Under extrusion issue i3 v2

Discussion

Hey all looking for any advice on how to fix this issue.

Running a Monoprice i3 v2 with MicroSwiss hotend.

Below is a picture of the under extrusion problem I'm facing...

Recently had a bunch of issues with my printer that forced me to replace my thermistor, hotend heater, and I also switched to PEI vs builttak. Now that everything is running again my old settings aren't really working for PLA.

​

It seems very strange that the skirt and first part of the prints seem to print perfect but then the it seems to trail off. Printer comes up to temperature no problem, I've tried back on painters tape/glue like I used to use, tried a few different pla's (all kept in bags) but not sure where to go next. Printing with .3 layer height, 60c bed, 210c extruder.

Clogged nozzle. Or maybe old filament that's gone bad. Or you have something wrong with your hotend heating circuit causing it to cool after printing for a short while. Good luck!

This could be caused by heat creep. Are you sure you put the hotend fan on the right way after you upgraded everything. I have seen people do that before.

Thought I might have found the issue when I took off the fan I noticed the extruder gears had lots of material on them. https://imgur.com/a/7HiKHX9

Fan was on correct and after cleaning the gears that didn't fix the issue. I guess next step is to take everything apart again.
