Hi
I am working on a Rostock 3d printer and I had a question about the heat bed. I am looking to use a 240mm round heat bed from Ultibots, but it is 24v instead of 12v, what would it take to run this heat bed on the ramps 1.4?
Here is a link to the heater for the heat bed
24v kapton heater
Thanks

Hi Tanner,
+1 to what Dust answered.
Please note that the link you have provided is for a heater, you will still need an aluminum heat spreader and a piece of borosilicate glass. An alternative, simpler and less expensive solution is to buy a 12V / 24V PCB heatbed for the Rostock, which gives you the option of starting with a simpler 12V setup and upgrading to a 24V power supply (for the heatbed only) at a later time. There is no advantage to having a RAMPS board running at 24V for the electronics and steppers, actually imho it's a PITA and a major risk, considering the currents involved.
