Time estimation excessive  

New Member

Hello All,


I've a problem with the estimated times by PrusaSlicer.

In this case it estimates more than one day of printing :


When the file is ready to print via my Octoprint, the estimation is 3 hours :



After several prints I know that Octoprint is much closer to reality than PrusaSlicer.

In this case I will have something like 5 hours print.


The printer is an Ender 3.


Is there a settings I'm missing in the slicer ? One day off is quite a big difference.

Although I get excellent estimates from my PrusaSlicer for my MK3S, I also use the PrintTimeGenius plugin for my OctoPrint setup. https://plugins.octoprint.org/plugins/PrintTimeGenius/ This plugin gives me excellent runtime estimates. Down  to the minute, at least.

I know about the OctoPrint plugins.

Apparently I'm the only one to have this issue, it's not a big deal, but it's strange.

There must be a settings somewhere that I've wrong.


Octoprint    makes an error of ~ 0.5 x

PrusaSlicer makes an error of ~ 10 x

My PrusaSlicer estimates are usually within the ballpark.  Of course I use the I3 MK3S.

My guess is that something about the Creality config in PrusaSlicer is not dialed in correctly.
