K8400 small fire on extruder board

I have been slowly building my printer and last month I finally got it aligned and turned on but literally right away a small fire started on the printing heads extruder board. Any idea what could have caused this and how I should proceed?


Did you ever found the reason of this fire? I have the exact same issue and found more people online …

Best regards

Hi Gino,

No, we never found the problem or any further information, and have since sold the project.

Best of luck.
