2. Increase the Chapter threshold from 6 to 19.

3. If it still shows the same error, tick the box on " Do not add detected chapters "

Some other problems may be fixed in the " Look and feel > Layout ". Tick " Linearize tables"

THANKS for the suggestions, tried all the steps none worked for me.
The book in question is Ulysses(Penguin, with an introduction by Declan Kiberd) if anybody has it he/she can try and post if they were successful in converting it.

Also, for the love of God, I cannot get the cover of Shoe Dog by Phil Knight to appear, only the generic thumbnail pops up every time, if someone has access to its epub version maybe give it a go if they can get the cover to appear on KFX version.

Edit: Somtime back @HowlerX suggested to delete thumbnails in internal memory of my Kindle. Tried that also, did not work.

Edit2: Got the covers, not perfect nonetheless a huge improvement.

It might be a problem with those specific images or it might be that all together the images result in a file that is too large to be read properly. You could try breaking up the book with the calibre editor to see if those images display properly when part of a smaller file.

Forgot to mention that once you delete the thumbnail of the book you should also remove the book from the Kindle and re-upload the book to the Kindle. Not necessarily in one step. Do one, unplug; then do the other. My best guess is that whatever file is pointing to the thumbnail in the GUI is corrupted/malformed and deleting the thumbnail and book and re-uploading forces that "pointer" file to refresh properly.

Hi!

You can verify that the ASIN is set correctly by selecting the book in calibre and looking at the book details panel (usually on the far right). There should be an "Amazon.com" entry in the "Ids:" section. Click on "Amazon.com" there and your browser will open to the associated web page. Verify that the browser shows the expected book and that it is a Kindle edition, not a print edition. Use "Edit Metadata" to fix the ASIN if not.

This really works, but only for Amazon.COM. If the translated version of the book is only available in amazon.com.<A COUNTRY>, you need to manually insert <A COUNTRY> in the URL.

Is there a way to automate this?

Thanks.
Regards.

Spoiler:

I found a way to work past this error.

ERROR: Tables with number of columns more than 8 and rows lesser than 65 are currently not supported.

1. After you click on convert, open the options for Table of Contents

2. Increase the Chapter threshold from 6 to 19.

3. If it still shows the same error, tick the box on " Do not add detected chapters "

Some other problems may be fixed in the " Look and feel > Layout ". Tick " Linearize tables"

One other error mentions Table of Contents not being within scope or something like that. For that you can tick " Force auto-generated TOC "

Calibre supports ASINs for country-specific Amazon stores by appending the country code to the identifier name when creating the "amazon" identifier. For example:

amazon:B0064CPN7I --> https://www.amazon.com/dp/B0064CPN7I
amazon_uk:B00BAJ6GL2 --> https://www.amazon.co.uk/dp/B00BAJ6GL2
amazon_de:B016PFA0YO --> https://www.amazon.de/dp/B016PFA0YO

Something must have changed. Cannot use the command line interface to invoke conversion anymore.

calibre-debug.exe: error: no such option: -a

Make sure that you use a double dash before arguments that apply to the plugin:

calibre-debug -r "KFX Output" -- -a B123456789 lorem.epub

I get this response with one book:

calibre, version 3.15.0
ERROR: KFX conversion failed: Cannot convert Dire quasi la stessa cosa
Conversion error: Kindle Previewer
error: Error(YJConvValidator):E120044: Table with more than 20000 characters are currently not supported.

I tried to create a new Table of content using Edit Book, with no success.
Converting with the option to linearise tables works.

Apart from the "table" of contents (toc), I cannot find any table in the book, so I wonder what table is it referring to? is it a formatting thing, invisible when reading the book?

"Table" refers to a <table> element within the HTML content of the book. As you suggest, it might not be visible as a traditional table, but used as a method for arranging content.

Sometimes the "display" element can be used to display an element/text as a table. Look for:

display: table
display: table-caption
display: table-column-group
display: table-header-group
display: table-footer-group
display: table-row-group
display: table-cell
display: table-column
display: table-row

in the CSS. Any of those won't work with Kindle Previewer.

Any reason why when i convert a EPUB to a KFX document (using latest calibre + output plugin) that I lose my book's cover (PW2)?

I even did the polish book first before transferring.

I assume that you are referring to the cover thumbnail shown in the library grid display rather than the cover shown as the first page of the book. If so then see the “Showing Cover Thumbnail Images on E-Ink Kindle Devices” section in the first post of this thread for solutions.

Hallo,

i was able to successfully convert an epub to kfx using the options above (Force TOC and linearize tables). The only thing did not convert correctly were tables (see attached images). The correct one is on Kobo Aura One using Kobo epub, the other one is KFX on Oasis 2. The AZW3 conversion is flawless regarding the tables. Increasing chapter limit did not make an effect on tables.

Are there any option to improve the conversion of tables for KFX?

thank you for your work

Support for HTML tables is limited in KFX format. I do not know of a work-around, other than using KF8 (azw3) instead.
