Heat Creep?  

Fans not so much for ABS. The original heat break would have worked fine.

Can't speak to what you got - it's a franken-printer at this point.  That is definitely looking like you are printing too hot inside of an enclosure with the door closed.  What's your ambient?  (don't take it over 35 or so, is not needed).  That kind of under-extrusion can happen if the filament softens because it's environment is too hot, and the gears in the extruder try valiently to push soft plastic faster than the heat break can handle it.

Suggestion - go back to the original hot end setup with the nice PTFE tube.  It prints ABS just fine.  Also, look at how to dump heat from your enclosure.  If your hot end is making ABS soften, your extruder body is soon to follow, and you'll start seeing all kinds of strange unfixable problems (short of replacing the extruder plastic parts).  Remember, the parts in there are all PETG, so if you run too hot, you will end up with internal parts that no longer are fit to use as intended because they have bent.  The extruder idler is one of the first to go - so it may not be heat creep, it may be you have melted your extruder idler arm and the tension is now way off.

ABS cannot print at 180. That's PLA low temp temperature.

Perhaps some reading on how to print with ABS will be a good start.  Just trying to print at 180 can do what you are showing - it won't melt at that temperature, and the gears will grind up the filament inside the extruder.

RE: Heat Creep?

LOL 180 for PLA. Changed the heatbreak so I could print ABS, but I haven't yet 

Slice for a default PLA profile instead

In prusa slicer, try using the defaults.  180 is awfully cool for PLA.

RE: Heat Creep?

Sir, you're on to something. I reset the temperature to the default and it worked well past the previous failed point. I left for 30 minutes and came back to see it failing again. When I checked the temperature, it was 170/170. I definitely did not set 170 in my slicer and went to look and my gcode. No where did it say set temp to 170. What's going on?!

Any chance someone messing with you?

170 is a magic number, kind of.  It's the safety cutoff temp that the extruder will stop pushing filament. 

RE: Heat Creep?

I live alone so that's impossible. Something might be weird with the firmware because I have used both Cura and Prusaslicer to the same effect...

Check connections on the heater cartridge

I suppose it's possible that bad connections on the heater cartridge (on the Einsy board) could lead to losing nozzle temp.  When you redid your heat break, did you replace the cartridge?  How old is the printer ... could the wires in the loom be intermittent?

RE: Heat Creep?

Heater cartridge seems fine. What was weird was the set temperature was 170 when it failed and that was certainly not how I sliced it.

Just thinking out loud

A reflash might be worth trying.  Kind of like a mystery hammer though.

RE: Heat Creep?

Thanks for brainstorming with me. I recall before these issues I updated the firmware and used someone's gcode for automatic  temperature tower with int(z layer/8) function. That line must be stuck somewhere in the slicer or the firmware

RE: Heat Creep?

Yup, you found it. Thank you so very much for saving my sanity. Gosh I was pulling my hair out because of this.
