PLA-CF settings for the Qidi Q1 Pro

✓ Great match Intermediate Engineering

These are hardware-tuned starting settings for printing PLA-CF on the Qidi Q1 Pro. The Qidi Q1 Pro pairs a direct-drive extruder with an all-metal hotend inside an enclosed chamber, and tops out at 350°C hotend / 120°C bed. Against PLA-CF's ideal range (205–230°C), that lands us at 215°C nozzle and 60°C bed. Carbon-fibre PLA is stiffer and matte but the fibres chew through brass nozzles fast.

Quick answer: 215°C nozzle · 60°C bed · 70 mm/s · 0.8 mm retraction · 100% part fan. Change one setting at a time and validate with a small calibration model.

Calibration order

  1. Dry the spool if it shows moisture symptoms, then confirm the nozzle and build plate are clean.
  2. Print a temperature tower inside the 205–230°C range; pick the lowest temperature with strong layer bonding and clean overhangs.
  3. Calibrate flow, then pressure/linear advance if your firmware supports it.
  4. Tune retraction last — more distance is not always better, especially on the direct-drive Qidi Q1 Pro.

PLA-CF brands & what to expect

Carbon-fibre PLA prints at PLA-like temperatures but the abrasive fibres are what matter — every brand will destroy a brass nozzle. A hardened steel nozzle is mandatory regardless of brand.

🔎 CF-PLA is stiffer and has a premium matte look, but it is not "stronger" in every sense — it’s more rigid and slightly more brittle. Great for parts that must not flex, less good for parts that take impacts.

Popular PLA-CF brands: eSUN, Overture, Polymaker, Bambu Lab.

Common PLA-CF problems on the Qidi Q1 Pro

SymptomLikely causeFix
Rapid under-extrusionBrass nozzle worn or cloggingSwitch to hardened steel; a 0.5–0.6 mm nozzle helps.
Rough / fuzzy surfaceSlightly cool or worn nozzleSmall temp bump; inspect the nozzle for wear.

On the Qidi Q1 Pro specifically: fit a hardened nozzle before running much PLA-CF — the stock hotend still uses a brass nozzle that wears out fast on abrasive filament.

FAQ

What temperature should I print PLA-CF on the Qidi Q1 Pro?
Start at 215°C for the hotend and 60°C for the bed, then run a temperature tower across 205–225°C to dial in your exact filament brand. Our temperature tower planner builds the tower for you.
What print speed works for PLA-CF on the Qidi Q1 Pro?
Around 70 mm/s is a safe starting point. This printer can go faster once the profile is tuned, but start conservative for clean walls. Check your real speed ceiling with the max volumetric flow calculator.
What retraction should I use for PLA-CF?
Use about 0.8 mm of retraction (direct drive needs very little). If you see stringing with PLA-CF, raise retraction speed before distance and dry the filament first.
Do I need an enclosure for PLA-CF on the Qidi Q1 Pro?
No, PLA-CF prints fine in the open on the Qidi Q1 Pro.
Do I need a hardened nozzle for PLA-CF?
Yes. PLA-CF is abrasive and will wear out a brass nozzle quickly — fit a hardened steel or ruby nozzle before printing much of it.
