e0stop kills board?

[pro3d]

Something blew on my board when I tried to add a simple filament switch. I did manage to attach gnd to 3.3V and + to gnd... Does this kill the whole thing? It now seams totally dead and I can find no burnt fuses

@pro3d Can you describe:

• How you hooked up the switch?
• Which Duet board?
• What kind of switch?

Did you check the fuses?
Do any LEDs light up?

See how far you can get.

Oh.. sorry for lack of info

I hooked up gnd to 3.3 and + to gnd and signal to signal.

Switch is just a standard mechanical endstop switch

One blue led lights up but everything is dead
Fuses are all fine

@pro3d You "hooked up gnd to 3.3"?

That would cause a short-circuit on the 3.3 Volt power supply and could cause either the 5Volt or 3.3 Volt (or both) power supplies to fail.

@pro3d but why? A normal switch(2 pin endstop uses the GND and signal pins on duet board? Why would you use the 3.3V pin?
probably blew up the 3.3v line and 5v line....

@weed2all
The endstop did have 3 pins. gnd, + and signal. It was a filament detector switch that is basically just a microswitch sof some kind I think. This is how I connected

@pro3d So how far are you able to get? Does the board show up in device manager when connected by USB?

Hey mr. I hav enot been able to chack anything. I pulled the board and replaced it. I can try to connect by usb soon. There was only one blue led lighting up after the kill

Photos of the board may show a blown component. Depending on how extensive the damage was it may be recoverable by a firmware flash...

Which LED specifically is lit when connected to power? What's it labeled as?
