SolvedHow to get cura's time estimates closer to reality?
Posted
· How to get cura's time estimates closer to reality?
In this case it appears to be something in the Settings Profile but I'm unable to find it. Simply opening your 3mf file and slicing it I get a print time of 4:47.
Just switching to the Standard Settings profile (with infill adjusted to be the same as your settings) the print time drops to 3:09. Switching the infill to Grid results in a print time of 1:54.
So maybe something is going on with that settings profile, or maybe with the Creality Ender 6 definition or the Creality Quality files?
As an experiment - try using a stock profile like Standard/Draft with 20% Grid infill and see if it makes a difference.
The Grid infill results in a few lines of gcode. The Gyroid infill results in a bazillion lines of gcode because of all the curves. Part of what is going on may be a cumulative error when Cura attempts to add up the print times for all those short line segments. I have no idea if that may be true or not but in this case we can see that Grid v Gyroid makes a big difference.
This topic comes up a lot. For myself, the Cura estimated time versus the real print time is consistently within 12% of each other and Cura always over-estimates.

Thanks for looking at this.
I've now created a new profile, just copied the speed and accel settings into it, tried a few things and yes, they are indeed a lot more accurate now. Nearly spot on.
Very interesting.
I'll simply on from this new profile.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
