Prerequisites

• [X] I have read FAQ
• [X] I have searched existing issues (including closed ones)
• [X] I use KiKit at least version 1.5.0 (older version are not supported)

KiKit version

1.5.1

KiCAD version

8.0.1

Operating system

MacOS 14.4

Description

Run Kikit to make panel from project.

Onu output is:

An error occurred: Unknown file type
No output files produced

When I look in the output folder, I see the following files:

     13 Mar 18 11:56 panel.kicad_dru
1969916 Mar 18 11:56 panel.kicad_pcb?
   1271 Mar 18 11:56 panel.kicad_prl
  20393 Mar 18 11:56 panel.kicad_pro

If I remove the ? from panel.kicad_pcb? then I can open it and it looks OK.

Steps to Reproduce

Here is the kaki JSON:

        "rows": 1,

}

I will need to redact the pubnew file before I can share it.

Please rerun it at least with --debug 'trace: true' (as requested in the issue template). If you want, you can share the files confidentially via e-mail.

I was getting an error that --debug was not a command option. I just realized that it doesn't work when using a json file for the configuration. adding the following gave me the output:

"debug": {
    "trace": true
}'

The results are:

An error occurred: Unknown file type

I am also seeing a couple other errors but I think they are "downstream" to this one and may go away one I have this issue sorted.

edit

On second, thought, the "other errors" may be relevant.

The board is circular (with a circular cutout in the middle). Where the mouse bits are placed, the "tight frame" is not closing the way it used to. There is also a rogue vertical line on the user drawings layer (the lower end of which is visible in the screen image). Here is an image:

DOH!

The issue was the bash file I was using was originally written from a windows machine and had a hidden LF at the end. I was running the bash file from a Mac. This is what the file name was displaying as panel.kicad_pcb?. The ? was an unprintable character in MacOS Finder.

Once I found that, the panelization completed without error. Additionally, the edge cut was done correctly and the rogue vertical line went away.
