Redgum bed plate visualization in CuraLE
Closed, ResolvedPublic


Currently the model of the Redgum build plate shows two wiper pad mounts instead of the auxiliary mount cover. We will need a new render and to update this prior to release.

@west If you can post an updated STL file here, I will take it from there.

@alexei Fixed bed plate location for quiver machines, and created a "redgum base" along with tying machine definitions to this in order to help ease of future updates.

Ready for review and merge

@west ,

4MB is a bit large, can you try to reduce the size of this STL? Preferably close to 1MB.

@karrad ,

Reassigning it back to you.

Just noting, 93% scale of STL file in X/Y to get proper sizing in Cura LE visulization

@west Any chance you can get a smaller bed plate STL?

The view I am getting on current build for positioning:




As you can see the buildplate STL model is smaller than CuraLE buldplate area, so yu shouldn't scale it 98%.

@alexei Some form of scaling will be required, I can try to get that closer that you highlighted.

This is the standard bed w/o scaling (not quite centered, but will highlight the issue)

The file cant be made smaller, FWIW the quiver bedplate is a larger file than the redgum plate

Could you try to play with tessellation settings in FreeCAD: Preferences->PartDesign->Shape View. To see if it woud reduce the filesize.
Also apparently @karrad was post-processing the file in blender, so make sure the origin of this STL file is lower-left corner, on the build surface.

Ideally we shouldn't post-process the STL file coming out from FreeCAD, because I think scaling factor might've been introduced by blender.

@alexei do you have an idea of the tessellation number to use ?

alexei added a comment.Jun 6 2019, 8:25 AM


Usually it's try and see process. I would start with increasing these numbers by x2.
Could you provide the link to the FreeCAD assembly file that you are using to generate this STL?

I did a fusion of all the parts, then created a mesh with 1.0mm Surface deviation and 30o Angular deviation and exported it to binary STL.
(2nd way described here:

The resulting file is 0.5MB

New smaller file and visual representation:

This was done by setting geometry to center of the STL file, and positioning by eye. I think this is good to merge.

@adam @west Can either of you check this branch build and let us know what you think visually?

adam added a comment.Jun 17 2019, 11:42 AM

visualization looks good to me

Merged to master.

My visualization is showing that the parts, when touching the build plate, are sunk into the visualization.
