I think this may be wrong when the resulting cruise speed is lower that entry or exit speed.

Now it should be correct. There was some audible crackle which is now gone.

Dün geceki uzun baskı işleminde herhangi bir sorun olmadığı doğrulandı.

HELLO,

Do you think this is the reason for this situation that occurs at regular intervals?

There's a regular gap like this in only one direction. My old printer, Marlin 1.1.7, had a perfectly smooth, gapless grid fill! 😃

What I did:
I used PLA,
I increased the temperature and fill flow rate, but there's still very little gap left, there's still a gap :(
