    @Veti It is a commercial bed, reach 220c easy.. You are 100% right I will add an external safety switch in case.
    I was just really lucky because if it had been one of my hot end it would had catch in fire, and I'm not sure their is thermal fuse for that..

      @jrockland Get a fully spe'd and certified TCO from a reliable source like DigiKey. They only cost about $1.

        @engikeneer Duet3d 6HC, latest firmware 3.2 stable.
        config doesn't matter as it went into fault but kept running. not the first time since the firmware update.

          @mrehorstdmd TCO ? like those thermal fuse ? sound like a really good idea, and if they are small enough I could also stick one on top of my heat block. I will look into it.

              @Veti m307 h1 r0.310 c706.9 d6.34 s1.00. I don't know why you want that.
              I have to re type it by hand so I wont do the whole config file.

                we mean the whole config.g. you can copy and past the entire file. no need to retype

                    how do you expect anyone to analyse this problem if you provide no information?

                    i could state that for every other user this is working fine and must be a problem in your setup.

                      *** For developers:
                      -heat bed is ran by relays (First thing I checked was if a relay had "stick")
                      -firmware went into "fault" after it couldn't heat fast enough (happen often)
                      -instead of shutting down it kept feeding the relays.

                      -Did a M999 and everything went back to "normal".

                      Board: Duet6HC
                      Pin out: IO3.OUT
                      m307 h1 r0.310 c706.9 d6.34 s1.00
                      firmware 3.2 stable

                      never had this issue before last update.

                        The printer uses a Duet board but you don't have access via browser to the Duet Web Control?

                        That seems odd.

                          @fcwilt not from my computer. I need the geek squad to get on their computer for that.
                          also lot of information is confidential so I can only quick fix manually from the firmware user page and can't copy paste anything.

                            However - some explanation on why the config.g is useful here - it helps diagnose some other issues from weird or overriding settings.

                            Have you ran a new PID tune with the update to 3.2? The heater tuning uses feedforward algorithms to improve performance and may be one of the reasons for not heating fast enough.

                              @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).

                              E3D TC with D3Mini and Toolboards.
                              Home-built CoreXY, Duet Wifi, Chimera direct drive, 2x BMG, 300x300x300 build volume
                              i3 clone with a bunch of mods

                                @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?
