# Why can my printer display remaining time but OctoPrint can't?

The Prusa i3 MK3 displays the remaining printing time right from the beginning.

From about 8 prints until now, I would say that this time is quite reliable.

Octoprint, however, does not display the remaining time initially and is then far off.

Why doesn't Octoprint just take the remaining time from the printer and display that? Or can I change a setting so that it does?

• I'd strongly suggest using the PrintTimeGenius plugin. It's accurate within a few minutes. – tedder42 Feb 14 '19 at 19:22
