      under temps are going to happen: the static no fan ambient temp is hotter than circulating fan air so when the chamber fans go on the temps will go down until heats are seen everytime you apply chamber on from ambient temps i would expect a dip first it is naturally going to happen
      if the probe is too close to the heater you will not accheve the real setpoint where it is needed calling off the heats to soon

        @rexx I agree - its frustrating. However, I do understand why the fault tolerances were tightened they way they were. It just doesn't translate well to chamber heaters.

        You know, I shouldn't even suggest this, but.. it would be possible control your heater's SSR through daemon.g and just toggle it on and off based on a set temp. That is not a good long term solution, and bypasses all protection, but.. it would work.

          this is likley what i need as the chamber has thermal snaps eveywhere OEM so is partially safe from over temps the thing is it would be nice to catch a latched SSR on over time out this is all i wanted the duet to do

          heater timed out......5,10,15 min to easy i guess... i will try to learn about this DAEMON.G thanks again!

          super cheers for the help here🥃

            the other option that would really bite but is possible put the chamber heats on a sepeperate outboard controller and call it a day and delete all chamber crap from the configs i feel this is a key part to duet and am shocked this is still a loose end for such a key component i wish i would have know before hand and just built it this way instead perhaps......

            but i was pretty sure this would have not been an issue i was wrong! rolling in my hand a T-100 1/2 din TCcontroller wishing i would have not bought the j type daughter board to keep the oem thermocouple then was the clear choice

            there is allways more than one way to skin a cat! where to start is again the question...kick this one down the road abit longer or just replace it!
