There’s a weird noise coming from the toolhead/extruder when I am printing now. It wasn’t there a few days ago. And I am not able to understand exactly where it is coming from. Anyone experience the same, and have any suggestions?
Did you check the underside of the print head? It sure sounds like it’s dragging something…
Didn’t see anything on the offending print head, but I did feel something. Doing a cleaning and reprint now, and will report back later
Start of the print after cleaning sounded fine, but it seems to be picking up some of the PETG underway and starts scraping it around.
Trying to print today it was even worse. Without changing any settings. So, in the dryer the filament goes!
So, here’s the thing.
When I removed the PETG to put it in the dryer, I noticed that there looked to be still some filament in the tube going from the main body to the toolhead. So I removed the tube, and sure enough, there were about 20 cm of PLA stuck in the “bend” of the tube. And also a piece broken off laying down in the toolhead. I hadn’t noticed when I removed the PLA previously that because it was kinda brittle, it had broken off inside the tube.
Removal of this has now made the machine well behaved again.
