Re: Net names starting with a slash

 

I believe it indicates that the signal is inverted.

You can start an unconnected track (i.e. no associated net, or no netlist) in the middle of nowhere, but you may not be able to connect it to anything. It depends on your router settings.

If you want to be able to connect anything to anything (at least initially):

  1. Route > Interactive router Settings...
  2. Mode: Highlight Collisions
  3. Options: Allow DRC violations. (You might also want to uncheck "Remove redundant tracks")

(You obviously shouldn't "Allow DRC Violations" normally, or at least without good reason.)

Also the rel org figurers keep things on track

I select the start point, hit space to zero the rel co-ords then place
the line with the cursor keys. You can use the values in the rel or-ords
to ensure that you are aligned with a side or corner.

Using Kicad 5.1.12

I use the "add graphic lines" tool.

Click at the start point, click once every corner and double click at the last (first) corner to close.

The result is one line between each 2 corners.


AFAIK it still works in Kicad 6. ?


Yes, it works. But it is clumsy, if you have to use a fine grid.

The rectangle tool being constraint to a quadrate looks like a bug in 6.0.6 to me.

Hi all,

simple question:
How can I define a rectangle for the edge cut?

With the rectangle tool I can draw quadrates by clicking at start and end point.
A rectangle is shown when I drag from the start point, but I can’t make it persistent (do I need to double click there? I tried.)
Using inspect with the measure tool on the quadrat does not allow me to change dimensions to a rectabgle.

This is 6.0.6 on macos 10.15.7

Re: [Newbie] No synchronization of layout with flat hierarchy

 

You need to use the 'Replicate Layout' plugin to duplicate a layout for identical hierarchical?sheets. You can layout just one copy, place the pivots for each other duplicate sheets then just use the plugin to duplicate?them.
You can get the plugin through the PCM, but anyway

There is no feature to keep them synchronised, honestly that isn't really that useful, it sounds like a fancy 'software inspired' feature but when you are designing production PCBs where every trace matters, having things change without you explicitly asking them to would be terrible. You can just rerun the plugin when you have updated the layout.?

If you were expecting it to behave like Eagle, it doesn't.

Hi all,

I’m doing my 1st KiCad project.

I created a simple parent sheet and a schematic of a circuit which should be repeated 10 times on the board.
Everything worked fine but it seems that I have to do the layout 10 times manually, which makes the hierarchical design useless.
Is there (in 6.0.5) any possibility to derive the other 9 layouts from the 1st one or even better to keep them synchronized?

I found this FAQ

where I read, this feature will be in 7.0 and the plugin, which did this job, does no longer work.

What is current best practice?

Hi Gene,

I suspect we knew each other back on the linux kernel mailing list
from 12+ years ago, and from the RadeonHD and linux-kernel mailing
lists. We both have distinctive names! I've never used Eagle myself,
just KiCad and found it to make designing and fabbing my own (simple)
boards quite nice. It's getting all the rest of the electronics and
interfacing with the outside world that is the tough part!

Good luck with your projects!

Do they have a datasheet with the footprint detail? It's easy to make
your own footprint in KiCad.
The base is 7mm square, with 6 "pins" but it is analog out so only uses 3
of the 4 corner pins. I have a 6040 mill, with a 24k rev spindle and
engraving bits, and can write gcode, so for a one off, thats likely what
I'll do. The biggest problem is the lack of flat on the 6040's extruded
bed. So a pcb holding pallate must first be made to establish a truely
flat place to hold the pcb. The artwork I do have from honeywell is
pretty, but contains no measurement data other than the footprint is 7mm
square. Even pin1 isn't obviously Id'd.

The other problem is parts availability for 603 family resistors and
capacitors. The usual suspects are out of stock re the capacitor
assortments.

So we'll muddle along with temporary compressor speed controls. I can do
them in the linuxcnc gui with pyvcp tools.

How big a pix (in kilobytes, base-64'd) can I post, my camera is quite hi
rez and its difficult to shrink what I get down to a submissable size
without jpeg artifacts being pretty obvious.

Thanks all.
