Thermistor reading high temperatures
May 13, 2016 09:52PM
Hello all,

I'm new to the forum. I bought myself a folger tech 2020 i3 prusa aluminum 3d printer kit and just finished building and configuring it. I followed the building and consiguring guides rev B. When my printer was ready to print I noticed that the repetier software was giving weird temperature readings of 189 C for the heated bed and extruder. The heated bed stays at 189 without changing and the extruder reads from 188 and 189 C. That's at room temperature. When I activate the extruder, it starts getting hot but the software will keep reading the same. I double check the wiring already and it seems to be right. The fact that I'm getting this readings means the thermistors are responding in some way.
Any suggestion or similar cases?
