Obligatory "I got a 3d printer for Christmas" and I'm absolutely loving it, fell down the rabbit hole head first. However I'm currently dealing with an issue where my Neptune 4 Pro is slowing down to 7 mm/s when it is printing the outer walls despite being setup in Cura to print at 25mm/s. Filament is Overture PETG. Pictures show the Neptune touchscreen with the 7mm/s speed shown in the bottom left and a screengrab of the speed settings from Cura. Any help is greatly appreciated!
In addition to what other people are saying there are additional factors like minimum layer time. If you find that layers with less material are being done slower it might be because of this.
In general a well tuned profile will prioritize quality over speed. You can bump things up or use a more aggressively tuned profile but your results may vary.
Thank you for the extra info! Im going to start researching more about how to actually use my slicer and tune those profiles.
