They Have A Ring About Them 103 Comments You put the batch and config file into the kicad project folder and drag’n drop the kicad project file onto the batch file and it automagically supplies all the file names, paths, etc. The finesse in using PCB2gcode comes not from the (very) outdated GUI, but from a premade config file and a windows batch file. Sadly it is the only part not buildable in Linux. To mill multiple projects at once the GerberPanelizer from ThisIsNotRocketScience is very usefull. Yes these holes need to be drilled a new every time. It supports double sided along a mirror axis – which means manually controll the machine to drill through the pcb into the support material (HDF) in at least 3 places symmetrically to the mirror axis and insert location pins in these places, so the pcb can be flipped in place after milling one side. Then use PCB2gcode to create movement files for the mill from said gerbers. The workflow I have figured out for me is Kicad for the PCB, export to gerber. Posted in how-to Tagged cam, CNC milling, EDA tools, Logic simulation, PCB home milling, spice simulation, vacuum tubes Post navigation Are you milling double-sided boards in your lab? If so, let us know about it in the comments below. Adapting this process to double-sided PCBs is doable, but more complex. They use wire links here and there to jump over traces. It seems that the bulk of ’s vacuum tube PCBs are single-sided, and reasonably so. If you’re planning to make home PCBs for a 273-pin PGA chip, this isn’t the technique for you. We should point out that is making boards mostly for vacuum tubes, where circuit trace width and spacing distances are generous. That said, these procedures should adapt well to other milling machines and engravers. First of all, a Bridgeport mill is a pretty good sized, and heavy, tool. We like his use of the machined pin socket inserts for building a vacuum tube socket directly into the board. Using this example, he proceeds to design, simulate, build and demonstrate a working circuit board. Momentary switches are used to generate the two addends. FlatCAM, a computer-aided PCB manufacturing toolįor this video, makes a half-adder circuit out of four vacuum tubes plus a seven-segment VFD tube to show the combined sum and carry outputs.DesignSpark PCB for schematic entry and PCB layout.TINA-TI, Texas Instrument’s version of the TINA SPICE simulator.He points out that these are the tools he uses, but the overall process should be similar no matter what tools you use. In a recent video, walks us through the steps of making a sample PCB, introducing the various tools and procedures of his workflow. If you keep up with various retro vacuum tube projects, you probably have run across aka ’s various PCBs that he makes on his own Bridgeport EZ-Track 3-axis milling machine - massively oversized for the job, as he puts it.
