Flashforge Dreamer (NX) - Solving Under-Extrusion Problems by Cleaning the Nozzle and Replacing Tube
In this video I diagnose why I've been having under-extrusion problems lately by disassembling the Nozzle and Heat Break Tube.
I also use a "cleaning" filament to help keep the nozzle clean especially when switching between PLA & PETG filaments.
Based on what I learned, I've decided to stick with the nominal temperature limit of the printer (240 degC max) even though you can set the temperature of the extruder higher (up to 248 degC).
I'm able to print PLA & PETG at 240 degC or less, so there's no reason to go higher even in a cold unheated garage.

I used NovaMaker cleaning filament, but it's not on Amazon right now. Here's another one that's probably just as good:
