“Here I have one more mechanism for you i.e. CNC plotter from old CD rom. Hope you like it.
For making the movement of tool along vertical & horizontal path, the stepper motor movable platform is required. For the old cd rom stepper motors are used. Two stepper motor along with the platform are taken out from the cd roms. The platform is made using outer cover of the cd rom. The motors are mounted using nut & bolts. The stepper motors are mounted in such a way that they form a right angle which cause movement of one stepper motor in x- direction & other in Y- direction. The mounting is provided on X- direction moving motor for holding the tool i.e. pen for profile drawing & Cutter for cutting. All the Electronics parts along with connected wires are placed at backside. The movement of tool is done by programming which is explained in working.”
