Hello everyone.
Last night when i was starting a new print, i noticed that the printer made some strange moves during the printing of the brim.
In my opinion, this moves are completely unnecesary, and i dont understand why slic3r does them. I have never noticed them before.
You can see them on the attached images.
I have tried several objects, but it generates those strange patterns on every brim/skirt.
And the thing is that those patterna makes my printer act realy strange. It sort of pushing those patterns outwards until it pops right of the mirror.
One patters in triangular, and the other one is just an empty tiny tiny line. Both always appear on all atempts to print.
I have tried to reinstall both repetier and slic3r, and removed all files in appdata manualy. But it still generates those strange patterns.
Are those normal? If they are, there must be somethings strange going on with my printer
as for your second “pattern”, the empty lines - that’s just the point where the nozzle changes from one brim line to the next, which is indicated by the cyan “non-printing move” lines. It also looks like you have Z lift activated, right?
The first pattern is a bit more complicated. The error is minimal on the first brim line and growing with further distance from the perimeter. So, it could be a multiplying rounding error due to the discontinuity at the corner of the (polygonal) perimeter. Or the stl file may have a tiny additional facet there, which Slic3r tries to take into account when generating the brim. You can upload the file to a free hosting site and post a link for a quick check if you want.
Hi Kuraasu.
I have tried to print an ordinary box.
In that scenario it should just make a square brim. But it adds this strange pattern even then.
So i dont think its connected to a specific stl.
But i would be thankful if you take a look at the file, as you said
I did not not create it. I found it on thingiverse.
the object isn’t manifold (among other errors), and Slic3r doesn’t like that at all (GIGO …).
Netfabb was able to repair the faults at least to some extent, which is visible immediately after slicing the object. However, Repetier notes over 60 intersecting facets for both versions, repaired and original, so there might be more trouble hidden somewhere.
The repaired stl (Netfabb basic, free version) should be printable with Slic3r as far as I can tell. Apart from that, some users have reported that Cura can slice stls with a few errors, so you could try that as well.
Something else caught my eye: the object is only about 32 mm in diameter, with the outer ring being less than 2 mm wide. You have six perimeter lines plus one infill line on that ring - did you scale the object up? If not: what are your extrusion width settings?
Hello again.
I installed cura just about an hour ago.
And it rocks! It produces way better prints and its faster!
So i wont bother finding out the problem.
Thanks for your help kuraasu!
the ‘real’ download-link where you get the stl-file (and only that) is the one in the upper part of the page, where the filename is written, and not, I repeat NOT the shiny green buttom below. Sadly, many of the free hosting websites try to install some dubious software as “download manager” nowadays …
@fridh: I think thing:22043 is the same object, right? Just in case anyone else wants to have a look.

Kuraasu, thank you, I missed that link. When I see for the premium account on this site “Verdienen Sie Geld mit dem SpeedyShare Mitglieder-Programm”, of course, someone has to pay for it…
