Orca Slicer Main Errors – Solution

A clear, beginner‑friendly path to fixing eight frequent Orca Slicer issues is below, with step‑by‑step instructions and concise terminology so you can get back to reliable prints fast. This guide focuses on practical changes inside the slicer rather than theory, helping you diagnose and correct settings that most often trigger failures or confusing behavior.

ACCESS_VIOLATION crash when slicing with 0 mm fuzzy skin point distance

This crash is often caused by invalid Fuzzy Skin parameters like a zero point distance, which can generate degenerate toolpaths during slicing. On marginal hardware or complex models, that unstable patterning quickly surfaces as an Orca Slicer crash.

Solution Steps

• Set Point distance to a non‑zero value (e.g., 0.3–0.6 mm) and re‑slice the model.
• Keep Fuzzy Skin thickness at or below your outer wall line width and aligned to nozzle size.
• If instability persists, switch the Fuzzy Skin generator mode to Extrusion and try again.

Line Infill Not Anchoring to Walls

Small gaps between infill and perimeters signal low overlap or poor anchoring, reducing strength and top‑surface quality. This is a classic case of infill not anchoring at the infill – wall interface.

Solution Steps

• Raise Infill Wall Overlap to roughly 10–15% for stronger bonding.
• Enable infill anchoring so short tie‑ins connect infill lines to nearby perimeters.
• Preview the interface in 3D and adjust internal line width modestly if gaps remain.

Input Shaping calibrations set Pressure Advance value at 0

After input‑shaping routines, some users find Pressure Advance unset or zeroed in the filament preset, leading to corner bulges or ringing. Save a measured PA into the active filament to keep input shaping settings and extrusion timing consistent.

Solution Steps

• Run a Pressure Advance test (tower or line), note the optimal PA, and save it to the filament profile.
• Confirm printer or firmware configs aren’t overriding the slicer’s value.
• Re‑slice and verify corner quality at normal print speeds.

G‑code preview doesn’t scale properly (can’t read SHAPER_FREQ_Y)

Preview scaling glitches often happen when firmware placeholders (like input‑shaper frequency) are missing or mis‑matched in the output template. Correcting those variables and re‑slicing typically eliminates the G-code preview issue.

Solution Steps

• Complete input‑shaping calibration so required frequency values are defined.
• Remove unknown or unsupported placeholders from the G‑code template.
• Re‑slice, then confirm preview scale and motion cues look normal.

One Wall on Top Surfaces causes random internal wall issues

Thin roofs with a single top wall can create unstable internal wall generation or weak coverage, especially on small features. Slightly thicker roofs and adaptive walls stabilize transitions around top surface walls.

Solution Steps

• Increase top shells (e.g., 4–6 layers) instead of relying on a single decorative wall.
• Use an adaptive wall generator to maintain strength on thin features.
• Review “Walls and Surfaces” in Preview to confirm consistent roof coverage.

Wall order ignores bridges – bridge infill order

If bridging isn’t recognized or sequenced properly, the slicer may attempt infill before perimeters that should support it. Tuning bridge detection and ensuring correct order prevents unsupported spans and fixes bridge infill order problems.

Solution Steps

• Enable and tune bridge settings (angle, speed, and flow) so spans are correctly detected.
• Prefer perimeter sequencing that lays bridge supports before internal bridge infill.
• Inspect bridge layers in Preview and iterate speeds/flows until spans are stable.

Filament warning asks to press non‑existent “Confirm”

A mismatched or stale preset bundle can trigger a dialog that references a button which isn’t present. Refreshing presets and restarting clears the orphaned state tied to a filament preset missing condition.

Solution Steps

• Update to a stable build, reload default preset bundles, and reopen the project.
• Duplicate the current filament to a fresh user preset and select it again.
• Restart the slicer and re‑slice to confirm the dialog disappears.

Custom “Anycubic PLA Silk” filament not showing in user list

If a filament isn’t saved under the user namespace or filtered out by the UI, it won’t appear in menus. Ensuring it’s a proper user preset restores visibility for your custom filament profile.

Solution Steps

• Save the filament as a User Preset and verify filters include User items.
• Confirm the filament’s technology matches the active printer profile.
• Restart the slicer and reselect your Bambu printer profile to refresh the list.

Conclusion

Most of these problems come down to small but critical settings: sensible Fuzzy Skin parameters, reliable anchoring, calibrated extrusion timing, and consistent preview variables. With a handful of checks and saved presets, you’ll convert unpredictable behavior into repeatable results across multiple filaments, printers, and models.
