1/2 way through the print job Klipper shuts down with error "Heater extruder not heating at expected rate" and Klipper shuts down.

I am running Voron v2.4 printer with a E3D Revo Voron hotend printing with ABS filament on a Honeybadger plate.

Heating Bed at 110 Celsius and hotend is set to 230 Celsius

Part cooling is completely turned off
 
MAybe also a partially cracked connection or wire, which is closed at certain toolhead positions and opens at another.
 
Do you have a screenshot of the temperature graph?
Interesting, I didn't think of watching the graph. It does show just before it shuts down that the temp starts to drop. I'll have to put my voltmeter on a different points to see where it's failing. Thanks

Maybe also check the kliopper.log to check if the values got logged:

i.e.:

Found that the hotend temp sensor had a very intermittant connection at the hotend. Shutdown was due to the sensor dropping temp. Fixed it. Thanks for you help.
