![]() ![]() 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. ![]() You can test them in slicer by selecting the speed view from the lower right menu. 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. be selective, and use a good understanding of your plastics, and you will see some great results using Auto Speed settings. 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. 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. This means that every feature you set the speed to Zero for, with the exception of Gap Fill, will be taken into account. Remember that Auto Speed settings are attempting to find the happy speed for constant extruder pressure, for all the features you specify. You will want to learn to control auto cooling as well. 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. ![]() I don't have time to write a tutorial on this, but maybe these tips will help you move forward.įor starters make sure to turn off "Enable auto cooling" when using Auto Speed settings, they can and will conflict. If used correctly it can have several very desirable effect. It works as intended, in fact its purpose originally was to keep the extruder pressure as close to constant as possible. 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 doesnt seem to change if we set perimeter overlap 0. set spacing (0.8) base layer height (0.3) perimeter overlap (100) First layer flow ratio (100) With these values the indicated EW 0.8644. Nobody answered to the person who posted on the Prusa forum why. what formula is used to calculate the extrusion width if inputs are. Then the print has the gaps in those locations because the printer very accurately prints as it is commanded. You can clearly see the gap between start and end of each layer on the perimeter in the slicer. RE: Autospeed use Auto Speed and find it very handy. It is exactly what this person is describing in this post for Prusaslicer. ![]()
