I saw this a few months back, and now that I have the space, and permission, to share it, I figure I'd share a cool way to fix the obnoxious discrepancies between estimated print time, and actual print time. Thank you reddit user Addictedtocomedy for posting this info.
So, Cura's estimated print time is based off of it's default acceleration values. In case you're not familiar with acceleration values, they are the main cause of all ringing. I believe I set the DP5 around 1500(it's been a while), but Cura's is something stupid like 4000. This difference really adds up in overall print time. Another value that affects it is jerk, which is how fast the printer changes direction. These 2 values can throw off an estimated 3 hour print by an hour or more.
here's the link to the full article, with instructions on how to set the values for more accurate estimates. If you have a reddit account, please throw them a like if you think this is helpful information.
To get your printer's acceleration and jerk values, go into motion control and scroll down to view or change the value.
