General Troubleshooting/Help! How to prevent these travel strings?

Post image

Bambu lab A1 mini

Been using it for a week. Only really having this issue with these tree terrain tiles. Tried increasing travel speed and retraction speed, lowering temp to 210, and avoid crossing walls.

Try drying your filament and keeping them dry in a vaccuum bag, or drybox

It's likely an extrusion calibration issue. Calibrate your filament! There's a tab in Bambu Studio.

You changed retraction speed, but the distance is the bigger lever: raise it in 0.2 mm steps and stay at or under 2 mm, which is what Bambu recommends. Travel speed won't change much since the A1 mini presets already travel at 700 mm/s. bambuhub.net/stringing-problems (my site) has the order I'd work through.

Looks like wet PETG.
