P1S + AMS: Clogged Extruder after Priming (after changed filament)

[visualdensity]

@KanneKaffe

Does it really occur during the filament change? And does the printer otherwise print properly? And after how long does it occur? Already in the first few minutes or only after a longer period of time? I print smaller objects with filament changes, so if the filament is changed every two minutes, for example, but the problem does not occur until, say, the tenth change, it should very clearly be the heat development upwards in the print head. This was the case with my printer when it always changed between PETG and PLA because PLA was the support material.

Morning! Love your questions!

Note: All my filaments across 4 slots are the same Polyterra PLAs. So, there’s no material type change. Just color change.

• 1. Does it really occur during the filament change?
  Yes - only during filament change and very importantly, after priming tower, which indicated that extruded and printed correctly before it resumes printing

• 2. And does the printer otherwise print properly?
  Yes - single filament, same slot/filament via AMS prints perfectly

• 3. And after how long does it occur?
  This was a really small 10m print. The filament change occurs about halfway through, so between 5-6 mins into the print and this is the first filament change. If referring to the AMS itself, I’ve only got it for about 2 weeks now.

• 4. Already in the first few minutes or only after a longer period of time?
  As #3 above, this happened just a few mins into a small print. I need to test on a larger print to see if the same thing happens, although I really don’t look forward to disassembling it again to remove the clog
