How to Fix Stringing on the Elegoo Centauri Carbon

Stringing on the Elegoo Centauri Carbon is molten filament oozing during travel moves, and it is fixed in this order: dry the filament, lower the nozzle temperature a few degrees, then tune retraction in ElegooSlicer. Because ElegooSlicer is an OrcaSlicer fork, the settings and the fix are the same as OrcaSlicer, changing one variable at a time.

Start with the filament

Wet filament is the single most common cause, and no slicer setting fixes it. Moisture flashes to steam at the nozzle and pulls material into strings. Dry the spool before touching settings, especially with PETG, TPU, PA, or anything left open to air. The Centauri Carbon's enclosed chamber helps keep filament warm during a print, but it does not dry a spool that was already wet.

Drop the temperature

Printing hotter than the filament needs is the next cause. Run a temperature tower and use the lowest temperature that still gives solid layer adhesion. Too-hot filament oozes no matter how good your retraction is.

Tune retraction

In ElegooSlicer, on the filament or printer settings:

1. Increase retraction length in small steps until strings clear.
2. Keep retraction speed reasonable, not maxed.
3. Enable wipe while retracting so the nozzle clears ooze on the way out.

Starting points by material

Stringing settings depend heavily on the filament, so dry the spool first, then start from these and tune with a stringing test. The Centauri Carbon runs a direct-drive extruder, so retraction distances stay short:

Filament	Nozzle temp	Retraction	Notes
PLA	200 to 210 C	0.6 to 1 mm	Strings usually mean too hot or wet
PETG	230 to 240 C	1 to 2 mm	Very prone to stringing; drying matters most
ABS / ASA	240 to 260 C	0.6 to 1 mm	Keep the chamber warm, avoid over-cooling
TPU	220 to 235 C	shorter, slower	Flexible filament strings easily; slow travel helps
PA / CF blends	per spec	per spec	Dry aggressively, these absorb moisture fast

Longer retraction is not better. Too much grinds the filament, so raise it in small steps only until strings clear.

Work the problem in order

If it is still stringing, change one thing at a time in this order, printing a quick test between each:

1. Dry the filament. No setting beats a wet spool.
2. Lower the nozzle temperature 5 C at a time until strings stop.
3. Increase retraction length slightly, then enable wipe while retracting.
4. Reduce travel-related ooze with a consistent Z seam and less Z-hop.

Working top to bottom isolates the cause instead of changing several things at once and not knowing which fixed it.

The Z-axis wisps

Fine strings that show up as the nozzle changes layers usually come from Z-hop travel and the Z seam:

• Reduce or disable Z-hop if you do not need it, since every lift adds a travel move that can trail filament.
• Set a consistent Z seam position so the layer transition happens in one predictable place instead of smearing across the surface.

Why this matters for a print farm

Stringing is a per-filament, per-machine tuning problem, and the settings that fix it should be captured once, not rediscovered each run. Across several Centauri Carbons, a single drifting profile can string a whole batch.

Printago keeps tuned filament and printer profiles centrally in the cloud slicer and slices with the same OrcaSlicer engine ElegooSlicer is built on, so a dialed-in, string-free profile applies across the queue. See what slicer to use for the Centauri Carbon and print farm slicing.
