Interesting idea. However, how many solid layers would you make? If you do the usual 3-5 solid layers, I'm not sure that would be very useful as the total rotation would be very small.by Sound - Slic3r
Slic3r will use bridge speed and flow every time it is extruding in free air or over sparse infill.by Sound - Slic3r
Yeah, that's in the TODO. I need to implement an algorithm for detecting successful bridges.by Sound - Slic3r
CaptainObvious, you can either thicken those parts in the original model or use a slightly lower value for Perimeter Extrusion Width. The problem is that those parts are too thin for fitting two extrusions, so Slic3r switches to a single one. You need to make more room (in the model) or request thinner extrusions.by Sound - Slic3r
@PulsedMedia, having 1mm retraction with 5mm extra length does not make any sense...by Sound - Slic3r
@GregFrost, the relationship between flow rate and resulting shape does not vary whether it's used for perimeters or infill, so the math you see applies to any kind of extrusion (except for bridging). The diagram I showed says nothing about the spacing of two adjacent toolpaths, so I wonder why you think it would lead to gaps. This is the model that links flow rate and expected width. Then thereby Sound - Slic3r

Thank you Greg. Also, nice to read from you after long time. I'll wait a bit to hear opinions from other people who have partecipated to this thread. I'm not sure I would recommend a calibration procedure based on the measurement of a single-wall object since the absence of an inner loop would not reproduce the (possible but not very known) outwards shift that the outer loop gets when it's extruby Sound - Slic3r
We could probably do something right now, while we figure out the bigger picture. It looks like there are two quick possible workarounds for now: An inset value (in mm) to apply to the outer loop (in addition to extrusion_width/2 which is already applied) An additional extrusion multiplier to apply to the outer loop (to allow user to reduce flow as Sublime proposes) I wonder what the pros andby Sound - Slic3r
@Replace, as Sublime said the different spacing on first layer depends on first layer extrusion width, which is different (fatter) for first layer by default. You can just set it in the "Advanced" section in "Print Settings". If you set it to 0 (auto) it will be equal to the one used for the other layers.by Sound - Slic3r
Hello! I have been reading this thread and first off I'd like to thank you for this research work. Your comments, diagrams and thoughts are much more valuable than any code patch. I really hope we can all together come to a solution in terms of algorithms, needed config options, calibration procedures. Making everything configurable by adding tons of options is not the ideal solution, unless we pby Sound - Slic3r
Hello! First off, sorry for not being very present in this forum. I try to read everything and work on the issues, but I rarely have time to answer and partecipate in the threads. I'm very focused on the documented issues that are reported through the GitHub issue tracker. Still, thank you for your testing and reporting work, it's very valuable.

...I'd put more effort into describing and discussing the problem before coming to a proposed solution. Pictures, videos, observation, whatever helps people understanding what the problem is. I don't really get what do you mean by "the first layer infill gets distorted". Personally, I set the First Layer Speed option to 30mm/s, so that everything on the first layer gets printed at that speed, reby Sound - Slic3r
If you want to see the logic behing cooling, this may be useful:by Sound - Slic3r
Hello! Yes, the Perimeter Speed applies. The first layer (good question ) is the first loop. Well, if you print with some Bottom Solid Layers, those are not spirals so they are regular layers. And yes, single-wall vases often need much cooling... enjoy and post picturesby Sound - Slic3r

If you set it to 0 it will compute an automatic optimal extrusion width based on your nozzle diameter and layer height. This applies to all of the "Extusion width" fields.by Sound - Slic3r
You can launch it using the --datadir option. For example: ./slic3r --datadir /Users/foo/Dropbox/Slic3rConfig However you can just make a symlink between ~/Library/Application Support/Slic3r (which is the default location) and your Dropbox folder. There are tutorials and utilities out there, and that's how I did for syncing my Slic3r presets across my machines - I have to say it works flawlesslyby Sound - Slic3r
I confirm there (was) a problem with non-ASCII characters in home path on Windows. Your debugging was right The issue should be fixed in 0.9.9-dev and I hope to release the new version soon. In the mean time, as a workaround, you can create a data directory in a path with only ASCII characters in it (like C:\Slic3rData or whatever) and launch Slic3r from the command prompt with the --datadir C:\by Sound - Slic3r
First layer extrusion width = 100% is not the same as First layer extrusion width = 0. If you read the tooltip closely you'll see that percentage value is not computed over the other layers' width but over layer height. So it will make a width equal to your layer height, which is not usually a good thing nor your goal. Set it to 0 like the other widths and you'll get the results you want.by Sound - Slic3r
Reef, the poor STL format sometimes causes loss of manifoldness at export time, even if your original mesh is correct. You can try exporting in OBJ format. I recommend to download the free Netfabb Studio Basic to quickly check whether a given STL file is valid or not. You can use that to double-check the Slic3r warnings if you suspect it's not telling the truth.by Sound - Slic3r
The 'scale' option in the G-code comments does not reflect the changes made in the Plater, as they only apply to single objects. It shows the global scale factor that you can supply using the --scale command line switch. I do agree that can be misleading (it's a leftover from the past), so I'll remove it from the G-code comments.by Sound - Slic3r
Ti consiglio di rimuovere le doppie barre lisce su Z perché ti creeranno fastidiosi grattacapi. Hai visto la TK-0? È un ottimo progetto, puoi prendere spunto anche da lì.

This is getting requested by many parties. I think it's only needed with badly calibrated machines. Adhesion problems and oozing problems should be fixed on their own, so I usually tend not to encourage workarounds to problems that have to be fixed at their origin...by Sound - Slic3r

Bed takes usually way longer to heat up, and you don't want to have plastic burning in your nozzle in the mean time. Anyway, you can just set temperatures to 0 and Slic3r will not emit any temperature-related command. You can also supply your commands in the start G-code procedure.by Sound - Slic3r
