Start gcode from cura 3.6 to 4.2


Recommended Posts

Posted (edited) · Start gcode from cura 3.6 to 4.2

So I have been out of the cura game for a while, last used 3.6 and everything was fine.  I get the new cura 4.2 and use my same start gcode and my print starts (it seems to heat bed, waits till bed is heated, then does home of all axis fine, then starts heating extruder and when heated it just starts extruding and lcd says printing but it just starts extruding in the middle of the bed without any x, Y, or z movement.   Is it my start gcode? It seems to skip my whole prime and start wipe procedure and position and go right into printing but only extruder is moving in the center of the bed.  Any suggestions?

    For all those who care, I managed to fix it by putting in M105(report temperature in between/right before M190 and M109.    What I want to know is why everytime Cura changes versions do I have to change, delete, modify or otherwise add extra gcode?  Really screws you up and makes me not too keen to upgrade

    You don’t mention what printer you have, nor did you label in the listing the demarcation between Cura-generated gcode and your start code.


    However, I suspect this has more to to with a change to you printer’s firmware than Cura since it is your printer that executes the gcode.

      • 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.
