SOLVED Ender 3 stops for a while mid-print

[Luxfire 0]

Hi guys,
i'm using Solid Edge to design and Cura to send file to my Ender. i've printed a lot with this setup, but since week ago my printer just stops in one place for 4~7 sec producing noise like blocked stepper motor and after that time it prints normally for some time, and again stops. 
First i noticed it while i changed profile in Cura from CR-10 to Ender 3. on Ender 3 profile stops and a loot of mess occured so i changed to CR-10 (on CR it printed well until this week)
I didnt modify anything in my software/hardware. 
Some ideas or experiance with that error?
Thank for Your guidance

#SOLVED

Ender 3 stops between each layer. that's because of Cura 4.1 
in my case changing Z speed from 0 to 30 works very well and my printer no longer stops, just printing as well as before.
