Geschwindigkeit Z-Achse?


Recommended Posts

Posted (edited) · Geschwindigkeit Z-Achse?


in Cura ab Version 4.2 gibt es neue Start-G-Codes.

So habe ich im Profil eine Zeile "M203 X500.00 Y500.00 Z10.00 E50.00"

Meine erste Frage ist, wozu soll diese Zeile sein?


Die Option "Maximum Z Speed" wurde durch "Sprunghöhe Z" ersetzt. Laut Erklärung soll die Geschwindigkeit, mit der bei Z-Sprüngen die vertikale Bewegung (Z-Achse) erfolgt.
Bei mir wird aber genau dieser Wert immer für die Z-Geschwindigkeit verwendet. Dumm ist, das man diese Option "Sprunghöhe Z" nur sieht wenn "Z-Sprung beim Einziehen" aktiviert ist. Ist dieser Punkt nicht aktiv wird die Option  "Sprunghöhe Z" zwar nicht angezeigt, aber der darin eingetragene Wert wird verwendet.
Ist dieser Wert höher als der in der Zeile ""M203 X500.00 Y500.00 Z5.00 E50.00 ;Setup machine max feedrate" eingetragene Wert, wird dieser nicht begrenzt, also ist die ganze Zeile dort obsolet. Trage ich in "Sprunghöhe Z" eine 0 ein wird ebenfalls nicht der Wert aus M203 verwendet obwohl dieser ja einen fehlenden Wert in der Firmware ersetzen soll.
Es wird dann bei jeder Z-Bewegung ein F0 in den G-Code geschrieben.
Hier haben sich die Programmierer wohl ins Knie geschossen. Ich bin mir sicher die wollten nur was gutes erreichen, ich habe gestern eine halbe Stunde gebraucht um rauszubekommen woher die Geschwindigkeit für die Z-Bewegung kommt. Darauf das ich erst einen Z-Hopp anstellen muß um die versteckte Option mit falscher Erklärung zu finden bin ich nicht gekommen.

      • 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.
