Drill file creation

Anonymous — Tue, 25 May 2021 11:12:25 GMT

Hello,

I am trying to create a drill file but the CAM jobs batch file i am using ( gerb274x-4layer.cam) only has the following files ( see picture attached) which doesn't have drill files. Can i use gerb274x-mill-drill.cam batch file for 4 layer board ( even though on the description it says "for 2 layer board").

Thank you.

Gerber is a photoplotter format. The drill file is an "Excellon" file, generated by the excellon cam job. On the older cam processor these were separate jobs and you just ran both. There may well be unified jobs on the new cam processor but you'll need one that has both four-layer and drill parts. That may involve editing one to include bits from another.

Yes, you may.

So I can run just excellon.cam file to get drill info. No need to look for one that is both 4 layer and has drill file info in it?

just running excellon.cam file will be suffice for getting drill info?

Thanks.

It should. I should state that I still use V7.7 which had the old cam processor, and the manufacturing data export is always a two-step affair - one Gerber step and one Excellon step. The Gerber job is chosen according to the board stack in use, while the Excellon is always the same job. I think the newer versions tried to clean this up to a single click (including an attempt at automatically choosing the right job) but as long as the file names don't clash (which they certainly shouldn't) then I don't see any reason the old approach wouldn't work.
