      Hello everyone, I am in a new project. In general lines it is a dispenser of cold gels. I cool it with a peltier cell. But when doing the initial tests the generic hotend thermistor does not drop below 27 degrees, when the peltier cell is clearly below zero degrees. I do not know if it is a matter of setting the thermistor values or it is not the right thermistor. I have read that low resistance thermistors are recommended for low temperatures.
      On the other hand, how could you configure the firmware to handle negative temperature in the same way as it would positively. that is, I have to make the board send energy to the peltier to achieve zero degrees. I hope it is understood. Thank you.
