Hey Guys, I'm really glad that I found this topic. I have bought a heated bed kit (http://www.ebay.com/itm/Heated-Bed-Kit-for-Ultimaker-Reprap-3d-Printers-MK2-PCB-Aluminium-plate-/161157442118?pt=LH_DefaultDomain_0&hash=item2585bb6a46), with a proper power supply. My problem is that i don't know which thermistor should i choose at http://marlinbuilder.robotfuzz.com/ firmware generator, and which slot should I solder how big resistance onto. After giving it the first try it said that the bed temp is 357 °C, at room temp (without the resistance soldered). Thanks for your help, regards Denes
