Hello there,

As i read ramps 1.4 is running 12V ( so power supply should be 12V or 12V) and ia it ok to run ramps 1.4 on
360W 24V.

LAST question:

I used ender 3 heared bed for my custom 3d peinter and its 24V. Whats the risk if i run it on 12V

A standard ramps 1.4 is 12v only!

You need to make modifications to the board. see [reprap.org]

Luckly just making the bed work on 24v volts is easy. I recomend a exernal mosfet and a 24v supply

If you run a 24v heated bed on 12v it will barly get warn.

You clearly want a 24 volt system. Drop the ramps and mega, there are much better controllers that support 24v out of the box. eg SKR 1.4 and it 32 bit.
