My heatbed does not work properly. It lights up with the red LED for a while, but the temperature does not raise above room temperature on the screen. Also the bed does not get hot. After a while the LED is turned off and the printer seems to lock up. The touch-screen works, but move-commands does nothing.
I have measured the voltage on the mosfet and at the connections on the bed, they both show 24V.
Is there anything else i could try?
