight, the motors will be too weak to move, and if they're too large, you'll get slop. Same goes for the scribe holder. Use 3x9mm self-tappers to mount the motors. For the scribe tool, cut a cheap PH2 screwdriver and sharpen it with a flat angle, not too pointy!

Yes, the toolpath is terrible - it's the Inkscape GCode plugin, not me!
