Strictly speaking, you are not supposed to put any external object, apart from the necessary components and parts for the machine to work properly, inside the machine, as it might interfere with the movement of the moving parts and potentially cause damage to the object itself and the machine. However, if you accidentally leave something under the heated bed, the Homing Stall Detection feature will prevent possible damage to the machine and the object.
Homing Stall Detection works only for objects in the homing path of the heated bed along the Z-axis direction.
Entry to enable/disable Homing Stall Detection on the Touchscreen: Settings > Machine Settings > Homing Stall Detection.
For when Homing Stall Detection will be triggered, how the machine will respond, and what you should do afterwards, refer to the table below.
| Homing Scenario | Condition | Homing Stall Detection | Result | User Action | Note |
|---|---|---|---|---|---|
| Homing at the start and the end of printing | Something is in the homing path of the heated bed along the Z-axis direction. |

Homing Stall Detection, even if on, will not be triggered when there's any obstacle in the homing path of the two extruders along the X-axis and Y-axis direction. Therefore, if such a case occurs, the two extruders will constantly try homing, causing damage to the obstacle or the machine. In the end, the machine will freeze and no longer respond due to the failure to go homing. What you need to do in such situations is:
But always remember first and foremost: Do NOT put anything else inside the machine. |
