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

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

G28 X Y
M83
T0 P0
M116
G10 P0 S205 R205

You can simplify it to:

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