[kicad-users] Comparing gerber files for changes
Hi, I have two sets of gerber files that I THINK are identical. Any ideas how to be sure? I can load multiple gerbers into the viewer, but if I load layer1 from one set and layer 1 from the other, they both seem to be loaded the same colour, so it is impossible to tell if there is a difference. Any ideas? Cheers, Ben

Download Viewmate(free). Use the Import Gerber selection and you can set each layer to a different color. Dave - WB6DHW http://wb6dhw.com Thanks - In fact, I downloaded Viewmate, but then set all the layers to the same colour and told the program to XOR the layers. This was perfect, as everything vanished but the differences :-) Cheers, Ben
[kicad-users] WinEDA_DrillFrame::GenDrillMap() : Unexpected Draw Type
Hi - First off apologies for posting to users and developers - that was a mistake! I am getting the error listed in the subject line when I try to create a drill file for my board, however having said that the drill files do appear to be created succesfully. Does anyone know what this error means? Secondly, and less importantly, does anyone know how/if I can toggle which layers are visible (rather than just active) in the PCB editor to help avoid things getting jumbled? Cheers, Ben

Does anyone know what this error means? This is an internal problem, and i suppose this is only for the drill map.

So the drill file that is produced is OK, and is not affected by this error?
[kicad-users] Re: composite layers and negative plots
Ah, that makes sense. I tried producing gerbers with fill, no problem. Then I produced one with some altered pad shapes, and the commands in question appeared. I have emailed Olimex to ask them about this :-) Thanks for the afvice, Ben --- In kicad-users@yahoogroups.com, jean-pierre charras - INPG [EMAIL PROTECTED] wrote: barkerben a écrit : One more question (I have answered the above myself via experimentation). I got the following from Olimex, who I use to etch boards: Hi, Your gerbers contain composite layers and negative plots (G36 G37 commands). On such gerbers we can't do DRC check, panelization nor to ensure correct phototools plotting. Please ask your cad vendor how to generate your copper pour with stroke hatch filling instead composites and send your files again. Thanks G36 and G37 commands are *NOT* composite layers and negative plots. this a polygon fill command (start and end fill polygon), used to draw rectangular pads when the pad orientation is not 0, 90, 180 or 270 degrees (for instance 22.4 degrees) or trapezoidal pads. This command is a very common GERBER command...

[kicad-users] Three basic questions from a beginner...
Hello, Can anyone answer the following basic questions from a beginner (previously used Eagle): When going from schematic to PCB I need to choose the package for each component. The filtering option appears to have o effect - I always see all 356 packages for each component. Is there a reason for this? Also, since the package is not tied directly to the device as in Eagle, how do I map device pins to package pins? Is it just done in numerical order? Final question... keeping the PCB and the schematic in sync...if I route a board, but then go back and alter the schematic, do I have to start my routing etc from scratch or is there a way to just update what has changed? Cheers, Ben

One more question (I have answered the above myself via experimentation). I got the following from Olimex, who I use to etch boards: Hi, Your gerbers contain composite layers and negative plots (G36 G37 commands). On such gerbers we can't do DRC check, panelization nor to ensure correct phototools plotting. Please ask your cad vendor how to generate your copper pour with stroke hatch filling instead composites and send your files again. Thanks Can anyone answer his question? Cheers, Ben
[kicad-users] Re: composite layers and negative plots
I think the problem occurs when I pour copper areas: find out how to generate your copper pour with stroke hatch filling instead composites and send your files again When I do not pour, there are not G36 or G37 codes, when I do they appear.
