Topic: Using brims in Repetier

I was always in the habit of using brims to keep prints from curling, but since getting the latest version of Repetier the brims don't make contact with the object. They are outside of the object but are like 1 or 2 lines short of touching it. Is there a setting that makes sure it touches the first layer of the print?

Under brim settings there is an offset option that value specifies if it touches or not. Should be zero to touch. Also make sure you are selecting to print a brim and not a skirt. A skirt does not touch and is meant mainly just to get a good flow before printing.

Re: Using brims in Repetier

I will look for the offset option. Doesn't seem there should be an option like that? If the brim doesn't grab the item's edge what good is it?

Some people have used a brim to create a wall around their model to trap heat and cut down on deforming and related issues. The brim can be as thick and as high as you want it.

Where is the offset option? In (slic3r setting/printer settings/skirt and brim) there are loops, dist from object, skirt height, and min extrusion length for skirts. And for brim there is only one number. Brim width.

I hope it's supposed to be in a different setting?

I think you're confusing brim with skirt.  A skirt can be set a certain distance from the object and as many layers high as you want.
The only setting for brim is how far it extends from the object.  It should be touching the print and I am unaware of any settings to change that.  Since Brims and skirts are a function of Slic3r I fail to see how upgrading RH would change anything.  Unless you also upgraded slic3r at the same time.  If that's the case, what version of Slic3r are you using now?

Re: Using brims in Repetier

When I updated Repetier my slicer settings remained from before so I assume it is still there from before. How do I check version number?

Re: Using brims in Repetier

What could be keeping the brim from touching the object? I keep it set at 3mm width most of the time.

The space between brim and object appears visually in Repetier as well.

Post a screenshot of the settings window in your slicer for the skirt and brim.

Re: Using brims in Repetier

Could it be the skirt and brim are interfering with one another? Maybe I need to put skirt out further or set it to 0 distance?

Or possibly if that isn't the issue maybe use a skirt in place of a brim and increase the loops?

Re: Using brims in Repetier

I extended the skirt outside the brim and in repetier anyway the space between brim and object appears gone. Will test print now.

Re: Using brims in Repetier

Click on help it'll give you the version number.  There are known bugs in certain versions and 1.1.7 seems to be the worst.  The good news is that it's easy enough to revert back and keep the new version of RH.

Re: Using brims in Repetier

Try setting minimum extrusion length to 150. Right now your telling it the minimum to extrude is 0 which it is doing.

I could be wrong but I think that setting only applies to skirt and its brim that's causing the issue.
You might want to look at your extrusion widths in the advanced tab of your slice profile.  I don't remember if there's a separate extrusion width setting for things like brim.

Re: Using brims in Repetier

Well in that preview I see what looks like a 3mm brim. Maybe set the brim for 10mm would get what you are looking for.

Re: Using brims in Repetier

I set a 8mm brim with a 9mm skirt and the first layer printing now is correct. Weird. I would think if anything the issue would appear on the edge of the brim and not the object when the brim and skirt are both set to 3mm or some other common value. I guess there was a conflict.

Re: Using brims in Repetier

I don't typically use brim, but it is kind of a one or the other type of thing.  If using a brim there is no real need for a skirt as the brim will purge the nozzle.  Unless you use a tall skirt for other reasons mentioned earlier.

Re: Using brims in Repetier

I use brim all the time on just about everything I print.  First of all I want to mention here that Brim and skirt have NOTHING to do with Repetier, they're functions of the slicing engine.  IN this case they're functions of either Slic3r or Cura,

In slicer, if you select a brim value, you should disable the skirt by putting a value of 0 in the skirt loops.  The distance fro object value only applies to the skirt.  It will have no effect on the brim.

This brings us to Cura.  The latest versions of Repetier now include Cura, The Cura engine has a selectable option under "Adhesion Type" where one can select either skirt or brim.  The Cura brim doesn't always touch the object all the way around.  Sometimes, it only touches the corners and the res of it is offset by a millimeter or so.  Nevertheless, it's still effective.

So is it possible that the user may be slicing with Cura instead of Slic3r ?

Re: Using brims in Repetier

His screen shot does show slic3r so I would think that would be the one he is using and setting up
If he was running cura slicer then its settings would open when configure was clicked.

not necessarily - i use both in slic3r with no problems, but - my numbers are not the same for both....

skirt is 1 loop at 8mm distance, brim is 3-5mm wide...depending on the size of the item being printed and whether or not there are sharp or rounded corners...
granted, the skirt isn't really necessary when doing a brim, but I just never bothered to turn it off...I kinda like knowing where on the bed all the parts will be printed...the skirt gives me a quick visual of where everything will be, if I need to relocate, I kill the print before it actually starts on the parts - move things as needed, re-slice and start again.

could it possibly be that with both set to the same number it was causing a conflict? Slic3r didn't know whether to do a brim or a skirt?

That's what I figured however I expected that conflict would have occured 3mm out from object and not between the object and where the brim is supposed to start.

Re: Using brims in Repetier

I'm surprised no one did any tests to see the exact behaviour of the brim and skirt depending on settings.

A log wile back I was trying to understand the relationship between these two and I did a few slicing tests.  Here is the link to those results.  Hopefully this will clear up some of the misunderstandings regarding this.
