| Abstract: | The paper presents the control system of a numerical control laser carving machine, a monolithic machine is used as the main control chip of the slave microcomputer. The system uses FIFO to achieve the consecutive data transfers.A Motion control card based on the EPP parallel port using WDM device driver is developed.The problems caused by the not real time of Windows operating system are also discussed. |
