So I was playing around with kfx format plugin and found It seems to work best if I convert an epub format into the rb format, then selecting the rb format to kfx format, that seems to of gotten me past the converting bugs that happen when you try epub to kfx format, it keep crashing with the Conversion Errors, but when it took the rb format and converted it to epub in the process of outputting it to kfx format it seem to of gotten no conversion errors, at least that worked for one ebook so far, I hope that helps if some people keep getting Conversion Errors like me, I am just playing with the format of kfx format since its so new, it seem like an fun thing to try for ebooks on my kindle paperwhite 2 device, to see if they really look better than normal azw3 formats or not. I hope this information helps , it seems once you convert it to the rb format it removes any errors you may have with an epub to kfx format, again it seems to make the epub more compatible when first converting it to rb format from epub format, then selecting in calibre the rb format as the input then the kfx format as the output format under calibre again I hope this helps users who are having the problems with Conversion Errors from kfx format. I got some errors that the main page doesn't even show with epub format to kfx format, that's why I was trying to find an easy way to make most of my ebooks into kfx format it check it out in any case.

the only thing I need to work on is getting the thumbnail image showing up, and the font size correctly set in the kfx format since I need to set the font right under rb format , also I had to manually copy the kfx format to my kindle paperwrite 2 device, since the calibre cannot transfer both thumbnail image or kfx format to the device yet, I guess that because the format is too new, and they have not made an transfer mode yet for the ebooks, otherwise the ebook file seems to load fine under the device, I think the an extracting zip plugin for the thumbnail option I have yet to try the plugin yet, otherwise my method of converting the files seems to work.

I may of misunderstand the last post I thought it was an plugin for calibre but I think I was wrong, in any case, I have to try the python command manually or find another way to place the thumbnail under the device hard drive. like see if the thumbnails for mobi and azw3 work for the kfx format or not. I have to play around if it, in any case I hope calibre is updated at some point to support thumbnail and kfx format tranfering in the future versions of it.

so the extract_cover_thumbs modified for kfxmeta , I was not able to import the zip file I got an error when I tried I have to find the website again that had it and read more to see exactly what I did wrong, if anything, the ebook is easy to put on the device, I just have to figure out how to place the thumbnail image their for kfx format, otherwise it seems to work without an thumbnail, but I would prefer to be able to load one if I can figure it out, any help about the thumbnail, or when calibre be updated to transfer the kfx format and thumbnail for it too, also calibre has an plugin for x-ray files, but I don't think the new kfx format supports that feature as far as I can tell.
one last thing if I understand it right the thumbnail has something to do with its support of ASIN of the KFX file created when converted, I just have to make sure it matches the information under calibre, and see if it generates an thumbnail then or not, again I am new to the kfx format plugin under calibre. so I have to experiment and see if I can get the thumbnail to be included in the file or not.

to not get the error below when converting from epub format to RB format into kfx format, make sure your source from epub format to rb format, has under structure detection the box label insert metadata as page of start of book that feature needs to be uncheck at all times when going from epub format to rb format, also needs to be unchecked when converting from rb format to kfx format, otherwise you will get the error below, I was able to convert my ebook once I made sure that feature was not selected in calibre.
