      @jrockland you can see everyone is very interested with the amount of people replying!

      First thing the developers will need to know to investigate will be some steps to recreate the issue. Eg. Your config file now, and your config file & firmware version from when it worked (3.1.1?).

      There are many commands in your config that could impact this (e.g. M143, which IO port you're using etc).

        @Luke-sLaboratory Yes, I ran a pid tuning on everything since the new format seem to work much better and did improved stability.
        I gave more info in a response (not sure how to edit my post) about m307, how the bed is connected and which port it use. not sure if anything else is relevant.

          @engikeneer M143 is at 150.
          latest firmware used was 3.1.1 stable.
          it also happen on my other machines at least once, on hot ends. I disregarded as I was around and was busy so I just forced reset and get it going again.

            I know that sometimes the relay/SSR used can have unintended behaviors if not properly accounted for, they can "latch" on if too warm or if not properly configured. If you're able to provide part #'s for the relays and some pictures of wiring, etc, That could help evaluate the issue.

              well are you running in SBC mode or standalone for starters?

                    @jay_s_uk sadly SBC mode.. I know it isn't the most stable but it is the only effective way for us.

                      seems odd to invert an output
                      and you have no frequency set which means that SSR/relay would be running way faster than is good for it

                        Can you provide the contents of /var/logs/syslog for the day it happened on?
                        May be something of interest in there...

                          @jay_s_uk not a programmer here.. but I figure it is inverted because of the "!" ? Ill check that out.

                            Wait - this means that to have the bed be "off" - the duet needs to run with out3 "on"

                            so if the duet doesn't send signal (or if a wire gets cut, loose, etc) the relays will be turned on?

                            Otherwise, yeah, the frequency thing is definitely a non-recommended setup as well - Could @jrockland confirm that they're SSR's and not "traditional" relays?

                              @jrockland Yes - the ! is to invert the signal, in this case, for the duet to turn "on" the expected output, it needs to turn "off" the on-board output.

                                which definitely isn't very fail safe...

                                  those settings rre incorrect.find the correct beta value in the thermistor documentation.

                                      doesn't really matter in this case as its using an external relay

                                        @Veti Depending on the actual thermistors they could be, but having all 3 be identical is suspect for sure! - would need validation to be 100% sure. For relay outputs, any output is fine, I prefer to use a connectorized output for my SSR ones.

                                          B4138 thermistors have not been used in years. so its very unlikely that its correct.
