Retaining nozzle and bed temp settings after printing is done

Posted · Retaining nozzle and bed temp settings after printing is done

Is it possible to set Cura default settings to retain the nozzle and bed temps when printing is finished? 

 

I want to go on with printing another object but the GCode sets the nozzle and bed temps back to zero.  Also, I have to manually adjust the bed temp back to 60C to get the object to release from the bed.

 

I'm using Cura 4.13.0 and a Ender 5 Plus.

    There are a couple of lines in your End Gcode that shut off the fan, the bed, the hot end, and disable the steppers.

    You can set "hard" numbers or you can set Cura keywords.

    Go to "Settings | Printer | Manage Printers | Machine Settings" and in the bottom right of the dialog is your End Gcode.  There will be lines:

    M104 S0 (shut off the hot end)

    M140 S0 (shut off the bed)

    M107 (or M106 S0.  Either will turn off the layer cooling fan)

    M84 X Y E (disable all steppers but Z)  This command will cause X Y E to lose their location information.  As long as there is a G28 at the start of the next file it shouldn't matter.  Not disabling Z keeps be X beam (or the bed) from drifting downward into the print.

    Adding a semi-colon in front changes a line from a command into a comment that the printer will ignore.  You can change them to:

    ;M104 S0 (Cura will ignore the line since it is now a comment.)

    M140 S60 (hard number that the printer will respond to and set the bed to 60°)

    M106 S0  (turn off the layer cooling fan)

    M84 X Y E (disable stepper motors.  If you put in M84 S1800 then the steppers will remain active for 1800 seconds (30 minutes)

    The line for the bed could also be:

    M140 S{material_bed_temperature_layer_0}

    That would maintain the bed temperature at whatever it was for the print.  A semi-colon would just comment it out.

     

    Understand that doing it that way means it will stay on forever unless you physically turn the machine off.  Don't forget.
