Start and End script


Recommended Posts

Posted · Start and End script

I've got a question about how the primming before print is done with the new Cura 2.3

I had an Ultimaker original with dual extrusion kit, and during this time with Cura 1.15, I was able to create a start and end script for single extrusion (wich primed only the first nozzle), and an alternative script for dual extrusion (wich primed the both extruders).

How does it work with Cura 2.3 ?

I saw that we are able to write a Start and End script, but what we have to do ? Prime the both ? Prime without T0 or T1 instruction a startup ?

I don't know. Could you help me please ?

    up ?

    I've got another question. I used the "ultimaker original + dual extrusion" start script. Which one which prime the second head then retract it to finally prime the first head (without retraction because of this head will be used immediatly).

    With Cura 1.15 it was perfect, because just before using the 2nd head, Cura generate the command G91 E0 to extrude the same amount it was retract in the start script.

    But in Cura 2, this command is missing ! So the filament stay retract and nothing is print before long long seconds. Could you tell me why this command was deleted.

    There are maybe a lots of good reasons, but in that case, could you tell me what is the best pratice with my dual extrusion printer (or with Ultimaker 3, because I think it's the same) to prime the both heads automatically ? and prime only the first head (or 2nd head) with a single extrusion print ?

    I don't know. The dual extrusion script never got a whole lot of love from us (I have to admit i'd be hard pressed to find a working UMO dual extrusion in the office)


    Come over and I show you :-) (ok, not perfect, but working... more or less...)

      • 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.
