  1. Hi @nallath @ahoeben Thank you both!
  2. I have several custom profiles with different Support Overhang Angle. When I switch profiles, the overhang red mark does not update immediately. To force it update, I need to modify the Support Overhang Angle to a new value. It would be great if the overhang red mark would update automatically after switching custom profiles. Thanks!
  3. Hi @curasurf That's correct! Hi @fvrmr My test seems to suggest that that's wrong. In the mode of adaptive layers, Infill Layer Thickness seems to be is always a fixed times of the transient layer height, but NOT rounded to be a multiple of the transient layer height. Are you sure? For example, Layer Height (set, fixed) = 0.2mm Infill Layer Thickness (set, fixed) = 0.5mm ROUND(0.5/0.2, 0)=3 When the transient layer height is 0.3mm, the transient Infill Layer Thickness = 0.3mm×3 = 0.9
  4. Could you experts tell me in what language the formulas are defined in fdmprinter.def and other .cfg files? Python? Thank you!
  5. Topography Size is adjusted often. The smaller Topography Size, the better quality, the smaller layer height, the longer printing time.
  6. Until now, when I use S3D (and many other STL-handing tools) to import STL files exported from some CAD software, I never found the STL models displaced. This seems to mean that for most STL files exported by most CAD softwares, the position and orientation can be handled correctly. There might be something wrong for STL models exported by 10% (?) CAD softwares. But if it's OK for 90% STL models, it's seems be wortwhile to do something.
  7. In my understanding, 1. Layer Height ± Maximum Variation The range of layer height need to be defiine according to the overhang condition of a model 2. Variation Step Size This is only for the transition of different layer heights. It can simply be set at the default value. 3. Topography Size This is the key setting. It means the distance at which every two neighboring layers are shifted from each other in the X/Y plane. It determines the quality of all the overhang walls. The smaller Topography Size, the better quality, the smaller layer he
  8. I tried to calibrate settings for printing overhang walls and found something difficult to understand. At Layer Height = 0.2 and Line Width = 0.4, the LARGER Top/Bottom Layers value is, solid layers would appear along tilt walls of LOWER overhang angle. Could you kindly explain how Cura engine handles this? Hope I made the question clear enough. Thank you! overhang.3mf
  9. I'm sorry to say it's problematic for me to access github. Thanks
  10. In my understanding, STL does have a definite 0,0,0 point. I suggest Cura add a button to "restore" the original "postion" and "transformation" of STL models. All the information is there, amd what need to be done is adpating it to the buildplate coordinate system. This would definitely make many new users easier to start their Cura journey.
  11. After I get enough understanding of exactly how Adaptive Layers works, it became almost immediately indispensable for me --- only this one funcionality is enough to make Cura the ONLY slicer for FDM. It seems to be odd that there are very few discussions about adaptive layers and it's still put in the experimental section. I wonder how many people use adaptive layers in their daily printing jobs. Thanks a lot for sharing!
  12. No why. That is the way Cura works. In most cases Cura simply forgets the absolute position in a stl file. Fortunately, the function Merge Models can restore the relative positions of several models imported from different stl files.
  13. In my models, I generally need to set Top/Bottom Layers = 3 to make the overhang walls to be without gaps. But I don't need the topmost solid layers, and hope the models to be open at the top with infill stucture exposed. I tried using a modifier mesh and set it to Top/Bottom Layers=0, but new solid layers would be generatated immediately below the modifier mesh. Is there any workround or trick to replace the topmost solid layers with infill? Is it possible to add a post-processing script to simply stop printing upon starting to print the topmost solid layer
  14. To speark frankly, sometimes it's really painful to read these color schemes. The color bar is really too short and too crowded. Hope it can be improved. Thanks!
