HOW TO: Resume a failed 3D print!

It can be horribly frustrating if a 3D print that has already been going on for hours or even days fails and the printhead only moves in mid-air without printing anything. In this video, I’ll show you how you can easily resume one of these failed prints and save you a lot of time and money! Let’s find out more!

NOTE: This video covers the approach that works very well with GCode from PrusaSlicer and relative extrusions. If you're using CURA and notice that your slicer spits out absolute extrusion amounts (M82) then check the website article. The process of editing your G-code file might be slightly different!

I've kept hold of several large-ish failed prints, now having seen this, I think I can save some of them, and I no longer fear the dreaded air printing.
Super useful vid Stefan, thank you so much.

Lmao I love the “word is not a text editor”

[Peter_Schluss-Mit-Lustig]

0:02 i think even people who don't speak german can understand perfectly what you said

[gentiligiuliano]

I'm alwaya asking myself why It was never included to the fismware some function to "rewind" gcode until you can visually see it touching the print. It would be super handy.

I knew I would need this one day. Thanks a ton, man! You saved my 22 hour print.

Resuming a failed 3D print - worth the hassle or just dump and re-print it?

The only thing i would like to add to this, is a lot of times i have resumed prints i needed to add in a G92 E*** where *'s are a number close to the next extrusion. otherwise the printer will reject the GCode because it thinks you are trying to do a massive extrude (from E0 to E1000 for example). setting it to the nearest rounded down number allows the printer to continue printing!

Stefan, I have been watching your videos for quite some time now and I have to day that you are one of the best content creators out there for 3D printing enthusiasts. You have a great balance of fun things, as well as MANY things that are incredibly helpful. Keep doing what you are doing, my friend. YOU ROCK

[wecreatedit]

Never thought it was possible to recover a print like that. Genius. Thanks for the useful information as always. You make one of the most essential and best channels for 3D printing!

[henninghoefer]

If you delete "everything up to the G28", make sure there isn't a G29 somewhere before that, as bed probing pretty much certainly crashes into your unfinished print...

[tinkerershaven]

As always, you are one of the best in the 3D printing community and probably the one who got me the most into it, Stefan. Your videos are always awesome and super helpful! Keep it up!

One of the best 3d printing resources on the internet!

About a week after you posted the video on converting a to the duet 3 mini wifi my Rambo control board heated it’s last bed. Followed your super clear tutorial and resurrected the ol pig in no time.

Thank you for continuing to share your wealth of knowledge with the community!

[aivkara]

Thank you Stefan!!! One of the most useful videos I've seen about 3d-printing in the last 10 years. I can't even remember how many failed prints I could not recover.

[noanyobiseniss]

I just had a thought on resuming failed prints that you have moved on the bed. Print one layer on bed then place part ontop and resume either where left off or breakpoint minus 1 layer depending. :)

[hudali]

This is the best and most helpful video I've seen in recovering chopped prints. Very well done, sir. You are the best

[PortalFPV]

Great piece of content that should be a 3Dprinting 101 for anyone owning a printer

[jmonteschio]

I don't own a 3D printer, but I've watched a ton of videos because I want to get one someday. And I have to say this is one of the top videos I've watched. Nice job! I'm sure a lot of makers will be using your methods to save failed printer.

[algisneblett]

Thank you for this detailed guide on saving valuable printings in terms of time and material, sometimes having a big failed print feels so frustrating and this gives one a last chance not to let this lost.

[maxthoraxII]

The amount of times I've come back to this video... Thank you so much and I hope this continues to help others!

Make sure to also remove any wiping maneuvers and other moves if they move into the print area. Some code drag the nozzle from an edge all the way to center and that can be catastriphic.
