Idler of MMU3 kind of reset mid-loading?  

Idler of MMU3 kind of reset mid-loading?

Howdy!

I've a weird issue this week. I had no issue at all since my MMU3 (I used Ultimulti mod) upgrade (MMU2S to MMU3).

When I'm loading a filament, the idler kind of "reset" itself after loading at 3/4, so the wheel doesn't grab the filament anymore and the filement stall in the PTFE tube.

I've uploaded a video to show what it does. I included a serial output sample from octoprint.

What could be the issue? PTFE tube too long?

Prusa MK3S+ firmware : 3.13.2 (Revo 6 edition)
MMU3 : 3.0.1
