And what I do when the ball freezes. I hope for a permanent solution

When that happens to me, I rapidly insert and remove filament a few times. This usually makes the ball spring back into place and resistance when inserting filament returns. In my case it's purely mechanical and happens when the filament runs out or on filament unload/change. Not during print.

Tried without result. This is a big problem, every now and then my prints stop and ask me to change the filament. They force me to keep the sensor disabled. Where can I track the progress of this issue officially?

You bring up a point to consider. I am not having any spaghetti or layer issues but I was reminded when upgrading to the stable 5.0. That I had noticed that this usb drive supplied by Prusa is acting odd when placing it in my computer. Odd meaning slow and takes a long time when unmounting it. I have been using PrusaLink to send jobs to the printer and only see this when upgrading firmware. I would dismiss this but I recently bought a 1TB USB drive that demonstrated similar attributes and other people were reporting similar issues. I will try another USB drive later today and report back my findings.

Strictly the Prusa supplied ADATA USB sticks. And now that you have me thinking about it, ALL of the models and FW updates have used those sticks; I've not yet put a non-Prusa supplied USB stick into my MK4.

I'm going to be curious to see if the new 5.0 release is working any better after I finish printing my sub-woofer v2 cab from Hexibase (which thus far is SWEET under 4.7.2, and my first "multicolor" print attempt). I may do a full calibration after updating the FW just to be sure it's not something else that knocked itself off spec while I was testing 5.0-RC.

Question for anyone that had spaghetti and layer shift....

- What USB dongle are you using ?

1) PRUSA Original

2) Other vendor (indicate the manufacturer and dongle model and size)
