Cura 15.01 - Printing Time Calculation

Recommended Posts

Posted · Cura 15.01 - Printing Time Calculation

Printing Time Calculation:

 

I noticed that the printing time seems to be calculating oddly now. I loaded up a plate of parts at 50 mm/s and it shows a printing time of 2 hrs 0 min, 1.21 m, 10 gram. If I change the speed to 100 mm/s however the printing time only drops to 1 hr 54 minutes, same m & gram. It seems like doubling the speed should have a bigger impact on overall print time. (I would expect nearly half)

This is with the default settings immediately after installing 15.01. (20 mm/s bottom speed, 0.0 for all other speeds under Advanced)

Member @dirkdirk pointed out:

What is your "minimal Layer time"? This could have a large effect on printing time.

To which I responded:

Aha, it was set to the default time of 5 sec, decreasing it to 0 changes the print time down to 1 hr 41 min (at 100 mm/s) so it is coming into play. Also it defaulted to "print one at a time", changing to print all at once decreased it to 1hr 39 min (100 mm/s).

FYI, The plate of parts is from the UM2 Bearing Filament Guide (626 version).

Maybe the printhead can't reach the required speed? So more speed will give no advantage.

(acceleration and deceleration)
