Direct answer

Confirmed

For the U.S. evidence set, wait until the filament has cooled completely before removing or unplugging the Kobra S1 hotend. Early removal can leave cooled filament lodged in the throat. The documented hotends are 0.25/0.4/0.6/0.8 mm with a 320 °C maximum, but those specifications never authorize handling while hot.

Low-risk troubleshooting path

Verify one condition at a time

Keep the full fault context and retest after each official step. Never transfer a bare error code across models.

  1. Capture the complete message

    Record the code, complete message, device state and recent operation or maintenance.

  2. Confirm the exact model

    Use only official support steps for this exact model.

  3. Run one low-risk check

    Check power, placement, visible obstruction, sensors or contacts, then retest.

  4. Escalate repeated or abnormal faults

    Stop use for repeated alerts, odor, heat, damage or possible liquid ingress.

01

The stop condition comes first

Do not remove or unplug the hotend until the filament is completely cool. Anycubic warns that premature removal can pull material into the throat and leave cooled filament lodged inside. If full cooldown cannot be confirmed, stop and use official support.

02

Confirm the exact replacement after cooldown

Only after the cooldown condition is met should the replacement be matched to the Kobra S1 quick-release hotend. The U.S. facts list 0.25, 0.4, 0.6 and 0.8 mm, with 0.4 mm included, and a 320 °C maximum. No cross-model hotend compatibility is inferred.

  • Wait for complete cooldown
  • Match the replacement to Kobra S1
  • Stop if the safe condition cannot be met
