    Re: Which bits to use for PCB milling?

    Just thought I'd post here quickly on a success.

    I've recently had to go sub-200 micron detail in a circuit, where the spacing between component legs can be from 0.4mm to 0.8mm and the biggest...

    Re: Cutting and drilling PCB with 0.8mm end mill

    Was that with the 0.8mm?

    Thanks

    Re: Cutting and drilling PCB with 0.8mm end mill

    Thanks for the details - pretty close to what I do with a 1.8mm, although you're using a 2.4mm I think.

    Though the .8mm ( and especially the .4mm ) look so thin and fragile. It just seems that...

    Re: Cutting and drilling PCB with 0.8mm end mill

    I'd love to know this as well, especially using it to route out larger holes (eg, 1mm, 2mm, 5mm etc ) - And whether it can handle it in larger holes through the entire PCB or whether it needs to go...
  5. Is there any local compendium of experience?

    Hi All,

    Just new to the fun, had a non-functional CNC mill ( 6040 ) for about 15 years, of which for 14 years, 11 months it was a shelf ornament. Finally fixed it up and got it working under USB...
  6. Re: List of CAD Software Companies that are NOT subscript1on/cloud-only (or have plan

    How about CorelCAD.

    It's an Autocad clone, but it's getting pretty good for 3D stuff lately. I've been using it to design night vision equipment for about 8 years so far. The 2014 version is...

    Poll: Re: Have you finished a cnc machine?

    Just finished getting a working machine after 15 years ( is that a record or just par for the course? ) and cut out some PCBs which was the driving motivation for getting the machine running.

    Re: 3040T 4 Axis board

    From a quick google, I think the four axis board uses the same controller - eg;

    Do you mean the one in this article for the 3040T 4-axis version?...
  9. Re: Milling PCBs with free software... What's out at the moment?

    Thanks for the suggestions. Moving to GRBL probably wouldn't be ideal as I don't think my motion controller support it, but I'll take another look at KiCAD. I did check it out before, but gave up on...
  10. Re: Milling PCBs with free software... What's out at the moment?

    Oh wow, that works great, even given the application's limitations... I hadn't been able to work that one out even though it seems so obvious in hindsight, so thank you very much for pointing that...
  11. Milling PCBs with free software... What's out at the moment?

    Hi All,

    My first post here, and I'm new to both CNC and milling PCBs. And by new, I mean I had never even powered up a mill or milled anythingbefore three weeks ago and I'm still only...
