Extrusion aborted due to Cura temp changes

Posted · Extrusion aborted due to Cura temp changes

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?

 

Here is the generated G-code

    go to material and then click the up top left box ,and check those boxes  initial temp and so on. Then you have control over everything. Because the are occasions you need to tweak them. Ran into the same issue! I cannot take pics of this.if you check the boxes it will show the next time you on the the material settings menu

    You have at least two post processors running.  Did you print a temp tower recently?

    Cura does not directly add the lines in bold below.  They are from at least one post-processor.  Since the second M117 line immediately erases the first M117 from the LCD screen I'm guessing at least two post processors.  The temperature lines may be from a third and the fan line might be from a fourth.

    Are you using OctoPrint?
