duet exp3hc lost connection with main board

Hi,
Unfortunately when I connected the
Exp3hc to the power and can, I saw Smoke from the endstop conectors area, (never used them),dont think its right to use it,
I did conect only red and black and the can cable,Any idea?

Can you post some photos of the wiring and damage?

Attached photo,
The exp3hc is not conect now to main board /power
I used the exp3hc only for X axis and extruder '

Can you show a closer photo of the circled area with more light?
What LEDs are lit on the expansion board if any when it is connected?

-
Can you describe for us how and what you had connected to the expansion board at the time it failed?
-
-power from main board (+-) as shown in the photo
-X stepper was conect to driver 1
-extruder stepper was conect to driver 2
-RJ11 cable was conect to can in from main board
nothing else was connect to that boardI did use for cables connectors that I got with the board

The connections sound pretty standard. This may be a case of premature component failure.
When and where did you purchase the board? It may be covered by warranty.
