prusa-slicer - fail to slice a simple model

Dear all,

 I created quite a simple model with openscad.

However when trying to slice it with latest PrusaSlicer (Version: 2.1.0+win64
Build: PrusaSlicer-2.1.0+win64-201909160915) it fails.

 

I am using original presets and I am unclear why it finally fails.

 

The openscad-source-code:

 

//cr10 - ditan

 

 

//nema17 motor stuff
nema17_lochabstand=31;
nema17_radius=1.7;
nema17_seitenlaenge=42;
nema17_hull_radius=2;
nema17_boden_dicke=5;
nema_17_center_hole_dia=24;

//bottom_plate specifics
screw_enlarger_height=5;
screw_enlarger_radius=3.5;
3mm_screw_radius=1.45;

//ditan
ditan_orinal_srew_distance=67.5;
ditan_original_length=80;
ditan_original_height=20;
ditan_mount_thickness=4;
ditan_mount_height=55;
ditan_mount_height_cooling=12; // set to zero to disable
ditan_flatwasher=2.3;

 

 

module ditan_holes (radius) {
cylinder (r=radius,h= ditan_mount_thickness+screw_enlarger_height,$fn=32);
translate ([ditan_orinal_srew_distance,0,0]) cylinder (r=radius,h= ditan_mount_thickness+screw_enlarger_height,$fn=32);
}

module ditan_mount_eine_seite () {
height=ditan_mount_height+ditan_mount_height_cooling;
//cube ([ditan_mount_thickness,ditan_original_length,height]);
difference () {
union () {
translate ([ditan_original_length,0,0]) rotate ([0,0,90]) cube ([ditan_mount_thickness,ditan_original_length,height]);
//loecher_verstaerkung oben
translate ([(ditan_original_length-ditan_orinal_srew_distance)/2,0,height-ditan_original_height/2]) rotate ([-90,0,0]) ditan_holes (screw_enlarger_radius);
//loecher_verstaerkung unten
translate ([(ditan_original_length-ditan_orinal_srew_distance)/2,0,ditan_original_height/2]) rotate ([-90,0,0]) ditan_holes (screw_enlarger_radius);
}
//loecher
//oben
translate ([(ditan_original_length-ditan_orinal_srew_distance)/2,0,height-ditan_original_height/2]) rotate ([-90,0,0]) ditan_holes (3mm_screw_radius);
//unten
translate ([(ditan_original_length-ditan_orinal_srew_distance)/2,0,ditan_original_height/2]) rotate ([-90,0,0]) ditan_holes (3mm_screw_radius);
}
}

 

module ditan_mount () {
height=ditan_mount_height+ditan_mount_height_cooling;
color ("blue") ditan_mount_eine_seite ();
translate ([ditan_original_length,-ditan_original_length,0]) mirror ([1,0,0]) color ("green") rotate ([0,0,90]) ditan_mount_eine_seite ();
translate ([ditan_original_length,0,0]) cube ([ditan_mount_thickness,ditan_mount_thickness,ditan_mount_height+ditan_mount_height_cooling]);

}

ditan_mount ();

 

 

 

Kindly ask for help whats required to slice it successfully?

 

thanks

RE: prusa-slicer - fail to slice a simple model

could you zip and attach a copy of the STL for this model please?

Dear Joan,

 

thanks for helping. I created a "simpliefied" version if the STLslice_it_vertically_knob_at_lower.stl

 

You want to try slicing it this way:

 

 

thanks

@joantabb

And here is just another fail of the object. I hope the STL-files passed the upload.

 

many thanks

Dear Joan,

 

just adding the print-settings in case it makes a difference.

 

thanks

Hi Christian, 

Your STL is Faulty. 

loaded in Prusa Slicer as supplied

Loaded in slicer inverted

loaded in slicer turned 90 degrees

RE: prusa-slicer - fail to slice a simple model

when the same model is placed with it's large surface on the build plate, now gives a better but still defective result.

however if you use the Repair STL option

you  end up with a file in .obj format, which you can load into Prusa slicer, and get 

A working object... 🙂

RE: prusa-slicer - fail to slice a simple model

BUT you wouldn't normally print in that orientation, it would be more like this

as you can see the four holes are good on the Bottom side

And the 4 bosses, are good on the top side...

Forgive me slicing this with 4 outlines and Octogram Spiral top and bottom infill...   I was using them for one of My models, and just used the same settings for this example.

regards Joan

RE: prusa-slicer - fail to slice a simple model

Thanks Christian, 

the problem is not your slicer settings, there is an error, or errors in the STL file...   as described above!

@joantabb

Dear Joan,

 

first many thanks for your fast and very useful help. Based on your feeback I checked why my STL is faulty. I realized I had an outdated version of openscad to create the stl. Once I upgraded openscad to latest version slicing works nicely.

So all good now

Again many thanks for this quick help - appreciated
