One thing to try: Make sure that your grid is set to 50 mils and then make sure that all the questionable items are set onto that grid.
Rest assured that your issue is not widespread; the vast majority of us are not fighting this issue (or any other particular ones that I can think of.)
Also…We are told on this forum that version 6.0 will be a stable release very soon, so it might help you to upgrade to that. It is presently listed under the “nightly builds.” Just install the latest nightly; I use the 64 bit “lite” version. Best to back up copy everything first as 6.0 files cannot be wound back to 5.1X
Showing 3 copies of J3 in your screenshot does not help much.
To me it looks as if some pins of J3 are connected to global labels, but those labels are not connected to anything else, and therefore KiCad assumes those pins are unconnected.
KiCad does depend on “perfect alignment” between attachment points of pins and labels with the endpoints of wires, and this is easiest to accomplish by working on a coarse grid as BobZ mentioned, but I think this is not the issue here.
You can verify if labels or schematic symbols are attached to wires by hovering over a label (or schematic symbol), then press g for drag, and move the mouse a bit. All attached wires move with the label (or schematic symbol). Then press Esc to cancel the drag, and the label (or symbol) goes back to it’s previous position.
Look at those coordinates in the ringed text. When I see something like 115.57, I know that you have been using something much finer than the default 50 grid.
There is almost no reason to change the default and I wish it was made much harder to do so.
I am thinking about proposing a wishlist item for dual grid in schematic, allowing a fine text grid, while keeping symbols almost locked solid at 50. Nudging text is the only valid use of a fine grid that I can think of.
Thanks. That seems to work. Is it switching or just disabling grids? Is it described somewhere in the menu or list of shortcuts? Those two keys are often used in this list…but I do not see what you say (even though it indeed works)
It is all somewhat confusing because CTRL+SHIFT also is used to de-select items from a group selection. I wish they were all documented in one place.
And in 6.0 I find that if I move too slowly, it will often move items that I do not want to move, without me pressing the M key.
I don’t know. Before first KiCad installation I have read all pdf-s (4.0.7, but they were not up-to date) and I didn’t know that until someone told me it here (I think it was in 2018). May be I just overlooked it somewhere because if you read about software you even didn’t tried to use you just don’t know what is important to remember.
@Piotr and @BobZ, there are two separate modifiers: Ctrl disables snapping to grid, and Shift disables snapping to other objects. Therefore holding Ctrl+Shift disables snapping to everything. It also won’t show up in the hotkey list if you search for Ctrl+Shift, but both should show up individually if you search or scroll to the bottom.
@dmetzler If you are still having this issue, it’d be helpful to upload your project. I know you’re a new user but perhaps a mod can bump you up a level, or you should be upgraded soon just by reading some other threads.
I have difficulty to remember some of these “keyboard shortcuts” (unsure if we are discussing a keyboard shortcut.) A big issue is different commands for different software. I am now in the habit of zooming in KiCad with F1 & F2. (My trackball has no scroll wheel and I am reasonably happy with F1 F2 zooming.) But then I will be running some other software and hit F1 which requests help.
HERE IS ANOTHER IDEA…IS IT FEASIBLE? How about when I select some text and hit the M key to move it, something pops up (visible but a little bit out of my way) to tell me about Shift, CTRL, or other available function modifiers?
Reading the forum continuously is a very good way to get skilled in using KiCad even not practicing it.
You never don’t know what you don’t know. You can find here answers to questions you even didn’t thought to ask. I don’t use KiCad frequently (last PCB I have finished 1.05.2021) but I read the forum to be be up to date.
