Hi all, I am new here and very much appreciating the Calibre app and the options that it represents,

My prime interest currently is to remove DRM protection on my numerous veterinary Kindle-texts so that I can save them effectively, but also to convert some of the larger ones (original Kindle azw3 file sizes of 20 to 40 MB) into pdf files that I can subsequently split into various chapters to ease their viewing and manipulation by my iPad iOS Kindle app,

I have so far successfully converted one text from AZW3 to PDF and thence using the Google Chrome print-to-pdf function, was able to save as chapters, so job done there very nicely.

However I have another identical format Kindle text, which is larger at 36 MB, and am experiencing the following when trying to convert it from AZW3 to PDF:

it starts normally, and then rapidly jumps from 1% completion through 35% and 40% completion to 47% completion, all within a minute or two, where it then stays for up to approx. 75 minutes of conversion time, at which point, in two successive tries, I have quit and shut the application down, assuming that it was stalled and wouldn't complete the conversion.

Am I wrong? Should I just leave the application running beyond one hour to allow it to finish? It certainly drives the processors a lot as the computer's fans are on full speed/time and this is a Lenovo P50 laptop workstation with Quad core Xeons and 16 GB RAM, so that seems odd.

If Calibre isn't able to complete a conversion to PDF, will it tell me at some point? It seems to me that it should at least move beyond 47% by one hour's time . . . No?

cheers, thanks, appreciate any help, is the file size simply too large? I doubt this,
