Loose Filament Tube
My new Mini+ has a problem. The upper end of the filament tube between the extruder and the sensor (pictured in red) is not properly retained; it keeps pulling out, especially during filament unloading. I see no obvious screw that could be tightened (unlike the sensor). How do I fix this issue?
Best Answer by JMH714:
There is - sort of. You need to loose the extruder and push the tube in and screw it back in. But this instruction from assembly Mini: https://help.prusa3d.com/guide/3-x-axis-extruder-assembly_199519 (step #45) should show you how to insert the tube properly.

Construction of this type (PC4 fittings) is likely to cause fewer problems (solved this way on my Mini): https://www.printables.com/de/model/358306-prusa-mini-extruder-rear-with-2-pc4-m10-connection

RE: Loose Filament Tube
Many thanks JMH714. Well hidden, no? Am I reading this correctly? The extruder is attached to the Z-carriage by only TWO screws (lower left and upper left [at the inspection door])...
RE: Loose Filament Tube
Many thanks @karl-herbert. Good point; the design could be improved. I'll print one of these if tightening does not correct the issue.
RE: Loose Filament Tube
Yes, it's "hidden" - but it's right inside the extruder - you need to remove the extruder body and screw it in from inside. See Step 47 - just unscrew those and you can see a screw on other side as picture shown in Step 45 and tighten it.
