K1Max speed vs K2

Hello
I have a K2 and a K1Max.
I have a part I print and the K2 prints it in 2.5hours but the K1 takes 4 hours.
Both have the same speed settings.
Anyone point me in the right direction to figure why the K1Max prints so much slower?
Thank you.

Welcome to the Creality Forum…! Creality

Just for starters check this setting and see if it’s the same…

If the printer is set to print at a higher quality such as 0.16 or 0.20 then it will take a little longer than a printer set at 0.24

Other settings such as infill, wall loops, etc can affect the time…

After slicing the part you get an overview how long it takes to print walls, infill and all other things. Check what parts differ much between the prints and check the settings. Something must be off…
