Ultimaker Board 1.5.4 upgrade to 24V, Ardunio not being powered

Posted · Ultimaker Board 1.5.4 upgrade to 24V, Ardunio not being powered

Hi,

I've upgraded the electronics board to 24v by switching out the voltage regulator with the RECOM R-78C12-1.0.

Even though i have previously implemented the fix neccessary for the UltiController with the wire going from Vin to the 12V fan+, the Arduino and the Ulticontroller nor the cooling fan for the electronics are not being powered.

When i connect the Ultimaker via USB everything works fine and i can control all the motors. When i remove the 24V power the controller and the fan stil run, but I'm not able to control any of the motors.

What could be the problem here?
