Filament "Profiles" Lacking/Method Flawed?
Hi All,
I've got a Mk3, originally (and still) have a Delta with Duet firmware.
On the Delta I used S3D, where a profile included details such as speed, cooling, temperature, retraction, multiplier etc.
What I can't understand with Slic3r PE, is that all the filament profiles only seem to change temperature, multiplier and cooling,
So it seems to me (unless there's some hidden magic), that the MK3 will try to print flex filament at the same speeds as PETG, PLA, ABS or anything else.
Same goes for retraction, which seems set the same regardless of the filament selected.
I've found speed and retraction to be 2 fundamental things that need changing "per filament".
Am I missing something here, or is that really the case? I can only see a workaround of setting up a new "print setting" also for each filament to handle the changes required to speed....and also a new "printer setting" per filament to handle changes to retraction.
Surely if that's the case...it makes the point of having pre-defined filaments completely irrelevant?
Is it just me, or?

Hi Benjamin,
every slicer has a different way of working, and most makers, also have their own ways of working.
The speed settings currently change with the layer heights.
there is nothing to stop you creating new profiles that match your preferences.

Hi Joan,
No I agree everything works differently.
I suppose my point is that to make all the changes that are required to tune-in a filament, it's not just a filament profile that needs creating/modifying.
Some of the settings that are pretty much entirely filament specific are not under "filament settings" but spread across the other categories too.
So in Slic3r, the process has to be :
1. Making a profile for the filament - i.e. temp, cooling and multiplier.
2. Making a new print setting - for speeds (which are mostly filament dependent), other settings in this section are purely "print quality" related.
3. Making a new printer setting - for retraction (which is entirely filament dependent)
Am I really alone in thinking that speeds and retraction settings should be re-located to "filament settings" ?
That would then leave "print settings" entirely for print-quality type decisions....e.g. layer heights, support, perimeters etc. and "printer settings" for more hardware-related settings like overall build volume, firmware etc etc.
It just seems really odd I have to have print and printer settings for all my filament settings - just to change speeds and retractions...when most all else in those sections stays the same for every filament.

I had a surprise after switching back to Slic3r 1.40.0 when I decided to try printing Colorfabb XT-CF20. Based on prior experience, I had all sorts of problems printing exotics, so was prepared for the worst. I thought I'd try the Slic3r XT-CF20 profile and work from there. I was surprised when it worked the 1st time, though very slowly. I looked through the Slic3r settings and was puzzled that all of the print settings were unchanged. I then noticed the Filament Settings-> Max. volumetric speed setting was 1, compared to 8 for PETG and 15 for PLA. This basically controls the amount of filament being pushed through the hot end, controlling "speed" in a different way. My understanding is far from complete, but I believe it will print at up to max speeds as shown under Print Settings but not to exceed the maximum filament flow. If I'm understanding correctly, this is really the important consideration, not the speed of nozzle movement.
I do find that I still need to create Print Settings for some materials (e.g. Colorfabb XT) for best results, but these tend to be "fast" versus "slow" settings such as speed and acceleration, so can still be used independent of the filament settings. A bit of a middle ground, allowing exotics to be printed without creating a full profile for each, and generics to print in fast or slow modes depending on quality-versus-speed choices.
Every slicer seems to have at least a few aggravations with regards to groupings. Slic3r's groupings make the most sense I've found so far. I've got a bunch of filament profiles, and a relatively small number of print setting (quality) profiles.
