ASA settings for the Anycubic Kobra 2

Possible with tweaks

These are tuned starting settings for printing ASA on the Anycubic Kobra 2. The Anycubic Kobra 2 has a direct-drive extruder with a PTFE-lined hotend, so we set the hotend to 240°C and the bed to 100°C. ASA is the UV-stable cousin of ABS and the better choice for parts left in the sun.

⚠️ ASA likes up to 260°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 ASA brands you would need an all-metal hotend upgrade.
⚠️ ASA warps without an enclosure and the Anycubic Kobra 2 is open-frame. Block drafts, raise the bed temp, and add a brim; for tall parts an enclosure is strongly recommended.
💡 Best uses for ASA: outdoor parts, UV-resistant parts.

FAQ

What temperature should I print ASA on the Anycubic Kobra 2?
Start at 240°C for the hotend and 100°C for the bed, then run a temperature tower across 240–250°C to dial in your exact filament brand.
What print speed works for ASA on this printer?
Around 63 mm/s is a safe starting point on the Anycubic Kobra 2. This printer can go faster once the profile is tuned, but start conservative for clean walls.
What retraction should I use?
Use about 1 mm of retraction (direct drive needs very little). If you see stringing with ASA, raise retraction speed before distance and dry the filament.
Do I need an enclosure for ASA on the Anycubic Kobra 2?
Yes — ASA really wants an enclosure and the Anycubic Kobra 2 is open, so expect warping on large parts without one.
