PCB Milling from Gerber files

Andrew -

I have tried this using DeskCNC - it will take Gerber & Excellon drill files and convert to G-code. You can download a time-limited version to evaluate.

Why is that, Tony? Just curious, it's something I may want to try some day.

Cheers Tim

There's a limit to how fine a width you can mill with a tungsten router cutter, allowing for rough edges etc, while the photo-etch system which most PCB houses use (including us) will get you down past 5thou if the front end plotting is done with a laser and you expose the master with a decent focussed light onto the photo-resist.

Even with screen-printed photo-resist you can get close, but you are restricted by the mesh of the screen.

Tony / Peter / Tim,

Thanks for the contributions - yes I suspect that I'll have to go down the optical route - or more probably see if I can find a company that can make them from my Gerber files - though I expect that's a very expensive option.

Considered Laser engraving Andrew? I don't know if it will work having never tried it on my Laser kit but could be worth looking at and is usually very inexpensive at most online traders.

ps:The stencil cutter worked out fantastic. thanks :)

If you have the Gerber files, you should have two:

The file extensions are variable between programmes, but you can normally work out which is what. Both are normally plain ASCII with the first having the tool sizes against a table of T0 to TX

Second is a mass of X-Y plots and vectors. I can send you a few examples if you want.

You'll also need a drill file unless you are going to do that yourself.

I've had some good results with them, but they aren't suitable for next day turnaround :-)

Matt,

Thanks for that pointer - it seems a very good contact - much appreciated

I have had a couple of jobs done by RAK in the uk.

For one-offs (single sided) I use a laser printer on to magazine paper, then iron on to the fr4 and etch... Geo

Most people are using

According to me, what you are offering is more private case than general solution. You know that it can be used only in case of usage of Eagle. Important issue is that there is no rubout (only insulation), no cloning and many other useful features are missing.

Works fine for me ... from EasyPC ... I've spent enough money on all these 'power tools' over the years. And even EasyPC is going down the same path so I'll be dumping that soon. OH for KiCAD supporting gcode output ;)

Does big ears, sproutie whiskers and bridge spring to mind ?

What's a rabbit got to do with a bridge ?

I think you misunderstood - a dental bridge, to support those big front teeth?

Hey, I resemble that remark :-)
