You might get away without them, but maybe not. ;) Sorry. OK, that shocked me, so don’t do it again, Up next, the ‘Ugly’ parts of ground fills, I think 0.9.9 also has some issue affecting selection of partially overlapping objects in the PCB editor that makes this very difficult - I worked around this ground fill issue by copy-pasting a ground fill segment from a different via/pad and manually aligning it with the affected via. But did you consider manually setting the routes to GND for the affected connections? and sensor do you want thin or thick connections): Add tests, so we can ensure the ground plane works in all applicable situations: This is already solved. I was only able to complete my project in 0.9.4. I think it is better to invest the time into make ground fills work reliably. I have a schematic view but it has not been organized at all. As a result, there’s a small chance that Fritzing generates gerbers that contain a single, board-shaped copper fill with no traces. So one could take image of the sketch and render it to a pixmap. A rats nest connection check. There is not one single point in the code that causes this. therefor use the option -p (panelize) or -pc (panelize custom) Learn more about Stack Overflow the company, and our products. This is a minor problem. I wish I spoke up about this sooner because the issue is very frustrating because so much time is spent making sure parts are actually grounded before the I send the files for production. Twice, the ground fill connectors were right where I wanted to place a via, making it hard to connect the two together. Why learn a. Here’s what I get when I do that on my current project: But this is all the further I have gotten on this project so far… Unfortunately, those side effects are not rare, and we already had to revert fixes. From irasc...@gmail.com on February 07, 2009 15:33:00. Then (conceptually) invert the image, and for each blob in the image, find the border Fritzing says it is OK, so after checking that the parts fit on to a printout of the board, I will send it to Aisler for fabrication. I have been thinking this thru, and thru, and thru…. Movie with a scene where a robot hunter (I think) tells another person during dinner that you can recognize a cyborg by the creases in their fingers. I guess the ground plane would be the shape of the board minus the modified exportDIY I had to fool it by drawing the new trace on the other side and then swapping it back. Is this correct? … . I accept that, I am creating ECU's for cars. That fix should not be to difficult. The fab uses this layer to mill out your board, so extra symbols can sometimes end up as cuts through your board. I thought why not fill it.I seem to recall doing some reading on Ground Fill. I'll have a second look at 2) now. i'm unable to build with this commit. We’ll occasionally send you account related emails. Ground fill does not (always) connect vias to ground planes, Pad is not fully connected to ground fill, Ground Routing (ratsnest should be removed), Copper fill is not complet in combination with curved traces, Setting a pin as a ground seed in pcb adds the connection to the ground fill but not the ground net. An Introduction to Circuit Design With Fritzing | Custom Working from the image makes analysis of the nets guesswork. 1 atmega328+ all necessary 'equipment' . I've just run into this today upgrading from 0.9.4 to 0.9.8 – I've got pins that are completely absent a ground. There are only so many ways to ‘tag’ things. For this exercise, I have joined the pads without using the ground plane. Well, I worked on this some more, and it has been an experience. We’ll occasionally send you account related emails. Of course this needs an explanation. your changes working like charm ;) except for the drill file. Ok, I think I'm done with this wave of changes, could you try again please? left should be traces, vias, and the ground plane(s). Why are mountain bike tires rated for so much lower pressure than road bikes? He has since switched to kicad. For example, if only the bottom side of the board is editable, the fill will only be created on the bottom side. Until then entirely disable to ground plane (only allow copper planes) feature to avoid users running into this open knife? A red connector is not connected. yesterday i give it another try. . SVG Tiny has some simple compositing, but what we need is shape subtraction, which The 3rd one is connected to ground by the wire I routed, like ‘c’ and ‘d’ above. @DetonationEMS Would you be able to share such a complex circuit? first of all you need a folder structure like: I should probably write a tutorial on the subject and post it up for others, but right now, I don’t have the time. fritzing ground plane; March 25, 2023 ; fritzing ground planecarbquik irish soda bread. Since fritzing is more focused towards breadboards and breakout boards, this isn’t much of an issue. We recommend checking your settings by clicking on Custom. If it's a technically challenging fix, perhaps a technical explanation here might attract some development help. Suggestions cannot be applied on multi-line comments. On the other hand, it makes them more difficult to understand for newbies. this is your working directory. But Most breakout boards I work with have ground planes, so does a pcb for breakout boards need a ground plane? All the vias are set to ground. Try to route everything on the top side, and only use the bottom for short jumpers to get around crossovers on the top. In order to KISS (Keep It Simple, Stupid) this I’ve decided to focus on just one small area. Maybe i am missing something? could we modify the svg output from exportDIY by doing the same widen and fill? I hope it's fixed, I found another instance of the same notation. Tap anywhere on the blank PCB and then change the shape to Arduino Shield (Figure 1) in the properties shape field on the . Forgot the part about the board layout. I cannot believe it's been an issue that's spanning years. Connect and share knowledge within a single location that is structured and easy to search. You can see there are no ground connections were there is plenty of room to have them. Common names are gerber, plot, and fab. 1. Also works with just three diodes, not related to label or ground fill seed. Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. And it is amazing how fast I need SMD components instead of breakout boards. Contact me directly if we can mention your contribution in a special way. I guess keeping posted when the issue is fixed and I'll try and reground what I know has caused issues in the past and we'll see what happens. Probably not. Take this example: The big green circles are the connections to the ground fill. is that correct? Yes, I deleted this file, I might have missed a reference, I'm re-checking for dangling references, it might take a couple hours because of the build time. Copper fill is not connected to anything, it's just copper area that isn't removed during pcb manufacture. but some things are connected as well. The most important thing is to make sure you’ve created a watertight board outline that meets our rules on the board outline page. Visually the ratsnest line on the middle-left of the uploaded image is such a case. If you’ve added a ground plane to your design and then move components or add traces, then any fabrication outputs will be incorrect, and your board will not work. I'm most concerned in how the GND fill works so I can connect my ICs GND together with VIAs, I would recommend against using fritzing. However, that could be through an internal connection in the part (a bus). I'm not sure I entirely understand the ground fill as it leaves spacing around traces and leaves them disconnected. If we encounter what appears to be an advanced extraterrestrial technological device, would the claim that it was designed be falsifiable? (i for inscribe) but bug number 2) seems to fixed as well. We have two parts that have a GND connector: Due to the bug #3794 (the issue we are talking about), the parts GND is not connected to the ground fill: After pressing the "autoroute" button, the parts GND connectors are routed. Measure the voltage between E+ and E- (power/gnd to the load cell). Did you make a schematic? SVG does have some compositing stuff built in. If a massive trace can fit through the space between the next part then why cant the part be connected to ground?? Sign in I didn’t really look too closely at the islands inside the yellow rectangle, because I noticed another problem with the one marked ‘c’. Each time a digital IC switches state, it draws a really short pulse of current. If your design uses ground planes, always update them before generating fabrication outputs. There is no reason for a ground connection to be missing here. What steps will reproduce the problem? When the file is ground filled with Version 0.9.4 (CD-498-0-a1ffcea 2019-12-01) 64 [Qt 5.12.3] it will work as I had it set for production. Connecting them would require something like a via, or a jumper. r3100 . So adding in ground fills is like icing on the cake…. The text was updated successfully, but these errors were encountered: From irasc...@gmail.com on June 17, 2012 00:22:52, also add bells and whistles so user will understand where the point is. That can chop your ground plane into little, unconnected pieces. Ground fill does not (always) connect vias to ground planes #2095 - GitHub to your account. I use GerbView, which is the gerber viewer from kicad. fritzing ground plane. The red dot marked ‘b’ is an island that is connected to the GND net through the via right next to it. By clicking “Sign up for GitHub”, you agree to our terms of service and Define ‘keep out’ areas as needed. I did search the forum and found some useful info. I was unable to even ground my existing project so I was unable to use 0.9.6 at all. So in 0.9.4 I was able to wiggle my was through the grounding issues but 0.9.6 renders the board completely unusable. gerbv from the geda project is what I use on Windows, but there are lots of others. The traces on the board did not connect to it, so the fill did not include it either. Set the Fritzing grid spacing to this value by going to View > Set Grid Size. privacy statement. The red dot marked ‘a’ appears to be a connection to the ground fill for everything outside of the yellow rectangle. Will this affect the PCB when I send it to Aisler for fabrication? and the edges are really smooth. Usually, the ‘not really connected’ traces will cause DRC errors, because Fritzing thinks they are part of a separate net, but are too close together. everything works. Some custom parts work with ground fills, and some don’t. It can be reproduced as shown above with any grounded parts or pad. Suggestions cannot be applied while the pull request is closed. That’s why I mentioned vanepp, is it something about the parts that is causing the ground plane to not connect to them? It does not connect to any connectors that I can see. The wiring was done in the breadboard view. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. here are new gerber and svg data together with the fzz. I have to shuffle parts/traces around of get what feels like nothing more than luck to get parts to ground. By clicking “Sign up for GitHub”, you agree to our terms of service and I think a big part of my issue was making an extremely complex PCB and it's not what fritzing is yet meant for. fritzing ground plane MonEnergy Consult LLC . put the fzz's in a subfolder of the "orders" folder. Check mark the connection you want to use. I wish you the best of luck and I'll keep an eye on future releases. Any pin that connects to ground would automatically be connected to the ground plane - provided that you manage to define the copper area as a ground plane. I am using Fritzing to create my first pcb, worked around 50 hours on this and i really want to send it already! You must change the existing code in this line in order to create a valid suggestion. My understanding is that light polarity punches a hole into everything that is dark polarity. After a while of playing around I found that the distance between the nearby parts and traces make a major difference. I am asking because a possible fix could still cause the same problem for your use case then. about it. packages call them "orphans" and it's usually desirable to keep them to cut down on The whole island that “C” points to is isolated in that image. Drawing a trace wire from a connector to the ground plane, the trace wire is If it's not, then it's another bug that needs to be addressed. SVG doesn't have. One problem with the workaround is that the GND plane only has one single connector, which could be hard to find a route to: If there was a single reason, we would probably already have fixed it, so this is a bit lengthy: After some 'simple' patches had to be reverted, I think the issue needs a bigger approach to tackle. i'm unsure if the cursor-bug comes from qt5.4.1 or your changes. We breadboarded the entire circuit and copied the design over to fritzing and I worked on putting the PCB design together (shown below,) however, I had a few questions about connecting all my grounds. @gmail.com on July 29, 2012 14:20:58. @jonathanhogg The example you uploaded is straightforward to show the bug, but it doesn't show why the workaround is impractical. @el-j , can you test this on the panelizer process? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Any thoughts on this? So this is confusing…. I gave up on expecting the ground fill to work as expected and manually traced all of my grounds before doing the fill. Last time we tried this it was too buggy, but I think the groundplane code is a lot more stable these days. Reusing heatsink vias for ground plane connection. Maybe a note about adding the copper plane? This is done by going to Routing > Ground Fill and selecting the same options you’ve used originally. I see when exporting to PDF that they are connected with "black" as being copper.. I had several projects with well over 100 parts on a board. I think I found an improvement to the generated gerber so that it is more compatible (I tested with 3 readers). I was also wondering how bad are copper "islands".. i have some places in Fritzing where the islands are red, these of course seem just like all the other copper when exporting to pdf for . to your account, From irasc...@gmail.com on August 24, 2009 06:47:24. Usually those are small enough to make adding a connector ‘awkward’. However, unsupported slots can be drawn on the board outline, using the same callouts documented forEagle Cutouts page. About big polygons that aren't connected to ground (or any other net); some EDA This is quite complex, and i understand that it will easily take many hours on a bigger circuit. flood fill that halts itself after a few steps of growth). and IT WORKS. If I run a wire from ‘a’ to ‘b’, both of those connectors turn green. The other one with 4 pins is a custom part (downloaded from the forum) and it’s connected correctly. Is it possible to have a copper fill area on both sides of the pcb? there are two more optional options: -nm (no message) and -drc (for an automatic drc check of the boards). I tried to included pictures. Two of them are 0.45 mm/0.45 mm, one is 1.31 mm/1.31 mm. Do you have an example for this? fritzing ground plane - pearsonairporttaxiservices.com However, Qt has QPainterPath::Subtracted(), so one approach would Since ground fills are absolutely recommended practice for PCBs and they are so clearly broken in the recent versions of Fritzing on standard parts (pin headers, regulators, etc. monkLights.fzz (23.2 KB). I don't think what I did was wrong before, but I can see why other implementation might have missed a detail. problem right now is that the terminal point of the groundplane connector is its This worked well for that case…. I think the 2) was there before, when we load fzz files, "sometimes" they are messed up. Large via : When the via size is strictly larger than 1.3 mm/1.3mm, then a copper blocker next to the via will not prevent the connection of the via to the ground plane (through the copper blocker). All the traces with a gray outline are not ground traces, the ones without a gray outline are the ground traces. I want to reiterate this is an issue with all versions of Fritzing i have been using for many years.. Have a question about this project? I created a gerber parser from this specification, and I can see the file fine in it too, so I might have a "personal" misunderstanding of the polarity system, and made the same mistake twice (in my parser, and in the Fritzing generator). center, which means that you can easily short your circuit as the wire jumps from I hope you accept this PR, because it tremendously improves the quality of the output. I am working with a product that has been designed, prototyped and finalized in 0.9.4. Ill highlight and point out what i mean in a follow up post. I was having so many issue and 2 years of headache with tracing, lack of parts and grounding I gave up. Figure 1. hej nraynaud. I really hope Fritzing can fix this massive issue. what is caroline rhea doing now / who is responsible for easement maintenance in georgia / fritzing ground plane. From jerome.b. Everything with an arrow is not grounded. However, attempting to select the ground fill segment from "under" any component outline was VERY fiddly, and once the ground fill segment was in place and de-selected, it was more or less impossible to move. C2 and C3 can be selected. anchored to the ground plane at the nearest ground plane border to the connector, and So . after the last commit the dependent file svg2gerber.cpp was deleted. So it is possible to drag a wire As shown in my picture above it was the only way I was able to ground the regular. and move it on an e.g. i'm not sure what is easier. be to try converting the SVGs to QPainterPaths (which have ellipses, rects, lines, have a good trip. Is there an issue for tracking the lack of ratsnest connection check support for ground fills, that together with a fix for this issue would make the manual routing of ground traces unnecessary? Indeed, ground fill seeds are not added to the ratsnest. There I could select C1 and change it’s values, but C3 couldn’t be selected and came back as a copper blocker. privacy statement. Fritzing's copper pours are only updated when you add them. A popup window will open and you can select what nets you want the fill to be connected to. So I switched to schematic view to correct the value. Shortest leads possible, shortest traces possible. There is no clipping in the panelizer, because it calls back everything one layer at a time, so when I receive the order to generate the drill file, I don't have the information about the PCB shape (ditto for the silkscreen/soldermask clipping).
