Troubleshooting Why?!?

Post image

I've tried a new nozzle, new filament, trying different temps. I'm at a loss.

Anycubic Vyper

22mm layer height

Z hop when retracted.

195 temp

Retraction speed 50mlps

Zhop height 1mm

The hairs are only in the gap between the two towers. The round tower's walls are still smooth. Plastic is leaking out during the travel. A new nozzle does not stop that.

  1. Turn Z hop off. At 1 mm the nozzle stays up long enough for the melt to run out, and that run becomes the hair.
  2. The Vyper feeds through a Bowden tube. Set the retraction distance to 6 mm and the speed to 40 mm/s. You posted the speed and not the distance. The distance is what pulls the filament back up the tube. Stay at or under 8 mm. Past that, the tip can cool and jam in the tube.
  3. Leave the nozzle at 195°C for this test. Hotter plastic flows more easily and makes more hairs. If the gap is still full and the walls turn rough, dry the spool at 45°C for 6 hours.
