Skirt and rafts

[Leggy 0]

Hi I’m some issues with skirt and rafts

please see pictures

As a guess i would say the bottom of the model is not flat.

Before and after slicing 

its flat at first

can you share the stl or cura project file?
Based on how its slicing it appears the model is very much not flat..

I’ve even moved the job through the bed to try and level it, but no change

Hi how do I do that

hi its in sketchup

The issue is with the model, it is very broken. That is causing issues with Cura when you are trying to slice it.

Any way of showing me, it looks fine in the design program 

[Dustin 160]

Cura should be telling you this.

That blue and green section is basically unknown geometry.
This will be a problem in how the model was designed.. or how it was exported to STL.

I don't use sketchup so not sure how to help there

I’ll redraw it again tomorrow 

thanks

Morning 

ok I sliced the model in half with a square plane, so that surface has to be flat, in cura it looks exactly the same , how can that be?

hi this is the latest one, if you click on the top or bottom surface all is selected

I get this in 5.2.1.  I'd say the bottom is flat as the skirt stays outboard now.  The sphere is gone though.

I took the sphere out

strange it’s ok on ideamaker and not cura

can any one slice it with another slicer to see if it’s only cura

 

[GregValiant 1,354]

PrusaSlicer  Looks to be near identical to the Cura slice I posted above.

So what is going on , i have an ender 3 printing from a ideamaker slice and its ok?

[GregValiant 1,354]

Post a new screenshot of the slice in Cura and what looks wrong to you.  I thought it looked good.

Here is your "Phone stand bowling 23.stl" in Mesh Mixer.  You can see what @Dustin is talking about.  It's that one piece.

 

This is a view from the other side with the Mesh Mixer Inspector turned on.

 

Here is the #23 model repaired by MS 3D Builder and sliced in Cura 5.2.1.  This looks good but the build plate side of the bowling ball won't come out very well.

 

Here is a project file with that early model.  I didn't pay a lot of attention to the settings other than I did adjust the Line Width to .45.

Check out the file without the sphere, does it change

im using a 0.6 nozzle with a line width of 0.8

[GregValiant 1,354]

0.6 nozzle at 0.8 Line Width and .3 Layer Height.  I thought it looked better at .7 Line Width.

Thanks for all your help, I’ll check it out tomorrow

Still the same, I tried to install mesh mixer but it never recognized my password , the same as fusion 

[GregValiant 1,354]

Here is a project file. My E3 Pro is the active printer.  It's the model without the bowling ball, .6 nozzle, .8 line width.

This is a Cura project file.  If you open it in IdeaMaker you will just get the model.

Here is an IdeaMaker project.  Remove the ".3mf" extension to open it in IdeaMaker.

 That last picture was wrong should be this one

simple solution no skirt

[GregValiant 1,354]

When the skirt cuts though the model like that then there is a gap between the model and the build plate.  Stiction will be a problem for the head.

Try setting the "Z" to -0.1mm or -0.2mm.

The rotation tool has a "lay flat" tool for models that are slightly tilted.  Ms 3D Builder has an equivalent "Settle" tool.
