Have a question about CadSoft EAGLE?  Ask our Expert, Jorge!

Hello Wayne,

I hope you're doing well. Without seeing gerbers it's hard to tell, but if I had to guess, you might have accidentally added the stopmask layer (tStop) to the copper layer gerber. The space between the mask openings is very small on this board and visually it might trick you into thinking that the pins are shorted into four groups.

If you wish you can send me the files for review to support@cadsoftusa.com.

Let me know if there's anything else I can do for you.

Best regards,

Jorge Garcia

Hello Jorge,

When I try to create gerbers from a board file for the Arduino Pro Mini reference file the pads for the SMT Atmel CPU are shorted together in 4 groups.

Also other shorts occur as it appears to be filling some of the gaps with copper. I am using the reference board file found at

https://www.arduino.cc/en/uploads/Main/arduino-pro-mini-reference-design.zip

What am I doing wrong?  I used the standard CAM Processor job file gerb274x.cam that is included with the freeware version.

Thanks,

Wayne

Hi Henry,

I hope you're doing well. The library receives it's name when you save it, so there isn't really a separate field for that. Components have value placeholders in the library >VALUE this place holder gets replaced by the actual value once you put the part in a design.

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

Hi Chris,

Just to clear this up, Rob Pearce was the one that responded. When we

respond from the forums element14 just shows users as Cadsoft Guest.

Thanks Rob.

Hi Jorge,

I have only just started using Eagle CAD so this question probably has

an easy answer. I have added an 74AC04N to my schematic but there are no

pins available for the ground and Vcc pins (pins 1 and 14). on error

checking, the software tells me that there is no supply connected. How

do I do this?

Kind regards

Chris

 

There are two possible methods:

1) use the default supply nets

The 74xx family uses VCC and GND for supply, so if you add supply

symbols for VCC and GND on the same schematic page, they will get

connected automatically.

2) use the seventh gate

The 74xx04 library device consists of six identical NOT gates, marked to

be added "NEXT", so that as you drop the gates you get six from one chip

then start a second. However, there is a seventh gate in the device,

which is the power pins, marked to be added on "REQUEST". The way you

get to this is to select the INVOKE tool and click on one of the gates.

Then you pick the power symbol and place that somewhere (coincident with

a get will usually line up neatly) and connect your supplies to that.

This is all covered in the tutorial and manual that come with Eagle.

Hi Jorge,

 

Is there a script with which the editors' windows size is configured

during eagle start-up?

 

Hi Odyskar,

I hope you're doing well. I'm afraid the there's no command I'm aware of

to setup the Windows size.

Let me know if there's anything else I can do for you.

Thanks!

Ok Lorenz, i am going to see this again..

Thanks to you!
