The resurrect.g file is created when you pause the print, or (if you have configured the power fail action using M911) power is lost. It is deleted when a print completes, or when you cancel a print after pausing it.

If you want to perform a planned power down in the middle of a print, you should:

• Pause the print
• Set the active tool to standby or idle (but don't send M0, because that will cancel the print);
• Wait for the hot end too cool;
• Then turn off power.

My sole purpose for the print resurrect is to "rewind" the print to a specific point (typically the beginning of a specific layer) due to some reason (nozzle jam, filament tanglement, etc) and restart from that point.

My current problem is using this method:

1. When you detect the problem, pause the print. That will create a resurrect.g file.

2. Locate the point in the original GCode file where you want to resume the print from:

   Open the resurrect.g file in the System Editor and pick out the offset in the file where you paused the print. It's the long number in the S parameter of the M26 command.
   Open the gcode file you were printing in Notepad++, press control-G, in the popup box select "Offset", then enter the file offset. That should take you to the line where the print would resume from if you un-paused it. Now go back as many lines of the GCode file as you want until you find the position you want to restart it from, for example at the start of the previous layer change sequence.
   Place the cursor at the start of the line where you want to resume from, press control-G and select Offset again. The offset of that line will pre-populate the offset box.
   Edit that new offset into the M26 S parameter in resurrect.g.

3. Rename the resurrect.g file, because when you cancel the print it will be deleted!

4. After cancelling the print, rename it back to resurrect.g.

5. Then if you resurrect the print, it will restart from that point. Make sure you have set up your resurrect-prologue.g file first.

using that process always worked prior (ver-1.8ish) to upgrading to the newer firmware versions.

Now i can pause and restart prints just fine, but if i do the above, cancel the print and resurrect it using M98, the Z axis always goes somewhere other than that the Offset code in Notepad++ should dictate. For instance, i cancelled the last print at Z68.28 and did the process above with an offset that start at a previous layer height of Z57.48
My resurrect-prologue.g file is:

G28 XY ; 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

And the Resurrect.g file for the above scenario was:

; File "24in Nose Cone.gcode" resume print after print paused at 2018-12-24 11:16
M140 P0 S60.0

G0 F6000 X264.505 Y272.310
G0 F6000 Z68.280
G1 F600.1 P0
M24

When the print was resurrected, it homed X and Y properly, then start driving the Z axis well below the 57.48mm layer height setting (i finally had to hit the emergency stop as it began crashing into the print around 5-6mm below where it should of restarted printing.

The capability of restarting prints was one of the biggest reasons i chose the duet board and when this capability worked perfect right out of the box with the firmware version it was shipped with, i was extremely happy. Ever since the firmware updates though, that capability has been less and less likely to happen reliably..

The resurrect.g file contains a G0 Z command near the end, to resume printing from the point at which it was stopped. To use the technique you describe, you would need to either edit that command, or restart the print just before a G1 Z command in the SD card file.

The main change to the resurrect facility in recent firmware is that there is now a G92 command in resurrect.g just before the call to resurrect-prologue.g. That shouldn't make any difference if you home Z in resurrect-prologue.g.

David,
Thanks for taking the time to help work through all this. Here is the code directly at the "M26 S" offset number in the above resurrect.g

; layer 96, Z = 57.480 (this is offset #2524245)
; feature outer perimeter
; tool H0.600 W1.440
G1 Z57.480 F50

To make sure i'm understanding what your saying, instead of using the Offset # of 2524245, i should use the offset # Associated with the "G1 Z57.480 F50" line as shown above,
Or
I should modify the G0 F6000 Z68.280 line to show "G0 F6000 Z(insert start point Z height here)"?

@invertmast I've done pretty close to what you're talking about recently, but I didn't use the resurrect functionality. I have been using some stonefil filament that is very brittle and has a tendency to break mid print. I caught the break quickly and paused the print and canceled it. I found the layer height and edited the gcode file to remove all the layers before the one I wanted to restart at. I homed X and Y and sent M92 Z whatever to rehome since canceling the print turned off the motors. My Z axis doesn't drop when power removed so it doesn't need to be actually rehomed. I restarted the print with the edited gcode file, it did all the preamble warm up, moved to the proper z height, and restarted printing. I guess it never even occurred to me to use the resurrect function because I wanted to go back a bit rather than to where I paused it.

prior to the firmware upgrade it was a HUGE benefit to me. I would start a 14-16hr print and have to leave for whatever reason. I may of been gone 1 hour, or 6, but if it messed up, it was easy enough to rewind the print by just changing that Offset number. Now with the process seemingly have changed, it will be nice to be able to have that feature again.

I just lost 3 hours on the latest print due to the filament coming unspooled (i use 25kg spools and the spool holder is extremely friction free to allow the filament to come off easily, but occasionally it comes off over the spool ends and wraps around the rotation bar the spool is on and "kinks" causing it to get tangled and no longer move..im still trying to figure out how to fix this). If i would of been able to use the resurrect function, i would of only been out 30 minutes of print time... oh well. The joys and frustrations of a rapidly growing hobby and learning new things.

25kg spools

2 ways to maybe help with the filament coming off the edges of the spool. 1. Add a cardboard barrier to the spool to give it a much higher lip. 2. Lay a towel on top of the filament spool so that it drags across the inside of the spool weighing down the filament but not impeding rotation. Some industrial machines use plastic flaps or the like.

yea i know.. 25kg spools, i've gone through 1 in about 2 1/2 months, have 2 more 25kg spools a 15kg and a 10kg.... that doesn't even include all of the little 1kg ones i have. lol

thats kind of what i figured. Right now i have a trash can with some foam packaging sticking out shoved under the spool and its working.

I'll probly end up printing some sort of contraption to mount to the spool holder that will allow adjustable tensioning since i have some 10 and 15kg spools as well.

[Phaedrux]

I don't know if it will fit a 25kg spool, but maybe it can be scaled up.

actually i printed something like that originally but the weight of the spool proved to be to much for the extruder to roll the spool on the holder (it was support by 8 ball bearings and 3D printed parts). Currently i have 2 cups that slide over a 3/4" aluminum tube that makes the aluminum tube fit the spool holes nicely, the tube then has machined ends to adapt skateboard ball bearings to it, then it rests in a combination of G10 plate and 3D printed holders hung off the side of the machine. Its kind of crude, but works amazingly well (to well really.. lol). I'll have to post photo's of this monstrosity later on.

I don't have massive spools, but I also use a bearing hub to keep them rolling smoothly, and I had the same problem of over rotation and the filament coming off the edges and getting tangled. I added a reverse bowden tube that went from a block fixed to the printer frame and then to the extruder, but it wasn't actually attached to the extruder. This allowed a fair amount of filament to be unspooled into the PTFE tube and added a bit of friction as well.

There might be a picture of what I mean in the link in my signature.

i have a setup like that to! lol. Its dangling though and i have thought about moving the spool up the printer frame so the bowden tube actually hangs below the spool Centerline hoping that will straighten things out. My trashcan is working pretty well right now though. haha
