CODE key:2111 Severity: High Difficulty: Intermediate

Nozzle Heater Open Circuit

Error key 2111 triggers when the MCU firmware detects an interruption in the ceramic heater loop during a heating command. The thermal protection algorithm trips when no current draw is registered, flagging an open circuit across the hotend heater terminals.
