This thesis is all about the construction of a small drawing CNC machine. Key parts of this build consist of 2 old and scrap CD / DVD ROMs that were preferred for low cost reasons. For the movement of X and Y axes we chose the 2 step motors existing in the old CD / DVD ROMs, which covered the requirements of our construction. For the movement of the Z-axis we selected a servomotor. The controller of our construction consists of an Arduino UNO, a CNC shield V3 and two integrated A4988 for driving the stepper motors. The UGS communication software with the CNC is based on a free internet application without the need for any further intervention from us. Also, GRBL is the library we uploaded to Arduino so that it interpretate g code. Finally, the design tool is a 0.1 mm design marker and the design surface is a note paper of 25x25mm
