Heated Bed Wiki page Ultimaker

Recommended Posts

You can drive them directly from the Ultimaker PCB. The setup is however a bit tricky.

I don't understand this statement. So can we drive the PCB heated bed from the UM power supply (eg, plugging directly into UM motherboard)? Is the power supply capable of supplying enough power? Are we REQUIRED to have another power supply to power the heated bed?

Has anyone tried powering it directly without adding another power supply or another board, etc??

You need to add a separate supply, the UM power supply cant deliver enough power (75-100W for the heated bed + 60W for the PCB itself) without shutting down first. So you need some sort of power relay board with a separate power supply to make it function properly.
