Hardware needs to be sorted out first. PT100 sensors utilize an amplifier circuit. This amplifier needs to be bypassed before any of the more typical thermistors is utilized. In another thread Mechanikus mentioned that the amplifier circuit was a part of the hotend assembly. If true, it should make it easier to bypass.
