For a long time I've been using a travel speed of 130mm/s, after building a faster printer I wanted to increase it to 200 (or more) and this actually increases the estimated print time substantially.
Odd, very odd, what could be the reason?

I have not seen that feature - I probably do not have a version of Slic3r that supports it. Not having a clue how it works, I am nevertheless wondering whether it would be possible to mark the area requiring the solid infill slightly inboard of the outer perimeter so the normal exterior perimeters are not included in the marked area?

Here's a couple images to show the issue:
As you can see the infill modifier splits the object and inserts a separate path structure in between:
This results in very obvious seams and probably creates a failure point for the part:
It would be better if only the infill would be affected by the modifier object, leaving the perimeters intact.

I have a suggestion (or perhaps I'm doing something wrong), I wanted to use the modifying object functionality to add 100% infill in some areas of an object to increase the strength of the part and prevent delamination; the problem is that Slic3r, instead of simply doing a 100% infill within the modifying volume it splits the object so that it creates perimeter loops on either side of the interse

I'm curious about what was the response to the request. Did you actually requested on github or here?
Since the config comments are exactly the config content, I suppose would be easy. I think may be useful as well.
I only posted it here, github gives me a headache...

With the filename, don't know what to say. I thing file management is a general issue, and if one is not able to keep files in the proper order, there are little chances that keeping an "inventory" of all the files on the plate won't be of too much help.
In normal circumstances you "assemble" a plate o parts that belong to the

Slic3r appends the total volume of plastic used to the GCode, open one file and, depending on what version you are using, you will find that information near the beginning or the end of the code.
Total print time would be nice, what I do now is to open the G-Code file in Pronterface and it tells me the estimated total time.

I was looking around for ways to improve interlayer adhesion (specially with ABS) and I had a thought, how about after a layer is completed have the nozzle move down very slightly (for example 0.05mm) and do a dry run over the part being printer, that is to say, just move over the previous path without extruding material, just reheating and compacting the underlying layer so as to improve the bon

I'm setting up a new workstation and after installing Slic3r I noticed that the plater tab buttons look wrong, not aligned, different heights, in general the UI looks wrong.
What could be the problem? It's a new computer so I may be missing something, but I don't know what.
It's the 1.1.7 version, on a Windows 7 64bits PC.
It seems to slice fine, so it's just a cosmetic problem.

I'm thinking of building a CNC hot wire foam cutter, looking around for options... none too good for what I see.
So I was thinking how difficult would it be to use a RepRap derived mechanics and electronics for this purpose? Or, ideally, if someone has already done it so wouldn't have to reinvent the wheel.
What I have in mind is to use a software like FoamWorks to generate the G-Code and then

One of the things I like about Slic3r is that it adds the entire print settings to the G-Code file, so that it is possible to reproduce them later on, I've found this to be extremely useful.
I was thinking that it would be nice to be able to, from Slic3r, select an existing G-Code file to change the print parameters according to the data stored on that file, easier than going item by item and le

The way I do it with something like that is I model the object with a wall twice the extrusion width, slice it and if it doesn't slice properly I fiddle with the perimeter extrussion width until it does, sometimes it's a matter of setting the extrussion width to 0.38 instead of 0.4mm, a very small difference.
As for clearance, I think it depends a bit on the printer, with mine I usually make a ga

I haven't had the time to test it yet, but version 1.1.0 has the option to use another object to define printing parameters of the actual printing part, I don't know if enabling or disabling bridges can be done that way.

Sorry for the confusion on the last post, I did play with the fill density at 70% but the pic shows it was clearly not near that. I attached one I ran at 1 and you can see the difference where the infill threshold is starting to affect the outer areas as they are separated from the main body.
Are you telling me that the print settings tab should have more options? I have been us

Ok I'm starting to get frustrated now that i cant figure it out. I've attached a screenshot of the fill settings and the result in the middle of the print as shown in pronterface. The first and last layers look and actually print 100%. I'm expoting g-code, using Windows Vista, Slic3r 1.0.0. Same result on any STL. I appreciate all suggestions.

It may also be possible that the temperature reading you are getting is too low and the actual temperature of the hot end is higher than what you set. Try reducing the temperature by steps and see when it becomes too low to print.

Well, fancy that, it's not a bug. I had an Ahaaa! moment (immediately followed with head banging against the table) when I realized that the reason the perimeters are not being generated for the first layer is because the first layer extrusion width is thicker than the perimeter width for the rest of the print. In this case I have a perimeter width of 0.3mm and a first layer width of 0.5mm, with

I was testing Slic3r 1.1.0 and I see the problem persists, here's a screen capture of the first two layers in Pronterface showing the issue.
On the left the first layer and you can see how the perimeters stop at the top when the surface against the print bed is only two perimeters wide. On the right you can see the second layer and here the perimeters are fully traced, but of course since the

It seems that everyone thinks that 1.75mm takes less force but as far as I understand this is not true. A certain volume of plastic going through a certain size hole at a certain rate takes exactly the same pressure regardless of the filament input size. Or to put it simpler, the nozzle diameter determines the pressure required to extrude not the filament.

I'm trying to print a GoPro mount that is sturdy and I cant get enough infill at the main transition to the mount. Even when I make infill 1 its really more like 70" eye balling it. Is there some setting I've got clicked that i dont realize? Shouldnt 100% infill be solid?

Not really sure what the question is, but with Slic3r you can set the width of the perimeters to match what the wall thickness on your part requires. If the value you input is smaller than the wall thickness it won't be included in the slicing, but keep in mind there's only so much thinner than nozzle diameter you can go before you hit printing inconsistencies.

I have assembled a RepRap from RS Comonents and everything seems ok, except when I start a test print, just a little PLA comes out of the extruder nozzle, then it stops.
The head temp is 200C and stays there within a few degrees.
If I run a manual test, by lifting the head out of the way of the bed, the extruder pumps PLA out in a fine stream which looks ok to me.

I downloaded both versions, 1.1.0 is very unstable, crashes constantly. The new features are great so I'll be eagerly looking forward to a stable version.

is it possible to exchange this piece?
Can you imagine what the reason was?
maybe too many ampere on the stepper driver?
Edit:
the piece is called: AMS1117-5.0V
could it be because of my powersupply?

There's another great use for this stuff, to clean up nozzles used with PLA! Or jammed hot ends for that matter.

Be careful with MEK
It's not MEK, it's Ethyl Acetate, a quick look in Wikipedia says it has low toxicity, it's even present in some foods.
It does seem like a great discovery, it should work really nice in prints with layers of less than 0.2mm thickness.
