Abstract

The purpose of this thesis was to build a plotter for printing vector graphics on paper. The plotter is computer controlled by a Mach3 program. Mach3 is a control software for CNC (Computer Numerical Control) machines. The components of the plotter software are Mach3 and a G code generating program. Mach3 has a large amount of functions because it is intended for CNC machines. However many of these functions are not needed for the plotter. Thus I have only focused on these aspects of control software which affect the plotter. The input of Mach3 is a G code program. That is why I made a program which transforms vector graphics into a G code. The thesis covers the hardware and software aspect of the plotter. It provides descriptions of designing and building the plotter and making electronic circuits, which are a link between the computer and the device. The focus is on the bipolar stepper motors which are the key part of this device. The electronic circuits transforms input signals into high current signals for driving motors. The plotter design and descriptions of axes mechanisms are also given in the thesis.
