Topic: wiring a pcb and a thermistor

Hi I was just curious on how you wire a thermistor and pcb together for the solidoodle 2 i figure you just wire them together in parallel  and take the two wires solder them to a 2 pin connector but i wasnt sure if this is correct any help would be great  c: i bought a pcb and a separate 100k thermistor.

Re: wiring a pcb and a thermistor

Your question doesnt make sense to me.  I would encourage you to lay it out more clearly.

Thermistor and PCB heater are separate.
PCB heater goes to a 4-pin connector near one of the mosfets in the bottom of sanguinololu. Thermistor connectors to a 2-pin connection near top. IF you use a printrboard this is different.

Confused. Sincerely,

Wire the thermistor to the existing thermistor wires and the pcb heater to the existing bed heater wires.  In case you are confusing a thermistor with a heating resistor, a thermistor is a temperature sensor.  If you want to wire an old heating resistor in parallel with a new printed circuit board heater I doubt the standard board could handle the combined load and you'd wand to wire in a relay and separate power supply.
