Cancel specific objects during print

Posted · Cancel specific objects during print

No idea if anyone has suggested this already, but I would love to have some way to be able to top printing one or more objects in a multi-object print if they have failed somehow during the print.

Well, in theory comments could be placed in the gcode showing where different objects start, and the firmware could just skip gcode from the start-comment of such an object until it encounters a new start-comment for another object. But that would be a non-trivial change to the slicer and to the firmware.

    I was thinking along those lines. I fully appreciate that this is non-trivial, but it is nonetheless jolly useful.

    This would of course could break Marlin in a big way, but perhaps not so drastically. As it is, the whole gcode thing is a bit long in the tooth for 3D printing, but assuming that we want to stick with it, one could add some very simple features into the firmware to handle this.

    For example, bracketing each layer of each object with a start/end marker in comments as @ahoeben suggests. Standard firmware will simply ignore these comments, updated firmware will understand what they represent and could, upon receiving a custom gcode, simply skip to the next object on that layer.

    Of course each object will need label, which could be set and/or autogenerated in Cura.

    Maybe this is something for @Tinkergnome to play with?

    a) I agree this would be very useful!

    b) Can Cura stop the print after completing a layer and send new gcode for the remaining layers of the print, (without some failed objects)? (I realize this would still be a lot of work / UI / etc, but seems less hacky than what was discussed above.)

    c) If any of this works, maybe just being able to tell a print to stop/start at an arbitrary [Z] would put it in the user's hands.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
