Autospeed howto
Hi,
Is there any help on how to set auto-speed? I tried to setting all speeds to "0" then set the "max print speed" to some value (50mm/sec) -- which worked, almost. Caused the gaps remaining gaps, for example. Then I've set back the "gap fill speed" to same value, which makes the gaps filled, true, but then the entire print became dead slooooooooow...
So, is there a guide how to use auto-speed properly?
(p.s.: I am using PruseSlicer with a Creality printer, if this aspect is important)
Thanks in advance

Simple answer is its broken. https://github.com/prusa3d/PrusaSlicer/issues/2746

Should also add that if you want autospeed then try Super Slicer. As it actually works.
However do NOT try and just blindly think that your PS profiles will just work the same. They wont. While its based on and VERY similar there are several differences in the way settings are configured and work, enough to be gotchas if you don't check things properly.

Oh, bummer. Thanks!

I use Auto Speed and find it very handy. I don't consider it broken but rather, just not well understood, many features in slicer are not well documented and I think that plays to that effect.
It works as intended, in fact its purpose originally was to keep the extruder pressure as close to constant as possible. If used correctly it can have several very desirable effect. I don't have time to write a tutorial on this, but maybe these tips will help you move forward.
For starters make sure to turn off "Enable auto cooling" when using Auto Speed settings, they can and will conflict. However just start off with "Enable auto cooling" off, as it can work well when turned on with Auto Speed settings to produce tall thin parts. You will want to learn to control auto cooling as well.
Remember that Auto Speed settings are attempting to find the happy speed for constant extruder pressure, for all the features you specify. This means that every feature you set the speed to Zero for, with the exception of Gap Fill, will be taken into account. If we're using the Bunny model from the gallery as an example, it has larger and smaller areas, some of those areas qualify as Small perimeters, requiring slower speeds, some areas are comprised of types of infill requiring slower or faster speeds to print successfully, they have to be considered.
Keep in mind that just because you can set all the speeds to Zero to be controlled by the Auto Speed settings doesn't mean you should. be selective, and use a good understanding of your plastics, and you will see some great results using Auto Speed settings. Playing with them is probably the best way to get an understanding, and I might suggest starting off conservatively, then adding another feature and so on and see how it effects your results. You can test them in slicer by selecting the speed view from the lower right menu.
Here's a post with an example of a user that used Auto Speed and cooling to correct an issue, and produce a desirable result. maybe it will help you.
