      I read a few posts that talk about peltier heating OR cooling and also found one post that talks about both together but I believe it is still incomplete.

      i know i need to use a relay to switch on and OFF the peltier and a DPDT/H-bridge to switch polarity on the peltier.

      But on the firmware side, i am new with 0% programming knowledge so i need some help there. I read on one post, where David said its not in Heat.cpp but in pid.cpp

      https://forum.duet3d.com/topic/5057/reverse-polarity-of-heater-peltier-heating-cooling/31

      But what next.???
