I have been going crazy trying to work out why my prints abort some way through. Turns out that Cura generated G-code is changing the extruder temp, up intiially then progrsssively down until the extruder is too cold, and then Octoprint aborts the print becuase of a cold extrusion error. My temp setting for the print was 200C - however I noticed that after a while the temp was bumped to 220C When I go look at the G-coide, I see the temp increased on an M104, then progressively dropped to 165 at which point extrusion is aborted (abouit 12 hours into the print in the last case) I am running Cura 5.2.1 Could I get an explanation please and a fix?
