Drill scale factor

[mrmjar...@gmail.com]

Hi

I am using DesignSpark PCB (from RS) along with CirqWizard. When I create my design files (gerber and excellon) from DesignSpark, and then import them into CirqWizard, the drill holes are 'out' by a factor of 10. This can be corrected by inputting a scale factor of 10 into DesignSpark, then it all works ok.
I am not seeing this error with the gerebers so don't believe that there is a scale problem with my designs.

I don't know whether this is a problem with the output from DesignSpark, or the input into Cirqwizard...

Any ideas?

Thanks

Mike

Hi Mike,

This sounds like number format issue with Excellon file. As there’s no decimal point in excellon format, so some assumption as to where the point is implied has to be made. By default Cirqwizard expects input in 2/4 (two integer places, four decimal) format. If I remember correctly, DesignSpark by default exports Excellons in 2/3 format, but this can be changed. So, the first thing to do is to check you have the same number formats both in DesignSpark and in Cirqwizard. In Criqwizard the format can be set in Settings -> Application. Don’t remember the place in DesignSpark, let me know if you can’t find it - I’ll have a look.

Regards,
Simon

Hi Simon

I've changed it in Cirqwizard. Not sure where to change it in DesignSpark... I'll let you know how I get on when I produce my next board. Thanks for your help.
BTW: The machine's running great, thanks. Really pleased with it.

Just to let you know, changing the format in Cirqwizard worked. I'm now producing boards with no problems. Thanks for your help.
