[Not Manifold]

In case you don't trust Cura's analysis, here's what freecad thinks...

 

 

[Not Manifold]

 

 

Neither are manifold and so cannot be expected to print without problems.

 

[How to partially infill]

Hi, thanks for the model. Well, I sliced it using my normal settings and it looks OK, here's the last layer of the hole...

 

 

Here's the same model with the remove all holes setting enabled, perhaps you have done that?

 

 

 

[How to partially infill]

Hi, could you please attach the model file to this thread? Thanks.

[Not Manifold]

Could you please attach the stl file so it can be checked with another program? Thanks.

[Cura 4.6.1 - Can't get Top Surface Skin Speed option to appear]

Thanks for the file. I loaded that project, set top surface skin layers to 1 and then set the top surface skin speed to 20....

 

 

The speed is hidden unless the number of top surface skin layers is > 0.

Please save the project file (File -> Save) and attach to this thread so we can see the settings you are using. Thanks.

[Cura 4.6.1 Flow Rate Problems]

I doubt its the case but make sure volumetric is not on in cura, I believe the setting is called (RELETIVE EXTRUSION)

 

Relative extrusion has nothing to do with volumetric stuff. Equalize Filament Flow is closer in concept.

[starting points out of control!]

This looks like a long standing bug (not mine, honest!) that has been woken from its slumber by a recent change I made to the wall print ordering. I have a fix which I am testing and, if that goes well, will submit to be included in a future release. A workaround is to disable the wall order optimization.

[starting points out of control!]

Thanks for the file. I am investigating...

[Experimental Cura build for Raspberry Pi 4 now available]

I have managed to workaround the various limitations and bugs in the graphic library and now have quite a nice display. It still has some compromises compared to the other builds (Linux/Mac/Windows) and it's definitely a bit sluggish if the model is large but for small models I think it's preferable  to the compatibility mode display. YMMV.

Could you please save the project file (File -> Save) and attach the .3mf file to this thread? Thanks.

[Cura line size vs object size]

It only generates sufficient walls to fill the space. Unfortunately, at the present time, Cura doesn't handle the situation where there is not space for an even number of walls very well. This defect is well known and the UM devs are currently beavering away night and day to come up with a solution.

[Cura 4.6.1 not showing support structure in preview]

There was a recent change that made support render slightly transparent so maybe your graphics hw/sw has some problem with reduced alpha and just doesn't show anything?

 

[Cura 4.6.1 still has slicing problems]

Thanks for the file. The model isn't watertight so it's not surprising that it is missing pieces after slicing...

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

[Feature request: named parts in gcode comments]

BTW, if you have the mesh tools plugin installed, you can rename selected parts so that the mesh names make more sense. Just right click on the part and use the mesh tools portion of the context menu.

[Feature request: named parts in gcode comments]

Thanks for the file, I sliced it and then searched for MESH...

 

;MESH:ThreePartNameTest.3mf(2)

;MESH:ThreePartNameTest.3mf
;MESH:NONMESH

I have this installed, not sure I have ever actually used it.

["Select face to align to the build plate" doesn't quite align]

I think it looks right for you @burtoogle, because it might depend on where you exactly click when selecting the face.

 

Exactly! Look at all the faces it has to choose from. Can you guarantee that they are all aligned horizontally?

 

["Select face to align to the build plate" doesn't quite align]

I just got a failure when I selected a face on one of the short arms rather than the longer piece. Perhaps the arms are very slightly wonky (technical term) ?

["Select face to align to the build plate" doesn't quite align]

I tried it a couple of times and it worked OK for me.

[Feature request: named parts in gcode comments]

Cura and Octoprint already support this feature...

 

Look for ;MESH comments in the gcode.

 

[Cura line size vs object size]

Cura does lots of "tricks" but in this regard it is straightforward. The outer walls will be inset 1/2 of the line width from the outline of the object so, in theory, the object should have the correct outer dimensions. Of course, that assumes that the printer motion is perfect and the extruder calibrated, etc. so, in reality, it is normal for the object to come out slightly the wrong size and some tweaking may be necessary. This is FFF printing, after all.
