Random filament unloads

Hello!

I just got my Prusa Mini+ and I love it.

But for some reason, it unloads filament mid print, and asks me to change filament.

What can be the reason for this?

I have the filament sensor, so it could be faulty, but I cant know, as the error message is simply "change filament" and the "messages" in the printer LCD do not display anything (it does not even post the message that filament was changed, nevermind the reason.

How can I track this fault down?

Not only is it slightly annoying, it also disturbs my prints, as I am printing with PETG and its not easy for me 🙁

Make sure you check the obvious: an inadvertently inserted filament change in PrusaSlicer.

Doh! There is such a thing? 🙁

Where can I find it?

After slicing a model in PS, go to the Preview. There's a horizontal and a vertical slider bar. When you click on the horizontal slider, a Plus sign will pop up where you clicked that you can use to insert a pause/filament change. They recently wrote a blog post with some good examples for what you can do with that: https://blog.prusa3d.com/practical-uses-of-color-change-in-prusaslicer_59563/

May not be the cause of your issue but I for one am certainly known for inadvertently inserting filament swaps…

Ah, thanks!

I might have inadvertently clicked that when I looked at the layering. I will look for that. Hopefully that was it
