Nylon (PA) settings for the Anycubic Kobra 2

⚠ Possible with tweaks Advanced Engineering

These are hardware-tuned starting settings for printing Nylon (PA) on the Anycubic Kobra 2. The Anycubic Kobra 2 pairs a direct-drive extruder with a PTFE-lined hotend on an open frame, and tops out at 260°C hotend / 110°C bed. Against Nylon (PA)'s ideal range (240–280°C), that lands us at 240°C nozzle and 90°C bed. Nylon is extremely strong but soaks up moisture fast, so dry the spool before every print.

Quick answer: 240°C nozzle · 90°C bed · 56 mm/s · 1.5 mm retraction · 0% part fan. Change one setting at a time and validate with a small calibration model.

Flow / extrusion multiplierStart at 100%; calibrate flow before touching retraction
DryingStrongly recommended — dry before printing if you hear popping or see inconsistent extrusion
⚠️ Nylon (PA) can want up to 280°C, but the Anycubic Kobra 2's PTFE-lined hotend caps it near 240°C — going hotter degrades the PTFE tube and releases fumes.
⚠️ Because the Anycubic Kobra 2 is not all-metal, keep the hotend at or below 240°C. For the hottest Nylon (PA) brands you would need an all-metal hotend upgrade.
⚠️ Nylon (PA) warps without an enclosure and the Anycubic Kobra 2 is open-frame. Block drafts, raise the bed temp, add a brim, and consider a simple enclosure for tall parts.

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 240–280°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 Anycubic Kobra 2.

Nylon (PA) brands & what to expect

Nylon (PA) is the most moisture-sensitive common filament, and grades differ hugely — PA6, PA12, glass- and carbon-filled all print differently. What they share: they must be bone-dry, or they hiss, foam and print rough.

🔎 Nylon can pull enough water out of the air to ruin a print in a couple of hours on a humid day. Print straight from a dryer, not just "dry it once" — many people run nylon out of an active dry box.

Common Nylon (PA) problems on the Anycubic Kobra 2

SymptomLikely causeFix
Popping, steam, rough surfaceWet filament (almost always)Dry 6–12 h and print from a heated dry box.
Poor bed adhesionNylon resists stickingUse a PA-specific sheet or glue stick; enclose to hold heat.
WarpingHigh shrinkage + open frameEnclosure, brim, minimal cooling.

On the Anycubic Kobra 2 specifically: it is open-frame, so the warping fixes above are the ones that matter most — an enclosure or draft shield does more for Nylon (PA) here than any slicer tweak.

FAQ

What temperature should I print Nylon (PA) on the Anycubic Kobra 2?
Start at 240°C for the hotend and 90°C for the bed, then run a temperature tower across 240–250°C to dial in your exact filament brand. Our temperature tower planner builds the tower for you.
What print speed works for Nylon (PA) on the Anycubic Kobra 2?
Around 56 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 Nylon (PA)?
Use about 1.5 mm of retraction (direct drive needs very little). If you see stringing with Nylon (PA), raise retraction speed before distance and dry the filament first.
Do I need an enclosure for Nylon (PA) on the Anycubic Kobra 2?
Yes — Nylon (PA) really wants an enclosure and the Anycubic Kobra 2 is open, so expect warping on large parts without one.
Do I need a hardened nozzle for Nylon (PA)?
No. Nylon (PA) is not abrasive, so the stock brass 0.4 mm nozzle on the Anycubic Kobra 2 is fine.
