Use a smaller layer height or perhaps even try the adaptive layers feature?

Hi, I'm afraid the model has errors, it's not watertight. Install the cura mesh tools plugin to get warnings about bad models.

Hi @kayazuki, I think there is a problem with the Cura concentric fill that I have fixed in my releases. [edit - this is actually in 4.6.0 but there is also a regression in that release that could be causing those jaggies]
You can find my releases at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0
They can be installed alongside the UM releases, please read the README.md file there before using.
That last gap can be filled if you enable the gap filling but, again, the UM releases are buggy and my releases have a more reliable gap filling implementation.

All you need to do is increase the value of skin removal width, 3 is OK...

Please save the project file (File -> Save) and attach the .3mf file to this thread, thanks.

Hi, thanks for the file. As far as I can tell looking at it, the only real problem is that it is doing a lot of travel moves while printing the skins. This can be avoided by using the zigzag skin pattern rather than lines pattern.

Could you please provide a sample of the gcode that has this problem? Thanks

Hi, could you please provide some example gcode that shows this problem, thanks?

Looking at your gcode, I see this sequence at the end...
;TIME_ELAPSED:3303.171209 G1 F2100 E3811.3849 M140 S0 M107 G91 G1 E-1 G0 X0 Y200 M104 S0 G90 G92 E0 M140 S0 M84 M104 S0 M140 S0 M84 M82 ;absolute extrusion mode M104 S0 ;End of GcodeThe G91 is setting the X/Y moves to relative and so the following G0 X0 Y200 may well be asking for a move off the build plate. Furthermore, the G1 E-1 is not going to work right either as the extruder is still in absolute mode. Perhaps you should have M83 rather than G91 ?

What value is the skin overlap? Maybe you need to increase it?

This is very interesting, what kind of printer is this?
That was printed on a Sovol SV01.
-
I printed that model with good results. I used a line width of 0.4mm and 10% skin overlap and, of course, the bridge settings enabled. It didn't drop any of the first bridge skin lines.
Here's the first bridge layer...

I imported your STL into FreeCAD and it agrees with Cura WRT the bounding box...

Thanks for the file, interesting model!
Cura's time estimation takes into account the print speeds but also the acceleration and jerk. You haven't enabled the control of acceleration and jerk so I guess Cura is assuming that your printer is using similar values to Cura's defaults. If your printer is actually using lower values for acceleration and jerk than Cura's default values, it will take longer to print than Cura's estimate. The values that Cura will be using are shown below.

As I said, the model is to blame, the blue/purple areas are bad (new Cura feature, not yet released) and the mesh tools plugin (available from the marketplace) tells you what is wrong, the model is not watertight, i.e. the edges of the polygons don't meet up exactly. You need to make the model watertight to ensure it is printable.

Without any further info, it's hard to say what is causing the issue. Please save a project file (File -> Save) and attach the .3mf file to this thread. Thanks.
-
Almost certainly, the model is to blame, the internet is awash with broken models. Please attach the STL file.
-
Export just includes the model(s) but Save includes the models and the settings. I have requested that UM alter that menu to make it more obvious but they weren't interested.
Anyway, when I slice your project I don't see so many direct travels as your image shows, what version of Cura are you using?
-
No dingbat, that's still not right. You did File -> Export but you have to do File -> Save.
-
No, that isn't a .3mf file, that's the gcode. Please do File -> Save !!!!!

Hi, please save the project file (File -> Save) and attach the .3mf file to this thread so we can see what settings you are using. Thanks.

I am not aware of anything in Cura to fix that problem but maybe some other tool can help. It's not my area of expertise but I think, in general, one has to go back and edit the model to fix issues like this.
