CNC mill for PCB building

Catwell
Catwell over 15 years ago

I have a CNC mill I would like to use in PCB building. What can I easily do with it right away?

 

I assume I can cut, etch, and even component place with it. Any one do something with a CNC mill in this vein?

    Hi Cabe,

     

    Hope you are doing well.

     

    If you use EAGLE, there are a few ULPs that will export your board files as G-code format, readily useable by most CNC machines. If you have a board design ready you can produce it in minutes with your CNC machine. The ULPs are:

     

    fastgcode.zip

    gcode-1.zip

    pcb-gcode-3.3.2.zip

     

    If you want to give a quick test download the freeware version from www.cadsoftusa.com, make a small board and export it to see how well your CNC machine works. If one of the ULPs doesn't work try another one, I've heard several customers use them with success.

     

    Check out this youtube video, that way you can see how the process works.

    I hope you have fun and that it works well.

     

    Best Regards,

    Hi,

     

    I'm currently using pcb-gcode with EAGLE for the G-code creation and then EMC2 running as the CNC controller.

     

    An early (low quality) test video can be found from here: http://www.youtube.com/watch?v=_xmdMWRpzmY

     

     

    Have you tried the other generators, and if you have, what are the advantages of them?

    Hi Elias,

     

    I haven't personally worked with a CNC machine. In doing support for Cadsoft a few customers have asked how they could interface their EAGLE board data to their CNC machines. I have pointed them to those ULPs and feedback has been positive that's why I recommended them to Cabe.

     

    Other users have mentioned that their machines can accept gerber files straight up, and they have also given positive feedback as to their experiences using their CNC machine. So that's another option you may want to look into.

     

    hth,

     

    Best Regards,

    Jorge Garcia

    Hi Jorge and thanks for the reply,

     

     

    I will take a look at the other ULPs most likely once I have my new workshop set-up so I can then report here a bit more of my experiences with other than pcb-gcode.

     

    With pcb-gcode there is no path optimization so by default there are a lot z-axis movement for the lifts.

     

    There is an optimizer that reduces the time significantly but the tool does not care about doing inside or outside first etc.

     

    Here is a forum thread to read more about the tool and for downloading it: http://pcbgcode.org/read.php?6,5,5 .
