Hi!


After using S3D for almost two years I wanted to try out an a little more advanced slicer... CURA 3.6. 🙂

But with CURA I have extreme stringing and I don't know why.

 

I first noticed the problem when I wanted to print a fan duct for my HEVO printer and the inner travel area was full of blobs (fan_duct.jpg).
Then I tried to print this object: https://www.thingiverse.com/thing:2563909

 

The results were damn bad. 😞 Not much string between the two pillars but oozing filament during the moves (cura_result.jpg)


I played with the retraction distance (2.2mm to 4.8mm), the retraction speed (40mm/s to 100mm/s) and many other parameters but the result shown in "cura_result.jpg" is the best I got. Shortly before I wanted to throw the printer on the garbage, I printed the same object with S3D with mostly the same settings (2.2mm retraction @ 60mm/s, 70mm/s printing speed..) and I got got a nearly perfect result (left_cura__right_S3D.jpg <= the white objects! - made by a guy who has the same problem. My S3D result was better.)! O.o

 

Yesterday I deleted alle settings and profiles from Cura and started from scratch.... same results. 😞

What am I doing wrong?

Printer: Anet AM8 with DuetWifi2 board
Filament: PETG 1.75mm (DasFilament) printed at 230°C
Hotend: E3Dv6 (original) with 30cm bowden tube (cabricon)
Extruder: Bondtech BMG extruder
TravelSpeed: 160mm/s
Acceleration: 2000mm/s²
Printing speed: 70mm/s
Part fan @ 25%

Tested software: Cura 3.6.0 / Cura 4beta2 and Cura master (1st march 2019) / Simplify3D 4.1.1

      • 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 5.3.0-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.
