The project file has everything profiles have but much more.
Hi @gr5 Has the project file all the visibility settings? Thanks!

Hi @nallath Attached is the project file. The modifer was centered on the bed. If you open it, you would find it moved a little. You can center it again and save it. Then you reopen it, the modifier goes away again. This is only one example. And the model names by the plugin Mesh Tools are also lost after reopening the project file.
Thank you!

If the whole layer containing bridging lines can be adjusted along with the bridging lines, the speed delay effect can be removed. But it seems to be impossible in the current version.
-
I come to understand the reason for the color change ---- the print speed change has some delay.
This lead to an issue ---- the bridge setting of lower speed would not affect the exact bridging range as much as expected.
Hope to know how you experts handle this situation. Thank you!

When I reopen a project file, either by "Always open as a project" or "Always import models", some modifier meshes are moved away from the saved position.To speak frankly, in using Cura, I'm always worrying about losing my work, because saving a project file is far from a reliable way of saving the whole work. I fully agree with others' comments on profile compatibility in another thread.This is really very dissapointing, and makes the software looking like being maintained by an open voluntary community but not a dependable company claiming "most advanced" or "most trusted".I know that you are ocuppied with improving the engine, but still hope that some very fundamental issues be fixed or improved.Thank you!

Is there any published systematic experimental data of the effect of nozzle temperature, flow rate and print speed on PLA bridging quality?Yes the practical effects might depened on materials and printers used, but the basic principles should be similar.Thank you!

No, that's not enough.
Hi @Smithy Thank you for your comments!

@GregValiant I attached STL in the last post, but ... lost...

That is a very odd result. The tree should grow from the build plate and not the part.

You can ty it with tree supports to see how it looks. Without support that roof won't print correctly.
Tree support seems to lead to odd result. Thank you!

Is there any better way to handle this situation? Thank you for your comments!

I don't know but I have a different technique - I don't use profiles.
Hi @gr5 I frequently backup the cura.cfg (C:\Users\xxx\AppData\Roaming\cura\4.8\cura.cfg). Is this safe for conserving all the settings (custom profiles, visibilities ...) when Cura is not upgraded?

I've a bridge wall crossing the length of 21mm. The speed seems to be odd.
Could you kindly give some clues on why the bridge wall is printed with varying speed. Thanks!

Switch to PrusaSlicer
Thank you! Recentlyy I just switched from Simplify3D to Cura. To get to be confident with all the settings of a new slicer is a painful process.

I know about Experimental > Enable Bridging Settings and all its options.
Below is a rea case of bridging
- Figure 1: before bridging
- Figure 2: bridging
- Figure 3: upper layer on the bridging layer (not set as Bridging Second Skin)
My question is:
Is it possible to make the bridging lines (Figure 2) go in the direction of its upper layer (Figure 3)?
If possible, most of the bridging lines would have shorter length.
Thank you!
-
In the preview mode, the bridging areas are displayed as Top/Bottom layers.
How can I know whether a yellow lines are bridging lines?
Thank you!

Existing models are lost:
- click/open an STL file
- commandl line "cura.exe aaa.stl"
Existing models are kept:
- menu/open an STL file
- drag/drop an STL file in Cura window
The issue makes it impossible to ADD a solid model from a modelling software directly to Cura.
I believe that the team should have noticed this. Hope it could be fixed. Thank you!

Hi @nallath Thank you for your comments! Yes, a raft can work for rought plate, but a big additional work.
The plate is not as rough as making the print fail, not bad to that extent. When I simply print the initial layers as dense infill with controlled density, it's ok. My plate is not too bad.

Why do you think that priting a solid bottom layer is a bad idea? it's the first time that i've heard anyone talk about it.
Hi @nallath Generally the build plate might have certain roughness, and very often I observe that the resulting initial solid bottom layer looks very rough (observed during print, somewhere overextrusion, somewhere underextrusion), even if I think that my settins for the initial layer should be ok. Yes I'm also curious about why other people didnot report this issue. Glad to have your comments on this. Thank you!
-
In my personal experience, printing a solid bottom layer directly on the build plate is often a bad idea. Generally I would set Initial Bottom Layers = 0 and print the initial 1~3 layers as infill of high density. I do this by adding a modifier block of the height of 1~3 initial layers.Is there a better way for the job without bothering to add a modifier block? Thank you for sharing your practice!
-
I noticed that, when Tree support is used, the setting Support Density is still availabe with the calculated value of 0.
What does Support Density mean for Tree support? The density of the branches?
Thank you for some clues!
