Anycubic Kobra 3 V2 + ACE Pro — Material Settings Reference

Multi-color FDM. CoreXY. ACE Pro 4-filament hub. Main workhorse for functional parts, multi-color prints, and prototypes.

Hardware Specs

PLA (Standard)

SettingValue
Nozzle temp215–220°C
Bed temp60°C
First layer bed65°C
Print speed150–200 mm/s
First layer speed30 mm/s
Cooling fan100% after layer 2
Retraction0.8 mm @ 35 mm/s
Layer height0.2 mm (0.1–0.28 mm range)
EnclosureOpen

Notes: Most forgiving material. Stringing on multicolor: increase retraction to 1.0–1.2 mm. PLA+ runs 5°C hotter. Matte PLA needs 225°C and slightly slower speeds.

---

PLA+ / PLA Pro

SettingValue
Nozzle temp220–230°C
Bed temp65°C
Print speed120–180 mm/s
Cooling fan100%
Retraction1.0 mm @ 35 mm/s

Notes: Better layer adhesion and impact resistance than standard PLA. Slightly more prone to stringing. Good for brackets, enclosures, snap fits.

---

PETG

SettingValue
Nozzle temp235–245°C
Bed temp80–85°C
First layer bed90°C
Print speed80–120 mm/s
First layer speed25 mm/s
Cooling fan40–60%
Retraction1.2–1.5 mm @ 30 mm/s
Layer height0.2–0.25 mm
EnclosureOpen

Notes: Hygroscopic — dry before printing (65°C, 6 hrs). Sticks hard to PEI — use glue stick or lower bed to 75°C if removing parts is difficult. Great for mechanical parts, brackets, outdoor use. Stringing is common; keep retraction high and travel speed fast (200 mm/s).

---

TPU (Flexible, Shore 95A)

SettingValue
Nozzle temp225–235°C
Bed temp40–50°C
Print speed25–40 mm/s
First layer speed20 mm/s
Cooling fan30–50%
Retraction0–1.0 mm (minimal)
Layer height0.2 mm
EnclosureOpen

Notes: Direct drive handles TPU well. Print slow — 35 mm/s max or you'll get clogs. Disable or minimize retraction to avoid grinding. No ACE Pro for TPU — load single-filament direct. Shore 85A = even slower (20 mm/s). Dry at 50°C 4 hrs if moisture issues.

---

ABS

SettingValue
Nozzle temp240–250°C
Bed temp100–110°C
First layer bed110°C
Print speed60–80 mm/s
Cooling fan0–20% (very low)
Retraction1.0 mm @ 30 mm/s
Layer height0.2 mm
EnclosureRequired — improvise with cardboard if needed

Notes: Warps badly without enclosure. Brim of 8–10 mm required on anything over 50 mm. Fumes — print in ventilated area or outside. ABS-acetone slurry on bed helps adhesion. Excellent for parts that need post-processing (acetone smoothing), heat resistance up to 100°C.

---

ASA

SettingValue
Nozzle temp245–255°C
Bed temp100–110°C
Print speed60–80 mm/s
Cooling fan0–10%
Retraction1.0 mm @ 30 mm/s
EnclosureRequired

Notes: UV-stable ABS alternative. Use for anything outdoors. Same printing pain as ABS but worth it. Slightly less warp-prone than ABS. Good for car parts, outdoor mounts, enclosure handles.

---

PLA-CF / PETG-CF (Carbon Fiber Filled)

SettingValue
Nozzle temp (PLA-CF)220–230°C
Nozzle temp (PETG-CF)240–250°C
Bed temp65°C (PLA) / 85°C (PETG)
Print speed60–100 mm/s
Cooling fan80–100% (PLA-CF) / 30% (PETG-CF)
Nozzle requiredHardened steel 0.4 mm minimum

Notes: Abrasive — destroys brass nozzles fast. Already on hardened steel. Stiffer, lighter than base material. Good surface finish. Higher strength-to-weight. Use for tooling, jigs, brackets.

---

PA/Nylon

SettingValue
Nozzle temp250–270°C
Bed temp70–90°C
Print speed40–60 mm/s
Cooling fan20–40%
Retraction1.5 mm @ 30 mm/s
EnclosureStrongly recommended
Drying requiredYes — 80°C, 12 hrs minimum

Notes: Extremely hygroscopic. Print same day as drying. Excellent impact/abrasion resistance. Bed adhesion is tricky — PEI with glue stick or Garolite sheet. PA12 is easier than PA6. Good for gears, hinges, functional wear parts.

---

PVA (Support Soluble)

SettingValue
Nozzle temp185–200°C
Bed temp60°C
Print speed30–40 mm/s
Cooling fan50–80%
Retraction1.2 mm @ 25 mm/s

Notes: ACE Pro use — PVA in one channel, main material in another. Dissolves in water (warm water speeds it up). Keep bone dry — absorbs moisture within hours of opening. Print PVA slower and cooler than PLA. Compatible with PLA supports. Store with desiccant sealed.

Multi-Color / ACE Pro Tips

  • Color change purge: 80–120 mm³ purge block minimum per color swap. More for light→dark transitions.
  • Purge into support: Enable in Orca Slicer to avoid large purge towers.
  • Tension: Keep filament paths short and straight to the ACE Pro hub.
  • Humidity: The hub has no dryer — pre-dry hygroscopic materials.
  • Speed during swap: ACE Pro slows print during color change — normal.
  • Max colors: 4 via hub, can extend to 8+ with manual swaps.

---

Calibration / Tuning

  • First layer: Z-offset critical — live adjust first layer to slight squish
  • PA (Pressure Advance): 0.02–0.06 for PLA, 0.04–0.08 for PETG, 0.0 for TPU
  • Flow rate: Calibrate per filament spool — 0.95–1.05 typical range
  • Retraction tune: Print retraction tower per material
  • Temp tower: Run for new brands — find sweet spot for each

Common Issues

ProblemFix
StringingIncrease retraction, raise travel speed, lower temp 5°C
Layer separationRaise temp 5°C, slow down, check filament diameter
Bed not stickingClean PEI with IPA, check Z offset, raise first layer temp
CloggingCheck temp, slow speed, dry filament, check nozzle
WarpingHigher bed temp, brim, enclosure, draft shield
Blobs/zitsTune coasting and retraction
Under-extrusionDry filament, check Bowden, increase flow 2–3%
