How to Resume an Unfinished/Failed 3D Print! (EASY FIX!) 

I had just had a print 27 hours in fail due to filament getting snagged and it not feeding. It was 84% done, and this thing is over 360g in. YOU ARE A LIFE SAVER. So beautifully explained, and shown. You are an angel Emily :)

I think you missed a very important step for some users, Cura uses absolute extrusion in defult, so if we dont use G92 to set the offset of the extruder, the printhead will move to the xyz axis of the first line of gcode and continuously extrude filaments until it reaches the extruder(E) distance, ending up with a huge huge blob. So what I did to fix this problem is to not delete everything in the printer startup gcode section, but to keep the 'G92 E0; Reset Extruder' line, and replace the E0 with whatever E distance you want it to continue from. so in my case was 942.12175, so I replace the E0 to E942.12175.

Dear Emily (singing like James Arthur) You just saved 8 hours of work for my Ender 3! Thank you for your videos! Life is getting simple after watching your channel

Beautifully explained! This is such a daunting thing to think about to someone with little or no experience with gcode. You made the subject so approachable. Love it!

Thank you, Emily the Engineer. I am extremely grateful. I was about 90% through a 3.5 day print job when I had an unexpected power loss. I was devastated. Fortunately, you took the time to post this video. Awesomeness! Thank you, thank you, thank you.

I had a 24+ hour print, at 84% the filament stopped itself and I was so done with printing since it was the 3rd time it was happening. This is a life saver, more people should see this. Thank you so much

THANK YOU, I was a little worried about digging around the gcode, but seeing that it is really this easy to go back to it, it made me very confident to continue printing. You are a life saver. The print happily continues and what remains is one little line. That's a sacrifice, I'm willing to make. Once again, thank you.

Thank you. Your instructions allowed me to restart a botched 4.5 day TPU print that was 75%completed. It was a glow filament that developed a clogged nozzle, which forced the filament out of my direct drive extruder, so it continued to feed, but out and onto the floor. You are a life saver. Thank you!!!

I usually just take the part off the bed, measure the part and just lower that measurement down into the bed in Cura, leaving what didn't print above the bed, and print. Then I'll weld them together after the print is done.

Great tutorial. Very well explained. Exactly what I need after getting my shirt caught in my printer 3 days into a Storm Trooper Helmet causing it to jam. I actually started the print again from the beginning, but now I know how to recover the failed print and any prints that fail in the future. It's nice to know that a failed print is not the end of the world anymore lol

I can't thank you enough for this. Had a clogged nozzle 3 days into a 4 day print on a tight deadline. This helped me rescue the print and carry on.

Big thanks! was just a 8hr print but the loss of the entire print was not worth scraping it and starting over. Viewed 3 other videos and you were very clear and to the point.

Thank you so much for this video. It not only helped me think straight but I really got to familiarize myself with the G28 command. For those people asking "What If I can't auto home because the print is too big?" I was able to find an open area at the top right of my print bed so I moved my print head over to that corner manually making sure there was enough clearance between the print head/gantry and the print then using pronterface send command: G28 Z ; This will auto home only Z. Now raise the z axis above the print, this time either through pronterface or your printers menu and send command: G2 XY; This will auto home x and y. Then follow the rest of the instructions in other tutorials to find the resume height and how to adjust your gcode. Good luck!

Emily, your video has been a life saver, as I was able to resume a print that failed due to a clogged nozzle. Almost can't tell where it resumed. Brilliant!

This was the most helpful video I have seen for this problem by FAR! I am so happy I found it because I was becoming so hopeless after three failures in my 16 hour print! THANK YOU!!

THANK YOU!!!!! Your video was clear, concise, and saved me HOURS of frustration. Great job!

Thank you so much!!!!! This helped me save my son’s 19 hour print. He was devastated when it failed and I’m so glad I watched this and was able to save it!

Hi Emily, thank you for sharing this. Your clear explanation about editing the gcode file was very helpful. It helped me to print the remaining 2mm of a print that was almost done when I ran out of filament. As I saw the end in coming I did memorize the current layer height. I first tried pausing the print, to then melt a new piece of filament onto the last bit of old. That failed. It broke and when pulling the end I made the nozzle jam and reset the printer. After handling all that it was your video that finally helped me to finish my print with only a tiny bit of layer shift on a still usable print. Thank you so much!

New sub! How have you never popped up in my searches when looking for info on 3d printing?! This was so easy to follow, thank you. I’m going to give this a try.

Your second technique(my preferred btw) worked perfectly! You totally saved me a couple hours in not having to re-print!! I saved this video just in case I needed it someday and low and behold that day was today lol. Thank you Emily!

Can't thank you enough! You've really recovered so many prints out there.

OMG.... You are an Angel. Thank you so much for this tutorial. I have thrown so many prints away because my new printer has resume but prints offset for some reason. So I just followed your steps and watching it now. Seems to be back on track. Your AWESOME!!!. :D

OMG, you saved a print that I was 20 hours and 37 mins into. I watched several other videos, and they were not as easy as you made it! Thanks!

You saved my 16 hour print. Thank you. My octoprint just disconnected for who knows why... And I thought i have to restart then and there. So thank you again you are a life saver :D

I can’t thank you enough! Had a print on 5 days and a few hours with a few hours left and ran out of PLA, I thought I was SOL, and it’s now completed without restarting thanks to you!!

Being a cnc operator, I've done this after a tool break or change it is basically the same thing. Good video as always. Definitely want to see you time at the premiere. God bless

Omg, I had just started watching your awesome silly videos a week ago, and subscribed! Coincidentally, I came back to you today because of a failed jumbo axolotl I was printing! I am so thankful for this video, and I am currently trying it! Will update if it works :D

Love the video worked out pretty good first time ever 3D printing last night and followed your steps it came out pretty well

Thank you for this video, helped a ton and was very informative, ive watched so many videos like these and they just completely gloss over how to edit the gcode

One extra little consideration. If you set your fan speed differently for the first layer (ex: 0% on first layer and ramps up to 100% by 5th layer), then you need to retain the fan speed command since this may be deleted if you highlight everything shown in the video. Just search for the text "M106" and you should find multiple "M106 Sxxx" where the "x"s are numbers. Copy the last M106 command (the one with the largest Sxxx number) and insert it somewhere at the beginning of the gcode.

Thank you very much, Emily. You saved my 3D print. I’m recommending your channel here in Brazil.

It worked for the most part. I used calipers to get the layer height and divided that by the layer height. Everything was working but since it has cooled down and reheated it lost it's adhesion. The slightest bump and it got missed aligned. But, no fault of your instructions which were spot on. I have an Ultimaker 2+ and I didn't need to adjust the bed height as the job just resumed to the correct z-axis. I ended up just printing the rest separately and I'll attempt to glue it together and then sand. Wish me luck and thanks for your help. I'm sure to use this method. ❤️

Thank you so much Emily! I was using that boring method of print the other half of the piece then gluie the pieces together. Thanks to your video now i can save my print!

Vert well explained! So much better than so many other videos! :)

You are a lifesaver! Subbed! Easy to understand & concise!

Hey! I was printing a ukulele and it was about 80% done. It already took over a day to print and it failed. This video let me save it! I’m going to give it to my music teacher. You rock! 😁🎸

Exactly what I needed to save my 29 of 38 hour Iron Man MK2 helmet print.... thank you Emily... you and Frankly are what keep me going in this hobby. Be well my online friend.

Wife started 3D printing, ran into this issue, easy to follow and quick ! TYVM, subbed (:

THANK YOU! Even though my project is for a CNC machine, your information helped me more than you know! THANK YOU!!!!!!

Thank you for explaining it so well! I resumed my print without any problems. Awesome!

Thank you, thank you, thank you for making this video. I am a true now this when it comes to 3D printing and I'm super glad that you have this video out there for everybody to look at. I was into day one of my 1-day and 15-hour print. When I knew that I was going to run out of filament and I didn't have the correct color to continue. So I found the right color waited two days to get it while my print was on the heated head for 2 days and as of this moment it is resuming the print exactly the way that you talk us. Again thank you so very much. One of the questions I did have there was a g92 code and I believe I removed it because I felt like it would give me a problem and I won't know if it did or get because I was lol. Regardless thank you so much again!!!

Hail to the queen Emily, first of her name, savior of failed 3d printing! Long life to the queen!

You’re really the goat fr. I wasn’t understanding it at all until I found this video, and now I’m back in business lmao. Sheesh this was stressful😂

Good info. I appreciate your time spent creating this tutorial.

Love the videos Emily!

IT HELPS me alot, I was stuck in a middle of a print and now YOU save me with it

Emily, thank you. You saved me roughly 11 hours. I am grateful.

I know this was posted 1 year ago but this has been the best tutorial about this issue on youtube.

YESS you saved my SUPER long print that jammed like 8h in. THANK YOU. Your explanation was so simple I was able to understand how to do this.

thank you for savin' my print you deserve a subscribe!

Much easier than I thought. Thanks a lot, that saved me a lot of trouble.

My 6hr print stop had a nozzle clog and just did exactly what you did and I saved my print. Thanks

Thanks Emily! Keep up the good work!

Very helpful and easy to follow, thank you, you saved me a lot of time

Regarding the layer shift - I saw another video that suggested that may be caused because you're starting at a height that's already been printed, so the ridge is just extra plastic. In your case, since you probably sand everything anyway, it's probably better to get a good "stick" to the previous print and deal with the ridge. And anyone who tinkers with Gcode often might consider getting Notepad++. It's a little easier to work in, IMO. Thanks for a great video.

Hi, thank you so much for this amazing tip!! , never knew it was this easy , just saved me a lot of time money and filament lol

worked like a charm, I'm using a modded ender 3 max, the code is a little different for the start up, but this worked perfectly, thank you for saving my 22 hour print

Decided to check this out after a 35 hour fail. Will definitely do this in the future! Thanks.

Thank you so much for this!! You saved a lot oof time and money!

Really helpful thank you.Just started 3d printing and need all the help I can get.

Very grateful for this helpful video. My gcode file used absolute extruded positions, so it started squirting filament everywhere when the start of my file defined it to zero and the first subsequent extrusion command was 6000 or something like that. I stopped it quickly and set the initial extruder position to the one listed at the layer height I was resuming from. That seems to have worked. Thank you!

Nice tutorial! I need to try this next time!

Thank you so much!!! This was so easy to follow.

YOU SAVE MY DAY AND MY WORK..!!!!! One more suscriber...!!! very very good job Emily!!!!

Appreciate it. This saved my senior design project

Worked perfectly for me, the only addional step i had to do was ajust the z offset, because it started wacking it, and i reajusted it every 2 layers. Awesome thanks.

Really terrific idea! This will save a lot of time and PLA . Thanks for showing us this!

This is better explained than CNC Kitchen's video, I just came from there super confused. So thanks for the help and the great video!

this was amazing! thank you so much emily (you are gorgeous and a queen btw)

Thank you so much, you are a lifesaver! Thankfully the layer shift wasn't that bad. New subscriber o/

I love you! THANK YOU SO MUCH! This saved my print!

Thank you i am a beginner 3d printer and this would have been my first all night print until, just before i went to bed i found that the filament had snagged and the printer had been printing for like 20 minutes without filament being fed in. Thanks this saved me like $5 of filament that i would have had to use to reprint it. Great tutorial ive decided to subscribe 👍 Edit: another failed print so now i gotta do it again

OMG I have a a print running for 22 hours and the filament snagged. I just asked my wife I wonder if there is a way to continue and boom your video popped up. Thank you so much for saving me more wasted time and money.😊

U are amazing!! You saved me $40 and 30+ hours into my 52 in print…also I have auto resume on my sidewinder x1 but it resumed in the air way away from model

This was great! The resume print for my i3 Mega S does not work, so your video came in clutch. Thank you!

Thanks Emily, I just started with 3D printing with an ender 5 pro. I had twice an issue that the print was not completed. For the printer it was but I think it was a feeding problem. The filament got stuck in the guidance tube. Don’t know why yet as the print was completed for 80 procent. But with this help at least I solved the feed issue again and can complete the job🎉

I just had a print fail because filament got tangled up. This was very informative. I didn’t have to start over!Thank you!!

You're so funny the whole video Maki sure people understand the method!! 👏

You saved my very first 3-D print! Thank you so much

Very cool video and it helped me out a lot! Thank you for sharing this was great!

That was easier then what others said, thanks, I didn't have a huge print, but it was a 3day one and this was so simple

you are a life saver, worked perfect for ender 5 plus

Fantastic job!!!

OMG!!!! Thank You So Much!!! I LOVE YOU!!!! I think you, Franklybuilt and Crashworks should come together and open a 3D printing academy! I would literally pay to take online classes from you guys!

You are amazing. Thank you for this tutorial!

Hi Emily, FYI, your printer starts up with a very slow "default speed". If you want to change the speed, you need to send an "Fxxxx" with the move-Gcode. The standard slicer output contains that somewhere or even regularly (if it needs to change speed a lot). So just look for "Fxxxx commands, pick one of the highest numbers and use that. Your printer is probably capable of doing that speed. Or, as you did.. .just wait it out... :-)

Very cleaver! Liked and subbed! Thanks

Notepad isn’t good at handling large files, so if anyone has a super large gcode file, using a professional text editor like UltraEdit, Visual Studio or any text editor you find useful will resolve the issue. If not, try another until it doesn’t crash or lockup the editor’s process. Also, depending on your computer’s global settings, saving a file with another extension besides txt, still lead to a file with txt on the end of what you chose. First of all, if your explorer settings are set to “hide extensions of known file types” then it can mislead you to believe you have an extension other than the true value. Turn that setting off and then use rename if you see something that isn’t supposed to be there. Great video to the OP, you just taught a career software engineer something.

Thank you for this video. Now I can try with different filament colors.

i think you saved me hours of work haha thank you!!

Great explanation, amazing!

OH MY GOSH THANK YOU THIS HELPED SO MUCH

Found this video for just this reason.. Had a filment snag. Great fix err work around for this issue.. Wish there was a sensor, you slide on for filment feeds, that would automatically pause if there was no movement... Great Video very helpful.... knee 2... Funny I have 2-3-4 on all my save as files.

You just gain 1 subscriber! thank you so much!

thank you so much, just had a 15 hr print fail, no more reprinting entire fail prints that may arise

thank you so much! It worked on my Ender 3 perfectly!

This is AWESOME information!!!!! THANK YOU!!!!!!!!!!!!!!!!

Nice video ! 👍

Thank you so much! It’s midnight and my silly butt clicked stop print instead of pause. Your tutorial made navigating G code so easy.

Thank you for sharing!!
