Failed prints show as cancelled - no error logged.

[Hagar01]

I am using Klipper and Octoprint (I canned Mainsail and Moonraker, they didn't make the cut for my needs)

My print failed and all the log showed is - "Cancelled"

It would be good to show the last few g-codes and the printers response for maybe - up to the last 5 seconds (Configurable?)

I was 3 1/2 hours into an 8 hour print when the error occurred.
I had to have a window open at work to catch the error a second time.
By the time I got home the errors had vanished into the depths of time.

Having this in the log would be beneficial to diagnosing faults.

Thank you.
