jason_hk heated bed kit set up question

Recommended Posts

Im assuming you have a UM1?

You need a bigger/additional power supply and a DC relay or better mosfet... As an alternative to the whole relay business, you can swap your entire electronics for something better that can actually handle a heated bed, which is what I did when installing that same heatbed kit.

I went with a RUMBA card and stepped the whole machine up to 24V running off a single 300W power supply mounted under the printer... Anothe option could be the cheap and reliable Ramps (you already have the Arduino), those are 12V.. So in any case you need a new PSU and you probable have to swap the 19V cartridge in your hotend to match the new voltage as well...

Hi Maarten,

I think that is no issue at all to make a separate control. The only difference would be that you would have to heat up the bed until it is stable yourself before starting the print. When the print is done you would have to turn it off.

But connecting it to the printer makes it a little easier since when the print starts it heats up the bed automatically and when done it turns it off. You could still use a separate power supply for the be bed if you like.

Knowing your electronics helps a bit when doing these kind of modifications.
