it is that I need to write a VB/VC program, let's say we have an interface, there is a button "browse", then a gcode file (.txt or .nc i think) is loaded into the controller, then I click "run", the controller will read the g-code file and move the motor according to what the g-code said.
eg. G00 G01 X0 Y0 Z10, my program should understand how to read G01 X0 Y0 Z10 and then to move the cutting plate (sorry it is a laser cutting system) from coordinate (0,0,0) to coordinate (0,0,10)
hope i illustrate it clear...really stuned by this project
