MMU3 startup rattling sound?
I have MMU3 on my Core One. I believe all started when i updated Core One with latest 6,.3.5 alpha FW (but i0m not 100% sure)...
anyway: when i power-up my printer MMU3 executes power-on-check and within that it also rotates idler both ways until limit. When doing that in both ways i get annoying rattling sound when it hits hard-limit (like grrrrrrrrr). Is that normal?
I recorded a short video - i intentionally unscrewed idler to show what's happening.

I just talked with Prusa support and supposedly this is normal startup procedure (for anyone wandering the same thing).
