Yesterday my printer worked okay. But i had to change some volt things cause one of the moters was skipping steps. Afterwards i heard a bang, so i’m kinda afraid something got fried. But i dont see any melted or burned parts. And for some reason i cant find any printbed temperature readings

Now i keep on reciever this message

Start by checking the voltage at the blue connector on the control board.
You should see very close to 15 volts DC.
If you see 0 volts disconnect it and check it at the wires.
