Would you please attach a 3mf with your object? This way the object will be scaled to your resolution.

I was not able to reproduce your issue with the current 1.42 slic3r alpha, when I just loaded and down scaled your object to fit the print bed. I suppose I would need to have your object scaled to some exact size to be able to reproduce your issue.

I will be happy to do that. What is a 3mf?

badger6 commented 5 years ago

closed by mistake.

bubnikv commented 5 years ago

file menu -> save will save a project file with the 3mf extension (the 3mf is a standard for three dee manufacturing file format)

I had deleted the files. I reconstructed the model and still got a bad slice from slic3r. but instead of angular facets, the center of the piece was missing. Also I found that by rotating the 3D file 90 degrees about the x axis, it would slice ok.

3mf file attached.

You still did not attach the 3mf. You may need to zip it to pass through github.

OK, i zipped it and posted it.

Thank you for your patience.

I checked the object in a 3D viewer with a cross-section tool. Here you see, that your model is not a single pieces. It looks like your CAD produced an invalid model.

On Windows 10, you may let the windows hosted Netfabb service fix your model directly from Slic3r from the object's context menu. On Windows 7, you may use the Netfabb service through the web browser.

We are working hard to make Slic3r robust to not quite valid objects, but there are always cases that our algorithms do not handle quite well.
