How to pause a print to insert something in a cavity using Ultimaker Cura?

I have a model that contains a cavity, into which I want to insert a piece of metal, so I can use a magnet to stick to the print. How can I introduce a pause into the G-code without manipulating it manually in Ultimaker Cura?

Can I increase retraction length on an E3D v6 beyond 2 mm if I have a really long Bowden tube?

E3D mentions on their own wiki: Excessively long retractions will cause issues by dragging soft filament into cold areas. [...] for bowden systems you might want to go up to 2 mm. Retraction beyond 2 mm is likely to cause issues. I have retraction…

Avoiding stringing with flexible filament

I have some flexible PLA filament (https://www.amazon.com/dp/B00VKSSA4E/, presumably a mix of PLA with some platicizer) that's supposed to be easy to print with settings similar to regular PLA. I've seen recommendations to disable retraction, and…

False "Object does not fit into print volume" warning from OctoPrint

Octoprint warns me that the objects do not fit into the print volume. I noticed that this happens after a power-off cycle. Since I was overly anxious until today, I always uploaded the GCode file again and it didn't complain any more. Of course,…
