lowering printing speed decreases printing time?

[neep 0]

Hi all. I just noticed that at some printing speeds, the time calculated doesn't make sense. For example, for one print, when I set it to 50mm/s, 2h33m is calculated, and when I set it to 10mm/s, printing time is now /reduced/ to only 1h45m. How can this be?

hi,

cura calculates the maximum speed per layer by the cooling time per layer.(Minimum layer time in Advanced tab) default is 5sec. I think here is the problem. Sometimes it is better if you want to print small parts faster when printing the part 2x at the same time. (Print all at once )

Also with the minimum layer time taken into account the faster print should not need more time... maybe the same amount of time but not more (assuming the minimum layer time to be the same for both slices).
