Hotend Question
I recently had a fun adhesion problem that caused the PETG i was printing with to get jammed up into the print head. I had to work to get it all out and after i noticed that my hotend looks like the linked picture. My concern is not the goop, but the bit sticking out to the left of the brass tip. Is that normal, i don't recall it looking like that and in the store the non-high flow hotend doesn't look like that.
RE: Hotend Question
If you're referring to the cylinder sticking out of the bottom of the heat block, no, it's not supposed to look like that.
That metal cylinder is the heater for the heat block, which in turn melts the filament. Its bottom should be flush with the bottom of the heat block.
In its current position, you're wasting electricity because a third of the heater is just heating air, not filament.
Likely the set screws holding the heater loosened and let the heater slide down.
Best thing to do is remove the nozzle & heat block, loosen the set screws, reset the heater and possibly the thermistor, then re-tighten the set screws.

Thanks. I thought it looked weird. I guess it must have happened over time and was hidden by the sleeve.
