Object structure changes depending on the geometry, possibly Cura problem
Posted
· Object structure changes depending on the geometry, possibly Cura problem
There could be many things causing this and I'm not sure which it is, but a lot of the time you can get a better surface by slowing down.
Try printing 1/2 speed you are printing now to see what happens. The bowden tube tends to store pressure like a spring. So when the print head slows down, and the extruder slows down at a corner, the printer tends to overextrude approaching the corner and underextrude just past the corner. So this is one possible cause.
Another possibility is that even though you asked for 2mm walls, in certain areas with those holes running through the corners, Cura may have been confused about how to fit 5 passes around the holes and another 5 passes along the side. It usually handles this just fine - I've even asked for 100mm skin and it usually works fine. But still. Try another slicer. Possibly Cura 13.04 which has a completely different slicing engine (but mostly the same settings so there is almost no learning curve). Or kisslicer.
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.
