      Dear All!

      Is there a way to continue bed heating after setting it to standby with M144, or to off by M140 S-273.15?

      The reprap gcode base states that M140 without parameters should just do that, but it does not seem to work, it rather reports the current bed temp.

        Looks like there isn't currently a way to resume bed heating without specifying the target temperature. I think the most logical way to resolve this would be to add a parameter to M144 to say whether you want to put the bed heater in standby mode or in active mode, with the default being standby for backwards compatibility.

              @dc42 I registered an account to look/ask this same question. I don't really want my filament sensor triggered pause to sit for hours with the bed and extruder at temp. I wish this would be an option such as M109 R2. I am very new to the Duet. I know Sbase has this as an option to shut off heaters during a pause in the config file. I am kind of surprised the duet doesn't have something like this.

              Thanks for all you you do DC42!

                I could see wanting to keep the heater active during a pause to prevent the print from detaching. What's less efficient, keeping the bed warm or toss a failed print?

                  M144 S1 will set the bed heater back to active in the next firmware release candidate.
