Why do my OrcaSlicer prints show ringing or ghosting?

Ringing or ghosting is usually caused by high acceleration and sharp cornering combined with mechanical vibrations. Reducing acceleration and cornering speed and checking belt and frame stiffness helps.

🐋 OrcaSlicer Settings Cheat Sheet

Q: Is OrcaSlicer better than Bambu Studio for tuning?

OrcaSlicer offers more advanced control over speed, acceleration, retraction and Pressure or Linear Advance and works well with Klipper-based printers. Bambu Studio is more streamlined for stock Bambu hardware.

Q: What is a good starting Pressure Advance value in OrcaSlicer?

For many direct-drive PLA setups a Klipper Pressure Advance value between about 0.02 and 0.06 is a common starting range. Use a pressure advance test object to fine tune the value for your printer.

OrcaSlicer excels with fast, Klipper-driven printers. These starting values target typical modern CoreXY and tuned bed-slingers for PLA, PETG, ABS/ASA and TPU.

PLA – Fast but Clean

Nozzle temperature	205–215 °C
Bed temperature	55–65 °C
Layer height	0.20 mm (0.16 mm for nicer walls)
Outer wall speed	80–120 mm/s
Inner walls / infill	150–220 mm/s (printer-dependent)
Retraction (direct drive)	0.5–0.8 mm @ 25–35 mm/s
Retraction (bowden)	3–5 mm @ 25 mm/s
Flow ratio	0.98–1.00
Cooling	100% after first few layers

PETG – Controlled Stringing

Nozzle temperature	235–250 °C
Bed temperature	75–85 °C
Outer wall speed	60–100 mm/s
Infill speed	120–180 mm/s
Retraction (direct)	0.5–1.0 mm
Cooling	20–50% (too high → brittle, too low → blobs)

ABS / ASA – With Input Shaper

Nozzle temperature	240–260 °C
Bed temperature	100–110 °C
Cooling	0–15%
Outer wall speed	60–90 mm/s
Infill speed	120–180 mm/s
Brim / enclosure	Recommended for stability

TPU – Soft & Controlled

Nozzle temperature	215–235 °C
Bed temperature	35–50 °C
Print speed	30–50 mm/s
Retraction	0–0.6 mm (keep low)
Flow ratio	1.00–1.05

Pressure Advance / Linear Advance in OrcaSlicer

OrcaSlicer plays very well with Klipper Pressure Advance and Marlin Linear Advance. General starting guidance:

Direct drive, PLA: PA ≈ 0.02–0.06 (Klipper), K ≈ 0.05–0.20 (Marlin).
Bowden, PLA: PA ≈ 0.05–0.15, K ≈ 0.10–0.30.
Flexibles (TPU): lower PA/K values – too high will starve corners.
Use PrintFix Pro Pressure Advance Notes and print a PA test tower to lock values in.

FAQ – OrcaSlicer Profiles

Is OrcaSlicer better than Bambu Studio for tuning?

OrcaSlicer exposes more advanced PA/LA, speed and acceleration controls and works with many printers, especially Klipper machines. Bambu Studio is smoother for stock Bambu hardware.

What is a good starting Pressure Advance value in OrcaSlicer?

For direct-drive PLA, many printers land between 0.02 and 0.06 for PA in Klipper. Start in the middle, print a PA test and adjust until corners are crisp without gaps.

Why do my fast OrcaSlicer profiles ring or ghost?

Ringing usually comes from high acceleration and sharp cornering. Reduce accel, square-corner velocity or jerk and make sure your frame and belts are tight.
