    Hello, so I have an old heater from a robo r1 plus build plate and I want to make a coffee Heater with it. So I want to know what I would need if I were to power it independent of the printer. I know how to sodder and Eire electrical units, so if I could get some input to which electronics to use, I would appreciate it.
    I also have an old robo r1 hotend, so if u know how to power that too, I would love that!

    12v DC is what both take.

    Amps?
    And I want to add a temp variation, could I do that by lowering the voltage through a variable resistor?

    The bed heater output on the RAMPS is limited to 11 amps so it should be less than that. Lowering the voltage? No clue. Might just drive the current up, but you can try. Be safe.

    So is the goal to make the most expensive coffee heater plate you can (between the labor and time you and your dad will spend on making it), or...?

    No, the point is to learn about these technologies by tinkering with them. And a build plate heater is cheep, I have a transformer that meets the requirements and I have a working 3d printer, so I would say it is a cheep project.
