Different printing durations

Recommended Posts

Posted (edited) · Different printing durations

In Cura 4.1 I prepared the same items for printing with the UM 2+ and the UM3. I made the same preferences (layers, speeds, shells, etc.), but for the UM2+ I get a printing time of 100 min and for the UM3 it's 170 min. And while printing, the UM3 is visibly slower. Does anyone else have this problem or an idea how to fix this?

The printhead in the UM3 is much heavier than that of the UM2+. To maintain good printing quality, settings that affect the speed the head achieves are different between the two, eg the maximum accelleration.

 

Simply put, the UM2+ is a faster printer than the UM3.

Thanks for your answer. This sounds plausible, although I didn't expect, that it would almost double the printing duration.

I'll make a test with long straight lines, where the acceleration shouldn't have that much influence and check, if the speed of the printhead will be the same.
