Hi, my first prints have repeatedly been paused due to a message indicating an auxiliary feeder blockage. Apparently, this is a recurring issue with this machine. Is there a solution? I’ve read that it might be necessary to disable the feeder blockage sensor in Klipper. What would be the best solut…

Hi, Have you tried with different filaments ?

No, for now I have only used ABS filament on this printer. The auxiliary feeder is connected to a dryer with a Bowden tube of about 80 cm. Could that create enough resistance to cause the feeder to malfunction?

I don’t know, I don’t own such a printer. Try without dryer just to see.

Read through this thread: [image] Filament feeder failures Sovol SV08 MAX Has anyone else experience failures with the filament feeder? After setting up the printer I printed a few test prints, but each time I printed something, the print would pause during t…

Some tubing introduces quite a bit of drag. I’ve had some the aux feeder wasn’t happy with. Is it clear tubing, by any chance? Try a different length of PTFE tube on it, or even just ditch the tubing between the drier & feeder temporarily, for testing.

The PTFE between the dryer and the feeder is a Capricorn. I’ll try with the filament directly on the spool holder. Is it a problem if the filament is warm because the drying process isn’t finished yet? If I’ve read the thread correctly, the solution mentioned is to install the “3dprintdemon Klippe…

[image] LeoG: Is it a problem if the filament is warm because the drying process isn’t finished yet? Normally, a dryer “dries” the filament. The temperature of the filament leaving the dryer is 60°C maximum and cools very quickly before reaching the nozzle.

Sorry, what I meant about this is that when I had print interruptions with a feeder blockage message, the dryer was still drying the ABS filament and was set to 80°C. If the filament is hot, can it stick or create more friction in the PTFE tube, or does it expand and move more difficultly inside th…

I can’t be sure but 80° for PTFE it’s very low
