OrcaSlicer · PETG stringing & first layers

Clean PETG without another download page

Starting settings for stringing and first layers—dry filament, temperature, retraction, and Z-hop before you chase exotic seams.

If you need how to stop PETG stringing in OrcaSlicer, begin with a dry spool, apply conservative retraction and temperature moves, confirm the first layer, then open a matching guide.

Four-row starting table

Select a row to highlight the matching card. Values are starting points for PETG travel cleanliness—not defaults for every printer.

CheckStarting pointWhy it matters

Dry

Moisture before math

Store opened PETG sealed. If the spool sat open in humidity, dry it per brand guidance, then re-test on a small travel model—not after changing five fields at once.

Temp

Temperature ladder

Use the spool range, not a generic “always 250 °C” tip. Prefer OrcaSlicer’s Temperature Tower on the same spool. If whiskers remain after drying and mild retraction, step slightly cooler and keep bed temp separate.

Retraction

One axis per print

Note direct-drive vs Bowden, nudge one control, print a short stringing test, and back off if filament grinds. Use built-in Retraction calibration when guesswork stalls.

Z-hop

Lift only what you need

Enable a short Z-hop when hairs drag across tops. Keep hop small; if edge blobs appear, reduce hop or revisit temperature.

Five jobs OrcaSlicer handles next

Pick the job that matches the failure on the plate. Each card routes to a verified orcaslicer.net guide.

First layer

When the skirt won’t stick, clean the plate, confirm probe or level, then adjust Z-offset and first-layer speed before raising nozzle heat to mask a high live-Z.

PETG stringing

After drying, pair retraction with modest Z-hop and a calm temperature ladder. Change one variable per test.

Calibration

Use OrcaSlicer’s built-in Temperature Tower, Retraction, Flow Ratio, and related tools—then save kept values to the correct profile layer.

Printer profiles

Keep machine limits on the printer profile; keep PETG temperatures and retraction bias on the filament profile.

AMS caveats

Multi-material paths add drying, purge, and slot complexity. Treat AMS stringing as filament condition plus purge strategy—not only one retraction number.

FAQ

Wet PETG often strings and pops no matter how polished the retract chart looks. Dry first so each OrcaSlicer change means something.
Start from a PETG preset matched to direct-drive or Bowden, change one field per print, and use Retraction calibration for a structured sweep. Back off if filament grinds.
No. Modest Z-hop helps on long travels, but excess hop adds time and edge artifacts. Pair it with drying and temperature discipline.
Separate the problems. Revisit plate cleanliness, probe or level, first-layer height/speed, and Z-offset—not endless nozzle heat to mask a high offset.
