non uniform heat in software


Recommended Posts

Posted · non uniform heat in software

I have a bibo dual extruder, which is inputted into cura as a non network printer. Both nozzles are set to generic PLA which used to be set permanently to 200* although for some reason now when I save the file to a removable drive it sets the temperature of nozzle 2 to 175 degrees while nozzle 1 stays at 200 degrees. I checked the actual code and it says "M104 T1 S175" rather than the "M104  T1 S200" that I would expect. To fix this, I changed the 175 to 200 on lines 17 and 21, but it only allowed the pre heating to be 200 degrees. I couldn't find any other instances of the 175 so I don't know the cause. I have uninstalled every file related to cura, ended its task and done everything I can, I don't know what else to do.

    175 degrees is the standard "Standby temperature" for PLA. Cura uses the standby temperature to prevent oozing and material degradation by keeping the same material in the hotend.

    Thank you, but I thought this might be the case so I let it run until the nozzle would have been needed, but the temperature never raised, and the motor couldn't or just wouldn't push out the filament in the 175* nozzle. due to this, the support wasn't printed, and the model all got stuck to the one hot head (not a big deal, just to show that nozzle one worked as expected).

      • 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.
