| When the emergency stop is triggered, the microcontroller board responsible for the stepper motors, heaters and sensors is reset immediately and returns to idle state afterwards. Now it is safe to resolve any problems or defects in the build chamber.\\ | When the emergency stop is triggered, the microcontroller board responsible for the stepper motors, heaters and sensors is reset immediately and returns to idle state afterwards.

| During normal operation it is not necessary to wear special protective gear. Some tasks however should not be performed without taking protective measures. Situations that require protective equipment are specially indicated. It is the owner's obligation to provide adequate protective equipment. | During normal operation it is not necessary to wear special protective gear.

| The extruder nozzle is sensitive to heat treatment and mechanical strain.\\ If the nozzle or extruder barrel are clogged by congealed material, reheating during the normal production flow is utterly sufficient to clear them in most cases.\\ In case you want to change the material type or clogging is effected by foreign particles (i.e. dust grains dragged along with the filament), it is necessary to remove congealed material from the nozzle. The corresponding description can be found in the [[#Cleaning recommendation|cleaning recommendation]]. | The extruder nozzle is sensitive to heat treatment and mechanical strain.\\ If the nozzle or extruder barrel are clogged by congealed material, reheating during the normal production flow is utterly sufficient to clear them in most cases.\\ In case you want to change the material type or clogging is effected by foreign particles (i.e. dust grains dragged along with the filament), it is necessary to remove congealed material from the nozzle.
