UM-S5 ABS Printing / Chipped glass / elephant's foot

Posted · UM-S5 ABS Printing / Chipped glass / elephant's foot

I decided to print ABS (UM brand) with my S5+Air Manager for the first time and a 0.8mm AA core - Long story short, I was unable to get the parts to come off.

I woke up to a cooled off print surface. When the prints finally came off, despite being careful, they took large layers of glass with them.

 

I have been using Magigoo PA for everything and I used it with the ABS thinking that I would need all the help I can get. I think that doing that in combination with the printing temps (more on that ) contributed to the issue. The temperatures are based on the NFC profile and the air manager was set to keep the print volume at 35C.

 

These print had the first layer spread out creating an elephants foot effect.

needless to say, I tried to make other smaller prints with PVA this time and still had the elephants foot. However they were easier to remove.

 

I have been tweaking settings and have been able to get rid of the elephants foot just by decreasing the build plate temp to 70C. I train of thought is that if I have an enclosure, the trapped hot air (temp being contained) will help prevent warping and hence I do not need such hot build plate. 

 

I will post another screenshot of the tweaked settings for your guys info on what seems to be working at the moment.

      • 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.
