Strange behaviour after clo9gged nozzle

So I had a bit of a clogged nozzle, managed to get it working after a cold pull.

While trying to print a test small benchy, it asked me to change filament twice, seemingly at random.

I was printing with a single material, single nozzle, so I have no clue on how that works.

Could it be the filament sensor? I don't think the filament sensor would ask to pull the current material and then after loading would ask if it changed color/material.

Re: Strange behaviour after clo9gged nozzle

The filament sensor is very susceptible to dirt & dust. You can clean it by removing the small cap at top left [Edit: Right] of the extruder and blasting it with compressed air. It also can easily be thrown off by shiny or translucent materials. There is a fix scheduled for the next firmware release that should help, and you can download and install the release candidate (RC) version now if you desire. Meanwhile, if cleaning doesn't help, it may be simplest to simply disable it via the LCD menu for the time being.

Re: Strange behaviour after clo9gged nozzle

maybe just turn off your filament sensor.

I have a Prusa,therefore I research.

It just clogged again 5 minutes after posting this

The Cold Pull I did previously didnt seem to have much effect.

Right now I'm trying to see how I can clean it properly.
