UM2 Print time is much slower than my other printer?

[axislab 8]

I am trying to track down the setting that is slowing my ultimaker2 to nearly 2/3rds the speed of my other printers.

I seem to have about the same settings for both, but the print time is much larger on my UM2.

(please note, even if I change the minimum layer time, and travel to match the Prusa settings, it still was over a half hour slower on this file.)

Is it just the difference between one printer being 1.75, and the UM2 being 2.85?

Or am I missing a setting somewhere?

Fill density 30% vs 100% makes a bit of a difference

Of course I would forget to change that before taking the pic. I feel dumb.

BUT, I had changed that of course before. It is still 20 minutes longer on the UM when infill, layer time and travel are all the same...

Minimal layer time is much longer on the UM2. Travel speed is set faster on the Prusa. Bottom layer speed is set faster on the Prusa.

Prusa is a .4 nozzle.

That last picture I just took. I had the infill at 30, travel at 150 and minimal layer time at 5 on the UM

They are all the same now. still 20 minutes slower.

First layer time doesn't change it at all, less than a minute difference there.
