Hi guys, for my particular method of making up single-sided circuit boards, I like having the outlines of all the tracks on one layer, and tiny little squares wherever I plan to drill holes on another layer.
I can then combine those in my CAD software, and the engraver will make a centrepunch (almost) that greatly assists with drilling.
I'm dropping test pad 'components' where I want it to mark squares for me. But it's hard to delete these separately from my actual components, that go on the top of the board.
How can I make a library component that has an origin marker in the borigins layer?
Even when I have tried "mirroring" components to flip everything over, the origin crosshair is still in the "torigins" layer.
Any help appreciated, Matt
Edit: seems like what I've asked is impossible, since when you create components in the library, they are defined right-side-up by default, of course; the idea being you flip them over in the PCB as necessary.
My workaround is to make a tiny centrepunch shape on the bottom layer. I create one, then mirror it to make it on the top layer. Now I go Options > Assign "Ctrl + V > Paste", and I can duplicate them onto all my vias very readily. Now I just delete everything that's not in the top or bottom copper layers, and run the outlines_cstep.ulp routine for the tracks, then the same again for the centrepunches.

Torigins, borigins, shmorigins! The origin is on whichever side the component is on, as you found out.
If I were doing this, I guess I'd try to figure out some way of feeding the NC drill file that comes out of Eagle's CAM processor to the engraver, so that it made a little ding everywhere a hole should be in the finished board. If the engraver needs to be "printed" to by a Windows printer driver, I haven't a clue what to do

Wow matt, you are.. absolutely incredible... There's probably no such an advanced PCB engraving machine in my whole country.
Hi Firkragg, there probably aren't many such advanced PCB engraving machines in my whole country either, but I did this with a retrofixored CNC pulled from a technodumpster. Never mind that the only real way to get it to do anything is by typing HPGL straight down the parallel port... hehe

How did you just manage to scrape off the unwanted layer of copper?
With great care; it's a developed technique.

BTW, the board looks great, what is it?
Hi Steve, I tried all the permutations of ways of extracting drill code and gerber mess etc from Eagle... but the unfortunate bit is the last bit of CAD software I'm using to regenerate and plot-optimize all the artwork doesn't actually have any facility to create point entities! (Very frustrating!)

Can i order boards from you? LOL So now are you asking HOW to have the part on 1 side and the trace on the other or have them both on the same side? because I have NO idea what torigins and borigins, even are!
