I want to mill my own boards an I never found a program to do the conversion to G-code so I am writing my own. I am converting Gerber files to a milling file and have no problem with one sided boards but for two sides I need to mach up the two files. I can not find in the Gerber files I generated any offset reference to the other side. At the moment the only thing I can think of is to set an offset on one side and remember to use the same offset on the second. An offset is needed because the Gerber files x an y positions are relative to where the board is drawn on the page and for milling I want to reference the lower left corner as 0,0 position; I can not even tell how big the board is from the Gerber file without drawing it and calculating minimum and maximum x and y.
Can someone tell me if I am missing something in the files or in how I save the files Thanks George
