Hi all, as I was unloading filament the small PTFE tube on the filament sensor simply came off with the filament.

I contacted support and they just told me to jam it back in. I did and it seems to be working fine now.

 

Putting this here in case someone else get the same issue, and to hear if you guys have any thoughts or tips on how to stop it from happening again.

Mine came off and I lost it.  I replaced it with a longer version.

It depends on how much work you want to invest. I have printed a new case with a PC4-M8 fitting. Actually I have rebuilt the complete extruder which already contains the sensor with controll LED.

That looks like this in principle:

As far as I know, Prusa provides CAD data, so it is easy to integrate a PC4 fitting into the case and reprint.

I think this is a small weakness and if people are interested, I will possibly rebuild the Prusa original PC4-M8 fairly and make the data available.

I have just implemented this (PC4-M8). Would someone test this?

I quickly redesigned it and of course I didn't test it on my Mini, because I already used a different solution.
But I would be glad about a feedback and possible suggestions for changes.

Thanks for all the answers 🙂

I'll keep mine as is for now, but if it continues to act up I'll test this mod for sure.
