      Good morning I am interested in using a tool board for my pellet extruder.
      Just for the accelerometer, thermistor and endstop.
      Was wondering is it possible to add another thermistor?
      I require 3 for the pellet extruder.

        @hoops40 I don't think a third thermistor could be added without removing a resistor from the tool board, and adding an external pullup resistor.

        Bear in mind that there is a restriction that a heater can only be controlled by a temperature sensor connected to the same board as the heater. This is a safety precaution.
