Extruder Heater not Heating at Expected Rate
I've gotten this error message 3 times in a row and I've noticed the temperature on the extruder seems to be struggling to remain consistent then often will plummet when it starts the prime blob. The furthest it got was about a minute into the first layer on the first of the 3. It started after a successful petg print that I tried to start again.
I checked and the thermistor and heater cartridge are still in place tightly. I haven't made any major changes.

Other details:
Happens before the part cooling fan turns on
Temperature will sometimes go well past the intended then drop rapidly
Never able to get further than about 10% of first layer.
Thermistor was going bad. Replaced it and it's working much better now.
