Hi,

I have a sanguinlolu board, tested the heater bed voltage output its not working. I cant make my filament stick to the glass, using sticky glue and hairspray. Is the MOSFET damaged? How to troubleshoot the board? The connector has a wire burned.
Thanks

These KK256 connectors are rated for 1 Ampére, a typical heated bed needs 10 times of that. Sanguinololus are severely undersized in this area and your specimen doesn't even use the 4 pins available by design. To get the bed working you need a Solid State Relay, e.g. a SevenSwitch.
