Hi Folks,
posting here and repetier sections.

Repetier-host 1.6.2 + slic3r 1.2.9

I'm attempting to print a microscope adaptor - essentially a tube with a flange and some fancy bits at the top.

Downloaded the part from thingyverse, prints just fine, but dimensions are off.

slice, adjust, make whole and go again...

except now the slicing does not work.... either the tube is filled in, or the support and part meld into each other with unexpected parting lines at the flange...

much weirdness.

same settings for slic3r on both parts.

things I've tried.

inverting the normals.

repair in netfabb basic

OBJ and STL

recalculating the normals. reversing the spiral, redoing from scratch with different approaches...


TBH, I suspect it's not a Slic3r thing... but I've run out of ideas to try...

my suggestion is to design the part yourself and give it dimensions you need thingyverse is ok for ideas but files iffy. What are you using to adjust those sizes you reslice?
