Resume a print after a power failure



  • Resume a print after a power failure

    Hi

    I am getting the following error when trying to restart a 22-hour of a 36 hours print.

    Error: Attempting to extrude with no tool selected.

    I call the resume print command M916

    It homes both the Y X also the bed heats back up to its pre-state temp, but the extruder does not heat up at all.

    I have the following in the files required.

    sys/config.g file

    ; Automatic power saving
    M911 S10 R11 P"M913 X0 Y0 G91 M83 G1 Z3 E-5 F1000"

    sys/resurrect-prologue.g

    M116 ; wait for temperatures
    G28 X Y ; home X and Y, hope that Z hasn't moved
    M83 ; relative extrusion
    G1 E4 F3600 ; undo the retraction that was done in the M911 power fail script

    sys/resume.g

    Any help please as to where this is not right that I need to correct so I don't lose this 22 hours of a 36 hours long print.

    Thank you

    @dc42 I followed your suggestion and corrected the T0 P0 then M116 before that G1 E4 command into the resurrect-prologue.g, and now I am getting the following errors.

    28/09/2019, 10:47:49: M98 P"0:/macros/Power loss resume": Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset. (this part is clear as it has not homed the Z to prevent crashing into the print)

    28/09/2019, 10:48:32: : Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

    The heater did not turn on, I know it works as I can turn it on by command in the WebUI, so there is not a fault on the heater

    Try adding G10 P0 S205 R205 then M116 before the G1 E4 command in resurrect-prologue.g, to wait for the tool to reach operating temperature.



  • Hi @dc42

    Do I leave the previous commands in that you posted beforehand?

    T0 P0
    M116

    so it now reads:

    sys\resurrect-prologue.g

    M116
    G28 X Y
    M83
    T0 P0
    M116
    G10 P0 S205 R205
    M116
    G1 E4 F3600

    M116
    G28 X Y
    M83
    T0 P0
    M116
    G10 P0 S205 R205
    M116
    G1 E4 F3600

    You can simplify it to:

    G28 X Y
    T0 P0
    G10 P0 S205 R205
    M116
    M83
    G1 E4 F3600
