Resume long print

Recommended Posts

Posted · Resume long print


I had the first time experience to wake up to see a 25h print job abborted after about 21 hours :(

The printer just decided to be a dick and grind down filament (or the nozzle is clogged).

One half Yoda

I'd like to save this print. How would I go about it? I don't have the layer number where it stopped, but even if I had it, what to do?

Remove the actual print, start a new print with the upper half of the model and glue them together? Ideally I'd like to resume the print like it is. Right now I think I'd need to switch to gcode (not ultigcode) and remove the starting gcode. Then create a new object without the lower part and add a z move command so the bed moves down.

Is this the correct approach?

    Im sorry for you :(

    Would be cool to use the calibrate bed for this. So that you can move the head over the print and set the height.

    But then there is still the problem wich layer to start at. Also you only have one try, if you choose the wrong layer its over.

    I think start a new print of the upper half and then glue it is the best way to go.

    This way you can print one or two layers more and remove them with a rasp.

    Rubber grinding discs like this work awesome to clean up the model after gluing it. I had a blue one once, and it worked great, you couldnt see the line where it was glued afterwards.

    I would try http://gcode.ws to determine on which layer the print stopped. With the Yoda model at this height, it might be possible to determine even the exact layer when you see then in the viewer and compare it with the print.

    The follow-up would be to delete the already printed layers in your UltiGCode file (in a copy of it, actually ;) ) and add some 'G92 Ex.xxxx' command before 'first' layer. If the start procedure of the UM2 is likely to collide with the existing print, you may have to create a RepRap version of the gcode in order to safely control what the printer is doing.

    continuing resuming rescuing failed print

    First you need to use pronterface to find the exact layer to continue on. Pronterface is here:

    Alright, many thanks.

    I tried to resume the print, got the layer height right but the base model seems to have shifted over night. I abborted the print quickly and now I am printing only the top half and will try to glue it on.

    Well this didn't end well. The top half warped a bit (didn't use brim) and wasn't flush with the rest.

    I will weep softly, ditch the print and move on...

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
