Changes in path planning

[Food24 0]

Dear all,

i have a question very difficult for me: It is possible that by changing some printing variables such as (but not only) print speed (feed rate) a different path of the printer is planned by firmware Marlin ?. If so, should be possible that this takes more time for printing.

My question arise from some results that i obtained in the last days. Particulary, I obtained total (measured) printing time of 150 s, 180 s and 150 s by using print speed of 11, 16 and 21 mm/s. If the setting of other variables are exactly the same i cannot explain this. So, would be possible that at print speed of 16 mm/s a different path is obtained producing an increase of printing time.

Can anyone help me to explain this observation ?

Thanks
