Hi Liang,
The LSET object is merely where it's possible to add new layers but
doing so will not be helpful and possibly harmful if you don't
understand how layers work internally. Virtually every object on boards
and footprints has to understand what the layers mean in order for them
to work properly and the tools used to create and edit them. This
doesn't include all of the DRC and UI changes that would have to be
updated for the layer changes. I don't see this feature request being
done by anyone without years of experience with the KiCad code base. It
is a major undertaking. It's on the development team's list of new
features but it's not one that is requested very often (there are just
not that many users that require more than 32 copper layers) so it may
not make it into version 8.
Cheers,
Wayne

Hi Stefan,
Thanks for your reply.
Our products are for chip tests.
I already know the limitation for KiCAD and this ticket.
I want to know if I try to add more layer support in KiCAD, which part
of the source code should I pay attention to? bitset for LSET?
SIncerely
Liang

Hi Liang,
There is already a wishlist's gitlab ticket for this
https://gitlab.com/kicad/code/kicad/-/issues/7232
You might give a thumbs up there ;-)
And BTW. 50 copper layer, really?
I am curious what are you designing?
As you can see here
https://docs.kicad.org/7.0/en/pcbnew/pcbnew.html#capabilities
> KiCad is capable of creating printed circuit boards with up to
32 copper layers,

adhesive, solder paste, etc), and 13 general-purpose drawing layers.
So when you don't need 50 copper layer, there might be already
enough layers ;-)
Best regards,
Stefan

Hi Dear KiCAD Group,
We want to use KiCAD for our products, but we found one
limitation which block us.
The max copper layer is 32 now. but our products need more
than 50 layers.
I searched the group, there are not related information, so I
start this conversation.
I have two questions?
1. Why there is only 32 layers in KiCAD?
2. If we want to adapt the code of KiCAD to support more
higher layer,
Is it possible?
Which point we should take care?
Sincerely
Liang
