At that point it just cycles back and forth like it is wiping, but no filament is extruded. After about five minutes of this, it retracts the filament and makes the change. Next filament change results in the same cycle.

All kind of funny when I got an email telling me how fast the new firmware would change filaments.

Filament: PCTG - 3D Fuel

When I get a chance, I'll try the same model with PLA to see if that is connected.

This started about 3 weeks ago, I have not been able to print. I've had this CORE ONE for about 5 months. The noise was very noticeable. I disassemble the extruder, cleaned the gears and put it back in place. I tuned the belt and recalibrate everything. The sound got somewhat better but it is still not printing right. Not sure if is the motor the nozzle ( which I also cleaned many times).

I've just updated to the "new" firmware, and on my first print I had the layers shift.  This happened three times.  The culprit is the wipe tower.  For some reason, large blobs of filament are deposited into the wipe tower on filament change.  Eventually, the buildup will cause the extruder to drag and the motors will skip steps.

This is happening on my CoreOne+.  I've got the Coreboxx on top with active smart rewinders by @mire.

I've tried adjusting settings on the wipe tower, and it makes no difference.  Eventually the extruder crashes and ruins the print.  I've tried this print three times now.

All of a sudden I'm being notified that PrusaSlicer is trying to connect with 86.165.229.84 (normally IP addresses are resolved to a domain by a suitable DNS so the fact that this isn't resolved is itself suspicious) - does anyone know what this IP address is?

Home network addresses are always 192.168.x.x so this isn't a local connection.

I'm running PrusaSlicer v2.9.4 and this connection pops up whenever I select the camera (buddy cam) in Prusa Connect

While using the PrusaSlicer preset for my CoreOne+ and the Prusament PETG V0 material, the prints had really poor adhesion leading to multiple print failures. The regular Prusament PETG never gave me this kind of problems with the default profile. The problems persisted with both satin and textured sheet, no matter how well I cleaned it. The filament itself was well dried (which is important for V0), holding at 22% humidity in a dry box.

Finally, I tried increasing the nozzle temperature from 230°C (preset) to 235°C and all the problems just vanished. I think I could comfortably go even higher. Do you have similar experience? Should I try to push the 235°C as a new default profile for V0?

I printed some test files linke temp Tower and speed test as well.

  1. How do i get rid of the stringing especially in the last picture?
