This is the way. When I got an ACE I thought that I’d be doing multi-colured prints all the time. How wrong I was. The ability to automatically move to a new reel of filament when one runs out is a game-changer though.

There seems to be a few publishers missing here …

• Baen books (https://www.baen.com/) have never applied DRM to their books.
• TOR (https://torpublishinggroup.com/) stopped DRM on their books about ten years ago.

Baen typically sells their wares directly but TOR are through the usual sellers but have no DRM. I’m not sure how this works in practise with Amazon’s new “you can’t get the files” policy, but they are probably in cleartext somewhere.
