This program will convert any 1bit bitmap(a black and white bitmap) to gcode in a file txt ready to be used in any cnc program like Mach3. You can use this program to etch pcb board,etch an image with your cnc etc. The program will also give you a preview on the bitmap you convert so you are sure it's the right file. Can also generate the gcode in inches or mm,U can choose how deep the z-axis should be by setting the z depth and the size you bmp should be when etching with cnc. You can either select width and height from file,use 0.00026458333m per pixel or give custom width and height.
