Greetings , I am new to milling pcb's. I am currently using PCBxpress to create the pcb layout, print the layout, export the layout as a .dxf file. The .dxf only exports the hole locations. Then I use TurboCad to redraw the traces. Then I use LazyCam to generate the G code.
What is Gerber file and is there any freeware that creates it?
