why does Repetier-Host / slic3r invent a new part of my object ?

kaestnerw

Hello

I designed an object containing 2 wedding-rings. when I load it into repetierhost it looks like designed, after slicing there is on additional part in it. if I work with repetierHost V2.1.6 it invents a complete Part, if I work with Ver 2.2.4 it adds only in one layer a part which is not from.

I would like to add screen fotos but sorry I dont know how to add to this artivle.

Thanks for advice

hm strange I cant reproduce it. 
Could you share your slicer settings with me?

kaestnerw

Thank you for your work, of course I will send them.

I can make schreen-printouts of all 3 parameterfiles or is there another way to send them (f.e. copy data from the disk and send them) ?

Hello, I made Screen-copys of all parameterfiles - link: https://www.dropbox.com/s/bbar34uggouv4l9/slic3r_Parameter.pdf?dl=0

can you please look at them.

Thank you

Ok now I could reproduce it. 
It seems that there is a bug in Slic3r. Unfortunately, Slic3r seems discontinued, so I would recommend you to use PrusaSlicer instead. However, you can try to slice with layer height 0.2, there this error seems to not occur.

Thank you for your help, I willtry with 0,2 height.

Layerheight 0,25? Curious. Usually you should use 0,2 for faster Prints and 0,1 for finer Prints
