[P1S] Random pause print and AMS Pull/Push and continue

Bambu Lab AMS
1

Hi, I’m experiencing very strange behavior.

Randomly, with different filaments and in different prints, the printing is simply paused, the AMS pulls the filament, pushes the SAME filament and continues, out of nowhere, randomly.

Obviously this causes printing problems.

I can guarantee with 100% certainty that there is nothing in the slicer to instruct this.

It also happens with different files / gcodes.

It’s likely sensing too much strain while pulling the filament from the ams. It will do this as an attempt to fix it.

Think I found out what it was, the buffer spring was out of place, it didn’t happen again, I’ll monitor it.

I found the bug, is in Time Lapse G-Code, have a clear instruction to make mysterious movements in layer 3, I remove this code and, done.
