GenCAD-Export: Testers needed (was: PCBA-Export for Flying-Probe Testing: GenCAD export broken?)


Chris Fiege
 

Hi Everyone,
I am still looking into the issue with the GenCAD-Export described below.

I made some changes to the exported file and gave them to my manufacturer.
It seems like my changed fixed the problem with flipped pads on BOT-side parts.

Now I would like to bring this fix into KiCAD. But I neeed someone who can import GenCAD
to have more detailed tests on this issue.

Please let me know if you can import GenCAD and are willing to do some imports to improve
KiCAD.

Thank you,
Chris

Hi,
I am currently working with a manufacturer to fabricate a design. After soldering we want to add a flying-probe test to verify that all went well.

Working with other tools I had supplied the manufacturer with ODB++ -files. Since KiCad does not have an ODB++ -exporter (for reasons see [0]) we had a look on
other exports I can provide.

GenCAD looks like a good candidate: KiCad can export GenCAD and my manufacturer can import it into their magic flying-probe-tool.

But in KiCad 4.0.5 and in a (nearly) current nightly (32abc27) it seems the GenCAD-export is broken:
Pads of components on the BOT-side appear on the TOP-side in the flying-probe-tool. The rest of the component is imported correctly and drawn on the BOT-side.
TOP-side only components are not affected.

I found a bug [1] that describes this issue on launchpad. But it does not look like anyone is working on this issue.

How do you export data for Flying-Probe?
Do you have a work-around for the GenCAD issue?


Or is maybe anyone able to import GenCAD? I am not and thus I am not able to work on the issue in KiCAD.
If you are interested in trying to fix this issue I could try to work on the exporter and rely on you in validating.

Cheers,
Chris

Hi Chris,

May you explain how from KiCad (V5, V6 or V7) you generate GenCAD files, being also interested in Flying probe tester to analyse possibilities to use KiCad ECAD for PCB dedicated FPT complementary calibration tools.
