PVA settings for the Anycubic Kobra 2

✓ Great match Advanced Support

These are hardware-tuned starting settings for printing PVA 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 PVA's ideal range (185–215°C), that lands us at 200°C nozzle and 60°C bed. PVA dissolves in water for clean supports but is very moisture-sensitive and must stay dry.

Quick answer: 200°C nozzle · 60°C bed · 42 mm/s · 1 mm retraction · 50% 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 185–215°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.

PVA brands & what to expect

PVA is a dissolvable support material that pairs with PLA. Brands differ in how cleanly they dissolve and how quickly they absorb moisture — and all of them are extremely moisture-sensitive.

🔎 PVA that has sat out in humid air turns to jelly in the nozzle and clogs. Keep it sealed with desiccant and only open it to print; treat any printing trouble as a moisture problem first.

Common PVA problems on the Anycubic Kobra 2

SymptomLikely causeFix
Clogs / stringingAbsorbed moistureDry thoroughly and print from a sealed box.
Supports won’t dissolve cleanlyWater too cold / not enough timeUse warm water and agitation; allow more soak time.

On the Anycubic Kobra 2 specifically: it is a fast machine, so if PVA looks rough, drop speed before blaming temperature — many "quality" issues here are really the hotend not keeping up with the flow.

FAQ

What temperature should I print PVA on the Anycubic Kobra 2?
Start at 200°C for the hotend and 60°C for the bed, then run a temperature tower across 185–210°C to dial in your exact filament brand. Our temperature tower planner builds the tower for you.
What print speed works for PVA on the Anycubic Kobra 2?
Around 42 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 PVA?
Use about 1 mm of retraction (direct drive needs very little). If you see stringing with PVA, raise retraction speed before distance and dry the filament first.
Do I need an enclosure for PVA on the Anycubic Kobra 2?
No, PVA prints fine in the open on the Anycubic Kobra 2.
Do I need a hardened nozzle for PVA?
No. PVA is not abrasive, so the stock brass 0.4 mm nozzle on the Anycubic Kobra 2 is fine.
