V8 PCB Routing Tool -- Switching Layers and Layer Numbering [message #168922] Wed, 25 January 2017 00:06 Go to next message

OK, so this is the result of someone at Autodesk not really understanding how EAGLE really works....

The new routing tool has some use. Backspace to delete the last segment of manually routed trace is great (something Altium has had and I missed when in EAGLE).

And being able to use the space bar to switch layers, instead of the middle-mouse button (which still works), is really handy when there are only 2 routing layers.

BUT....

I loaded in a 2-layer board from an older version and started randomly ripping up and routing with EAGLE v8 Free version. I couldn't figure out why it kept complaining about trying to put traces on the bottom layer, complaining that I was exceeding the license limits.

I think figured it out: When it tries to switch layers from top to bottom it changes to Layer 2! It should be changing to Layer 16 which is always the bottom. Trying to change layers to 16 while the routing tool is active won't work.

If I stop routing and explicitly change layer to 16 with command line, then I can route on the bottom layer. So good idea, just didn't quite get it nailed.

For bonus points, check out suggestion about setting active routing layers which would help even more.

Cheers,

James.

Hi James,

I can't reproduce this. If open hexapod and do the same thing it
switches to the only other available layer.

Could you confirm your DRC settings? You are super experienced user and
I'm sure you wouldn't miss something so obvious but we are human after all.

Best Regards,
Jorge Garcia

Jorge,

Yes, the drc layer settings are (1*16). I played with (1+16) just in case, but no difference.

It was a design that was originally in v4.1. So I tried another from V6. Same thing. This board had multiple layers. But when I tried to swap layers it would only use layer 2 and no other layers. Layer setting here is (1+2*15+16). I don't get a selection menu of destination layer either, it just always goes to layer 2.

I'm on a Mac if that matters. Basically, it looks to me like the freeware license will only swap between layers 1 and 2.

James.

Hi Jorge,

hm.. I'm also testing the version 8 in free version.
-> I have a similar problem:
Just for try and error::: example, an old 5 layer PCB, larger then 80cm², there i can routing (manually) just on the top layer.
DRC: (1*2*3*15*16)
I thought i can routing on the top also on the bottom layers.
Im working with Windows 10Pro.

Best Regards,
Gerald

Hi Guys,

I still can't reproduce any of this. Would someone be able to post a
screen capture showing what you guys are seeing(doing)? That would help
me figure out exactly what is going on.

Thanks guys.

Jorge Garcia

Attached is a screen shot showing that when it tries to switch layers it automatically selects layer 2. If I manually change layers to layer 16 then it will route as expected.

Hi James,

In your screenshot something else is going on. It looks like the trace
is over a dimension line. Since EAGLE changed to an area
limitation(even in the freeware, it's now 80cm^2) it's now using a
different mechanism to enforce the area limit. I wonder if there is an
interaction going on.

Would you be able to send me a sample file for review?

Best Regards,
Jorge Garcia

Hi,

attached the board.

This is an old PCB created with the V 5.12
Now i tried to test the router for routing and error messaging.
I can route the TOP layer across the board but i cannot route on the other layers.
/ oh, (just tested now before posting) i can also route the BOT layer across the board. ->The PCB is larger then 80x100mm.

Gerald

Hi Gerald,

Make sure the other layers are setup in the DRC and that the layer you
want to route to is active. If you use the spacebar (press mutliple
times to cycle through your layers) does it not cycle. The way you can
tell is by looking at the bottom of the screen it will tell you what
layer you are currently on.

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

Best Regards,
Jorge Garcia
