Feature Request - Target Flow Rate Toggle Versus Speed


Recommended Posts

Posted · Feature Request - Target Flow Rate Toggle Versus Speed

I'd like to see in Cura a toggle box that will automatically set speed based on a user input for a target flow rate. IE: Instead of setting a speed of 100mm/s at a line width of 0.5mm & a layer height of 0.2mm to get a target flow rate of 10mm3/s, being able to toggle a box to input 10mm3/s as a target flow rate with line with and layer height, and have it automatically calculate the print speed. Separate the parameter into the basic outer wall, inner wall, initial layer, etc.

Why this would be useful? In my workflow, I try to target a maximum flow rate for my printer to print as fast as reliably possible, as there's not significant difference between printing at stock settings versus a faster, tuned setting. I try to target between 8-10mm3/s because depending on the filament, that's the maximum my printer can reliably print at, but it's a little bit of a hassle to calculate speed values for parts of my print that require different line widths or layer heights, such as printing an inner wall at a greater line width, which requires slower speeds to meet my target flow rate. Having the target flow rate automatically adjust the speed would be very convenient. If this were implemented, I'd also like to see an integration with variable layer heights, so I can print the thinner layers faster, but still at my target flow rate.

This would also be useful for benchmarking flow rates for a printer, or more intuitively adjusting extrusion multiplier.

      • 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.
