Slicing print times

itisnot_me · December 2018

I know that this is a known issue for slicers as they dont know the printers acceleration and jerk settings but can you set these values in the slicer so it can give a better printing time? I exported out the settings from the printer below.

I have both cura and s3d.

Yes you can:

first, enable visibility for all settings

second, enable acceleration control (in the speed category)

third, update the values in the slicer, with the values you want to use. that should help make the print time estimate more accurate.

oh god what did you make me do. Now i cant just go back to what i normally had shown without manually selecting it all.

Also on cura 3.6 you have to select the check box to bring those settings up.

From the settings above what do i put in the box? there are different settings for XYZE

I think that i figured out the acceleration settings but the jerk is my problem
print acceleration 800
travel acceleration 1000

cura currently has jerk at 20
and travel jerk at 30

Set print jerk and travel jerk both to 5

itisnot_me · December 2018

@rhaub101 for the future how did you come up with the 5

That’s what I use and estimates and actual are within minutes.
