      Hello,
      I believe this is a quite simple problem but I can't seem to find a solution on my own...

      When I'm homing an axis with my hotend heated, the temperature starts to drop until the homing is done, it looks like while the homing macro is running, the heater turns off. But it's not showing as off in the WebControl !

      Any idea on what to do ?

      Thanks

        Does your M558 command have a B1 parameter? That would turn off the heater temporarily while probing.

          Indeed it has B1 at the end of the line. I removed it, I'll try tomorow but if it is supposed to turn of the heater when probing, now it should be working properly 🙂

          Thanks !

            Some probes work best with the heaters off during probing to avoid interference.

              In particular, some bed heaters generate enough magnetic field to affect a BLTouch.

                sorry for the late response !
                Removing B1 worked perfectly !

                Well that's a problem...I read this thread https://forum.duet3d.com/topic/8690/keep-hotend-off-until-after-bltouch-finishes-bed-leveling/6 and read a little more on the subject, I'm going to stick with B1 🙂
