Cure for The Common Curling: "The Brim" :)-D Here is a way to defeat curling/warping in your prints. The term might be taken, but I call it a "Brim." If anyone wants to coin a new term for this, make a suggestion ;) [img]http://i1014.photobucket.com/albums/af262/idolcrasher/492becd2.jpg[/img] [IMG]http://i1014.photobucket.com/albums/af262/idolcrasher/0045639f.jpg[/IMG] [img]http://i1014.photobucket.com/albums/af262/idolcrasher/909c77ba.jpg[/img] Using the program Slic3r I add a "skirt" of 5 to 15 loops at a "zero" millimeter distance from the object I am printing. http://slic3r.org/ This adds a brim (like a cowboy hat ;) ) that keeps the object "spot welded" to the plate and absolutely stops all warping and curling. The additional surface area, combined with the rounding of sharp points on the bottom layer denies any possibility of curling or warping from the bed. To remove the brim, you need simply fold the plastic back and forth, and it snaps off :) I hope to see this method implemented in the various slicing programs; as its own unique feature. Try printing with a Brim today, and see if it helps the quality of your prints ;) -Happy Printing IdolCrasher www.fabberforge.com https://reprap.org/forum/read.php?1,136147,136147#msg-136147 Sat, 05 Sep 2026 11:13:12 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,136147,487585#msg-487585 Re: Cure for The Common Curling: "The Brim" :)-D https://reprap.org/forum/read.php?1,136147,487585#msg-487585 elwood127 General Mon, 23 Mar 2015 18:28:39 -0400 https://reprap.org/forum/read.php?1,136147,486134#msg-486134 Re: Cure for The Common Curling: "The Brim" :)-D https://reprap.org/forum/read.php?1,136147,486134#msg-486134 joecross98 General Fri, 20 Mar 2015 13:20:46 -0400 https://reprap.org/forum/read.php?1,136147,480524#msg-480524 Re: Cure for The Common Curling: "The Brim" :)-D https://reprap.org/forum/read.php?1,136147,480524#msg-480524

i'm using Skeinforge through SFACT and Repetier Host,

anyone knows if the new skirt.py with grim works in this set-up ?

i've tried it and i get an error message when slicing:

skirt.py, line 270, in getHorizontalXIntersectionstable
euclidean.addXIntersectionsFromLoopForTable(loop, horizontalXIntersectionsTable, self.edgewidth)
AttributeError: SkirtSkein instance has no attribute 'edgewidth'

maybe i'm using incompatible versions of SFCAT and/or SKeinforge ? If so , where do i see which version i'm using ?

thanks for your guidance]]> Hugues General Sat, 25 May 2013 06:18:04 -0400 https://reprap.org/forum/read.php?1,136147,163451#msg-163451 Re: Cure for The Common Curling: "The Brim" :)-D https://reprap.org/forum/read.php?1,136147,163451#msg-163451 -------------------------------------------------------

I change skirt.py for a better brim.

Brim starts from outer diameter downto internal. Its better.

New code for skirt.py:

here is the skeinforce module I changed today. Now you have a parameter "Brim Width". If you use it, change the gap over perimeter to 0.5

Just replace your old skirt.py by this one and enjoy. :)]]> theodleif General Sat, 30 Jun 2012 21:20:46 -0400 https://reprap.org/forum/read.php?1,136147,140116#msg-140116 Re: Cure for The Common Curling: "The Brim" :)-D https://reprap.org/forum/read.php?1,136147,140116#msg-140116
