"Angled faces arenot sliced properly. There are gaps between layers. Wider gaps as more close to horizontal."
That's the nature of FDM printing. The closer you get to horizontal the farther apart the "steps" between layers get. The formula is TAN(90-Angle) * Layer Height = Step Distance. When the step distance gets farther apart than your line width the model starts to fall apart into strings as the steps don't get glued together. It happens on that model because the surfaces have no thickness. On a regular model there would be material below to fill in the gaps. It would still need support though.
If you have a surface or overhanging feature that just happened to be 26.565° from horizontal and your layer height is 0.2mm then the formula says: TAN(63.435) * 0.2 = 0.4. If your line width happened to be 0.4 then you need support because the outside wall extrusions no longer touch the one below.
Your surfaces are infinitely thin. If Cura doesn't slice right along the plane of the horizontal surface it could be missed and you get what you see. If you play with the "Initial Layer Height" you may find a number that allows the horizontal surface to be sliced. It still won't print as the whole thing is over air and so it would need support.
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
