      Hey guys.

      i am currently developing cooling system with PID control, mounted in my 3D printer.
      i am using rrf, but all PID control that i could find was PID temp control at 220 ~ 260C range.
      i need temperature range from RT ~ -10C.
      Is it possible to regulate temperature to minus degree celcius using rrf firmware?

        @roken22 currently RRF does not provide built-in facilities to use PID to control a Peltier or similar device to cool devices below room temperature. However, I think it may be possible to write a simple PID controller using conditional GCode in the daemon.g file.

            @dc42 and temperatures between 0 and 10 degrees? because I tested with my thermistor and it does not drop more than 27 degrees when the peltier has exceeded -10.
