In order to make pcbs using tthe process of making pcbs with the Prusa PCB factory is based on etch resist pens.
1) Generate your design on the DesignSpark software ( i am using 7.2)
2) Export the design as an odb++ folder ( non compressed )
3) Copy the pcbfactory scripts into the generated folder and launch the scripts that will generate the 3D file, and necessary gcode files.
4) Print the pcb support . the pcb support is print at a specified location on your printer, and will ensure that the pcb is correctly positionned when you run the gcode files on the printer.
5) Calibrate the Tools : there is a specific point on the support ( named P0) . For each tool, you will need to move the head of the tool to that point, then enter the xyz coordinates into the associated config file.
6) install the pen tool on the printer, then launch the associated gcode files on the printer to draw directly on the pcb clad the circuit board with a etch resist pen
7) Etch the pcb using perchlorure or any other etching technique . there are enough tutorials on internet to perform this task, so i do not provide more information o this.
8) once etched, put the pcb on the support again, mount the drill tool, and launch the drill gcode, for each drill diameter. ( if your design uses 2 diameters, there will be 2 gcode files generated. you need to change the carbid, then launch the gcode file for the correct diameter.)
9) you can also paly with the solder paste "stencil" : this is a pla printed stencil that will probably need to be redrilled manually to work. But it can be interesting to play with. I will work at solder pasteprinting a bit later... ( i did some proof of concept, but i do not have yet the correct stl files to build something effective... )
10) you can use the generated Jig file to help you solder the pass through componentes : the Jig file allows you to print a suppoort that takes into accoutn the height of the components, so that you can work on the back side of the pcb, without the components to fall down.
11) the mockup 3D files can help you verifying in advance if your pcbwill fit well into your design...
