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.

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!

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

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

Being new to 3D printing, I have ran into stopped prints, due to laptop issues, way to many times, threw away too many long prints that stopped several hours into it, looked at so many videos that only confused me more. Found your video this morning, and you did an AMAZING job at explaining it in the simplest of ways to finally make me understand. Thank you very much for your help. Not only did you help me get that print back up and running, when my laptop had another issues, I was able to explain to my children how I was able to get it fixed, with your teachings. Very much appreciated!

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!!!

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!

[bagenius]

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.

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! 😁🎸

[darlenereed]

Thank you so 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!

[ad-mc]

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.

[prelunar]

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.

[NickCMOS]

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.

[MrKoky]

THIS VIDEO IS AWESOME!!! THE DETAILED EXPLANATION OF HOW TO EDIT THE GCODE IS GREATE!, I WAS GOING CRAZY TRYING TO FIGURE OUT HOW TO DO THIS AND NOT WASTE ANY MATERIAL EVERYTIME I GOT A FAILED PRINT AND THIS IS BEYOND A LIFE SAVER GREAT VIDEO, I LOVE IT THANKS FOR THE INFORMATION, VERY HELPFUL!

[MiLo-cuiv]

Super cool ! If I may ad, as a CNC programmer, it goes really slow when the program is launched again because the "F" in the Gcode is at 300, "F" is the speed, the line below is set as F9000, you could just rewrite the first F300 to F9000 and that should do it!

[MaxintRD]

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!

[MaxAethon]

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.

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.

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