i was printing in usually way it work just fine.
than, i heard a bang sound and when i went to check i discovered that my expansion board has black mark on its CPU chip.
i wasnt operating it at the moment but later when i check it it didnt was functional, the fuse light gone only the blue one was on.
i dont know what was the cause the bang i had to replace the board after.
anyone experienced the same?
thank you beforehaed.
Hi @moo16 It sounds like there was a short between your VIN power and another signal on the expansion board. Please carefully check your wiring ans that sort of short may only occur when it is bent in a specific way.
everything look good.
i replaced the board with new one and works good.
Where and when was it purchased? Can you post photo of the damage?
