tree support missing some area

Hi @curasurf try changing the support X/Y distance

Here my support X/Y distance are 0.2 mm instead of 0.8 mm. And the minimum support X/Y distance is 0.1mm 

I also changed the support angle to 30 degrees.






Please let me know if this works for you!

Hi @fvrmr   It works. I was not aware that the X/Y distance has such a big effect. Thank you!


Sorry for another question (to simplify, I changed the support type to Normal and overhang angle to 60°)


How can I remove the steps and make the support contact the model 100% at the edge?


I tried to suppress it with settings below, but the steps persist:

            Support X/Y Distance = 0

            Minimum Support X/Y Distance = 0

            Support Stair Step Maxmum Slope Angle = 89°

    I am also having problems with Tree supports not supporting everything that needs support. I am attaching the project file, a 3mf of the design, and the gcode produced, but Cura 4.8.0 crashes whenever I output the project, so I don't know if it is valid, so I am including a screenshot of my support settings as well...

    There is a row of identical openings, only some of which get their top edge supported (ideally, I wouldn't want any of them to have support, the bridging of the printer is more than sufficient to handle this case, but I don't expect the support code to know that) and the angled opening on the side in the screenshots clearly requires support, but doesn't have any

    weirdly enough, it printed just fine with that 20 degree angle in the one rectangular hole. I guess my printer is tuned pretty well, at least
