Changing print speeds do not change the estimated time to print

When I make changes to the print speeds then re-slice my model the estimated time to print does not change. In my last attempt I increased all of the speeds by 50% but the estimated time to print stayed at 2 hours and 4 minutes. I would expect there to be some change.

RE: Changing print speeds do not change the estimated time to print

If the part is small, the nozzle is likely never coming up to your original (lower) speeds, so setting them higher will make no difference. Acceleration and jerk settings and physical limits come into play. Check the speeds out in preview mode after slicing. Linear "speed" is not directly proportional to print times

Did you ever find a reason for this? I am having the same issue. I NEED to make this piece print faster. At one point they were printing in 45 minutes and now I can't get it to change from 1:45. The print is not that small, about the size of a large matchbox.

RE: Changing print speeds do not change the estimated time to print

You don’t say what make and model printer you have, which is helpful for others to know in order to provide meaningful responses.

If you have a part that printed in 45 minutes and it’s changed to 1:45 it sounds like a different problem to what the OP in this old thread was asking.

Your issue deserves a new thread but a couple of questions come to mind:

Are you having the time change printing the same GCode as the original part? If so, has anything changed with your printer?

If you’re seeing the time change problem in the slicer, something must have changed in the settings. Double check the layer heights, infill type and percentage, number of perimeters, speeds, etc.

If you have the original .3mf file, load it into the slicer and see if it slices at your expected print time.

Cheers

I'm sure you already thought of this but slicer will honor max. speed.

I cant get speed settings in Prusa Slicer to change also.

However if you go to TUNE on printer while printing you can up speed by 200-250%.

I know this does not solve real problem, but you can get something done quickly.
